Burnham — Geraridae 
45 
Remarks 
It is clear that this genus belongs in the family Geraridae: the 
prothorax is distinctively shaped, and the limited venational charac- 
ters are in accordance with the family. Unfortunately, since this is a 
monotypic genus and based on a single, poorly preserved specimen, 
it is impossible to assess its relationship to other taxa in the family. 
Geological range: Westphalian D. Occurrence: Mazon Creek, 
Illinois, U.S.A. Type species: Anepitedius giraffa. 
Anepitedius giraffa 
Anepiiedius giraffa HancUirsch 1911:318, 1919:30.

Remarks 
This species deviates from the other species in the family by hav- 
ing a combination of narrow wings and a robust prothorax. Unfor-
