DESCRIPTIONS AND RECORDS OF 
NEOTROPICAL CONOPIDAE (DIPTERA) 
By Sidney Camras 
Chicago, Illinois 
The first part of this paper may be considered an ad- 
dendum to my work on New World Conors and allies 
(1955, Proc. U.S. Nat. Mus., 105, 155-187). A number 
of other apparently new forms have been seen; but I am 
awaiting more material, or the opportunity for a revisional 
study in the case of Zodion. 
Diconops, subgen. nov. 
Belonging to the genus Conops, but having a relatively 
long and narrow second abdominal segment. Second ab- 
dominal segment (female) dorsally, about three times as 
long as wide, sides parallel. Third segment about three- 
fourths as long as second, apex nearly two times as wide 
as base. One propleural bristle on the type species, none 
on the other species. Posterior margin of eye more con- 
cave than usual. Polished triangular area at posterior 
margin of eye nearly absent. 
Type : Conops trichus, sp. nov. 
This subgenus could be placed in Physoconops , as a 
group lacking the ocellar tubercle; but I consider the 
absence of the ocellar tubercle more characteristic of the 
genus Conops than the wide abdomen. 
The male is as yet unknown. 
Conops (Diconops) trichus, sp. nov. 
Holotype $ : Brazil: Nova Teutonia, Santa Catarina, 
Nov. 1952, F. Plaumann (author’s collection). 
Vertex yellow, rounded anteriorly, black laterally. Front 
yellow with black “T” pattern. Face and upper grooves 
yellow. Lower face and grooves, and cheeks black. Facial 
grooves and orbital yellow pollinose. Occiput black. Anten-
