New Tanaidacea (Crustacea: Peracarida) from the Gulf of Guinea

Four new species of deep-sea Tanaidacea taken from the Gulf of Guinea as part of the Ghanaian marine environmental monitoring programme in 2012 are described. One of the species, which was classified to the family Anarthruridae, differed substantially from the other members of the family, and was accommodated to the newly erected genus – Olokun n. gen. Each of the three other species belongs to a different family: Parakanthophoreus guineus n. sp. – Akanthophoreidae, Collettea agnesi n. sp. – Colletteidae, and Araphura studens n. sp. – Tanaellidae. A key for genera of Anarthruridae is given.

First record of Tanaidacea (Crustacea) from a deep-sea coral reef in the Gulf of Guinea

Four undescribed species of Tanaidacea were discovered during a baseline monitoring program conducted off the coast of Ghana. The specimens came from a deep-water reef largely composed of the ahermatypic coral, Lophelia pertusa. The tanaidacean material was collected during November 2012 onboard the RV Dr Fridtjof Nansen using a van Veen grab in depths of between 375 and 386 m. Three of the new species described herein are tanaidomorphans belonging to the genera Bathyleptochelia (Leptocheliidae), Pseudotanais (Pseudotanaidae) and Cryptocopoides (Cryptocopidae). The fourth species, an apseudomorphan, belongs to Calozodion (Metapseudidae), a genus hitherto known only from shallow waters (<200 m). This report constitutes the first records of tanaidaceans from a deep-sea Lophelia reef.

Taxonomic etymology - in search of inspiration

Abstract We present a review of the etymology of zoological taxonomic names with emphasis on the most unusual examples. The names were divided into several categories, starting from the most common – given after morphological features – through inspiration from mythology, legends, and classic literature but also from fictional and nonfictional pop-culture characters (e.g., music, movies or cartoons), science, and politics. A separate category includes zoological names created using word-play and figures of speech such as tautonyms, acronyms, anagrams, and palindromes. Our intention was to give an overview of possibilities of how and where taxonomists can find the inspirations that will be consistent with the ICZN rules and generate more detail afterthought about the naming process itself, the meaningful character of naming, as well as the recognition and understanding of names.

A new genus of family Akanthophoreidae and new species of genus Parakanthophoreus Larsen & Araújo-Silva, 2014 (Crustacea: Tanaidacea: Tanaidomorpha) from the North Atlantic

Based on tanaidacean material collected primarily during the IceAGE cruises in the North Atlantic, three new species from the family Akanthophoreidae are described; one is classified in the genus Parakanthophoreus, and the other two represent a new genus—Brixia n. gen. The main characters that distinguish Brixia n. gen. from other akanthophoreids is the lack of fully developed pleopods in adult females and a seven-articled antenna. The diagnosis of the family Akanthophoreidae is amended. Cheliped ornamentation of Parakanthophoreus catharina n. sp. is illustrated using SEM pictures.
