Abstract

The obscure species Strophopoda aprica Van Duzee, 1921 is redescribed. Calidroides, n.gen., is erected to accommodate the type species C. schaffneri, n.sp., from Arizona, Texas, and Mexico and C. negro, n.sp., from southern Mexico. Chlamyopsallus, n.gen., is described to accommodate the type species, C. lycii, n.sp., from the western portion of the Mojave Desert of southern California. Two new species of Pseudopsallus Van Duzee are described, P. tiquiliae, n.sp., from southern California and P. greggii, n.sp., from New Mexico and southwestern Texas. Systematic relationships in the Phylini and Pseudopsallus are discussed and digital habitus illustrations, illustrations of male genitalia, scanning micrographs of diagnostic features, and new distributional records are provided.

INTRODUCTION

Kelton (1965) reinstated Strophopoda Van Duzee, 1916a from synonymy with Chlamydatus Curtis, 1833. He maintained that the male genitalia of the two genera were similar, but noted that the head shape, detached pulvillus, shape of the ostiolar peritreme, and white cuneal apex of the type species, S. aprica Van Duzee, 1921, were unlike those of any species of Chlamydatus. Our study of North American Chlamydatus (Schuh and Schwartz, 2005) supports Kelton's assertion that Strophopoda and Chlamydatus are separate genera. Herein I document that the male genitalia of the two genera are unique and provide a revised diagnosis of Strophopoda. Additionally, evidence is presented to support the erection of two new North American phyline genera. One genus will accommodate two new species originally thought to be congeneric with S. aprica and another will accommodate a new species with a habitus superficially similar to species of Chlamydatus and Megalopsallus Knight, 1927.

Stonedahl and Schwartz (1986, 1988) revised Pseudopsallus Van Duzee and described several new species in the genus. Two taxa that cannot be accommodated in any known species from the desert southwest are herein described as new for specimens found in the holdings of several institutions. The generic diagnosis of Pseudopsallus must be reformulated in response to the inclusion of the new species.

Complete descriptions, color digital habitus figures, illustrations of the male genitalia, and detailed distributional information for all the included taxa are provided. Terminology and abbreviations for the male genitalia of the Pseudopsallus species follow those given in Stonedahl and Schwartz (1986). Species measurements (in millimeters) are given as the mean and range (in parentheses) for 10 specimens of each sex, taken from across the distributional range, unless otherwise indicated. All scanning electron micrographs are of males, except for Chlamyopsallus lycii, for which the female is provided. Localities for the specimens used in the dorsal habitus photographs are noted in the “specimens examined” and “paratypes” sections of the species treatments.

STROPHOPODA VAN DUZEE

  • Strophopoda Van Duzee, 1916a: 216 (n.gen.).

  • Type Species:

    Strophopoda aprica Van Duzee, 1921 by original designation.

    Revised Diagnosis:

    Distinguished from other Phylini by small, elongate, body; predominately black coloration, body surface moderately shining (fig. 1), and vestiture of stiff, black bristlelike simple setae (fig. 3C). Macropterous; clypeus protruding, with distinct basal furrow (fig. 3B); vertex with obsolete transverse basal carina (fig. 3A), vertex width not sexually dimorphic; eyes relatively small, not bulging, posterior margin straight, narrowly separated from anterior margin of pronotum; antennae with slight sexually dimorphism, diameter of segment 2 slightly greater in male than female, segment 2 slightly shorter than width of head across eyes; pronotum with lateral margin nearly straight; evaporative surface of metathoracic scent gland reduced, ostiolar peritreme flattened and situated on ventral surface (fig. 3E); claws small, curved, base prominent, pulvillus large, apically detached from ventral margin of claw, parempodia setiform (fig. 3D). MALE GENITALIA (figs. 2, 3F): vesica composed of single untwisted strap, region distal to secondary gonopore a single strap with length equal to one-quarter entire length of vesica; secondary gonopore relatively large, distal margin broadly rounded, without area of attenuation, proximally with large, striate gonopore sclerite; phallotheca without distinctive features; left paramere conventionally phyline; right paramere with attenuate apex.

    Discussion:

    Carvalho (1955) synonymized Strophopoda with Chlamydatus. Kelton (1965) restored Strophopoda, correctly noting the features detailed in the revised diagnosis above. Specifically, the head with a produced clypeus, obsolete transverse basal carina of the vertex, and relatively small eyes; the large apically detached pulvillus; the reduced evaporative surface and flattened ostiolar peritreme of the metathoracic scent gland; and the white cuneal apex are not found in any species of Chlamydatus. However, I do not agree that the vesica of Chlamydatus and Strophopoda are similar (Kelton, 1965). The unique gonopore sclerite, extensive apical membrane, and straight nonspinose vesical strap distal to the secondary gonopore will distinguish Strophopoda from other North American phyline genera.

    Strophopoda aprica Van Duzee Figures 1–3

  • Strophopoda aprica Van Duzee, 1921: 132 (n.sp.).

  • Diagnosis:

    Recognized by the small parallel-sided body, black coloration, moderately shining surface, and bristlelike black vestiture (figs. 1, 3C). Differs from other small black Phylini by the conspicuous discrete pale yellowish white markings on antennal segment 1, vertex (fig. 1), corium, cuneus, membrane vein, femora, and tibiae; the small claws with large detached pulvillus (fig. 3D); the flattened ostiolar peritreme (fig. 3E); and the male genitalia with a single strap, large striate gonopore sclerite, and conspicuous apical membrane (fig. 2).

    Redescription:

    Male: Small, parallel-sided, macropterous; total length 2.48 (2.38– 2.59), length apex clypeus-cuneal fracture 1.62 (1.50–1.75), maximum width across hemelytra 1.01 (0.91–1.08). MEASUREMENTS: Head width 0.60 (0.58–0.61), vertex width 0.30 (0.29–0.33), antennal length segment 1: 0.18 (0.16–0.19), 2: 0.54 (0.48– 0.56), 3: 0.36 (0.31–0.39), 4: 0.23 (0.21– 0.25), labium length 0.81 (0.79–0.84), pronotum width 0.83 (0.80–0.85), pronotum length 0.37 (0.35–0.39). COLORATION (fig. 1): black with pale yellowish white markings as follows: antennal segment 1 apically, medial spot on vertex, narrow line distally on corium, cuneus and adjacent membrane vein apically, femora distally, and tibiae except for large black spots at base of spines. SURFACE AND VESTITURE: Dorsum moderately shining, impunctate, with numerous moderately long, reclining, bristlelike black simple setae. STRUCTURE: Corial margins nearly parallel-sided; frons gently rounded, clypeus clearly visible from above; anteocular distance equal to twice diameter of antennal segment 1; head projecting below eye by twice diameter of antennal segment 1; labium reaching apex of hind coxae. GENITALIA: As in generic diagnosis (figs. 2, 3F).

    Female: Conformation and coloration nearly identical to male; diameter of antennal segment 2 slightly less than in male. Total length 2.53 (2.33–2.63), length apex clypeus-cuneal fracture 1.70 (1.60–1.81); maximum width across hemelytra 1.09 (0.91–1.18), head width 0.60 (0.58–0.61); vertex width 0.30 (0.29–0.30), antennal length segment 1: 0.18 (0.16–0.23), 2: 0.50 (0.45–0.54), 3: 0.34 (0.31–0.39), 4: 0.23 (0.21–0.25), labium length 0.85 (0.81–0.88), pronotum width 0.86 (0.83–0.88); length 0.38 (0.36–0.39).

    Hosts:

    Calidroides, new genus

    Type Species:

    Calidroides schaffneri, new species.

    Diagnosis:

    Within the Phylini recognized by the conspicuous pale, laterally produced knob on the propleuron anterior to the coxal cleft (fig. 4A, B); the black head with a conspicuous pale spot on the frons near each eye and sometimes with an additional medial spot; the generally unicolorous pale tibiae without dark spots (fig. 1); evaporative surface of metathoracic scent gland present only on posterior margin, ostiolar peritreme flattened and situated on lateral surface (fig. 4C); claws small, curved, base prominent, pulvillus large, apically detached from ventral margin of claw (fig. 4E); and male genitalia with a somewhat broad single vesical strap without a basal twist and abruptly attenuate distal to the secondary gonopore, strap sometimes with spinules adjacent to secondary gonopore and or apically, without gonopore sclerite (fig. 2). Of the small black phylines associated with angiosperms, most similar to Chlamydatus and Strophopoda. It is distinguished from the former by the form of the head, pretarsus, and vesica, and from the latter by the concolorous tibiae, longer antennal segments 2 and 3, and the structure of the vesica.

    Description:

    Male: Small, moderately elongate, parallel-sided or tapered distally; range total length 2.08–2.50, range apex clypeus-cuneal fracture 1.45–1.68. COLORATION (fig. 1): dorsum either entirely black with a few conspicuous pale areas on head and antennae or dusky orange brown with black head and pale temporal spots; antennae black, segment 1 with a narrow white distal annulus, segment 2 sometimes broadly pale; legs pale yellow or pale orange, sometimes femora darkened basally, tibiae without black spots at base of spines, tarsi dark. SURFACE AND VESTITURE: Impunctate, smooth, moderately shining; vestiture composed of moderately densely distributed, recurved, shining, golden, simple setae of moderate length (fig. 4D). STRUCTURE: Head vertical, strongly projecting beyond anterior margin of eyes, frons tumid (fig. 4A), clypeus clearly visible from above; eyes small, separated from anterior margin of pronotum by distance equal to diameter of antennal segment 1; antennae of moderate length, segment 2 longer than width of head, slender, cylindrical; segment 3 subequal in length to segment 2; labium relatively stout, extending from apex to middle of middle coxae (fig. 4A); pronotum trapeziform in dorsal view, sometimes campanulate; laterally produced knob on the propleuron anterior to the coxal cleft (fig. 4A, B); evaporative surface of metathoracic scent gland reduced, present on posterior margin only, ostiolar peritreme slightly protruding and situated on lateral surface (fig. 4C); hemelytra parallel-sided or weakly converging posteriorly; claws small, curved, base prominent, pulvillus large, apically detached from ventral margin of claw; parempodia setiform (fig. 4E). GENITALIA (fig. 2): left side of genital segment with clump of five bristles (fig. 4F, G); vesica composed of single, untwisted, S-shaped strap, region proximal to secondary gonopore somewhat thickened and sometimes with spinules, region distal to secondary gonopore strongly attenuated with spinules near gonopore and with length equal to one quarter entire length of vesica, apex either narrow without spinules or somewhat thicker with spinules; secondary gonopore heavily sclerotized, relatively small, circular, distal margin broadly rounded, without area of attenuation, proximally without gonopore sclerite; phallotheca without distinctive features (fig. 4F); left paramere conventionally phyline, but with lateral protuberance in dorsal view (fig. 2D,E); right paramere somewhat rounded (fig. 2C).

    Female: Body only slightly more ovate than in male; macropterous with apex of abdomen reaching to apex of cuneus in lateral view; coloration and vestiture similar to that of male; antennal segment 2 more slender and more strongly tapered toward base than in male.

    Etymology:

    Derived from the similarity (-oides) of the vesica, in profile, in the type species schaffneri to the avian sandpiper genus Calidris (especially C. ferruginea, the curlew sandpiper). Gender masculine.

    Discussion:

    The pretarsal structure of Calidroides is similar to that of Strophopoda, Macrotylus Fieber, 1858, and Nicholia Knight, 1929. The concolorous tibiae, longer antennal segments 2 and 3, and the structure of the vesica will readily distinguish the new genus from Strophopoda. Macrotylus is easily distinguished from Calidroides by the more bristlelike vestiture, the more produced clypeus, the strongly tumid frons, the slender labium, the absence of a blunt precoxal protuberance on the propleuron, a much longer J-shaped vesica, and the elongate right paramere. The anterior portion of the propleuron in Nicholia is more tumid than is found in other Phylini; however, this structure is never developed into a knoblike protuberance as in Calidroides. The former genus also has a much larger body size (about twice as long) than the new genus.

    One female from near Totolapan, Oaxaca, Mexico (TAMU) with contrasting pale and dark coloration may represent an additional new species of Calidroides, but I decline naming it until males are available.

    The only host recorded for this genus is Allionia incarnata L. (Nyctaginaceae) from Presidio County, Texas.

    Etymology:

    Named for Joseph C. Schaffner, collector of the holotype and most of the paratypes. Over his long career at the Department of Entomology, Texas A&M University, Joe has personally amassed undoubtably the best collection of Mexican and Texan plant bugs. This is one of many new species of Miridae that have been “discovered” because of his efforts.

    Host:

    Allionia incarnata L. (Nyctaginaceae), trailing allionia, four-o'clock, or windmills is the only known host.

    Distribution:

    Southern Arizona and Texas as well as the western and eastern states of central Mexico.

    Chlamyopsallus, new genus

    Type Species:

    Chlamyopsallus lycii, new species.

    Diagnosis:

    Recognized by the small, highly polished, shining black body with pale yellow appendages (fig. 1); long, suberect, bristlelike, black dorsal setae (fig. 5G,H); black tibial spines; apical black bristles on the fore coxae and hind femora; apically black tarsal segment 3; length of antennal segment 2 less than width of head; conspicuous sexual dimorphism with the male elongate and the female ovate (fig. 1); the relatively short, apically bifurcate vesical strap barely extending beyond the distal margin of secondary gonopore, and the broad secondary gonopore (fig. 2). Similar in size and or coloration to some species of Chlamydatus and Megalopsallus. Chlamyopsallus differs from all Chlamydatus spp. by the black, bristlelike dorsal vestiture and the shorter portion of the vesical strap distal to the secondary gonopore. All Megalopsallus spp. have a mixed vestiture of weakly flattened, lanceolate, silvery or white setae and reclining simple setae, the length of the antennal segment 2 is usually longer than the head width; in most species the apex of the vesical strap is not bifurcate. Those species of Megalopsallus with apically bifurcate vesical straps (M. ellae Schuh and Schwartz, M. ephedrae Knight, M. froeschneri Schuh, and M. pallipes Knight) do not have the uniformly dark coloration found in Chlamyopsallus.

    Description:

    Male: Small, moderately elongate, moderately flattened, macropterous; range total length 2.74–2.90, range apex clypeus-cuneal fracture 1.75–2.00. COLORATION (fig. 1): dorsum entirely black; antennae, labium, except segment 4, and legs pale yellow; antennal segments 3 and 4 dusky yellow; labial segment 4, apical half of third tarsal segment and claws black; tibiae with minute black spots at bases of spines; hemelytral membrane strongly infuscate. SURFACE AND VESTITURE: Impunctate, smooth, highly polished, and shining; vestiture composed long, suberect, black setae (fig. 5G,H). STRUCTURE: Head transverse, conforming to anterior margin of pronotum (fig. 5A,B); posterior margin of vertex with low, broadly rounded carina, width of carina broadest medially; anteocular portion of head slightly longer than eye width (fig. 5A,B), clypeus not visible from above; frons gently curved; eyes small, head projecting below eyes by one-quarter head height, ventral margin of antennal fossa slightly below ventral margin of eye; length of antennal segment 2 less than width of head, length roughly equal to width of vertex plus width of one eye; diameter of segment 2 widest subapically, equal to diameter of segment 1; diameter of segments 3 and 4 narrower than that of segment 2; labium short, reaching to middle of middle coxae; pronotum trapeziform in dorsal view; mesothoracic spiracle and metathoracic scent gland as in figure 5C; hemelytra margins subparallel, cuneal fracture moderately incised, cuneus slightly deflected at fracture; anterior edge of coxae with black bristles, tibial spines long, black; claws of moderate size, gently curved at point level with apex of pulvillus; pulvillus large, adnate to ventral margin for almost entire length; parempodia setiform (fig. 5D,F); hind femoral trichobothria as in figure 5E; abdomen small, tapering toward relatively small genital segment, the latter occupying about one-third length of abdomen and reaching to middle of cuneus in lateral view. GENITALIA: Vesica (fig. 2) slender, delicate, composed of single, sinuously curving strap with bifurcate apex, region distal to secondary gonopore short, less than one-half length of secondary gonopore; secondary gonopore situated subapically on strap; secondary gonopore relatively large, with aperture sculpturing extending distally and base with short, nonspinose sclerite; phallotheca without distinctive features; left paramere conventionally phyline; right paramere small, ovate.

    Female: Body strongly ovate; macropterous with apex of abdomen reaching to apex of membrane in lateral view; coloration and vestiture similar to male; antennal segment 2 weakly sexually dimorphic, more slender and more strongly tapered toward base than in male.

    Etymology:

    Derived from a combination of the generic names Chlamydatus and Megalopsallus to acknowledge the similarity of habitus in the new genus to these more diverse and more widely distributed phyline taxa. Gender masculine.

    Discussion:

    As noted in the generic diagnosis Chlamyopsallus shares features with both Chlamydatus and Megalopsallus. Placing C. lycii in either one of those genera would broaden those diagnoses to the point of making them meaningless. Chlamyopsallus lacks the scalelike setae found in taxa of similar general appearance, for example, M. humeralis, and has suberect, black bristlelike setae not found in any species of Chlamydatus. Also as noted in the proceeding diagnosis of Chlamyopsallus, the vesica when examined carefully are distinct from the other two genera.

    Discussion:

    PSEUDOPSALLUS VAN DUZEE

  • Pseudopsallus Van Duzee, 1916b: 224 (n.gen.).

  • Revised Diagnosis:

    Stonedahl and Schwartz (1986, 1988) distinguished the genus from other Orthotylini based on the dorsal vestiture and male genitalic structure. The inclusion of greggii and tiquiliae in Pseudopsallus requires the following modifications to the generic diagnosis: tergal processes sometimes absent from anterodorsal margin of genital aperture (daleae and tiquiliae); basal sclerotized portion of the ductus seminis rarely without a pair of spiculae surrounding the left and right sides on the dorsal surface (tiquiliae); and right ventral spicula of the vesica rarely minute (greggii).

    Discussion:

    A medial interior flange and associated troughlike surface ventral to the flange of the right paramere is shared by species of Pseudopsallus and Presidomiris Stonedahl and Schwartz, 1988 (see Stonedahl and Schwartz 1988: 17). However the gray general coloration with dark fuscous to black markings on the head and pronotum with dark suffusion on the hemelytra (fig. 1) will distinguish greggii and tiquiliae from species of Presidiomiris, which are consistently unmarked and have orange yellow to yellow green overall coloration. The small body size and strongly produced anteocular portion of the head of the two new species are unique for Pseudopsallus, but the prepoderance of characters, especially the body coloration and overall features of the male genitalia, are persuasive enough to place them in the genus.

    The new species are generally similar to P. angularis (Uhler, 1894) and P. daleae (Knight, 1968) in the pale gray to pale brown overall coloration with distinct black to fuscous markings on the head, pronotum, venter, and legs (fig. 1). Although P. tulare Stonedahl and Schwartz, 1986 has the ground coloration pale greenish yellow, it has dark markings similar to the other four species. Portions of the male genitalia, specifically the prominent distal hump of the medial interior flange on the right paramere (fig. 7F– H) and deflexed left tergal process adjoining the genital aperture (fig. 7A, B) of greggii are similar to those of angularis (Stonedahl and Schwartz 1986: figs. 67, 68, 70, 71) and tulare. The absence of tergal processes (fig. 9A) and the small dorsal lobe of the left paramere (fig. 9E) in tiquiliae are also features seen in daleae (Stonedahl and Schwartz 1988: figs. 44, 47, 48).

    The scalelike setae of greggii (fig. 6C) and tiquiliae (fig. 8C) are similar in structure to those of the other species of Pseudopsallus (Stonedahl and Schwartz 1986: figs. 11–25, 1988: fig. 34A–C). All members of the genus have scalelike setae that are strongly flattened, moderately to broadly lanceolate, apically truncate or acuminate, and with converging or parallel ridges. Such setae were defined as type 2 by Stonedahl and Schwartz (1986).

    The pretarsus of the new species have strongly curved claws that are distinctly broadened basally, small pulvilli, and typically orthotyline lamellate and apically convergent parempodia (figs. 6D, 8D). The structure of the mesothoracic spiracle and metepisternal scent efferent system in the new species (figs. 6E, 8E) are unremarkable except for the relatively reduced evaporative area of the mesothoracic spiracle when compared with other North American Orthotylini (e.g., Schwartz and Scudder 2003: figs. 4E, 6D, 9C, 11B, 13B).

    The incorporation of greggii and tiquiliae into the cladistically derived phylogeny presented in Stonedahl and Schwartz (1986, 1988) is beyond the scope of this present paper, which is intended only to provide documentation for newly discovered taxa.

    The inclusion of two more taxa raises the number of species in Pseudopsallus to 25. In the key to Pseudopsallus species by Stonedahl and Schwartz (1986), greggii and tiquiliae will key to couplet 3 with angularis as well as daleae and tulare (see Stonedahl and Schwartz 1988: 15). The following addition to that key will distinguish these five species:

    1.  1. Clypeus entirely black, sometimes female with bilaterally paired and medial fuscous stripes; anteocular portion of head strongly produced (figs. 6A, B, 8A, B); body size less than 3.80

    2. — Clypeus entirely pale or with pale ground color and bilaterally paired and medial fuscous to black stripes; anteocular portion of head short or moderately produced (similar to Stonedahl and Schwartz 1986: figs. 5, 6, 8); body size greater than 4.00

    3.  2. Antennal segment 1 black; male without tergal processes on dorsal aperture of genital segment

    4. — Antennal segment 1 pale with a black basal annulus; male with tergal process on left dorsal margin of genital segment aperture

    5.  3. Dark marking on head limited to small bilateral pair on vertex near eyes; dorsal vestiture with pale simple setae; male without tergal processes on dorsal aperture of genital segment

    6. — Dark marking on head extensive, with bilateral stripes or blotches on frons, vertex, maxillary plate, and clypeus; dorsal vestiture with black simple setae

    7.  4. Body length 4.66–5.03♂, 5.02–5.60♀; pale greenish yellow general coloration with limited infuscation on pronotal disk and hemelytra; anteocular portion of head produced; male genitalia distinctive (see Stonedahl and Schwartz 1988: 15, 16, figs. 50–55)

    8. — Body length 5.30–6.30♂, 5.50–6.20♀; brownish yellow or brownish gray general coloration with extensive infuscation on hemelytra; anteocular portion of head not produced; male genitalia distinctive (see Stonedahl and Schwartz 1986: 13, figs. 65– 71)

    The new species utilize host plants of the genus Tiquilia Persoon [∼Coldenia Linnaeus] or coldenia and crinklemat and are thus the only members of Pseudopsallus to be associated with the Boraginaceae. The known hosts of the other species of this endemic North American plant bug genus are from the Asteraceae (eight spp.), Fabaceae (one sp.), Hydrophyllaceae (two spp.), Lamiaceae (one sp.), Nyctaginaceae (two spp.), and Onagraceae (six spp.) (Stonedahl and Schwartz 1986, 1988).

    Pseudopsallus tiquiliae, new species Figures 1, 8, 9

    Holotype:

    Male: “USA: California: Imperial Co., 5.4 mi NW Ocotillo on rt S2, April 23, 1980, Schwartz & Russell, Tiquilia palmeri (A. Gray) A. Rich[ards.] (Boraginaceae).” Deposited in the American Museum of Natural History.

    Diagnosis:

    Distinguished from greggii, the only other small species of Pseudopsallus with a strongly produced anteocular portion of the head, by the black antennal segment 1, small dark fuscous spots on the dorsoapical surface of the femora, smaller fuscous labium, more narrow vertex, and shorter anteocular portion of the head (measurement comparison in preceding species treatment).

    Description:

    Male: Small, parallel-sided. MEASUREMENTS: Total length 3.38 (2.90–3.85), length apex clypeus-cuneal fracture 2.31 (2.10–2.60), maximum width across hemelytra 1.20 (1.10–1.34); head width 0.65 (0.59–0.69), vertex width 0.32 (0.30–0.33), anteocular length 0.28 (0.26– 0.30), eye width 0.15 (0.13–0.18), eye height 0.31 (0.28–0.33); antennal length segment 1: 0.22 (0.21–0.23), 2: 0.99 (0.86–1.14), 3: 0.72 (0.63–0.83), 4: 0.28 (0.24–0.35); labium length 1.68 (1.50–1.85), reaching middle of genital segment; pronotum width 1.00 (0.86– 1.08), pronotum length 0.46 (0.41–0.50).
