Eyes relatively small to medium in size. Clypeus usually with a median longitudinal carina; anterior margin with several denticles. Maxillary palpi 1- to 5-segmented, labial palpi 3-segmented.

Remarks
|
|
Pristomyrmex comprises about 40 described species (Bolton, 1981): 5 Afrotropical (Bolton, 1981); 2 Madigascar (Brown, 1971); 6 Australian (Taylor, 1965, 1968b), and more than 20 in the Oriental Region and Melanesia. The Oriental fauna is not well understood taxonomically. Two species, P. pungens and P. yaeyamensis, have been recorded from Japan.
