 issued from : K. Schulz in Mitt. hamb. zool. Mus. Inst., 1990, 87. [p.184, Fig.2]. Male: A, habitus (dorsal); B, cephalosome (dorsal); C, idem (lateral left side); D, caudal rami (ventral); E, left A1; F, right A1 (segments 19 to 22; G, Md. Nota: Rostrum absent, but 2 small filaments. - Anterior part of cephalosome with dorsal hump and, in region of Md region, sudden transversal cleft, accompanied by bilateral-symmetrical processes (lobe-like structures usually reinforced inside by cone-shaped chitinous process; tips of these structures appear to be broken). - Dorsal body wall of 1st pedigerous somite equipped with bilateral-symmetrical prominence producing bulbous swelling on either side of midline, both equipped anteriorly with small fingered appendix. In lateral view bulbous swelling transparent. - 2nd pediger somite dorso-distally furnished with row of strong bristles, and 2 long spinules anterodorsal of row of bristles. - Genital aperture located on left side of 1st urosomal somite. - Anal somite very short (almost completely telescoped into prceding one. - Caudal rami bearing 1 short outer seta and 4 setae terminally (2nd to innermost seta longest, about 2.0 mm), small appendicular seta arising from ventral surface. - Md without mandibular blade, exopod longer than endopod. - A1 with incomplete fusion of segments 9-10 and 12-13, and complete fusion of segments 24-25; segments 20-21 are fused on the right but separate on the left.

Mx2 greatly reduced in size and setation, proximal lobe 1 without seta, lobes 2 to 6 with 1, 2, 2, 2, 1 setae, respectively; endopod with ca 3 setae. Right exopod of P5 very long, extending as far as caudal ramus
