New families and subfamilies of amphipod crustaceans
Cleonardopsis K.H. Barnard, 1916, has been incorrectly placed in the Eusiridae. Based on mouthpart morphology, body carination and the shape of the gnathopods it is reassigned to the Amathillopsidae in the new subfamily Cleonardopsinae. Cleonardopsinae is cosmopolitan in the deep sea. Parepimeria Ch...

A monotypic family, Miramarassidae, is established which may have affinities with iphimedioid taxa. Miramarassidae is currently known only from Cuba. Regalia K.H.

A fresh evaluation of the genus has shown that characters not considered by earlier workers, such as a callynophore on antenna 1, brush setae on antenna 2 and a straight, minutely serrate incisor on the mandible, indicate that Regalia cannot be a calliopiid or a pleustid. Regalia appears to be most similar to members of the Pardaliscidae, but a number of characters such as the lack of an accessory flagellum, the presence of a left and right lacinia mobilis, a well developed molar and lateral ridging on the pleosome exclude it from this family.

Sancho Stebbing, 1897, has most recently been placed in the Eusiridae (sensu lato), but might be more suited to the Calliopiidae (sensu stricto) because of its entire telson. Unlike eusirids or calliopiids, species of Sancho have a non-recessed head and a dorsoventrally flattened urosome. Sanchoidae is established as a new monotypic family for Sancho, currently known from shallow water in south-eastern Australia.
