Captured in wet forests, including montane areas. A millipede feeder.
Identification
A member of the rastrata complex (in the rastrata subgroup of the rastrata species group). Antennal scapes surpass vertexal margin by no more than their apical width; triangular and edentate mandibles with a varying degree of costulate and rugae; small tubercle-like propodeal teeth next to conspicuous spiracles which are slightly elevated above rest of surrounding cuticle; postpetiolar sternum with median longitudinal smooth and shining areas. The sculpture on the node as seen dorsally can vary from concentric costulae, with transverse or longitudinal costulae in the middle, or completely transverse. The petiolar node can be wider than long or the opposite. Size range is HL 0.74-0.90; WL 1.10-1.28 mm. (Lattke 1995)
