Cotype No. 26816, Museum Comp. Zook, Gynotype No. 74, 
Haskins Collection. 
Pseudomyrma wessoni var. tuberculata var. nov. 
Worker. 
Head about as broad as long with very large eyes, occupying 
more than half of the convex sides. Mandibles with two large 
apical teeth and several smaller ones, all brown; heavily stri- 
ated; the clypeus with a sinusoid anterior border. Head and 
antennal scapes densely punctate and opaque. Prothorax mar- 
ginate, deeply impressed mesepinotal suture and the epinotum 
with a faint indication of epinotal spines on the junction of the 
epinotal base and declivity. (This is a very unusual feature in 
workers of Pseudomyrma). Petiole in profile similar to that of 
wessoni , but shorter. Postpetiole very short and much broader 
than long. Abdomen stubby. 
Coloration uniformly dark yellow or light brown. The pilos- 
ity consists of sparse long hairs. The pubescence is very fine 
and somewhat more abundant on the head and gaster. 
Type locality: Lima, Peru. 
The new variety is related to P. wessoni from which it differs 
by the structure of the pedicel, the small epinotal tubercles and 
the darker coloration. The sculpture is much as in the type.
