| Summary: | Chalarostylis sp. A Material examined: POLYGAS. Sta. DS15, 47º35.2'N, 08º40.1'W, 2246 m, 21 Oct 1972: 10 specimens (MNHN- IU-2013-11345). Sta. DS18, 47º32.2'N, 08º44.9'W, 2138 m, 22 Oct 1972: 9 specimens (MNHN-IU-2013-11346). All these specimens are so badly damaged that an adequate description is not allowed. Despite that, this material alerts us about the presence of another species of Chalarostylis in the North-East Atlantic. A few remarks on this undescribed species are presented below. Only a subadult female from the POLYGAS Sta. DS15 has an entire first pereopod. Like in H. canadensis, the carpus and propodus of the first pereopod are armed with teeth (Fig. 4 B). However, this POLYGAS specimen differs from H. canadensis by having a larger merus (about as long as basis), and a shorter dactylus (about 1/3 as long as propodus) with 6 instead of 7 strong simple setae. The telson from all the POLYGAS specimens examined are armed with a medial distal seta distinctly stronger than the lateral ones (see Figs. ... : Published as part of Alberico, Natalia A., Roccatagliata, Daniel & Mühlenhardt-Siegel, Ute, 2014, Remarks on the deep-sea genus Chalarostylis (Cumacea: Lampropidae), pp. 323-334 in Zootaxa 3753 (4) on page 329, DOI: 10.11646/zootaxa.3753.4.2, http://zenodo.org/record/226665 ... |
