[December 
on which they enclose a gently concave median area) ; and ovipos- 
itor 0.27 (instead of 0.15) as long as the fore-wing. 
Another member of the Albomarginatus Group closely related 
both to jakulicai and ramirezi is the northwest Argentine C. tafiae 
Porter, but females of that species easily may be distinguished from 
the foregoing because they have the subalarum mostly white, the 
lower hind-corner of the mesopleuron marked with a large white 
blotch, the mesopleuron normally in great part without intercalated 
wrinkling among the punctures, the fore-tibia distinctly inflated, and 
the ovipositor 0.32 (instead of 0.1 5-0.21) as long as the fore-wing. 
The male of jakulicai differs from that of tafiae in many of the 
same characters mentioned for the female and, moreover, may be 
separated by reference to couplet 1 1 of the author’s key to the males 
of South American Coccygomimus (Porter, 1970, p. 34) where it 
is treated under the name “ramirezi” . 
Habitat notes : The female holotype and one of the male para- 
types were collected by a Malaise trap stationed in virgin Selva 
Tucumano-Boliviana at about 400 m. elevation along the Rio Pes- 
cado approximately 40 km west of Aguas Blancas in Salta Province. 
This is a very humid and almost tropical zone, without recorded 
frosts and with a short but definite dry season which becomes most 
pronounced between August and October. The second male para- 
type comes from Posta de Lozano, an area of mingled Selva and 
Chaco biota, located 18 km north of San Salvador de Jujuy at 1600 
m. elevation. 
Specific name: For Dr. Domingo Jakulica.

merous visits to the virgin subtropical forest near Aguas Blancas, 
where he owns extensive properties and maintains a camp that has 
served as base for our collecting.
