Fig. 14. Chromocryptus golbachi, Holotype. Body in lateral view, showing 
habitus and color pattern. 
very sharp and high; apical trans-carina strong but irregular; cristae 
short-cuneate, very large and strongly projecting; median longitudi- 
nal carinae irregular but well developed, areola and median apical 
area defined; surface, especially on apical face, very coarsely reticu- 
lately wrinkled. First gastric tergite: postpetiole 1.2 as wide apically 
as long from spiracle to apex; surface of postpetiole almost uni- 
formly with large and strong, subadjacent to a little reticulately 
confluent punctures; setae equal or exceed the length of their inter- 
spaces; basal expansion of petiole a low and rounded flange. 
Type Material. Holotype $: ARGENTINA, Jujuy Province, 
Posta de Lozano, 21-III-1969, C. Porter. Paratypes: 1? and 
Argentina, Jujuy Province, Huacalera, 2800 m, 25-III-1969, C. 
Porter. Holotype in Florida State Collection of Arthropods. Para- 
types in Collection of Charles C. Porter. 
Relationships. This species shows close affinity to the Argen- 
tine C. prosopis and to other members of the Planosae complex 
within Chromocryptus. Its diagnostic features are summarized in 
the key and in the discussions of C. tomsici and C. hiibrichi. 
Field Notes. Chromocryptus tomsici seems to replace the low- 
land Chaco C. prosopis in the mountains of northwest Argentina. 
The habitat of the type female, a complex ecotone at 1600 m, 
already has been discussed under the treatment of C. alvaradoi. 
Huacalera, where the paratypes of C. tomsici were collected, is 
much drier and colder than Posta de Lozano. It belongs to the 
Prepuna Biome, a high Andean desert characterized by such xeroph- 
ilous shrubs as Schinus, Prosopis, Acacia, and Cercidium, as well
