Type species

Leiparthrum bituberculatum Wollaston

Adapted from Wood 1982, p. 363-368


Diagnosis

Liparthrum is similar to Chaetophloeus LeConte. It can be distinguished by the 4-segmented antennal funicle, the unsutured club, and the lack of Chaetophloeus’ highly developed anterior margin crenulations.


Description

Species in this genus range in length from 0.75 to 1.30 mm and from 2.0 to 2.2 times as long as wide. Their color ranges from light to very dark brown. The pronotum is wider than long with an asperate surface, and the male’s anterior margin is armed by a pair of teeth. The scutellum is not visible. The elytra’s anterior margin is armed with five to six pairs of equally sized crenulations from suture to striae five. The declivity is convex and unarmed. The vestiture consists of rows of interstrial scale-like setae and recumbent strial bristle-like setae. The frons is sexually dimorphic, ornamented by setae in females. The anterior margin of the compound eye is entire. The scape is usually shorter than the 4-segmented funicle. The oval club has no sutures. The procoxae are contiguous.
