This species is respectfully dedicated to Dr. T. Miyake, at 

 whose suggestion and through whose kindness I was able to take 

 up the study of Japanese caddis-fiies. 



This species is very closely allied to G. admorsus, but can be 

 distinguished by the markings of the fore-wing and the structure of 

 the male genitalia.
