On Pseudolamprops profundus (Reyss, 1978)

Gamô (1989a) stated that Lamprops profundus may be referable to the genus Pseudolamprops . Although Reyss’ (1978b) description is quite incomplete there is no doubt that this species belongs to Pseudolamprops because of the carapace spinulation, the rounded antero-lateral angle, the two subterminal setae on dorsum of the telson and, above all, for the short exopod uropod, which is unique in the family Lampropidae . Therefore, the new combination, Pseudolamprops profundus (Reyss, 1978) comb. nov., is proposed.

The type material of Lamprops profundus seems to be lost (Reyss, pers. comm.). According to Reyss’ (1978b) description and illustrations, L. profundus has an elongated pseudorostrum and the uropod exopod slightly longer than first article of the uropod endopod. By contrast, in the two adult specimens herein described the pseudorostrum is short and the uropod exopod distinctly shorter than the first article of the endopod. Apparently, Reyss (1978b) described and illustrated a juvenile female, and the differences above mentioned may be related to changes in the relative growth during ontogeny. In fact, the two juveniles examined in the present study have the pseudorostrum upturned and longer than in the adults, and the uropod exopod barely shorter than the first article of endopod. Hence, despite the fact that the adult specimens herein studied differ in the two above-mentioned characters from Reyss’ (1978b) description, we believe they belong to Pseudolamprops profundus .
