| Summary: | Tanaella Norman & Stebbing, 1886 Diagnosis (see Larsen 2005). Remarks. This genus currently comprises 17 species including the one described here. It is recognized by a large antennule article-2, pincer-like uniramous uropods that have much-reduced, vestigial, or absent, fused exopods and, like Collettea, females almost invariably lack pleopods (exceptions being Tanaella dongo Bamber, 2005, T. forcifera (Lang, 1968) and T. kommritzia Larsen & Shimomura, 2007). However, the last character is open to some confusion when assigning a sex to a particular specimen of Tanaella. Males (or at least sub-adult or “preparatory” males) can be distinguished with care by their slightly enlarged antennules compared to those of females. Ideally the presence of pleopods in females of this genus should be confirmed by their association with at least oostegite buds if not a complete marsupium. Tanaella was revised fairly recently (Larsen & Heard 2004), and since then new species have been discovered in the Antarctic ... : Published as part of Drumm, David T. & Bird, Graham J., 2016, New deep-sea Paratanaoidea (Crustacea: Peracarida: Tanaidacea) from the northeastern Gulf of Mexico, pp. 389-414 in Zootaxa 4154 (4) on pages 398-399, DOI: 10.11646/zootaxa.4154.4.2, http://zenodo.org/record/260424 ... |
