“We have little doubt it is rightly referred to this species,” wrote Godman and Salvin (1893: 262) about their only Panamanian specimen, a female from Calobre, in order to treat the South American Jemadia hewitsonii (Mabille, 1878) in their “Biologia Centrali-Americana. Insecta. Lepidoptera—Rhopalocera.” Half a century later, Evans included her in a type series of the newly described subspecies J. hewitsonii pater Evans, 1951, which after 50 more years Burns elevated to species status. This female is neither J. hewitsonii nor J. pater, but a new species, possibly closest to South American Jemadia ovid Evans, 1951, new status. The new Central American Jemadia, repeatedly reared in the Caribbean rain forest of Costa Rica's Area de Conservación Guanacaste, is described here as Jemadia suekentonmiller Grishin, sp. nov.; and its facies, genitalia, and DNA barcodes are closely compared with those of various congeners. The twice-misplaced female is a paratype of J. suekentonmiller and is still the only known specimen from Panama.
Despite much work and some dedicated collecting, the Central American Hesperiidae fauna is still rich in surprises. In Nicaragua and Costa Rica, many phylogenetic groups that originated in South America currently appear to be at their northern distribution limits. Central American populations in some groups have become species that are often less common than their South American sister species and so morphologically similar to them (at least in facies) as to be cryptic (e.g., Grishin et al. 2013a).
Large series of specimens are desirable to study intraspecific variation and document interspecific differences. Abundant material from a long-term comprehensive inventory of the non-leaf miner species of Lepidoptera of Area de Conservación Guanacaste (ACG) in northwestern Costa Rica (Janzen et al. 2009, Janzen and Hallwachs 2011) is extraordinarily useful in this taxonomic effort. Because most of this material has been reared from wild-caught caterpillars, knowledge of their traits, foodplants, ecology, etc., greatly augments the usual data from adult morphology. Moreover, short sequences (ca. 654 bp) of mitochondial DNA coding for the C-terminal segment of cytochrome c oxidase subunit 1 (COI), and dubbed DNA barcodes, are routinely obtained for many specimens, adding molecular characters to those of morphology and biology. These DNA barcodes have been remarkable flags, both indicating possible new species and identifying recognized species (Hebert et al. 2004, Burns and Janzen 2005, Janzen et al. 2009, 2011, 2012, Burns et al. 2010, 2008, 2013, Grishin et al. 2013a, b).
While barcoding and more advanced DNA-based technologies are beginning to catch on in other areas of the Neotropics (Ratnasingham and Hebert 2007), traditional morphological comparisons are an integral part of species discovery and recognition of new ACG taxa in contrast to their closest relatives farther south. For instance, diligent and insightful analysis of facies and genitalia performed by Burns (Burns and Janzen 2001) detected a possible undescribed species of Jemadia E. Watson, 1893 on the basis of just three reared specimens, only one of which was male. Comparison of over a dozen males and half a dozen females of this species available today supports Burns's conclusions. Moreover, comparison with the COI barcodes of other Jemadia species, many of which are South American and are from the same Jemadia hewitsonii species group, further strengthen the species-level status of this new taxon and place it further away from other J. hewitsonii-like species. Here, we formally describe this species and discuss its differences from other J. hewitsonii group taxa, both in facies and in male genitalia.
It should be noted that taxonomy of J. hewitsonii species group is currently uncertain. Further work on this group (and all Pyrrhopygini Mabille, 1877) is in progress and will soon be published by O. H. H. Mielke, E. Brockmann, and C. Mielke (pers. comm.). The purpose of this study is to describe a new species in the group and to show how to distinguish this new species from other taxa. Fortunately, the identity of taxa closest to the new species is quite clear. However, for completeness of comparison, we also illustrate facies and male genitalia of other distinct phenotypes in the J. hewitsonii group. Some of these taxa remain unnamed until the Mielke, Brockmann, and Mielke publication.
Materials and Methods
Adult specimens used in this study are from the following collections: National Museum of Natural History, Smithsonian Institution, Washington, DC, USA (USNM); Natural History Museum, London, UK (BMNH); Museum für Naturkunde, Berlin, Germany (ZMHB); and American Museum of Natural History, New York, NY, USA (AMNH). All specimens reared from wild-caught caterpillars by the ACG inventory are so indicated with a specimen voucher code in the format yy-SRNP-x…, where “yy” are the last two digits of a year and “x…” is the serial number (1 to 5 digits long) of a specimen recorded for that year, e.g., 5289 or 22467. (A 6-digit code means that the adult specimen was wild-caught instead of reared.) This SRNP code can be sought on the inventory web site (Janzen and Hallwachs 2013) and soon, in general internet search engines. When they are reared, adults are on average slightly smaller than the wild-caught ones that usually populate museums.
For genitalia dissection, NVG used the following method (Robbins 1991): the abdomen was broken off, soaked for 40 minutes (or until ready) in 10% KOH at 60°C (or overnight at room temperature), dissected, and subsequently stored in a small glycerol-filled vial on the pin under the specimen. Genitalia and wing venation terminology follows Steinhauser (1981). Length measurements are in metric units and were made from photographs of specimens taken with a scale and magnified on a computer screen. Photographs of specimens and dry genitalia were taken by NVG with Nikon D200 and Nikon D800 cameras through a 105 mm f/2.8G AF-S VR Micro-Nikkor lens; dissected genitalia were photographed in glycerol with the Nikon D200 camera without the lens and through microscopes at 2× and 5× magnifications. Images were assembled and edited in Photoshop CS5.1. Genitalia photographs were taken in several focus slices and stacked in Photoshop to increase depth of field. DNA sequences were downloaded from GenBank < http://genbank.gov/> or BOLD < http://www.boldsystems.org/>, aligned by hand since they matched throughout their length without insertions or deletions, and analyzed using the Phylogeny.fr server at http://www.phylogeny.fr/ with default parameters (Dereeper et al. 2008). Many of these sequences have been reported in Janzen et al. (2011) and photos of specimens are available from the Area de Conservación Guanacaste (ACG) on-line database (Janzen and Hallwachs 2013) and BOLD database (Ratnasingham and Hebert 2007) to confirm or suggest identifications.
Results and Discussion
Evans characterized J. hewitsonii by white-spotted patagia and the presence of a short discal “blue band” on the dorsal hindwing “from vein 7 [=Rs] to vein 3 [=Cu1], placed above 2 oblique basal streaks” (Evans 1951: 52–53). This blue band, shaped more like a ray (indicated by arrows in Fig. 45), runs between the splits of two vein pairs: Rs with M1 and M3 with Cu1 (yellow arrows in Fig. 45b), in most taxa spilling into the base of the cell M3–Cu1 (pink arrow in Fig. 45c) and possibly into the base of the cell Rs–M1 (upper pink arrow in Fig. 45d). Evans (1951: 53) partitioned J. hewitsonii into five subspecies. He used the widths of the discal white band and a doublet of postdiscal spots on the forewing and the form and appearance of the submarginal band on the dorsal hindwing as the main characters to differentiate among the subspecies. The first and the northernmost subspecies, recorded from Panama, Colombia, and Venezuela, Burns later recognized as a distinct species, J. pater Evans, 1951, owing to the differences in genitalic valvae between it and other taxa (Burns and Janzen 2001). In a series of 73 type specimens of J. pater in the BMNH collection curated by Evans, only one, a female from Panama, has a shorter blue ray (running only from vein 6 [=M1] to vein 4 [=M3]) without either of the blue spots at the bases of M3–Cu1 and Rs–M1 cells. In all other J. pater specimens we examined, the blue ray intrudes at least into the cell M3–Cu1. However, 19 ACG specimens of Jemadia lack the longer blue ray characteristic of J. pater; instead, this ray is invariably short and limited to the spaces between veins 6 and 4 and not between 7 and 3. Therefore, these specimens, called “Jemadia Burns01″ in Janzen et al. (2011), do not key out to J. hewitsonii of Evans (1951). They are described here (with the aforementioned female from Panama) as a new species proposed previously without a formal scientific name by Burns and Janzen (2001) and differing from all other J. hewitsonii group taxa not only by wing patterns but also by male genitalia and, where known, DNA barcodes (over 5% difference).

We also determined barcode sequences of 13 paratypes. Seven of them (voucher codes/GenBank accessions: 10-SRNP-103600/HM884525, 05-SRNP-31969/GU151442, 04-SRNP-32358/GU161555, 04-SRNP-30754/DQ292573, 03-SRNP-21823/DQ292574, 03-SRNP-21528/DQ292575, 01-SRNP-9029/DQ292569) are identical to that of the holotype (except that 01-SRNP-9029 has a single undetermined base pair (bp) “N” within its sequence and is lacking 102 bp from the 3′ end) and others show variation within a third of a percent: 1 bp difference (145 C, not T [numbering is from 1 to 658 for the holotype as a reference]) in five sequences (09-SRNP-30034/GU649882, 05-SRNP-31086/GU150502, 04-SRNP-56811/GU150503, 02-SRNP-13059/DQ292570, 00-SRNP-4482/DQ292571), and 2 bp difference (145 C, not T and 592 T, not A) in one (96-SRNP-12846/DQ292572). Several of these sequences lack some segments at the termini. All of these 14 sequences appear monophyletic on all the trees we have seen or built, and the closest available sequence to them is that of J. pater, different by 23 bp, which is over 5% (Fig. 50). Additional (and updated) information and neighbor-joining trees can be retrieved by searching the BOLD database (Ratnasingham and Hebert 2007) with the holotype sequence at < http://www.boldsystems.org/index.php/IDS_OpenIdEngine>.

Type locality: COSTA RICA: Area de Conservación Guanacaste, Guanacaste Province, Sector Pitilla, site Sendero Cuestona, GPS: 10.99455 -85.41461, elevation 640 m.
Etymology: Burns and Janzen (2001) wrote: “… the northernmost member of the J. hewitsonii species complex … is … in the rainforest of the ACG … and … more adults are desired before formal description of this apparent differentiate.” The adults are now available, and this spectacular butterfly is named in honor of Susan Miller and Kenton Miller (RIP), in recognition of their 48 years of intense advocacy, planning, legitimizing, and mentoring the national parks of the world, and, specifically, recommending and planning the founding of Parque Nacional Santa Rosa in 1971 (today Sector Santa Rosa), the initial seed of Area de Conservacion Guanacaste (ACG), and mentoring and inspiring Alvaro Ugalde and Mario Boza to found the national park system of Costa Rica. Without their efforts, all known ACG forest habitat for this butterfly would long ago have been logged and agroscaped.
Distribution and phenology: Currently, this rain forest species is known from Costa Rica (Guanacaste, Alajuela and Cartago provinces) and Panama (Veraguas province), and has been reared in Costa Rica to eclose in February, March, April and August, September, October (Janzen and Hallwachs 2013), and two freeflying adults have been collected in March and April. The reasons for peaks and troughs in its phenology are unclear.
Diagnosis: This species belongs to Jemadia, because it possesses all the characters of the genus as given in the Evans identification key (1951: 3–4) and is particularly similar to other J. hewitsonii group taxa (all treated by Evans as subspecies). COI barcode sequences have been obtained for most species of Jemadia, including its type species, Jemadia hospita (Butler, 1877) (Fig. 50). The difference between the DNA barcodes of J. suekentonmiller and J. hospita is close to 10%, and is about the same as differences in many other Jemadia species pairs, e. g., J. hospita and J. fallax (Mabille, 1878) (Fig. 50). Although DNA sequence information about Jemadia is still very scarce, it is significant that the tree shown in Fig. 50 agrees very well with morphological evidence (Figs. 1–48, 51 and Warren et al. (2013) with photographs of other species), and that there is no indication of introgression or hybridization between species. Reliable groupings in the tree agree with the structure of Evans's (1951) identification key, e.g., all J. hewitsonii group taxa form a monophyletic group. Moreover, each of two pairs of species that are next to each other in his key, i.e., J. hospita (in which Evans included J. pseudognetus (Mabille, 1878) as a subspecies) plus J. sosia (Mabille, 1878) and J. menechmus (Mabille, 1878) plus J. scomber H. Druce, 1908, comprises sister taxa in the tree (Fig. 50).
The new species belongs to the Jemadia hewitsonii group by phenotype and by its position in the DNA barcode NJ tree. Taxa in this group can be distinguished from other Jemadia by the white-spotted collar and by the dorsal pattern of the hindwing, which consists of: (a) two pale streaks along veins Cu2 and 2A from the base to at least half of the wing, the first streak paler and the second one bluer; (b) short discal blue ray constrained between veins Rs and Cu1 and directed from the split of veins Rs and M1 towards the split of veins M3 and Cu1; (c) postdiscal blue band approximately following the contour of hindwing outer margin. In other Jemadia species groups, either the pale streaks along veins Cu2 and 2A are absent or short and discal ray is very long, reaching 2A vein; or the discal ray is absent (Fig. 45).
The new species is distinguished from all other taxa in the J. hewitsonii group by the combination of the following characters (the first two are likely diagnostic for facies): (1) discal blue ray on dorsal hindwing is short, only between M1 and M3 veins, blue scales do not invade bases of cells Rs-M1 and M3-Cu1 (Fig. 45a); (2) discal white band on forewing is rather broad, 2.5–4.5 times longer than width (Figs. 1–14); (3) postdiscal blue band on dorsal hindwing is medium to broad, developed in all cells between veins Rs and 3A (Figs. 1–14); (4) cucullus distal end is at about the same height as proximal end (Figs. 46a, i, 47a); (5) cucullus dorsal margin is only slightly concave, more finely dentate; (6) cucullus ventral margin distally bends dorsad almost at a right angle and at the distal end deviates only slightly from a straight vertical line, thus cucullus appears most rectangular of all J. hewitsonii group species; (7) dorsolateral process (one on each side) off the distal end of tegumen is long, finger-like; (8) phallobase is short, about half of the penis length; (9) dorsal margin of sacculus near the apical tooth is dentate and irregular, not smooth and ending in a single prominent tooth; (10) saccus slightly bulbous at the apex (for genitalia characters see Figs. 46, 47a). These characters are illustrated in Fig. 51.
Interestingly, J. suekentonmiller shares most of these characters (all except 2, 5, 6 & 10) with Jemadia ovid Evans, 1951, new status, described as a subspecies of J. hewitsonii (Fig. 51). Both J. suekentonmiller and J. ovid have a short discal blue ray (character 1, Figs. 46a, b, yellow arrows) and well-defined postdiscal blue bands (character 3, Figs. 46a, b) on dorsal hindwing, cucullus distal end the same height as proximal end (character 4, Figs. 46a, g); long tegumen processes (character 7, Figs. 46a, g, pointed to by a brown arrow); short phallobase (character 8, Figs. 46a, g, measurements indicated by green marks and ratios shown in green numbers); and several teeth at the dorsal margin of sacculus (character 9, Figs. 46a, g, shown as insets “z”). Preliminary analysis of female genitalia (Fig. 48) shows that both the new species and J. ovid are characterized by narrower lamella antevaginalis near the antrum than that of both J. pater and J. cf. hewitsonii. While we did not obtain DNA sequences of J. ovid, we suspect that these extensive phenotypic similarities indicate that J. suekentonmiller is its Central American sister. Because of these similarities with the new species, as thus different from all other J. hewitsonii group taxa (J. pater and J. ortizi included), we treat J. ovid as a distinct species rather than a subspecies, in-line with the conclusions of Burns and Janzen (2001) who wrote: “Consideration of the color-pattern characters …, coupled with comparison of … genitalia …, suggests that several closely related species, rather than subspecies, comprise a Jemadia hewitsonii species complex.”
The new species can be distinguished from J. ovid by its wider forewing discal band, whose width in J. ovid is less than a quarter of its length (character 2, Figs 1–14 vs. 23–28, ovid also has a very narrow, mostly streak-like, in males, postdiscal doublet of spots, Fig. 51); narrower postdiscal blue band on hindwings and this band is the broadest in J. ovid of all J. hewitsonii group taxa; less concave and finer dentate dorsal margin of cucullus, which is deeply concave and distally coarser dentate in J. ovid (character 5, Figs. 47a, g, h, i); cucullus being more rectangular in shape rather than more rounded distally in J. ovid (character 6, Figs. 47a, g, h, i); saccus looking more bulbous apically, but appearing narrower in J. ovid (character 10, Figs. 47a, g, insets “s”).
The next closest species is J. pater, which is probably sympatric with J. suekentonmiller in Panama (Fig. 51). These two species share the width of the discal forewing white band (not as narrow as in J. ovid, character 2, Figs. 1–14 vs. 15–20); cucullus ends being at about the same height (character 4); and slightly bulbous saccus (character 10, Figs. 46a, b, insets “s”). However, seven remaining characters differ between them. Notably, J. pater has longer discal blue ray on dorsal hindwing (between veins Rs and Cu1) and narrower postdiscal blue band; more concave and coarsely dentate dorsal margin of cucullus; more rounded distal end of cucullus, almost turning anteriad at the distal end; shorter process on tegumen; longer phallobase; and smooth dorsal margin of sacculus (Figs. 15–20, 48b–e). Recently described J. ortizi Orellana,  is very similar to J. pater (Fig. 51), but is characterized by darker palpi and foretarsi (Fig. 22), which are white in J. suekentonmiller; even more concave than in J. pater distal margin of cucullus, whose distal end is higher than the proximal end (Fig. 48f); and saccus that is even more bulbous at its apex (Fig. 48f inset “s”). Therefore J. ortizi appears to be even more distinct from the new species than is J. pater.
Other taxa in the J. hewitsonii group and unnamed phenotypes, differ by a larger number of characters, both in facies and genitalia, and are illustrated in Figs. 29–44, 45c–d, 47j–m, 48i–n, 50 (part), 51 (part) for comparison. Their taxonomy remains uncertain to us, but interesting differences in genitalia are observed, including, among others, the shape of cucullus and proportions of penis (compare Figs. 47j, k, l, and m), and sacculus dorsal margin (pointed at with pink arrow in Fig. 47). Interestingly, the proportions of penis (with shorter phallobase) are similar to those of J. suekentonmiller in some of these taxa (e.g., Fig. 47l). Further work on this group is in progress (O. Mielke, E. Brockmann, and C. Mielke, pers. comm.).
Immatures and foodplants (Fig. 49): In ACG, and probably elsewhere, J. suekentonmiller is highly hostspecific, with all 68 wild-caught caterpillars having been found feeding on mature foliage of ACG rain forest Casearia arborea (Salicaceae). While these caterpillars were 1–4 m above the ground, there may be some in higher foliage not inspected for caterpillars. All C. arborea inspected for these caterpillars were growing on road-forest or abandoned pasture-forest edges, a microhabitat that is a facsimile of the margins of natural disturbance sites. While ACG is rich in species of Casearia, thousands of caterpillar capture records indicate that J. suekentonmiller eats only this one, and does this almost entirely in one band of intermediate elevation rain forest about 25 km long and 1–2 km wide, from the area of Estacion Biologica Pitilla in Sector Pitilla to Estacion Caribe in Sector Rincon Rain Forest (see Sector maps at http://www.acguanacaste.ac.cr/).
The first instar caterpillars are parasitized by an undescribed likely host-specific species of Ogmoelachertus Schauff, 2000 (Hymenoptera: Eulophidae), and the 2nd–4th instar caterpillars are parasitized by an undescribed likely host-specific species of Casinaria Holmgren, 1859 (Hymenoptera: Ichneumonidae). The last instar caterpillars are parasitized by an undescribed species of ACG rain forest Houghia Coquillett, 1897 (Diptera: Tachinidae) that specializes in attacking Pyrrhopygini.
The striking black and yellow ringed-to-dotted caterpillar color pattern (Fig. 49) places this hairy caterpillar among a large complex of similarly-colored mimics being described and analyzed elsewhere, in the same spirit as those with false eye spots (Janzen et al. 2010). The semi-hairy pupa ornamented with dark colors and fragmented white waxy overlay, standard for ACG Pyrrhopygini pupae, rather than the false eye spots commonly encountered decorating other ACG Hesperiidae pupae (e.g., Janzen et al. 2010), is probably mimicking a rotting and fungus-rich pupa, the consumption of which would be decidedly hazardous to the health of a foraging bird.
