Diagnosis. See diagnosis of Aulacophora frontalis .

Males. Length 6.0– 6.6 mm, width 3.1–3.5 mm. General color ( Figs 108–108 ) yellowish brown except elytron black and shining. Vertical area of head with a strongly thickened transverse ridge on each side ( Fig. 112 ). Antenna ( Fig. 113 ) filiform, antennomere I a little swollen; III triangular, with semicircle groove at outer baso-lateral angles; IV and V extremely widened; V with longitudinal groove on lateral expansion, groove without setae; ratio of length of antennomeres III to XI about 1.0: 0.8: 0.9: 0.8: 0.9: 0.8: 0.9: 0.8: 1.0; ratio of length to width from antennomere III to XI about 1.6: 0.9: 1.2: 3.1: 3.5: 3.3: 3.4: 3.8: 4.8. Apex of abdominal tergite VIII weakly emarginate at middle ( Fig. 119 ), apical margin with several setae; base weakly sclerotized. Median lobe of fifth abdominal ventrite short and rectangular, disc flat and without longitudinal grooves, apical margin weakly emarginate at middle. Penis ( Figs 115–116 ) abruptly widened at apical 1/5, apex pointed; almost straight in lateral view but curved at apical 1/5; ventral surface depressed at middle of apical 1/5; tectum well sclerotized, apex widened; endophallus with dense, irregularly arranged setae, and with one longitudinal sclerite, apex rounded, basally widened and bifurcate.

Females. Length 6.8–7.7 mm, width 3.2–4.4 mm. Similar to male ( Fig. 110 ), but transverse ridge on vertical area absent; antenna filiform and not modified ( Fig. 114 ), ratio of length of antennomeres III to XI about 1.0: 0.9: 0.9: 0.9: 0.9: 0.9: 0.9: 0.9: 1.1; ratio of length to width from antennomere III to XI about 3.2: 3.2: 3.3: 3.0: 3.7: 3.6: 3.7: 3.5: 4.5. Apical margin of abdominal ventrite V not modified, rounded. Gonocoxae ( Fig. 117 ) slender, apex of each gonocoxa with eight or nine setae from apical 1/6 to apex; gonocoxae connected at middle, base widened. Ventrite VIII ( Fig. 118 ) weakly sclerotized; apex wide, apical margin a little emarginate at middle, surface with dense short setae along apical margin, and several long setae scattered at apical area; spiculum short. Spermathecal receptaculum ( Fig. 120 ) swollen, hardly separated from pump; pump strongly curved; spermathecal duct short, stout, shallowly projecting into receptaculum.

Host plants. Cucurbitaceae : Trichosanthes cucumeroides (Ser.) Maxim. ex Fr. & Sav. , and T. ovigera Bl. (present study).

Distribution. Burma, China, India, Indonesia, Malaysia, Taiwan, Vietnam.
