Diagnosis. Aulacophora opacipennis is similar to A. apicipes with yellowish brown body, and black and opaque elytron but A. opacipennis is easily separated from A. apicipes by the yellowish brown legs and black elytron (black tibia and tarsi, yellow apical margin of elytron in A. apicipes).
Males. Length 6.2 mm, width 3.1 mm. General color (Figs 80–81) yellowish brown except elytron black and opaque. Antenna (Fig. 100) filiform, antennomere I not enlarged, apico-lateral angles of antennomeres III–IV produced anteriorly; ratio of length of antennomeres III to XI about 1.0: 1.2: 1.1: 1.1: 1.1: 1.1: 1.1: 1.1: 1.5; ratio of length to width from antennomere III to XI about 2.7: 3.3: 2.7: 2.7: 2.9: 3.2: 3.5: 3.7: 5.4. Abdominal tergite forming notch (Fig. 106), weakly convex at middle; base weakly sclerotized. Median lobe of fifth abdominal ventrite rectangular, with median longitudinal ridge represented from middle extending beyong base, median longitudinal internal ridge well developed; disc depressed at apical area. Penis (Figs 102–103) wide, abruptly narrowed from apical 1/6 to apex, apex pointed, less widened at basal 2/5; curved in lateral view; tectum well sclerotized, apex pointed, abruptly widened at basal 1/3, lateral margin with triangular sclerite recurved at basal 1/3; endophallus with several stout setae scattered, and with one longitudinal sclerite, apex recurved and rounded, basally widened.
Females. Length 7.5–7.9 mm, width 3.9–4.3 mm. Similar to male, but antenna more slender (Fig. 101), and apico-lateral angles of antennomeres III–IV less produced anterior; ratio of length of antennomeres III to XI about 1.0: 1.0: 1.0: 1.0: 1.0: 0.9: 0.9: 0.9: 1.0; ratio of length to width from antennomere III to XI about 3.7: 3.8: 4.2: 4.2: 4.2: 4.2: 4.4: 4.2: 5.5. Apical margin of abdominal ventrite V truncate. Gonocoxae (Fig. 104) slender, apex of each gonocoxa with eight setae from apical 1/6 to apex; gonocoxae connected at middle, base widened. Ventrite VIII (Fig. 105) weakly sclerotized; apex narrow, apical margin a little emarginate at middle, surface with dense short setae inside and along apical margin, and with extremely long setae near apical margin; spiculum short. Spermathecal receptaculum (Fig. 107) a little swollen, hardly separated from pump; pump strongly curved; spermathecal duct short, stout, and strongly curved, shallowly projecting into receptaculum.
Host plant. Unknown.
Distribution. Endemic to Taiwan.
