Fig. 26. Gerarulus racUalis, drawings based on holotype no. YPM 37. a. fore 
wing. b. hind wing. 
Diagnosis 
This is the smallest of all the gerarids and its size seems, at pres- 
ent, to be the most distinguishing feature of this species. 
Geological range: Westphalian D. Occurrence: Mazon Creek, 
Illinois, U.S.A. 
Holotype: YPM 37. Specimen examined. Obverse and reverse 
halves. This specimen is somewhat unusual in that both fore and 
hind wings are stretched out on one side of the body and do not 
overlap at all. The abdomen appears to be rather slender. The pro- 
thorax is missing. 
Genus Anepitedius 
Anepiteciius Handlirsch 1911:318, 1919:30. 
Description 
Owing to the poor state of preservation of the type specimen, it is 
impossible to describe diagnostic characters for this genus.
