Punana sinica Liang sp. nov. (Hemiptera: Fulgoroidea: Delphacidae) is described and illustrated from Sichuan, southwest China. This represents the first record of the genus Punana Muir from China and the fifth known species of Punana. The new taxon extends the range of the genus Punana northward considerably, previously known only from southeast Asia and south India. A key for separation of the species of Punana is included.

The Delphacidae is the largest family of the Fulgoroidea, comprising more than 2000 described species in approximately 300 genera and six subfamilies worldwide (Asche 1985, Asche 1990). Members of the group are predominantly monocot-feeders and a few are major agricultural pests on grasses, such as rice, maize, and sugarcane (Wilson & O’Brien 1987, Wilson et al. 1994).

The delphacid fauna of China remains inadequately studied. The only comprehensive treatment of Chinese Delphacidae was that of Kuoh et al. (1983) in their Delphacidae volume of the Economic Insect Fauna of China, which deals with 123 species distributed in 47 genera, 2 tribes and 2 subfamilies. The number of described species likely represents only a small fraction of the actual diversity of the whole Chinese delphacid fauna considering the vast territory and various complex habitats of China.

The basal delphacid taxa, the Asiracinae and Vizcayinae, of Delphacidae in the Chinese fauna have received very little attention. To date, only six species in four genera from the Asiracinae (Asiracini, Ugyopini) and Vizcayinae are described or recorded from China, e.g., Asiraca choui (Yuan & Wang) (Shaanxi in central China), A. clavicornis (F.) (Xinjiang in northwest China), A. granulipennis (Kato) (Manchuria and Jinlin in northeastern China), and Ugyops zoe Fennah (Hainan Island in south China), all belonging in the Asiracinae, and Vizcaya longispinosa Liang (Yunnan in southwest China) and Neovizcaya sinica Liang (Yunnan in southwest China) of the subfamily Vizcayinae (Fennah 1956, Asche 1985, Asche 1990, Liang 1996, Liang 1998, Liang 2002).

The genus Punana was described by Muir (1913) for P. brunnea Muir from Borneo. Asche (1983) correctly separated Punana from Neopunana (8 species, the Caribbean) and Equasystatus (monotypic, Ecuador). Four species are currently included in the genus from Borneo, Philippines (Luzon, Negros), and south India (Muir 1913, Muir 1916, Distant 1916, Metcalf 1943, Asche 1983, Asche 1985). Asche (1985) placed Punana Muir in the tribe Ugyopini Fennah 1979 of the subfamily Asiracinae Motschulsky 1863. However, Emeljanov (1995) upgraded the Ugyopini to the subfamily rank and recognized three tribes in the Ugyopinae, e.g., Neopunanini Emeljanov 1995, Eodelphacini Emeljanov 1995 and Ugyopini. Punana Muir was placed by Emeljanov (1995) in the tribe Eodelphacini together with Eodelphax Kirkaldy 1901, Ostama Walker 1857, Paranda Melichar 1903, Melanesia Kirkaldy 1907, Livatiella Fennah 1956 and Prolivatis Emeljanov 1995. Eodelphacini is characterized by the distal part of the aedeagal shaft arched clockwise (from the base curved to the left); the presence of a row of teeth on the metatarsomere II, in which the marginal teeth are considerably longer than all others; the presence of the sinus on the hindwings opposite CuAP; forewings without postnodal transverse veins; the presence of a well-defined bend of the membrane when the wings are folded; and the intermediate carinae of mesonotum straight (Emeljanov 1995).

In the present paper the senior author describes a new species of the genus Punana Muir which was recently found in Sichuan, southwest China. The new species represents the first record of Punana in China, and its discovery has broadened our knowledge of the morphology and biogeography of the genus, as well as that of the primitive delphacid taxa in the Chinese fauna.

Descriptive Taxonomy

Punana Muir

PunanaMuir, 1913: 249. Type species: P. brunneaMuir, 1913, by original designation.

OnkelosDistant, 1916: 137. Type species: O. annulatusDistant, 1916, by original designation and monotypy. [Synonymized by Muir, 1919: 6.]

Head (Fig. 1, Fig. 3, Fig. 4) relatively broad, broadly roundly produced anteriorly. Vertex (Fig. 1, Fig. 3) very short, broader than long, disk foveate with a median carina (very faint in P. sinica sp. nov.) and two sublateral carinae which meet anteriorly with the extreme apical part incised posteriorly. Frons (Fig. 4) longer than broad, anterior margin truncate, convex medially, lateral marginal areas depressed, centrally finely carinate. Postclypeus (Fig. 4) more than half length of frons, convex medially, lateral marginal areas depressed, with median longitudinal carina. Anteclypeus (Fig. 4) very narrow and convex, with median carina. Rostrum long, reaching between hind trochanters, basal segment relatively long, apical segment relatively short, greater than 1/2 length of basal segment. Antennae (Fig. 1, Fig. 3, Fig. 4) moderately long, scape and pedicel with many sturdy bristles on surface, scape shorter than pedicel, with base distinctly narrow, strongly broadening toward apex, apex distinctly broad; pedicel cylindrical with base slightly flattened, with about 18 sensory fields. Pronotum (Fig. 1, Fig. 3) centrally slightly shorter than head, disk slightly sloping anteriorly, anterior lateral areas strongly sloping laterad, hind margin centrally slightly arched anteriorly, with median longitudinal carina. Mesonotum (Fig. 1, Fig. 3) longer than head and pronotum combined, with five longitudinal carinae on disk, extreme apex somewhat lobately produced. Legs moderately long, hind tibiae with three lateral spines on outer edge, five apical spines (the outer one largest and the middle one smallest) and a long apical conical mobile spur, metatarsomere I with 5 apical spines: four spines in a row and the fifth, middle spine, shifted proximally from the row, metatarsomere II with 3 apical spines (outer side 2, inner side 1). Forewings (Figs. 1 and 2) relatively narrow and elongate, about 3 times as long as broad, obliquely depressed laterally, apices broadly angulate, veins distinctly prominent and thickly covered with fuscous granules with long setae, a more or less continuous series of transverse veins before apical area. For forewing and hindwing venation see Asche (1985: fig. 204).

Male genitalia. See description of Punana sinica Liang sp. nov. below and Asche (1985: figs. 393, 441, 442).

Remarks. The above generic description was based on the specimen of the new species described below.

Punana is distinguished from other genera in the tribe Eodelphacini by the shape and length of the antennae, the shape of vertex and frons, the number of longitudinal carinae on mesonotum, the number of lateral spines on hind tibiae, the wing venation, and the minutiae of the male genitalia, as noted above.

Punana can be distinguished from Melanesia Kirkaldy (7 species, Borneo, Philippines and Fiji) and Paranda Melichar (monotypic, Sri Lanka) by the hind tibiae having 3 lateral spines (2 in Melanesia and Paranda) and the antennal pedicel distinctly short (distinctly elongate in Melanesia and Paranda). It can be distinguished from Eodelphax Kirkaldy (2 species, Sri Lanka) by the antennal scape and pedicel subcylindrical (both scape and pedicel compressed and scape obliquely triangular in Eodelphax). Punana differs from Prolivatis Emeljanov (monotypic, Vietnam) in the antennal pedicel short (relatively long in Prolivatis) and the male parameres relatively broad (very slender and narrow in Prolivatis). It differs from Ostama Walker [2 species, Borneo, Mentawi Island (East Indies)] in the antennae short (very elongate in Ostama), mesonotum with 5 carinae (3 in Ostama) and forewings with about 12 closed apical cells (about 15 in Ostama). Punana can be separated from Livatiella Fennah (2 species, eastern Caroline Island) by the forewing with Sc+R with two branches before subapical transverse nodal line (one branch in Livatiella) and the hindwing with the apical cell enclosed by M3 and M4 relatively long and large (very short and small in Livatiella).

Included species and distribution. Five species; P. annulata (Distant 1916) (south India), P. brunneaMuir, 1913 (Borneo), P. negrosensis Muir, 1916 [Philippines (Negros)], P. philippinaMuir, 1916 [Philippines (Luzon)], and P. sinica sp. nov. [southwest China (Sichuan) (new record)].

Etymology. This new species is named sinica after the Latin sinicus, adjective (“of China”), referring to its occurrence in China.

Distribution. Southwest China (Sichuan).

Remarks. This new species is externally similar to P. annulatus (Distant) from south India (Kodaikanal), which was illustrated by Distant (1916), Asche (1983), and Asche (1985), but differs from the latter in having the antennal pedicel subcylindrical and in the shape of the vertex, male genitalia and pygofer, as noted in the above key.
