Genus Drabescoides Kwon & Lee

Drabescoides Kwon & Lee, 1979: 53 , figs. 3 –6; Zhang & Webb, 1996: 14, figs. 208–217; Zhang, et al., 1997: 235 –245, fig. 1. Type species: Selenocephalus nuchalis ( Jacobi, 1943) .

Description. Body color. Body orange to brown, head and thorax marked with black or brown spots or transverse lines, frontoclypeus with a row of regular brown spots on lateral margins.

External morphology. Body length (including tegmina): ♂, 6.8–7.6 mm.

Head including eyes wider than pronotum, front margin rounded anteriorly in dorsal view, midlength nearly as long as next to eyes. Face with laterofrontal sutures extended to ocelli; ocelli situated on margin of vertex with 3 times own diameter from ocellus to adjacent eye; antennae long, nearly equal to half body length or more; clypellus broader apically than basally. Forewing with five apical cells and three anteapical cells, first anteapical cell open basally, second and third ones closed; with 1–3 cross veins between claval veins. Front femur with short and stout anterior ventral (AV1) setae, intercalary row (IC) linear with fine setae, anteromedian setal (AM1) row with one stout seta. Protibia with 4 + 4 or more setae. Hind femur with apical setal formula 2 + 2 + 1 and first tarsomere with 2 apical setae and four platellae.

Male genitalia. Pygofer lobe with 2–5 processes and few macrosetae ventroposteriorly. Valve semi-elliptical or triangular. Subgenital plate about triangular, without marginal setae. Style broad at base and narrowed on apex. Aedeagal shaft broad, flat, and tapered to upturned apex in lateral view, and with pair of basal processes on lateral margins.

Distribution. Palearctic and Oriental region ( China, Korea and Russia) ( Fig. 7 ).

Remarks. Species of Drabescoides are extremely similar to each other in body coloration and appearance, however the unique male genitalia of each species provides good characters for identification. Drabescoides differs from other taxa of Paraboloponina by the following combined characteristics: male pygofer with two or more processes; aedeagal shaft broad and flat, tapered to rounded apex and with pair of basal processes on aedeagus.
