Diagnosis

Differs from the last [Argeleusa] by the head being scarcely if at all produced before the eyes. The lateral keels of the vertex fork just before their middle, the outer forks diverging a trifle, the inner rounding gradually and meeting the median keel at the apical margin. Frons nearly as broad apically as long, narrowing a little towards the base. Tegmina granulate, apical third more or less declivous. (Kirkaldy 1906)

In his key to genera of Achilidae, Kirkaldy (1906) uses the following features: Tegmina granulate on the costal cell and sparsely elsewhere, veins stout and prominent, granulate; frons not banded; head not or very slightly produced in front of the eyes; vertex distinctly angulately emarginate.
