Collected in July, several females had eggs.</p><p>Distribution</p><p>Reykjanes Ridge, south of Iceland, depth 644– 992 m.</p><p>Taxonomic remarks</p><p>There is a high variability in the dorsal carination. While the specimens belong to the same genetic haplotype, there are two morphotypes in respect of the sculpturing of pereonites and pleonites. Morphotype A is more robust, extensions start on pereonite 4 (Fig. 8), whereas morphotype B is smoother, the carinae starts on pereonite 7 (Fig. 13). Both morphotypes occur sympatrically, on the same coral. SEM photos of morphotype A are Figs 8–12, for morphotype B Figs 13–16.</p><p>Neopleustes schwentneri sp. nov. is generally morphologically closest to N. boecki (Hansen, 1888) . The main morphological differences between N. schwentneri and N. boecki are summarized in Table 2.</p><p>Genbank numbers for N. schwentneri sp. nov., as listed in Schwentner &amp; Lörz (2021) as Neopleustis aff boecki are: MT317424, MT317425, MT317427, MT317428, MT317432 – MT317452.
