http://zoobank.org/urn:lsid:zoobank.org:act:EE5360CF-2945-4FC5-8FFD-28686738F54E Description:Length male, 3.0– 3.5 mm; female, 2.8–3.0 mm. Integument black, shining. Eyes rather widely separated by a distance slightly less than width of rostrum at midlength. Rostrum 1.09–1.15x length elytra in male; 1.09–1.28x length elytra in female. Antennal insertion at about apical 2/ 5 inmale, slightly before middle in female. Prothorax constricted anteriorly, globose, widest at about middle; punctures dense, large and deep, subcontiguous, forming striolae on disc and laterally on flanks; erect setae absent. Elytra in dorsal view widest at about midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; setae absent. Strial punctures evident, large, deep; striae deeply impressed throughout length. Membranous wings absent. Abdominal ventrite 1 of male flat basally, in middle near posterior margin with two very small, approximate swellings, each with minute patch of setosity at tip; of female, uniformly convex in middle near posterior margin. Ventrite 2 of both sexes with two large, deep pits on steeply declivious posterior face (fig. 14a). Ventrite 5 of male with rounded very shallow impression in apical one-half; of female, uniformly convex. Legs with all femora simple, ventral margin lacking any trace of tooth; tarsal claws simple, no basal tooth. Aedeagus (fig. 21) subequal in width towards apex and base, internal sac with pair of elongate basal sclerites subparallel, joined anteriorly as a fine arch, each with distinct basal projection. Female not dissected.

Derivation of species name:This species is named ‘bipunctiventris’ after the two large, deep pits on the posterior face of abdominal ventrite 2 (fig. 14a).
Natural History:Adults were collected in elfin and hardwood forest litter ( 842–1086 m) and beating vegetation.
Comments:The two large, deep pits on the posterior face of abdominal ventrite 2 of both sexes (fig. 14a) is distinctive for this species.
