The genus Pseudoxomysis (Crustacea: Mysidacea: Mysidae: Leptomysini), with description of a new species from the Timor Sea

摘要

Two species of Pseudoxomysis are discussed. The present occurrence of P. caudaensis in coastal waters of Indonesia is only the second record for the species since Nouvel established it based on specimens from Vietnam. A new species, Pseudoxomysis incisa, is described from the Sahul Shelf, Timor Sea. The new species is distinguished from the other species of the genus, P. caudaensis, by the smooth body, the third segment of the mandibular palp furnished with two series of setae on the outer margin, the endopod of the fourth male pleopod extending to the distal end of the fourth exopod segment, and the endopod of the uropod armed with 50 spines on the inner margin.
