3. Drabescus bicornis View in CoL n. sp. ( Figs 1 View FIGURE 1. 3 C, 4)
Body length (incl. tegmen): 3 6.2 mm.
Body yellowish brown, forewing brown, face yellow, pronotum with dense yellowish spots; scutellum with two yellowish triangular marks along each side. Head slightly wider than pronotum; vertex triangularly produced, midlength longer than length next to eyes; ocelli on margin, separated from corresponding eye; antennae short, situated above midlength of eye in facial view, antennal ledge strong, laterofrontal suture reaching corresponding ocellus; clypeus expanded apically, epistomal suture distinct; pronotum with lateral margin short, carinate, hind margin concave medially; forewing, hyaline, veins distinct, with obscure net-like lines, appendix broad; fore tibia rounded dorsally; hind femur with setal formula 2+1.
Male genitalia with pygofer triangular in lateral view, broad at base and narrowed to apex, with several macrosetae posteriorly; valve short; subgenital plate broad basally over short distance, tapered to digitate apex, with fine setae laterobasally and apically; style with apical process long and blunt, with small beakshaped process laterally at apex, lateral lobe absent; connective short; aedeagus robust, shaft curved strongly dorsally, preatrium with pair of long straight processes directed posteriorly, the latter longer than shaft; connective attached to aedeagus near base of processes.
Holotype: 3 (MNL), Papua New Guinea, Aiyura Exp. Sta, III-1945, coll. B. O. Connor & J. L. Froggatt.
Remarks: This species is very similar to D. evansi in the male genitalia but can be distinguished from the latter in having the style without a lateral lobe and with the apical process long and blunt, with a small beakshaped process laterally at apex.
Etymology: This species is named for the paired aedeagal processes.
