| | | | | | Syn.: | Disseta minuta Grice & Hulsemann, 1965 (p.224, 245, figs.F,M); 1967 (p.18); Park, 1970 (p.477) | | | Ref.: | | | Heptner, 1972 a (p.60); Park, 2000 (p.7, Rem.); Vives & Shmeleva, 2007 (p.321, figs.F,M, Rem.) | issued from : G.D. Grice & K. Hulsemann in J. Zool., 1965, 146. [p.246, Fig.17]. As Disseta minuta. Female (from 29°57''- 40°03'N, 22°58'-19°57'W): a, habitus (dorsal); b, urosome (dorsal); c, distal part of metasome and urosome (lateral left side); d, rostrum (lateral); e, idem (frontal view); f, Md (mandibular palp); g, Md (cutting edge); h, Mx1; i, Mx2; j, Mxp; k, P1. Nota: - Head and 1st thoracic segment separate, 4th and 5th fused. - Caudal rami asymmetrical, left one longer than the right. - P5 present but broken off distally. - Genital somite symmetrical, greatly protruded ventrally. Male: l, anal segment and furca; m, geniculate part of left A1; n, right P5; o, left P5. Nota: Rostral fimlaments not observede. - Left A1 geniculate, segment 18 with small lamella; segments 19, 20 and 21 fused with invagination on proximal part of segment 19. - 2nd basal segment of P5 without protrusions or lamella. Exopods 3-segmented; right endopod 2-segmented, left endopod 3-segmented. Distal sdegment of right exopod with long curved seta and 1 spine-like protrusion; distal segment of left exopod with 3 straight and unequal setae.

For Grice & Hulsemann the discovery of female specimens with intact P5, as the male P5 differ in some details from those of Disseta, may require the erection of a new genus. | | | Last update : 18/10/2017 | |
