features as in female. Subgenital plate tapering to a sharp point, 
somewhat hirsute, as figured for delicatus Turner by Evans, 
1966b, Fig. 63. Genitalia also like those of delicatus {Void, Fig. 60) 
except parameres more elongate, equal in length to parapenial 
lobes and digiti. 
Paratypes. — 1 <5, same data as type and allotype; 2 99, 15 dd, 
same data except various dates Jan., Feb., Aug. -Oct. 1973-74 
Malaise trap. Porter & Stange) [Inst. Miguel Fillo, Mus. Comp. 
Zool., Coll. C. C. Porter], 
Variation. — The female paratypes resemble the type closely, 
but in both the spots on tergite 5 are narrowly connected medial- 
ly. The males vary in length from 3.5 to 6.0 mm. The pale spot 
on the scutellum is present in all males, but that on the meso- 
scutum is reduced or absent in the smaller specimens. The spots 
on tergite 2 are very small in several males and entirely absent 
in two; but one male has a broad, pale band on tergite two and 
small spots on tergite three. Leg color is also somewhat variable. 
Remarks. — The females run to delicatus Turner in my 1967 
key, but differ from that species in the narrower front and in 
lacking any trace of rufous on the abdomen, as well as in several 
other details of color pattern. The males run to the couplet sepa- 
rating delicatus Turner and tucumanus Evans but the genitalia 
differ from either of those species and the pattern of white spots 
is distinctive.
