Aplosonyx duvivieri : Maulik 1936 : 618. Type specimen examined. ♀, syntype of Haplosonyx duvivieri Jacoby; Andrewes Bequest; B.M.1922-221; NHMUK 014596218. Additional specimen examined. ♂, China, Yunnan Province , Xishuangbanna, Menga; 29 May. 1958; Shuyong Wang leg.; IOZ(E)1566284. Diagnosis. This species can be distinguished from other Chinese species by yellow body, antennae, legs, labrum, and mandible black, and dense punctures on the elytra. This species differs from A. flavipennis in the head, pronotum, scutellum, and ventral surface of the thorax all being yellow. Redescription. Male. Length 8.9 mm, width 4.4 mm. Body yellow; antennae, legs, labrum, and mandibles black. Vertex covered with punctures. Interocular space 2.5 x as wide as transverse diameter of eye. Interantennal space 1.5 x as wide as transverse diameter of antennal socket. Frontal tubercles transverse, each separated by a deep furrow; antennae slender, extended to the middle of the elytra, 0.7 x as long as body; antennomeres 1-3 shiny; antennomeres 4-11 covered with pubescence, antennomere 2 shortest, antennomere 3 approximately 1.8 x as long as second; antennomere 4 longest, approximately 1.5 x as long as antennomeres 2 and 3 combined; antennomeres 5-10 gradually shortened, shorter than antennomere 4; antennomere 11 slightly longer than antennomere 10, pointed. Pronotum approximately 2 x as wide as long, lateral border margined, widest at posterior corners; disc with deep transverse furrow, covered with large punctures in furrow and with sparsely small punctures in other parts of pronotum. Scutellum triangular, covered with fine punctures. Elytra wider than pronotum, 0.7 x as long as body, 1.65 x as long as wide, with lateral margins straight and almost parallel, epipleura wide at anterior 1/4, posteriorly gradually narrowing towards apex, dorsal surface slightly convex, regularly covered with large deep punctures, the interstices of punctures narrower than diameter of punctures, and covered with small punctures in interstices.

Ventral surface of abdomen with five ventrites, ventrite 1 longest, ventrites 2-4 gradually shortened, apical ventrite slightly longer than ventrite 3, two subtriangular incisions. Figure 7. Aplosonyx duvivieri A-C habitus D-F aedeagus A, D dorsal views B, E ventral views C, F lateral views. Scale bars 0.5 mm ( D-F ); 1 mm ( A-C ). Aedeagus slender, parallel-sided, basally widened, narrowed in middle, apex pointed, in lateral view moderately bent. Female. Length 9.4 mm, width 4.7 mm. Antennae slightly thinner than in male, antennomere 2 shortest, antennomere 3 twice as long as second; antennomere 4 longest, 1.7 x as long as antennomeres 2 and 3 combined; apical sternite without incisions. Distribution. China: Yunnan; India.
