Figures

Plate 1 issued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.238, Fig.20].
Female: a, forehead (dorsal, rostrum underneath); b, forehead (lateral); c, urosome (dorsal); d, idem (lateral left side); e, A2; f, Md (mandibular palp); g, Mx1; h, Mxp; i, P1; j, P5.
Nota: The urosome segments and furca are in the proportional lengths as 59:10:11:20 = 100. Prosome and urosome are in the proportional lengths as 78:22. A1 extends beyond the furca by 5 segments.
