latter has a length one-half greater than its diameter and is thickly 

 clothed with a long, stout, strongly curved setae; fourteenth seg- 

 ment reduced, the fifteenth long, slender, swollen basally. Palpi; 

 first segment short, irregular, the second with a length about thrice 

 its diameter, the third and fourth, each subequal, about one-half 

 longer than the second, the fourth somewhat dilated. Thorax and 

 abdomen a variable yellowish brown. Halteres yellowish. Legs 

 mostly fuscous yellowish; the first tarsal segment, the base and the 

 apex of the second, the apex of the third and fourth broadly white 

 margined, the fifth white. In some specimens the basal banding 

 of the second tarsal segment is much reduced. Claws slender, 

 strongly curved, the anterior unidentate. Ovipositor short, stout, 

 the terminal lobes broadly oval and thickly setose. Type Cecid.

Members of this genus have the anterior tarsal claws unidentate 

 and may be separated from the allied Mycodiplosis by the more or 

 less conspicuous, setose or nearly glabrous basal lobe at the internal 

 basal angle of the basal clasp segment. The ventral plate in the 

 type species is as long as the style and broadly rounded apically, 

 while the harpes are strongly chitinized. Type Mycodiplosis
