Shang, Suqin, Zhang, Yalin & Shen, Lin, 2009, New species of the leafhopper genus Drabescus Stål (Hemiptera: Cicadellidae: Selenocephalinae) from Papua New Guinea, Zootaxa 2117, pp. 49-55 : 54-55

5. Drabescus brevispinus n. sp. ( Figs 1 E, 6)

Body length (incl. tegmen): 3 6.2–6.6 mm, Ƥ 6.8–7.2 mm.

Body and legs yellowish brown; pronotum with dark maculation; forewing brown with pale transverse band across the tips of clavus.

Drabescus brevispinus . A, pygofer in lateral view; B, valve and subgenital plate in dorsal view; C, aedeagus

and connective in lateral view; D, aedeagus and connective in dorsal view; E, style in ventral view.

Head wider than pronotum; vertex roundly produced, midlength longer than next to eye, transversely concave near fore margin, longitudinally striate; ocelli on margin, visible from above, approximately one-fifth own diameter from corresponding eye; antennae longer than half length of body, located above midlength of eye in facial view, antennal ledge weak; clypeus expanded apically; pronotum with lateral margin short, truncate on hind margin, carinate. Forewing hyaline. Fore tibia rounded dorsally; hind femur with apical setal formula 2+1.

Male genitalia with pygofer long and triangular in lateral view, with short process posteriorly; valve semicircular; subgenital plate broad basally and narrowly digitate apically, with fine setae along laterobasal margin; style with short robust spine-like apical process, lateral lobe indistinct, several short fine setae dorsally on subapical area; connective with stem similar in length to arms; aedeagal shaft curved dorsally, strong and short with long process basally on each side, the latter blade-like in lateral view and longer than the shaft.

Holotype: 3 (BMNH), Papua New Guinea, Mt Pauanda, 300m, on Ollaria, D. Hollis, B.M.1988-337. Paratypes: 13, 1Ƥ (SU), Papua New Guinea: Morobe Prov., Mt. Kaindi, 2360m, 31-VII-1981,Y. Komiya lgt.

Remarks: This species is similar to D. kaindii from Irian Jaya in the shape of style but differs from the latter in: (1) pygofer long and triangular in lateral view with short process posteriorly; (2) aedeagal shaft short and robust with long process basally on each side, the latter blade-like in lateral view.

Etymology: This species is named after short spine-like apophysis of style.
