Aphelocheirus (s.str.) sp. “B”

(Fig. 14)

Material examined. 1 female (brachypterous; paralectotypes of A. inops ): “Annam\ Laos ”, “inops H.\ det. Horváth ”, “TYPUS”, “ PARALECTOTYPUS \ Aphelochirus \ inops Horváth, 1918 \ labelled Zettel & Tran 2008”, “ Aphelocheirus \ sp. B\ det. Zettel & Tran 2008” ( HNHM) .

Notes on morphology. Size. Body length 7.9 mm. Body width 5.1 mm. Pronotum width 3.9 mm. Colour of dorsum dark brown, but head yellow with black triangle at base and mesoscutellum yellowish. Head much shorter than long (0.85 times). Rostrum reaching mesocoxa. Medial propleural process with rounded apex. Mesosternum with raised, rounded medial hump. Hemielytra coarsely granulate, posteriorly almost reaching posterior margin of tergite 2, medially with narrow gap (ca. 0.1 times hemielytron width). Each hemielytron wider than long (ca. 1.3 times), laterally with very short triangular embolar process (process width 0.07 times total hemielytron width). Sternites without recognizable peg-like setae. Subgenital plate (Fig. 14) almost trapezoidal with small apical lobe; sides weakly concave and with narrow tufts of comparatively short, curved setae at about mid-length; with subapical transverse row of setae directed straight caudad.

Discussion. This single female has some similarities to A. gularis , but it is longer and has an elongate subgenital plate with relatively shorter lateral setae (comp. Figs 12 and 14). The absence of peg-like setae on abdominal sternites would place it in the A. minor species group ( ZETTEL et al. 2008), but the venter is almost polished, so it seems possible that all setae (and their insertions) are abraded. The female is very different from that of A. lahu POLHEMUS & POLHEMUS, 1989 , the only species of the A. minor group described from Southeast Asia; and it cannot be assigned to any described species so far.
