The majority of species has been recorded from relatively deep waters and the Southern Hemisphere. To date, 36 species have been described in the family belonging to three genera: <jats:italic>Ianthopsis<\/jats:italic> Beddard, 1886; <jats:italic>Iolanthe<\/jats:italic> Beddard, 1886; and <jats:italic>Mexicope<\/jats:italic> Hooker, 1985.<\/jats:p>\n          <jats:p>Here, a new species of <jats:italic>Mexicope<\/jats:italic> is described from Maltese waters, adding a fourth species to the genus. It is the first member of the family reported from the Mediterranean Sea. The new species can be recognised by the unique combination of the following characters: cephalothorax with pre-ocular spine large and pointed anterolaterally, rostral projection blunt, eyes reduced; pereonal sternites each with one ventral spine; pereonite two lateral margins with single projection; pleotelson posterior apex long, projecting to approximately half of the length of the uropod protopod; pleopods I distolateral lobes projecting beyond distomedial lobes, apices curved and pointed laterally; uropod exopod length approximately 0.5 endopod length. An identification key to the species of <jats:italic>Mexicope<\/jats:italic> is presented and the generic diagnoses of <jats:italic>Ianthopsis<\/jats:italic> and <jats:italic>Mexicope<\/jats:italic> are compared, discussed and revised.<\/jats:p>","DOI":"10.3897\/bdj.12.e121508","type":"journal-article","created":{"date-parts":[[2024,5,21]],"date-time":"2024-05-21T07:15:14Z","timestamp":1716275714000},"source":"Crossref","is-referenced-by-count":0,"title":["A new species of Mexicope Hooker, 1985 (Crustacea, Isopoda) \u2014 the first record of Acanthaspidiidae Menzies, 1962 from the Mediterranean Sea"],"prefix":"10.3897","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7363-4421","authenticated-orcid":true,"given":"Torben","family":"Riehl","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katharina","family":"Schienbein","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-1318-9416","authenticated-orcid":true,"given":"Constantine","family":"Mifsud","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2024,5,21]]},"reference":[{"key":"121508_B11370511","first-page":"1","article-title":"Report on the Isopoda collected by HMS Challenger during the years 1873\u201376.
