(Harpacticoida: Ancorabolidae) was found in meiofauna samples taken off Sinaloa (North-western Mexico) at a depth of 1985 m. Parsimony analysis of the <i>Ancorabolus</i>-lineage including this new species, confirmed Conroy-Dalton & Huys' (2000) conclusions on the monophyly of <i>Ancorabolus</i> and the validity of both <i>Breviconia</i> and <i>Juxtaramia</i>, and identified the Scandinavian <i>Ancorabolus confusus</i> as the closest relative of <i>A. hendrickxi</i> sp. nov. Both species show close similarity in the general body shape, length and pattern of integumental processes on the cephalothorax and body somites, elongate and slender caudal rami, absence of proximal recurved process on posterior margin of second antennulary segment and presence of an inner seta on the second endopodal segment of the second swimming leg. <i>Ancorabolus hendrickxi</i> sp. nov. can be readily differentiated from its congeners by the complete lack of a maxillulary coxal endite, the mandibular palp with five setae, and the very reduced proximal endite of the maxillary syncoxa bearing only one seta. Re-evaluation of the taxonomic status of the recently described species <i>A. ilvae</i> from the Magellan Straits, Chile demonstrates that it can only be regarded as <i>species inquirenda</i> in <i>Ancorabolus</i>. An updated generic diagnosis of <i>Ancorabolus</i> is provided. Postembryonic caudal ramus development within oligoarthran harpacticoids is analysed, based on observations of <i>A. confusus, Macrosetella gracilis</i> and <i>Microarthridion</i> sp., and additional literature data. A generalized developmental pattern of caudal rami, based on vertical tracking of the homologyof caudal setae I-VII throughout ontogeny is proposed.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Description of <i>Ancorabolus hendrickxi</i> sp. nov.
