(versus mostly red), malar space 0.9- 1.1 as long as basal width of 
mandible (versus 0.8-0. 9), propodeal spiracle 1. 7-2.0 as long as 
wide (versus 1.4- 1.5), and large punctures widely scattered on 
median field of postpetiole (versus rather dense). 
Chromocryptus huebrichi also much resembles the northwest 
Argentine C. tomsici, C. prosopis, and C. golbachi . These species are 
distinguished in the key but also show some additional differences, 
as summarized here: female of C. huebrichi with 1st flagellomere 
5. 3-5. 5 as long as deep at apex (5. 8-6.0 in C. tomsici ); malar space 
in female C. huebrichi 0.90-1.0 as long as basal width of mandible 
(0.84-0.85 in C. tomsici ); propodeal spiracle 1. 7-2.0 as long as wide 
in C. huebrichi ( 1.3- 1.5 in C. prosopis ); female postpetiole with scat- 
tered punctures medially in C. huebrichi (with dense punctures, even 
on median field, in C. tomsici ); no white on male postscutellum in 
C. huebrichi (postscutellum mostly white in C. golbachi ); malar 
space 0.70 as long as basal width of mandible in C. huebrichi males 
(0.80 in C. tomsici, 0.53-0.66 in C. prosopis, and 0.80-0.85 in C. 
golbachi ); male postpetiole 1.4 as wide apically as long from spiracle 
to apex in C. huebrichi (1.2 in C. tomsici, 1.6 in C. prosopis, and 
1.8-1.9X in C. golbachi); and male postpetiole with large punctures 
sparse medially in C. huebrichi (subadjacent to reticulately confluent 
in C. prosopis and C. golbachi ). 
The above-cited differences show that C. huebrichi, C. planosae, 
C. tomsici, C. prosopis, and C. golbachi manifest multiform but 
often slight phaenotypic divergence. When more specimens are col- 
lected, they should furnish evidence about the extent of geographic 
and intrapopulation variability among these Chromocryptus and 
prove whether this widely distributed Planosae group consists 
mainly of discrete species or of intergrading geographic races. 
Habitat Notes. Most of the type series was collected near 
Curitiba, Brasil on the 1000 m high, cool, wet Planalto of Parana 
State. This region is characterized floristically by subtropical wet 
forests of myrtaceous and other angiosperm trees plus Araucaria 
and Podocarpus. The forests are broken in places by grasslands, 
whose biota recalls that of the Argentine pampas. 
I have no information as to the precise microhabitats where C. 
huebrichi was collected. 
Hosts. Mallo (1954, as cited above) reared C. huebrichi from the 
lasiocampid moth, Titya proxima.
