Ref.:
Bradford-Grieve, 2001 (p.423, figs.F,M); Ferrari & Markhaseva, 2005 (p.46: tab.1)
Species Tharybis inaequalis - Plate 1 of morphological figuresissued from : J.M. Bradford in N.Z. Jl Mar. Freshw. Res., 2001, 35. [p.424, Fig.3].
Female (from SE North Island, New Zealand): A, habitus (dorsal); B, idem (lateral left side); C, idem of a distended specimen; D, E, rostrum (anterior view); F, urosome (lateral left side); G, idem (dorsal); H, genital complex (ventral).Nota: Head and 1st thoracic segment partially separate on dorsal surface, 4th and 5th fused. Urosome of 4 free segments (anal segment very small)A1 24-segmented


Species Tharybis inaequalis - Plate 2 of morphological figuresissued from : J.M. Bradford in N.Z. Jl Mar. Freshw. Res., 2001, 35. [p.426, Fig.4].
Female (from SE North Island, New Zealand): A, A1; B, A2; C, coxa of A2 (other side); D, Md; E, Mx1; F, Mx2; G, diagram of arrangment of bases of sensory setae of terminal part of Mx2; H, Mxp.


Species Tharybis inaequalis - Plate 3 of morphological figuresissued from : J.M. Bradford in N.Z. Jl Mar. Freshw. Res., 2001, 35. [p.427, Fig.5].
Female (from SE North Island, New Zealand): A, P1 (posterior view); B, P1 (endopod antero, anterior); C, P2 (posterior); D, P3 (posterior); E, P4 (anterior); F, P4 (exopod segments 2 and 3 , posterior view); G, P5 (anterior).
Nota: Segment 3 of exopod of P4 appeared to be deformed as the proximal outer edge spines were close together and the general appearance of the segment differed from that of female P3 and male P4.


Species Tharybis inaequalis - Plate 4 of morphological figuresissued from : J.M. Bradford in N.Z. Jl Mar. Freshw. Res., 2001, 35. [p.428, Fig.6].
Male (from SE North Island, New Zealand): A, habitus (lateral right side); B, idem (dorsal); C, posterior urosome (ventral); D, P5 (anterior, left exopod segments 1 and 2 collapsed); E, P5 (from left side); F, left exopod of P5; G, detail of left exopod of D.

Nota: head and 1st thoracic segment incompletely separated, 4th and 5th fused. Urosome of 5 free segments (anal segment very small). P5: uniramous, asymmetrical (slightly longer on left)


Species Tharybis inaequalis - Plate 5 of morphological figuresissued from : J.M. Bradford in N.Z. Jl Mar. Freshw. Res., 2001, 35. [p.429, Fig.7].
Male (from SE North Island, New Zealand): A, right A1; B, terminal segments of left A1 (segments XXII and XXIII are separated); C, A2; D, Md; E, Mx1; F, Mx2; G, diagram of arrangement of bases of sensory setae of terminal part of Mx2.


Species Tharybis inaequalis - Plate 6 of morphological figuresissued from : J.M. Bradford in N.Z. Jl Mar. Freshw. Res., 2001, 35. [p.431, Fig.8].
Male (from SE North Island, New Zealand): A, Mxp; B, P1 (anterior view); C, P2 (posterior); D, P3 (posterior); E, P4 (posterior).

Distribution map of Tharybis inaequalis by geographical zones
Loc:
New Zealand (off East Cape)
N: 1
Lg.:
(871) F: 0,9-1,21; M: 0,9; 1,12; { F: 0,9-1,21; M: 0,9-1,12}
Rem.: hyperbenthic (depths: 299 m).
According to Bradford-Grieve (2001, p.432) this species can distend its gut, thus altering the shape of the anterior body.
