DESCRIPTION

Dorsal surface of carapace uniformly paved with minute rounded granules. Frontal lobes subtruncate, slightly sinuous. Hepatic region slightly tumid. Anterolateral margins medially constricted. Epibranchial lobe convex, prominent; margin prominently lamellate. Intestinal region inflated, prominent, laterally demarked by shallow grooves. Posterior margin lamellar. Anterior margin of efferent branchial channel narrowly slit medially. Third maxilliped minutely granulate. Chelipeds minutely granulate; merus in adult male about 1.5 as long as carapace; fingers about half as long as propodus. Lower margin of propodus of first pereiopod granulate. Abdominal sternites, somites closely set with minute granules. Subdistal denticle on fused male abdominal segment prominent, medially sulcate. Male first pleopod slightly curved, distally with few marginal setae; second pleopod sinuous, distally curved.

REMARKS

Zarenkov’s (1994) description and illustrations of Praebebalia elata emphasize the lamellate lateral margins of the carapace, as well as the prominent intestinal region, the keeled pterygostomian margin, the basio-lateral protuberances on fused male abdominal segment, and the shape of the first and second male pleopods. These findings greatly increase the known range of the species.
