Pliosity whitish-yellow, short and recumbent, densest on the tarsi. Antennal scape not reaching the vertex. Eyes of a single large, rounded facet, about one-sixth back from the mandibles. Clypeus slighty convex, with a vague median carina, anterior margin rectilinear. Mandibles slightly puncturated, with 4 large black teeth, subtended by 5 smaller yellow teeth.
Thorax profile almost flat.
Epinotum short, rounded with declivity flat, a little shorter than the dorsum, without marked lateral margins. Petiole scale remarkable in its great volume, equal to that of the epinotum, very high and thick. Epinotum angle more rounded than lea . Metanotal groove distinct. Now, the Bernard key still leads my specimen to this species, albeit with a lighter colour.
