- Pseudopallene Arango, Claudia P., 2013, Zootaxa 3616: 411-415.
Australian Pseudopallene species—including those reported herein—differ from the type species P. circularis collected from the fjord of Scotland’s Forth River (Firth of Forth), in the ventralized position of the proboscis, which is in some species tapering, and the mostly glabrous body and legs. On the other hand, they share the massive cheliphores, the sometimes irregular, knobby fingers, and some degree of neck constriction (Goodsir 1842; Hedgpeth 1948). A comparison of colouration and some diagnostic characters among species proposed here and other South-Australian Pseudopallene species is presented in Table 3.
