Hemilamprops Sars 1883

Hemilamprops (?) bicarinatus Ledoyer, 1988

Hemilamprops (?) bicarinatus Ledoyer, 1988: 145–147, fig. 11A.

Type material. Deposition unknown. Mozambique Canal, 12°14’4”S, 46°41’6”E. Not seen.

Diagnosis. Carapace with 2 lateral ridges, without setae, dorsal crest with teeth. Telson 0.7 length of uropod peduncles, with 5–6 pairs lateral setae, 3 terminal setae. Uropod exopod unknown, broken. Adult male unknown.

Depth. 2500 m.

Distribution. Geyser Bank, off Madagascar, Indian Ocean, 12°14.4’S, 46°41’E.

Remarks. The description is based on two incomplete female specimens. The carapace sculpturing, which includes a marginal carina, suggests that Hemilamprops is not the correct genus, as does the reduced pereopod 5. However, without specimens that are more nearly complete, and perhaps the adult male, it is not possible to be definitive about the genus placement. Within Hemilamprops, the most similar species is H. bacescui from the Weddell Sea. The two species can be differentiated by the lateral setation on the telson. In H. bacescui there are three or fewer pairs of lateral setae on the telson, while in H. bicarinatus there are five or more pairs of lateral setae on the telson.
