The new genus, Leipanthura, could be identified in a first couplet of a key to genera of Anthuridae as follows:

1 Uropodal exopod terminal, cylindrical...................................... Leipanthura

– Uropodal exopod subterminal, dorsal, leaf-like .... all other genera (see key in Poore, 2001)

Alternatively, it would be necessary to replace the final couplets of Poore’s (2001:

105) key to genera of Anthuridae to accommodate Leipanthura as follows:

22 Mandibular palp of 3 articles .................................................................... 23

– Mandibular palp of 1 article ..................................................................... 24

23 Uropodal exopod terminal, cylindrical...................................... Leipanthura

– Uropodal exopod subterminal, dorsal, leaf-like ............................... Anthura

24 Pereopod 7 present..................................................................... Ptilanthura

– Pereopod 7 absent................................................................... Exallanthura
