Annegialia ataeniformis
Howden 1971: 1468, UT, NV.
Life History. Unknown. The few specimens known have been collected at light.
Larvae. Unknown.

Status of Classification. Annegialia is a very unusual beetle, with head characters of Aegialiini and body characters more like Eupariini. It is presently placed in the Eupariini (Gordon and Cartwright 1988), but this placement needs to be restudied. Annegialia needs to be included in higher level analyses, but its rarity in collections makes this difficult.
