This genus was proposed by Rubsaamen with Diplosis 
galliperda F. Lw. as type because it was found that the type 
of Clinodiplosis Kieff., C. cilicrus Kieff. has the anterior 
claws toothed. The species previously noticed by the writer as 
Clinodiplosis fall in this genus. 
Here belong a number of small, yellowish species which may be 
recognized by the simple claws, the quadriarticulate palpi, the lack 
of a conspicuous lobe or spine on the basal clasp segment and by 
the long, linear, usually narrowly rounded ventral plate. The simple 
basal node of the flagellate antennal segments of the male serves to 
separate members of this genus from Xenodiplosis Felt. The known 
females of American species have moderately short-stemmed, 
cylindric flagellate antennal segments and a usually short ovipositor 
with long, slender lobes. 
Several American species have been reared from leaf galls on 
Spiraea; one from the roots of a plant and another, P. caryae 
Felt, is probably an inquiline in various Caryomyia galls on hickory,
