Anorostoma currani Garrett 
Fiacure 48 
Anorostoma currant Garrett, 1922, p. 176—Czerny, 1927b, p. 37.—Curran, 
1933, p. 5. 
The stout spines of the-epiphallic process easily distinguish the 
male of this species. The female is not known, although two female 
specimens with the same collection data as an Anorostoma currant 
Garrett male have been examined. They appear similar to the 
female of A. coloradense Garrett. 
Maur.—Head, thorax, and legs yellow with grayish pollinosity, 
except front darkened to orange; abdomen yellowish brown to blackish 
in ground color with grayish pollinosity. 
Cheek-eye ratio about 0.65. 
A median row of setae lies between the dorsocentrals, with other 
scattered setae present; sternopleural hairs may be slightly longer 
than in related species. 
The general appearance of this species is very similar to A. jerser 
Garrett, A. coloradense Garrett, and related species. 
Epiphallic process with large notch in ventral edge and with long 
stout spines. 
DistrRiBuTION.—British Columbia, Washington, Colorado, Montana, 
Manitoba, North Dakota; June—September. 
Remarks.—The Garrett collection contains a specimen labelled 
“Holotype, Anorostoma currani var. mica.’ The specimen is heavily 
covered with mold and I could not observe any significant difference 
from the type of A. currani Garrett. The allotype bearing the same 
determination label had strong terminal abdominal spines similar to 
A. jersei Garrett. It was not collected in association with 
the holotype.

The shape of the epiphallic process and of the surstylus best dis- 
tinguishes the male of this species from all others. The cheek-eye
