Specimen labels

Little is know about this species. The type series was collected in oak leaf litter. A second collection was made from a rotten log in a riparian woodland bordering a lake.


Prebus 2017 - A member of the andrei clade.

Mackay (2000) - This is a small, light brown species with a 12-segmented antenna, in which the apex of the petiolar node is very sharp. The dorsum of the head is punctate and striate, except for a central strip, which is smooth and shining. The mesosoma, petiole and postpetiole are completely punctate, with a few rugulae on the dorsum of the mesosoma.

This species is closely related to Temnothorax mariposa (=nitens), differing in that most of the head is sculptured, whereas the head of Temnothorax mariposa is nearly entirely smooth and shining.
