NEW DIPTERA OF THE FAMILY PHORIDAE 
FROM PARAGUAY . 1 
By Charles T. Brues. 
The present short communication relating to Paraguayan Pho ridete 
is based upon some very interesting material recently accumulated for 
the Hungarian National Museum by Mrs. Babarczy and Mr. Fiebrig and 
sent to me by Dr. Kertész for examination. 
The only Phoridae hitherto credited to the fauna of Paraguay are 
three in number 2 and the present collection serves to add four more, 
three of which are undescribed while the other was previously known 
from Bolivia. One genus (Gymnophora) common to northern Europe 
and Nort America appeare in South America for the first time, repre¬ 
sented by a species closely similar to its northern congener. 
Phora Latr. 
There is an additional Paraguayan species in the present material, 
very similar to Ph. paraguayana Brues (Ann. Mus. Nat. Hungarici, 
Vol. V, 1907. p. 400) but quite distinct as can be seen from the fol¬ 
lowing key which aims to distinguish as clearly as possible the species 
of Phora which have the fore tibiæ furnished with a series of four or 
five small setæ, and have the proboscis of the female more strongly 
chitinized than usual. Whether this group is really of subgeneric value, 
I do not feel sure, but it is very conveniently designated as Group 
Dorniphoi a Dahl.

2 Phora paraguayana Brues, Aphiochaeta meridionalis Brues and A . pauxilla 
Brues described in volume 5 of the present journal (1907. pp. 400—403). The pecu¬ 
liar termitophilous fly, Termitomastus leptoproctus Silvestri from Argentine Re¬ 
public is erroneously attributed to the Phoridæ by Brethes. (An. Mus. Nac. Buenos 
Aires, Vol. XVI, p. 291.) It is one of the nematocerous Diptera.
