242 DIPTERA 
Type species : P. PAanlasma, Mik, Coquillett's designation in 1903.  Coquillett made this purely 
a synonym of Roedería, since its main characteristic, the presence of the acrostichal setulz is inconstant. 
I retain the name here, like the two following groups, as a matter of convenience. The species are not 
phyletically distinct, and since the characters chosen are artificial combinations, species occur which do 
not conform in all respects to the definitions given. 
SuscENUS CHAMZEDIPSIA, Mik 
Stigma elongate, as in Eucelidia, costal spines not projecting; preapical bristles of the femora with 
setze ; rows of acrostichals incomplete, at most some reclinate setulze present on the anterior part of the 
notum, scutellum typically without setulz, alternate smaller setulz usually present in the dorsocentral 
rows;arista usually blunt at the end. 
Type species : C. Aasíala, Mik, the only species originally mentioned. 
SuscENUS RCEDERELLA, ENGEL 
Stigma elongate, oval, costal spines rather prominent; preapical bristles of the femora absent, front 
femora with a comb of three or four bristles near tip; only short anterior acrostichals present, scutellum 
with marginal setulz, five dorsocentral bristles present and no intermediate ones, : 
Type species : R. Csernyi, Bezzi, by original designation.
