Reuteria querci Knight 
Reuteria querci Knight (19394, p. 131). 
This species is allied to irrorata (Say), 
but is distinguished by the structure of the 
male genital claspers, fig. 124; the females 
of guerci and irrorata may be separated by 
the absence in querci of well-formed green 
blotches on the corium and the presence of 
paler veins in the membrane.
