1972 ] Porter — Coccygomimus 333 
basal 3/4 of postpetiole duller and more strongly sculptured than in 
female, with coarser micro- wrinkling which is irregularly trans- 
biased on central field but more reticulate laterad, as well as with 
more numerous and more discrete intercalated punctures, particularly 
on lateral field. Succeeding tergites: 2 rather dully shining with 
strong, reticulate to trans-biased micro-wrinkling and abundant, mod- 
erately large, distinct but shallow to obscure, mostly adjacent to 
confluent punctures ; 3 and 4 similar to 2 ; but 5-7 progressively 
more shining and with weaker punctures and wrinkling. 
Types: The female holotype and one male paratype have been 
deposited in the collection of the Miguel Lillo Institute, San Miguel 
de Tucuman, Argentina. The second male paratype is in the col- 
lection of Charles C. Porter (RFD 3, Cambridge, Maryland, 
U.S.A.). 
Discussion: The first record of C. jakulicai was a male col- 
lected near San Salvador de Jujuy during March of 1969, and in 
the author’s revision of the South American Coccygomimus (Porter, 
1970, P* no) that specimen was associated tentatively with a Bo- 
livian female therein described as C. ramirezi. However, subsequent 
discovery of a Saltenan female obviously conspecific with the male 
from Jujuy but different in several important features from the fe- 
male of ramirezi confirmed that this Argentine form, although closely 
related to the Bolivian Coccygomimus , must be regarded as distinct. 
Specifically, jakulicai may be distinguished from ramirezi by the 
following characters (see figures 2, 3, 4, and 5) : 
Tegula mostly white (instead of mostly blackish) ; gaster apically 
with extensive reddish staining; ground color of front femur red- 
dish (instead of brownish black) ; ground color of fore-tibia pale 
red (instead of brownish black) ; hind-coxa red with a little dusky 
staining on apex (instead of red on basal 1/2 and black on apical 
1/2) ; punctures of mesocutum medium sized and mostly well de- 
fined (instead of rather small and in large part very superficial and 
inconspicuous) ; mesopleuron and metapleuron more coarsely sculp- 
tured ; propodeum less elongate, its basal face with rather strong and 
mostly regular transverse wrinkling (instead of with generally finer 
and extensively irregular wrinkling) ; postpetiole 0.65 (instead of 
0.87) as long as wide at apex; first gastric tergite in profile with 
a rather high and rounded hump, its dorsal carinae faintly suggested 
on the hump and for a short distance rearward (instead of with a 
lower hump and with the dorsal carinae well defined on the hump 
and clearly traceable rearward about 2/3 the length of postpetiole.
