Eulimnadia and Paralimnadia are both strongly
supported, monophyletic limnadiid lineages based on molecular studies.
However, defining the two taxa morphologically relies on the
presence/absence of a subcercopodal spiniform projection; otherwise
there is considerable overlap and confusion in morphological characters
between the two taxa. The most discriminatory of these characters are
examined here and applied to Australasian species. As a result, five Eulimnadia species are transferred
to Paralimnadia. These
characters are then applied to world Eulimnadia
species and other limnadiid genera which share key features with Eulimnadia.
Key words: Clam shrimp,
Cercopods, Antennomeres, Claspers, Amplexus, Reproductive systems.
