Species Microdisseta minuta - Plate 1 of morphological figuresissued 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.
