Abstract
A new family of haustorioid Amphipoda resembling the Phoxocephalopsidae and Urothoidae has been discovered in sands of the surf zone off Rio de Janeiro, Brazil. Like the recently described Cheidae, the new speciesgenus- family combines various characters of haustorioids in a unique manner and bears one unprecedented apomorphic character: an alate, uncleft telson.
The new taxon has the following characters of Urothoidae: antenna 2, head, and distal parts of pereopods but has a distinctive antenna I, coxae 1-2, mandibular palp, telson and epimera 1-2. Ipanema has the following characters of Phoxocephalopsidae: coxae, mandibles, and uropod I but has distinctive antennae 1-2, epimera 2-3, pereopods 5-7 and telson. The taxon has some characters found mostly or only in Urohaustoriidae, such as epimera 2-3, but differs in many ways from that family, such as: head, antennae 1-2, parts of mandibles and maxillipeds, maxilla I, parts of pereopods 3-7, epimeron I, and especially uropods 1-2.
