Oides wangi sp. nov.

( Fig. 70 )

Types. Holotype ♂ (TCHU): “Palu / C. Celebes / XII.1987 [h, w]”; 1♂ (NMHB): “Drs. Sarasin / Celebes, Passo See [p, w]”.

Description. Length 9.3–9.4 mm, width 5.6–5.7 mm. General color yellowish; antenna yellowish brown but antennomeres IV–VIII and apical 1/4 of antennomere XI black. Antenna filiform in male ( Fig. 70A ), antennomeres IV longest, VI–IX slender, length ratios of antennomeres I–XI 1.0: 0.6: 1.5: 1.7: 1.5: 1.5: 1.5: 1.2: 1.2: 1.1: 1.5, length to width ratios of antennomeres I–IX 2.5: 1.9: 4.0: 4.6: 4.2: 3.9: 4.1: 3.9: 3.8: 3.6: 5.0. Pronotum transverse, 2.1x wider than long, disc convex but flattened as sides, without microreculation and but with sparsely coarse puncatures; baso- and apico-lateral angles boradly rounded; lateral margin rounded; apical margin slightly concave. Elytra elongate oval, widest at middle, 1.4x longer than wide; disc shining and with microreticulation and dense fine punctures, slightly convex, epipleurae near lateral margins, located 9/10 distance between suture and lateral margins, wide from base to basal 1/5, apically narrowed and abbreviated at apical 1/5; humeral calli prominent, with depression posterior to calli. Penis ( Figs 70B–70C ) wide, 6.4x longer than wide; parallel-sided, apically tapering from apical 1/3; tectum extremely elongate and apically reaching apex of penis; slightly curved in lateral view, wide from apical 1/3 to apex, apex anterior and posterior angular; ventral surface well sclerotized, internal sac without sclerites

Etymology. This new species is dedicated to Yu-Tang Wang, an active beetle collector in Taiwan, who collected valuable leaf beetles for this study including O. celebensis .

Diagnosis. Members of this new species are similar to O. dimidiaticornis in possessing yellow antennomeres IX–XI, but members of this new species are smaller and possess finer punctures on the elytra. In males, the aedeagi of O. takizawai sp. nov. are similar to those of O. bezdeki sp. nov., O. dimidiaticornis , and O. wangi sp. nov. in possessing an elongate tectum and apically narrowed penis. However, males of O. wangi sp. nov. are easily recognized by the broad apex of the penis.

Distribution. Indonesia: Sulawesi.
