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 : 50-51

1. Drabescus longispinus n. sp. ( Figs 1 A, 2)

Body length (incl. tegmen): 3 7.8–8.5 mm, Ƥ 8.0– 8.6 mm.

Body bright brown, forewing with dark maculation around apical cells and vein R1. Head slightly wider than pronotum; vertex triangularly produced anteriorly in dorsal view, midlength longer than next to eyes, width three times medial length; ocelli on margin, visible from above, separated from corresponding eye; antenna short, antennal ledge strong and oblique; clypeus expanded apically, epistomal suture obscure. Pronotum with lateral margin short, carinate, hind margin slightly concave. appendix broad. Fore tibia flattened dorsally; hind femur with apical setal formula 2+1.

Male genitalia with pygofer oblong, membranous at apex, with long process ventroposteriorly. Valve ligulate. Subgenital plate broad basally and narrowed to digitate apex, with many fine setae along laterobasal margin. Style with apical process robust, tapered to narrowly rounded apex, curved laterally; lateral lobe short. Connective long, length of arms longer than stem. Aedeagus with shaft simple, strongly curved cephalad, without processes; dorsal apodeme short.

Holotype: 3 (BMNH), Papua New Guinea: Madang District, Finisterre Mts, Damanti, 3550ft, 2-X-1964, coll. M. E. Bacchus. Paratypes: Papua New Guinea 43 (BMNH), same data as holotype except: 33, 2-11- X-1964; 13, Budemu Camp., Stn. No.52, 4000ft, 15-24-X-1964; 1Ƥ, Stn. No. 46, 2-11-X-1964; 1Ƥ, Araucaria Camp, 800m, III-1939; 1Ƥ, Rattan Camp, 1200m, 6-III-1939; 1Ƥ, Sigi Camp, 1500m, 24-II-1939, all coll. L. J. Toxopeus, Neth. Ind.-American New Guinea Exped., (MNL).

Remarks: This species is similar to D. feraminensis in external appearance but can be distinguished from this and other species by its long ventroposterior pygofer process.

Etymology: This species is named for its long pygofer processes.
