Genus Pseudomyrmex Lund 
Janzen (1967: 344). Beltian bodies are cut up by the workers 
and fed to the larvae. 
The following species of Pseudomyrmex are compared with Ps. 
alliodorae 1956: 379); only differences are given here. 
Pseudomyrmex adustus Borgmeier. Length (through spiracles) 
about 4.8 mm; straight length about 4.6 mm. Body hairs: (2) 
0.05-0.25 mm long, longest of AI-AV; (3) 0.2-0.25 mm long, 2 
only on each T1-3 and AI-AIII. Head hairs more numerous and 
0.05-0.25 mm long. Posterior surface of labrum with a cluster of 3 
sensilla in the middle of each half. (Material studied: 7 larvae from 
Brazil, courtesy of Dr. K. Lenko.) 
Pseudomyrmex belti fulvescens Emery (= Ps. ferrugineus F. 
Smith). Janzen 1967: Description p. 394; feeding of larvae p. 416- 
417; handling of larvae p. 418. Similar information in Janzen 
1966. 
Pseudomyrmex elongatus Borgmeier. Length (through spiracles) 
about 3.8 mm; straight length about 3.6 mm. Body hairs longer: 
(1) 0.006-0.018 mm long; (2) 0.018-0.2 mm long; (3) 0.175-0.22 
mm long, 4 in a row across the dorsum of each T1-3 and AI-AIV. 
Head hairs more numerous and slightly longer (0.01-0.05 mm long). 
(Material studied: 15 larvae from Brazil, courtesy of Dr. K. Lenko.) 
Pseudomyrmex schuppi Forel. Length (through spiracles) about 
5.9 mm; straight length about 5.7 mm. Largest spiracles on AI. 
Body hairs longer: (1) 0.013-0.025 mm long; (2) 0.038-0.25 mm 
long; (3) 0.25-0.33 mm long, 4 in a row across the dorsum of each 
T1-3 and AI-AIII. (Material studied: numerous larvae from Brazil, 
courtesy of Dr. K. Lenko.) 
Pseudomyrmex subtilissimus Emery. Length (through spiracles) 
about 4.3 mm; straight length about 3.9 mm. Body hairs ( 1) 0.006- 
0.018 mm long; (2) 0.018-0.15 mm long; (3) about 0.15 mm long, 
4 in a row across the dorsum of each T1-3 and AI-AIV. Head hairs 
slightly longer (0.025-0.05 mm long). (Material studied: 6 larvae 
from Brazil, courtesy of Dr. K. Lenko.) 
Pseudomyrmex termitarius F. Smith. Length (through spiracles) 
about 5.1 mm; straight length about 4.7 mm. Body stouter. Body 
hairs about twice as numerous: (1) 0.013-0.05 mm long; (2) 0.05- 
0.275 mm long; (3) 0.25-0.35 mm long, 4 in a row across dorsum 
of each T1-3 and AI-AIV. Head hairs more numerous, longer 
(0.013-0.05 mm long) and finely denticulate. Labrum with width 
twice the length, with anterior lobes more prominent and with 2
