The Atlantic coast of Central and South America has been postulated as the most likely native range for <i>P. pusilla</i> (Mayer 1903; McCain 1968; Carlton and Eldredge 2009; Cabezas et al. 2019). Indeed, <i>P. pusilla</i> is one of the dominant species in natural sheltered and artificial habitats of the coasts of southern Brazil (Ros et al. 2016), adjacent to the coast of Uruguay. Therefore, it was expected that the species is also distributed along the Uruguayan coast. The material collected during the present study morphologically resembles <i>P. pusilla</i>, mainly in the presence of the anterolateral projection of pereonite 2 and the proximal knob on the basis of gnathopod 2. However, the anterolateral projection of pereonite 2 is very small in the material from Uruguay, and Uruguayan specimens lack the small dorsal tubercle on pereonite 2, which is present in <i>P. pusilla</i> (Ros and Guerra-García 2012; Ros et al. 2013 b). Gnathopod 2 and pleura of pereonites 3 and 4 also differ. Specimens from Uruguay are smaller than specimens of <i>P. pusilla</i> from other areas of the world. As specimens examined in the present study were mainly subadults, the morphological differences could be attributed to ontogenetic development. But we cannot exclude that the material of <i>Paracaprella</i> from this study could belong to an undescribed species, close to (but smaller than) <i>P. pusilla</i>. Collection of additional fresh material and further molecular and morphological analyses are encouraged to clarify the taxonomical status of <i>Paracaprella</i> in Uruguay.</p> |
