Max. 5arum articuli secundi paralleli, medio in longitudinem sulcati, apice truncati; articuli tertii dilatati, margine superiore emarginati; articuli apicales abbreviati1).

In feminis oblongo-ovatum, a basi latescens; articulus sextus quinto duplo latior; septimus rotundatus. O c u l i vix tertia parte latitudinis thoracis distantes. Antennae oculorum canthis approximatae, flagello brevissimo.
