Cyzicus (Estheria) rufa Dakin, 1914

Cyzicus (Estheria) rufa Dakin, 1914: 295 (list), 301–302, pl. 2, figs. 19–21.

Type material. None designated.

Remarks. Using the description by Dakin (1914) of two females, whether this species belongs to Caenestheria or Caenestheriella is uncertain. According to Brtek (1997), it is conspecific with Caenestheria sarsii ( Sayce, 1903) , which he calls Eocyzicus sarsii ( Sayce, 1903) , a possibility that was discussed by Dakin (1914) but rejected. Its rostral characteristic of lacking a posterior margin shows it is neither Eocyzicus or Cyzicus .

Distribution. Pools at Lakeside, Boulder City (Western Australia).

Limnadiidae Baird, 1849

Limnadiidae Baird, 1849 .

Limnadiidae in Simon, 1886, in part.

Spinicaudata with valves rounded, often thin and transparent, with growth lines in the peripheral zone only (except in Limnadopsis ). Umbo absent or weakly developed. Head with a pear-shaped organ behind the eye. First three pairs of limbs of both sexes with an endopodial palp. Limbs 9 and 10 of female with ovigerous flagellum.

Seven species of Limnadia and two of Eulimnadia are described from Australia. The genus Limnadopsis Spencer & Hall, 1896 can be distinguished from the genus Limnadia by growth lines that cover the entire carapace and by the absence of the typical sucker-like projection on the movable fingers of the male claspers. Limnadia is distinguished from Eulimnadia by the absence of the spine on the lower distal angle of the telson. The status of Limnadopsis is confused. Novojilov (1958) erected a new genus, Limnadiopsium for Limnadopsis tatei , and a new family, the Limnadopseidae , for both genera. This approach has been accepted by Naganawa (2001). Dumont & Negrea (2002) place this group as a subfamily Limnadopsinae within the Limnadiidae , while Martin & Davis (2001) do not recognize either family or subfamily rank for this group. We follow Martin & Davis, but recognize the problem is not resolved. We see no reason for the transfer of Limnadoposis tatei to a different genus, Limnadiopsium (see Brtek, 1997). Limnadopsis is endemic to Australia, with four described species.
