The name is chosen not only to honour the warmth of friendship and laughter, enjoyed in the winter sunshine in Łódź, Poland during the ISA SSKI Amphipod Workshop, but also the bringing to light and warmth from the cold abyssal depths of this new and interesting genus and species of lepechinellid.</p><p>Diagnosis.</p><p>As for the genus.</p><p>Description.</p><p>Based on holotype, immature, SMF 63355, 6.8 mm.</p><p>Body: (Figs 1, 2): heavily granulated and setose.

While Pseudolepechinella apricity sp. nov. is placed within the Lepechinellidae, it is worth noting some of the similarities with other taxa here. Bousfield and Kendall (1994) indicated there were internal subgroupings within the Lepechinellidae that might merit formal recognition, pointing to species which exhibit plesiomorphic (atylinid) character states, such as a lack of mid-dorsal teeth on three or more pereonal segments, coxae 1–4 weakly processiferous below, and the pereopod dactylus less markedly elongate (as is seen in Pseudolepechinella apricity sp. nov.) than in other lepechinellid species groups. Despite these plesiomorphies, Pseudolepechinella gen. nov. clearly belongs in the Lepechinellidae rather than the Atylidae, owing to the possession of a body cuticle covered in long spines and setae (vs lacking spines and setae), elongate, similar pereopods 5–7 (vs not elongate, dissimilar), styloid, elongate rami of uropod 3 (vs lanceolate, not elongate), and widely gaping telson lobes (vs closely appressed). In the same work, Bousfield and Kendall (1994) also moved the abyssal species Lepechinella aberrantis (J. L. Barnard, 1962) to the new genus Aberratylus Bousfield &amp; Kendall, 1994, within the Atylidae . There are strong similarities in the form of the pereopods between Pseudolepechinella gen nov. and Aberratylus, which may warrant further study of that family placement.</p><p>Distribution.</p><p>Abyssal Pacific Ocean, Clarion-Clipperton Zone, 4097–4275 m.</p><p>Molecular data.</p><p>Sequence data for the holotype of Pseudolepechinella apricity gen. nov. and sp. nov. is deposited in GenBank under accession number PQ 734583 (COI). Sequences of the paratype are deposited in GenBank with the following accession numbers: PV 077663 (COI), PV 077972 (16 S), and PV 078012 (H 3).

While characters of the gnathopods and pereopods are not indicated in previous diagnoses (or keys), these characters will need to be included in subsequent descriptions as increasing morphological variation within the family is being encountered. Pseudolepechinella gen. nov. can be distinguished from Lepechinella and all other genera within the family by the unusual shape of the propodus of gnathopods 1 and 2 (rounded / ovoid); the extremely elongate, slender carpus of gnathopod 2 (as long as basis and 4 × propodus), the short and more robust form of the pereopod 5–7 bases (length ~ 2 × width); and the distally expanded propodus with short, robust dactyls on pereopods 3–7. These characters are sufficient to differentiate the new species from all currently described lepechinellid genera and therefore the erection of a new genus for the species is warranted. There are no taxa that possess this combination of unusual gnathopod and pereopod characters within the Lepechinellidae . The majority of lepechinellids are characterised by slender, elongate pereopods, with elongate slender dactyls (length usually ≥ 0.5 × propodus, often subequal to or longer than the propodus), adaptations which are characteristic of amphipods living associated with soft abyssal sediments of the deep sea (J. L. Barnard 1973). The only exception within the family until now is that of the genus Lepesubchela, which has subchelate pereopods 6 and 7, suggestive of a clinging life strategy. In the genus Lepechinella, there are four species that have some similarities with Pseudolepechinella gen. nov. in the form of the shorter more robust pereopod bases: Lepechinella cachi J. L. Barnard, 1973; L. huacho J. L. Barnard, 1973; L. occlo J. L. Barnard; 1973; and L. pangola J. L. Barnard, 1962 . Of these species, Lepechinella occlo and Lepechinella pangola are most like Pseudolepechinella gen. nov. Lepechinella occlo is found in the Pacific, but at much shallower depths of 721 m off New Zealand, while L. pangola is found at abyssal depths of 4893 m in the Cape Basin, Atlantic Ocean. However, neither species possesses gnathopods similar to Pseudolepechinella gen. nov. and neither the basis broadening of pereopods 5–7 nor the distal expansion of the propodus of pereopod 3–7 are as strong as in the new genus.</p></div>	https://treatment.plazi.org/id/DED03DE0DDA1579F805B8C8495362CFD	Public Domain	No known copyright restrictions apply.
