Trichocnemis is a genus of beetles in the longhorn beetle family, Cerambycidae. Its species have often been treated as members of genus Ergates. Authors who separate the two genera differentiate Trichocnemis by a proportionally smaller head, the shape of the mandibles, the length of the antennae, and various other details in the morphology of the body and legs.[1]
Beetles in genus Trichocnemis have large, elongated bodies in shades of brown, usually with lighter elytra. They have small heads with big eyes and relatively short antennae. The mandibles are less than half the length of the head and curve inward.[1]
Trichocnemis species are distributed in the western United States and Baja California.[1]
There are two species:[1]

Trichocnemis er en slekt av biller som hører til familien trebukker (Cerambycidae).
Store (45-60 millimeter), kraftige, mørkbrune trebukker. Antennene er forholdsvis korte og tynne. Pronotum er mer eller mindre trapesformet med pigger ved for- og bakhjørnene. Dekkvingene er parallellsidige med fine, opphøyde lengderibber og nesten rettviklede "skuldre".
Larvene borer i død ved av bartrær (furu og Douglasgran]. De etterlater seg grove ganger i veden. Utviklingen tar 2-3 år. Disse billene besøker ikke blomster, og mange arter er nattaktive. En del av dem kommer til lys.
Slekten er utbredt i Nord-Amerika.
