Scale bars = 0.100 mm.
Nota: Cephalosome and pediger 1 weakly separated dorsally, more or less ventrolaterally, 4th and 5th pedigers fused.
- Posterior corner of prosome lobate and rounded, covering half of genital double-somite laterally.
- Urosome short, ratio of prosome to urosome length 3.7 : 1.
- In dorsal view genital double-somite with shallow lateral indentation on both left and right side.
- Anal somite a very short and narrow ring, especially dorsally, and almost completely telescoped into preceding somite.
- Caudal rami slightly longer than wide, bearing 1 ventral seta and 4 terminal setae.
- A1 24-segmented, reaching slightly beyond 2nd pedigerous somite.
- A2 segmentation and armature similar to those of T. angularis except for: the larger of the two basal setae only about half length of 1st endopod segment, and exopod being slightly less than twice length of endopod..
-Md coxa with strong gnathobase bearing molariform teeth complex ventrally and a number of setiform teeth dorsally covered by numerous spinules both anteriorly and posteriorly; basis armed with 2 curved spiniform setae and 1 long straigth subdistally implanted seta; endopod slightly longer than exopod, bearing 9 terminal setae; exopod 5-segmented, carrying 6 setae.
- Mx1 armature like that of T. angularis except distal basal endite with 2 setae..

Planche 2 issued from : Schulz & Beckmann, 1995, 80. [p.209, Fig.6]. As Tharybis crenata.
Female: A, Mx2; B, Mx2 (endopod); C, Mxp; D, P1; E, P2; F, P3; G, P4; H, P5.
Nota: Mx2 with endopod carrying 6 brush-like filaments proximally and 3 longer worm-like filaments distally. Praecoxa with distinct outer hump, praecoxal and coxal endites bearing 4, 3, 3, and 3 setae; endite of basis with 4 setae.
- Mxppraecoxal and coxal endites equipped with 1, 2, 3, and 3 setae from proximal to distal, the medial endite bears 1 aesthetasc-like spinulose seta terminating in a brush-like tip; endopod 6-segmented bearing 2, 4, 4, 3, 3+1, and 4 setae.
- P5 uniramous, 3-segmented and extending to distal margin of 2nd urosomal somite; coxae fused to form common base; endopod lacking; exopod less than twice length of basis, terminating in 2 pointed processes and 1 robust inner edge spine, all bearing marginal denticles. Ratio of lengths of outer and median processes and inner spine roughly 1 : 2 : 3.
