Protanilla usually occur in well-developed forests but can sometimes be found along forest edges. They nest in rotten wood fragments and in soil (Vietnam, Eguchi et al 2014). In Borneo colonies, complete with dealate queens, were found in very rotten wood (one log, one partially buried stump) which were in an advanced stage of decay, the bulk of the colony being in the soil-wood layer immediately above the underlying clay soil.

Identification

Satria, Putri & Ahda (2023) - Characterized by its fully exposed antennal sockets in full-face view; clypeal disc trapezoidal, raised and flattened, and margined laterally with a sharp edge; inner surface of mandible with peg-like teeth; promesonotal suture present and flexible (Eguchi et al. 2014).

Biology

Cryptic and hypogeaic ants, it is unclear if they are rare or woefully undersampled. Myrmecologists have yet to implement adaquate techniques to sample the world's underground ant fauna. One recently discovery species, Protanilla beijingensis, was taken from a subterranean pitfall trap using a sampler that could prove useful for future surveys.
