Nota: Mx2: 2nd seta of 1st lobe less than 1/2 length of 1st spine; spine of 2nd lobe relatively thin; posterior subterminal spine of 4th lobe 40% as long as 2nd saberlike spine; falcate spine of 5th lobe about 1.2 times length of saberlike spine, with about 1/2 of medial margin serrated with spinules: falcate spine of 6yj lobe with about 68% of medialmargin serrated with spinules.

[p.82, Fig.49]. Female: A, urosome (dorsal); B, genital somite (left lateral side); C, lobe 4 of Mx2. Male: D, P5 (L = left leg; R = right leg).

 issued from : O. Tanaka in Publs Seto Mar. Biol. Lab., 1964, XII (1). [p.5, Fig.176]. Female: a, habitus (dorsal); b, last thoracic segment and genital somite (lateral left side); c, idem (other specimen); d, idem (ventral); e, Mxp; f, curved spine on the 2nd basal segment of P1; g, P5. Nota: The urosome segments and furca are in the proportional lengths as 47:14:10:8:21 (right) = 100. The genital somite slightly asymmetrical.A1 exceeds the end of the furca by 2 terminal segments. Male: h, P5; i, urosome (dorsal). Nota: The urosome segments and furca are in the proportional lengths as 21:17:15:13:6:28 = 100. A1 exceeds the end of the furca by one terminal segment.

 Issued from : J.C. von Vaupel-Klein in Zool. Verh. Leiden, 1970, 110. [p.32, Fig.15,a-c]. Female: a, genital complex (lateral right side); b, left Md (chewing plate); c, right Md (chewing plate). Nota: The specimens shows differences in the structure of the chewing plates; Brodsky described the mandibles of the females as \"symmetrical, except for the number of teeth\". In our specimens the number of teeth is 2 on the left mandible and 3 on that of the right mandible. The caudal margins of the urosomal somites have serrated edges, but not mentioned by Brodsky (1950).
