Diagnosis

This exotic genus from the subtribe Tomicina is closely related to another introduced genus to North America, Hylurgus Latreille. Both have a 6-segmented funicle. Tomicus are less hairy overall and the surface of both the frons and the declivity are shiny versus asperate on Hylurgus.


Description

The size of the species on this genus ranges from 2.9 to 5.4 mm in length. The elytral color ranges from yellowish brown to almost black with a darker pronotum. The pronotum is wider than long, shiny and unarmed. The scutellum is small and depressed. The declivity is convex bearing interstrial granules with a vestiture of erect hair-like setae. The frons has a median vertical carina above the epistoma. The anterior margin of the compound eye is entire. The scape is as long as the 6-segmented funicle. The club is ovate with three straight sutures. The procoxae are contiguous with no prothoracic elevated ridges.
