description: Eriopisidae fam. nov.
Type genus. Eriopisa Stebbing, 1890.
Diagnostic description. Body laterally compressed, subcylindrical or vermiform. Eyes well developed, poorly developed or absent, if present then round or ovoid. Antennae 1–2 calceoli absent. Antenna 1 longer than antenna 2; peduncular article 1 shorter than, subequal to, or longer than article 2; article 2 longer than article 3; article 3 shorter than article 1; peduncular articles 1–2 not geniculate; accessory flagellum short or minute. Antenna 2 peduncular article 1 not enlarged. Mandible molar triturative; palp symmetrical. Maxilla 1 basal endite setose along medial margin; palps symmetrical. Maxilla 2 basal endite with oblique setal row. Labium inner lobes present. Coxal gills [not known]; sternal gills absent; sternal blisters absent; oostegites fringing setae simple. Gnathopod 1 subchelate; smaller (or weaker) than or similar in size to gnathopod 2; propodus palm without robust setae along palmar margin. Gnathopod 2 subchelate; similar in males and females (not sexually dimorphic); carpus not produced along posterior margin of propodus, projecting between merus and propodus. Pereopods 3–4 not sexually dimorphic. Pereopod 4 without posteroventral lobe. Pereopod 5 shorter than pereopod 6; coxa with posterodorsal lobe or with large anteroventral lobe or without lobes. Pereopod 7 longer than pereopod 5. Pleonites 1–3 without dorsal carinae. Urosomites 1–3 free; without slender or robust dorsal setae. Urosomite 1 without large distoventral robust seta. Urosomite 2 without dorsal setae. Uropod 1 with or without basofacial robust setae. Uropod 3 not sexually dimorphic; biramous, without plumose setae; endopod minute or shorter than exopod. Telson deeply cleft; dorsal or lateral robust setae present or absent; apical robust setae present.
Habitat. Marine, epigean and hypogean.
Included genera. The Eriopisa group includes 9 genera: Confodiopisa Karaman, 1984c; Eriopisa Stebbing, 1890; Flagitopisa Karaman, 1984c; Impertiopisa Karaman, 1984c; Nedsia Barnard & Williams, 1995; Psammogammarus S. Karaman 1955; Tunisopisa Stock, 1980; Victoriopisa Karaman & Barnard, 1979; Vo c it op is a Karaman, 1984c.
The Eriopisella group includes 12 genera: Cephalopisella G. Karaman, 1984c; Cuneimelita Senna & Serejo, 2012; Eriopisella Chevreux, 1920; Gammaropisa Ruffo & Vigna-Taglianti, 1988; Madapisella Stock, 1980; Maleriopa Barnard & Karaman, 1982; Netamelita J.L. Barnard, 1962; Nippopisella Stock, 1980; Norcapensis Bradbury & Williams, 1997; Psammomelita Vonk, 1988; Spiniferopisella G. Karaman, 1984c; Tagua Lowry & Fenwick, 1983.
Remarks. Roropisa Karaman, 1984c, which would fall into the Eriopisa group is considered to be a subjective synonym of Victoriopisa by Morino (1991) and Stock & Iliffe (1995).
The only difference between the Eriopisa and Eriopisella groups appears to be the extraordinarily well developed second article of the outer ramus of uropod 3 in the Eriopisella group. Eriopisids differ from maerids and melitids in the second gnathopods which are similar between males and females. Melitids are mate-guarders in which the male gnathopod 2 is enlarged. Pereopod 4 coxa is larger than that of pereopod 3 in melitids. Distribution. Cosmopolitan.
