Paraparatrechina oreias

Paraparatrechina oreias has been collected from montane rainforest.

Identification
LaPolla et al. (2010) - Metanotal area distinct, with raised metanotal spiracles; head and scapes with appressed pubescence.

Compare with: Paraparatrechina gnoma and Paraparatrechina subtilis. The layer of appressed pubescence covering the head and scapes effectively separates this species from P. subtilis, the species most likely to be confused with P. oreias.
