This species is known from G. Dorcas by the softness of the fur, 

 the absence of the dark streak on the side and on the edge of the anal 

 disc ; both these species have the under sides of the feet and the 

 back edge of the tarsus white, while in G. Dorcas there is a tuft of 

 soft black hair under the feet, and the back of the tarsus is red.
