Plate 1 issued from : O. Tanaka in Proceedings Symposium on Crustacea. Symp. Ser. mar. biol. Ass. India, 1966 (2) 1. [p.48, Fig.6]. Female (from NW Kyushu, Japan): a, habitus (dorsal); b, forehead (lateral); c, last thoracic segment and urosome (lateral left side); d, last urosomal segments and furca; e, A1; f, A2; g, Md (mandibular palp); h, P1; i, P2; j, P3; k, endopod of P4; l, P5.
Nota: The urosome segments and furca are in the proportional lengths as 44:15:17:4:20= 100. Prosome and urosome are in the proportional lengths as 73:27. A1 not reacing the distal margin of the head.
Plate 2 issued from : O. Tanaka in Proceedings Symposium on Crustacea. Symp. Ser. mar. biol. Ass. India, 1966 (2) 1. [p.49, Fig.7]. Male: m, last thoracic segments and urosome (dorsal); n, A1; o, P5.
Nota: The urosome segments and furca are in the proportional lengths as 27:18:18:14:5:18 = 100. Prosome and urosome are in the proportional lengths as 70:30. The clasping A1 is on the right side. P5 is asymmetrical and resembles that of Pseudocyclops obtusus Brady & Robertson.
Distribution
NZ: 1 + 1 doubtful
Distribution map of Pseudocyclops australis by geographical zones
coastal. It is possible that two different species correspond to each of the two localisations. After Figueroa (2011, p.732) it is difficulut to ascertain if Nicholls' and Tanaka's specimens are conspecific due to lack of detail in Nicholls' description. There are key characters that are shared by P. australis Tanaka's specimens and P. juanibali, but also with differences.
