Diagnosis

( Wagner 1990): The carapace is broader than long, rather flat. Branchial sulci on its surface are not or very weakly broken by transverse grooves. Rostrum is little advanced, incised by a narrow notch. The basal antennal segment has two spines, of which the second, situated on the antero-external angle, is five times as large as the first. In small individuals, two acute tips can be observed distally on the second spine. The antennae are 0.2 times as long as the carapace. The orbit is armed with one spine below (not counting the basal antennal spines), one at the outer angle and three above (Fig. 9 e).
