| Abstract |
The genus Ogyrides Stebbing, 1914 comprises 12 recognized species of small marine shrimps distributed in tropical and temperate waters worldwide. Ogyrides occidentalis (Ortmann, 1893), described for Brazil, was considered a junior synonym of Ogyrides alphaerostris (Kingsley, 1880). The aim of this study was to revalidate O. occidentalis from the Brazilian coast based on morphological and molecular data (16S gene), and to provide a redescription, illustrations and a comparison with congeners. As expected, O. occidentalis is close to O. alphaerostris but can be separated by molecular data, the proportional size of the second article of the antennular peduncle in relation to the third article (3–4 times as long as the former, and 2–2.5 times as long as the latter), and the size of the scaphocerite (not reaching the distal part of the second article of the antennular peduncle in O. occidentalis, while always reaching or sometimes overreaching the distal part of the second article of the antennular peduncle in O. alphaerostris). We also provided a table comparing key morphological characteristics of all known species of the genus, and discuss the validity of thelycum-like characters in the taxonomy of Ogyrides |
