Oides multimaculata Pic

( Figs 27G– 27I , 56 )

Oides multimaculata Pic, 1928: 29 ( Vietnam) ; Wilcox, 1971: 13 (catalogue); Kimoto, 1989: 39 (catalogue); Samoderzhenkov, 1992: 109 ( Vietnam); Yang et al., 2015: 97 ( China: Yunnan).

Types. Lectotype ♂ (MNHN): “ TONKIN [p] / Chapa [h] / le 191[p]6[h] / R. Vitalia de Salvaza [p, w] // MUSÉUM PARIS [P] col. Pic [h, w] // Oides / multimaculata / n m. [h, w] // TYPE [p, r] // 1369 [h, w] // [male aedeagus glued on card]”. Number of paralectotypes are unknown.

Redescription. Length 8.6–10.0 mm, width 6.5–6.6 mm. General color ( Figs 27G– 27I ) yellow; antennae yellow, antennomeres VIII–XI black; pronotum with one pair of large black spots on each side; each elytron with seven black spots: three larger ones near the suture and four smaller ones near the sides. Antennae filiform in males ( Fig. 56A ), antennomeres IV longest, III–VII slightly serrate, VIII–X elongate, length ratios of antennomeres I–XI 1.0: 0.6: 1.0: 1.3: 1.2: 1.1: 1.1: 0.9: 0.8: 0.8: 0.9, length to width ratios of antennomeres I–XI 2.3: 1.8: 3.0: 3.8: 3.5: 3.3: 3.0: 2.4: 2.2: 2.1: 2.8; similar in females ( Fig. 56B ), length ratios of antennomeres I–XI 1.0: 0.6: 1.0: 1.2: 1.0: 1.0: 1.0: 0.7: 0.7: 0.7: 0.8, length to width ratios of antennomeres I–XI 2.7: 2.0: 3.2: 3.7: 3.1: 3.1: 3.1: 2.0: 2.2: 2.1: 2.7. Pronotum transverse, 2.0 wider than long, disc convex, without reticulate microsculpture but with sparse, fine punctures; baso- and apico-lateral angles rounded; lateral margin rounded; apical margin slightly concave. Elytra oval to oblong, widest at middle, 1.1–1.3x longer than wide, disc with dense, fine punctures; slightly convex, epipleurae near lateral margins, located 9/10 distance between suture and lateral margins. Penis ( Figs 56C–56E ) relatively wider, 6.0 x longer than wide; parallel-sided; bifurcate at apical 1/3, lateral process directed mesally and apically, apices of lateral processes tapering, apices almost connected with each other; tectum elongate, curved near apex; slightly curved in lateral view, apices hooked; ventral surface with deep, broad but apically and basally narrowed notch from apex to basal 2/5; endophallic sac without sclerites. Apical margin of abdominal ventrite V in female truncate. Gonocoxae reduced. Ventrite VIII ( Fig. 56F ) transverse, apical margin broadly rounded and medially depressed, with sparse long setae along apical margin, lateral margin weakly sclerotized, spiculum extremely short. Receptacle of spermatheca ( Fig. 56G ) as wide as pump, connected to pump; pump strongly curved; proximal spermathecal duct slender, with sclerotized area at apex broader, covered with minute teeth.

Diagnosis. Members of Oides duporti Laboissière , O. leucomelaena Weise , and O. multimaculata Pic are characterized by large black spots on the elytra (larger than yellow area between spots). However, adults of O. multimaculata are easily recognized by the broadly oval body shape and elytra with four black spots near the lateral margins (elongate oval body shape and elytra with three black spots near the lateral margins in others). In males, the aedeagi of O. multimaculata differ from those of other species in possessing a more elongate, broader penis (6.0x longer than wide; extremely elongate penis in O. duporti , 6.7x longer than wide; broad penis in O. leucomelaena , 4.9x longer than wide), elongate and parallel-sided tectum (small and apically tapering tectum in others), hooked lateral processes (rounded lateral processes in others), ventral surface with deep and basally narrowed notch (with shallow and broad notch in O. duporti ; with membranous area inside apex in O. leucomelaena ), and absence of endophallic sclerites (one pair of elongate endophallic sclerites in O. duporti ; one pair of small endophallic sclerites in O. leucomelaena ).

Distribution. Laos, Vietnam. The record from China (Yunnan) ( Yang et al. 2015) is doubtful because of lack of voucher specimens.
