 The original description of this species was based on a single 

 female specimen. In the present collection both sexes are 

 represented and the male is described herewith. The species is 

 close to the form described in this article as R. brevioricornis liut 

 differs in the longer antennae, the slightly different male genitalia 

 and the usually paler coloration. 

 MaZc— Length, 7 mm.; wing, 7.6 mm. 



Rostrum of the male longer than in the female. Antennae moderately 

 long for this genus of flies, in the male sex being nearly three times the length 

 of the rostrum; flagellar segments long-cylindrical, the first flagellar segment 

 nearly twice as long as the second scapal segment and subequal to the second 

 and third flagellar segments. 



Thorax pale brownish yellow, the median praescutal stripe dark brown, 

 the lateral stripes much less distinct; scutal lobes very dark brown; post- 

 notum usually pale with a dark brown median line, in some cases the entire 

 median area of the postnotum being suffused. 



Abdomen dark brown above, the sternites pale; hypopygium brownish 

 yellow. Male hypopygium with the outer pleural appendage short, about 

 two-thirds the length of the inner appendage, the tip produced into a slightly 

 curved point, before the apex on the outer or caudal face with a very blunt, 

 appressed tubercle.
