Anarthruridae Lang, 1971 Diagnosis. See Larsen (2005). Remarks. The family is comprised of eleven genera including the one described here (Anderson 2014). Bird (2004) erected five new genera from the Northeast Atlantic and summarized the taxonomic history of the family. Since then two more genera have been established by Bamber & Błażewicz-Paszkowycz (2013) and Błażewicz- Paszkowycz et al (2013). Members of this family are distinguished from other families by, inter alia , having a short and round cephalothorax, weak mandibles, a cheliped with a large pseudocoxa ( sensu Sieg) and basis without a free posterior lobe, chela often with a lateral fold or distal protuberance, pereopods 1–3 with only setae on the merus and carpus, pereopods 4–6 generally with short claws (dactylus and unguis), and a non-articulated (fused) uropod exopod. Another character potentially uniting this family is the long seta attached to the base of the dactylus on pereopods 1–3; this accessory seta is present in many other groups but is particularly long in many anarthrurids. Only one anarthrurid species ( Anarthruropsis edentula Larsen, 2005) has been described from the Gulf of Mexico until now. Type genus. Anarthrura G.O. Sars, 1882. Other genera.
