LaPolla & Cheng, 2010
Paraparatrechina oreias has been collected from montane rainforest.
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.

Scapes surpass posterior margin by about the length of the first 2 funicular segments; scapes with appressed pubescence. Mesosoma compact, yellow to slightly brownish-yellow laterally; fine pubescence covers dorsum. Pronotum rises very steeply from anterior margin to dorsum. Mesonotal area distinct, with prominent mesonotal spiracles. Propodeum possesses a short, angular dorsal face, with a long declivitous face.
