Identification
The hairy eyes + antennae (with thread-like, arching arista) inserted at top of head separate this genus from our other Acroceridae. Mouthparts typically not visible. Thorax & abdomen usually conspicuously "furry"; body generally unicolorous, black to reddish-brown. Wings typically hyaline in male, somewhat infuscated in female.
The common eastern T. surphuripes has anal vein reaching wing margin and forming a widely open anal cell. It is typically golden hairy, and males have a very strong tooth on the costal wing margin (even more pronounced than in Pterodontia males).
The other eastern species, T. gagatinus, is extremely rare, with wings entirely infuscated & a closed discal cell.
The common western T. diligens has anal vein either terminating in the cubital cell (thus forming a closed anal cell), or fading out before the margin. Wing with no tooth in either sex.
Range
T. diligens: west of the Rockies
T. sulphuripes: e. US
T. gagatinus: Pennsylvania (rare)
T. brunnipennis: Haiti
