Oides cyanella Jacoby

( Figs 8G– 8I View FIGURE8 , 21 View FIGURE 21 )

Oides cyanella Jacoby, 1886: 43 ( Indonesia: Ternate island); Weise, 1924: 3 (catalogue); Laboissière, 1932: 151 (diagnosis); Wilcox, 1971: 7 (catalogue); Kimoto, 1990: 218 (catalogue).

Types. Holotype ♀ ( MCSN, by monotypy), labeled: “ Ternate / X / Beccari 1875 [p, w] // Sp. n. [h, w] // Typus [p, w, red letters] // cyanella / Jac. [p, w] // Oides / cyanella Jac. [h, g]”.

Redescription. Length 10.1–12.4 mm, width 5.1–6.7 mm. General color ( Figs 8G– 8I View FIGURE8 ) yellow; antennae blackish but three basal antennomeres yellowish brown; elytra metallic blue, with narrow, yellow lateral margin. Antennae filiform in males ( Fig. 21A View FIGURE 21 ), antennomeres IV longest, III–XI slender, VII apically broadened, length ratios of antennomeres I–XI 1.0: 0.6: 1.0: 1.3: 1.2: 1.1: 1.2: 1.0: 1.0: 0.9: 1.0, length to width ratios of antennomeres I–XI 2.9: 2.2: 3.3: 4.2: 3.5: 3.4: 3.1: 3.1: 2.9: 2.7: 3.4; similar in females ( Fig. 21B View FIGURE 21 ), length ratios of antennomeres I–XI 1.0: 0.6: 0.9: 1.2: 1.1: 1.0: 1.1: 0.9: 0.9: 0.8: 0.9, length to width ratios of antennomeres I–XI 3.2: 2.3: 3.4: 4.5: 4.1: 3.6: 3.3: 3.1: 3.1: 2.9: 3.8. Pronotum transverse, 2.4 wider than long, disc convex, lateral margins flattened, with reticulate microsculpture and dense, coarse punctures; baso- and apico-lateral angles broadly rounded; lateral margin rounded; apical margin slightly concave. Elytra elongate oval, parallel-sided, 1.5x longer than wide; disc with reticulate microsculpture and dense, coarse 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 middle; humeral calli prominent. Penis ( Figs 21C–21E View FIGURE 21 ) slender, 8.0x longer than wide; widest at apical 1/4, parallel-sided, apex of dorsal surface bifurcate at apical 1/4; tectum elongate, apically broadened, apex truncate; slightly curved in lateral view, apex narrowly hooked; ventral surface with extremely deep and basally narrowed notch from apex to basal 1/5; endophallic sclerite complex comprising one pair of elongate, basally and apically tapering sclerites. Apical margin of abdominal ventrite V in female truncate. Gonocoxae reduced. Ventrite VIII ( Fig. 21G View FIGURE 21 ) transverse, apical margin broadly rounded and weakly depressed at middle, with extremely long setae along apical margin, spiculum reduced. Receptacle of spermatheca ( Fig. 21H View FIGURE 21 ) as wide as pump, connected to pump; pump strongly curved; proximal spermathecal duct membranous, slender and short, sclerotized area at apex covered with minute setae.

Variation. Specimens from Bacan island have the hook-like apex of the penis more slender and the upper margin convex instead of straight as in the typical specimens ( Fig. 21F View FIGURE 21 ).

Diagnosis. Adults of this species are similar to those of O. limbata Blanchard from New Guinea in possessing parallel-sided, metallic blue, densely punctate elytra, but differing by its more elongate elytra and narrower yellow lateral margin.
