Crematogaster monocula

This species is known from two workers collected from a lowland forest by Winkler extraction of leaf litter. It is only known from the type locality in Cambodia.

Identification
Crematogaster monocula is a member of the C. biroi group of the subgenus Orthocrema and shares all the group-specific characters (HOSOISHI & OGATA 2016). This species is well distinguished from all other Asian species of this species group by having one ommatidium and a relatively short scape (SI 64–66). Crematogaster monocula is similar to Crematogaster masukoi, but can be distinguished by having only one ommatidium, almost straight anterior clypeal margin and sculptured petiole.
