Bregmatomyrma

Known from a few collections of single queens. Collection details include limestone forest and rainforest habitats.

Identification
The general habitus of the insect somewhat resembles that of Pseudolasius and suggests that it might be placed, for the present, near the tribe Lasiini.

Castes
Only known from the queen caste.
