Abstract

In Chile, amphipods of the genus Parhyalella Kunkel, 1910 (Amphipoda, Talitroidea, Dogielinotidae) have been assigned to Parhyalella ruffoi Lazo-Wasem and Gable, 2001 and recently have been used in macroalgal ecology studies. We show, however that these specimens belong to an undescribed species, that we describe herein as Parhyalella penai n. sp. This new species is characterised by a 4-conjointed article 1 of flagellum of antenna 1, bifurcate dactyl of gnathopod 1, width of article 6 of gnathopod 2 around 70% of its length and the presence of two distal spines in the peduncle of uropod 3. A new key to the genus Parhyalella is given. Copyright © 2008 Magnolia Press.
