Abstract
A new species of the genus Liropus Mayer (Caprellidae) is described based on material collected from the middle mesophotic zone of southern Bahía de Banderas, Jalisco, Mexico. Specimens were found associated with gorgonians and sponges from a vertical rocky wall at 60-70 m depth. The new species, Liropus tenebrissp. nov., can be distinguished from all its congeners mainly by a head without projections; eyes present but not clearly distinguishable; antenna 1 flagellum five-articulate; antenna 2 flagellum two-articulate; body dorsally smooth; pereonite 2 with a pair of anterolateral projections in males; gnathopod 2 basis slightly curved, smooth as long as pereonite 2; pereopods 3 and 4 one-articulate; pereopod 5 two-articulate; abdomen without appendages in males. This is the fourth species of Liropus recorded in the Mexican Pacific and the Eastern Pacific.
期刊介绍：
Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
