Abstract

The glass shrimps belonging to genus Pasiphaea are scarcely registered in Chilean waters, with just 5 of the 66 species recognized today. Of these Pasiphaea acutifrons is reported erroneously to some localities in different oceans, this due basically to an ambiguous diagnosis. Recently, a paper was published that analyze the taxonomic status of this species, limiting the range of variability of its diagnostic characters and restricting its distribution. In Chile P. acutifrons is distributed from Iquique to Magellan Strait, but the informed diagnostic characters are not in agree with those of this specie. By this reason is proposed a study to analyze the material referred as P. acutifrons with the object verify the status of this species in Chile. To this end, the material of Pasiphaeidae of 3 important carcinological collections in this country were revised, as well as new material collected in the CIMAR XIV expedition. The results of this study reveals that the specimens of P. acutifrons in fact belong to other species. One of these is Pasiphaea barnardi which is reported here by first time for Chilean Fjord, between Golfo de Penas and Concepcion Channel.
