Oides coccinelloides Gahan, 1891: 458 (India: Sikkim); Maulik, 1936: 111 (India: Assam, Manipur, Shillong, Darjeeling); Wilcox, 1971: 6 (catalogue); Chen & Jiang, 1981: 469 (China: Xizang); Chen & Jiang, 1987: 53 (China: Xizang); Chen & Jiang, 1988: 339 (China: Xizang); Basu, 1996: 677 (India: West Bengal); Basu, 2000a: 300 (catalogue); Beenen, 2010: 491 (catalogue); Yang et al., 2015: 96 (catalogue).
Types. Lectotype ♀ (BMNH), here designated, labeled: “ Sikkim / (Dr. Hooker) [p, w, circle label] // 54 / 14 [h, b] / / Oides / coccinelloides / Type Gahan [h, w] // Type [p, w, circle label with red border] // SYN- / TYPE [p, w, circle label with blue border]”. Number of paralectotypes are uncertain.
Redescription. Length 12.8–13.1 mm, width 10.0– 10.4 mm. General color yellow (Figs 19A–19C); antennae yellow, sometimes antennomeres IX–XI darker; pronotum with one pair of longitudinal black spots laterally; metathoracic ventrites black; elytra with six pairs of transverse black spots, arranged into three transverse rows: two pairs near base, two pairs at middle, and two near apex; abdominal ventrites with lateral black spots. Antennae filiform in males (Fig. 20A), antennomeres III longest, VIII–X elongate, length ratios of antennomeres I–XI 1.0: 0.6: 1.2: 1.1: 1.0: 1.0: 1.0: 1.0: 1.0: 0.8: 1.0, length to width ratios of antennomeres I–XI 3.2: 1.8: 3.8: 3.5: 3.0: 2.7: 2.8: 2.8: 2.7: 2.3: 3.2; similar in females (Fig. 20B), length ratios of antennomeres I–XI 1.0: 0.5: 1.0: 1.1: 0.9: 0.9: 0.9: 0.9: 0.8: 0.7: 0.9, length to width ratios of antennomeres I–XI 2.9: 1.8: 3.4: 3.9: 3.4: 3.0: 3.1: 2.9: 2.8: 2.7: 3.4. Pronotum transverse, 2.1x wider than long, disc moderately convex, with lateral longitudinal grooves, lateral margins flattened, with reticulate microsculpture and fine punctures; baso-lateral angles rounded, apico-lateral angles narrowly rounded; lateral margin rounded; apical margin moderately concave. Elytra elongate oval, widest at middle, 1.2x longer than wide, disc with reticulate microsculpture and dense, fine punctures; extremely convex, humeral calli reduced; epipleurae located at 3/5 distance between suture and lateral margins. Penis (Figs 20C–20G) relatively wider, 7.3 longer than wide; parallel-sided; ventral surface with deep and narrow notch from apex to middle; tectum reduced; slightly curved in lateral view; endophallic sclerite complex comprising one sclerite at apex, with median longitudinal ridge. Apical margin of abdominal ventrite V in female (Fig. 20L) oblique, with median notch. Gonocoxae (Fig. 20M) separated, apical margins broadly rounded, with dense, long setae along apical margins. Ventrite VIII (Fig. 20J) transverse, apical margin broadly rounded and weakly depressed at middle, with mixture of long and short setae along apical margin; spiculum short and broad. Receptacle of spermatheca (Fig. 20K) as wide as pump, connected to pump, basally narrowed; pump strongly curved; proximal spermathecal duct membranous, slender and short, sclerotized area at apex covered with transverse grooves.
Variation. Specimens collected from Yunnan possess recurved, hooked endophallic sclerites (Figs 20H– 20I).
Diagnosis. Adults of Oides coccinelloides are similar to those of O. decempunctata, O. duodecimpunctata, and O. maculosa in possessing small, black spots on the elytra arranged into three transverse rows. They differ from others in possessing one pair of lateral black spots at the pronotum (entirely yellow pronotum in O. decempunctata) and yellow scutellum (black scutellum in O. duodecimpunctata and O. maculosa), two pairs of black spots near the apices of the elytra (one pair in O. decempunctata; three pairs in O. maculosa), and strongly convex elytra (epipleurae located at 3/5 distance between suture and lateral margins; moderately convex elytra in O. decempunctata, epipleurae located at 5/7 between suture and lateral margins; less convext elytra in O. duodecimpunctata and O. maculosa, epipleurae located at 9/10 between suture and lateral margins). Aedeagi of male O. coccinelloides differ from others in lacking a tectum (recurved tectum in O. decempunctata; small and apically tapering tectum in O. duodecimpunctata; bifurcate and rounded tectum in O. maculosa), presence of a deep, narrow notch on the ventral surface of the penis (deep and broad notch in O. duodecimpunctata and O.
maculosa; membranous apex in O. decempunctata), and possessing one small, hooked, and erect endophallic sclerite (one large, hooked and erect sclerite in O. maculosa; one elongate and parallel-sided sclerite in O. duodecimpunctata; endophallic sclerites absent in O. decempunctata).
