Redescription. Length 3.7–4.3 mm, width 1.4–1.8 mm. General color black, but mouth parts, antennae, apices of femora, bases of tibiae, and tarsi paler (Fig. 9 F). Antennomere I slightly swollen in males (Fig. 12 A), length ratios of antennomeres I–XI 1.0: 0.4: 0.6: 0.6: 0.6: 0.6: 0.7: 0.7: 0.6: 0.6: 0.7, length to width ratios of antennomeres I–XI 3.0: 1.5: 2.5: 2.5: 2.6: 2.6: 2.9: 2.9: 3.0: 2.7: 3.8; antennomere I more slender in females (Fig. 12 B), length ratios of antennomeres I–XI 1.0: 0.4: 0.6: 0.6: 0.7: 0.7: 0.7: 0.7: 0.6: 0.6: 0.8, length to width ratios of antennomeres I–XI 3.7: 1.8: 2.7: 2.8: 2.9: 2.7: 2.7: 2.8: 2.9: 2.7: 3.6. Elytra 1.8x longer than wide, surface with erect, pale, dense, and elongate setae; and fine punctures. Apical margin of last abdominal ventrites with two shallow incisions in males (Fig. 12 G); but widely rounded in females (Fig. 12 H). Penis (Figs 12 C–12D) slender, 6.1 x longer than wide, gradually narrowed towards apex; apex of dorsal surface with deep notch; apex of ventral surface with shallow notch; almost straight in lateral view, apex with deep notch between dorsal and ventral surface; ventral surface smooth. Endophallic spiculae long, about 0.6 x as long as penis, apex trilobed, median lobe medially swollen, with dense lateral setae subapically, lateral lobes slender; eight pairs basal horn-like spiculae, basal pair longest, apically shortened. Gonocoxae (Fig. 12 E) extremely slender, 6.2 x longer than wide, sides narrowed at apical 1/10 and 3/10; apices narrowly rounded; inner margins approximate from apex to midpoint, apex with nine setae; extremely slender from half to midpoint but abruptly widened at base. Ventrite VIII (Fig. 12 F) well sclerotized; spiculum elongate; apex square, apical margin truncate, with dense short setae; disc with several long setae at sides. Receptacle of spermatheca (Fig. 12 I) moderately swollen, narrowly separated from pump; pump strongly curved but not apically narrowed; proximal spermathecal duct slender, shallowly projecting into receptaculum.
