Planche 1 issued from : S. Ohtsuka & D.V.P. Conway in J. Mar. Biol. Ass. U.K., 2003, 83. [p.357, Fig.2].
Female (from Rodrigues Island, Mauritius): A, habitus (dorsal); B, idem (lateral left side); C, urosome (lateral left side); D, left lateral swelling of genital compound somite; E, urosome (lateral right side); F, idem (dorsal); G, idem (ventral); H, syncoxa of Mxp; I, P5 (anterior); J, right exopod of P5 (anterior); K, left exopod of P5 (anterior).
Scales in mm.
Nota: Head and 1st thoracic segment separate, 4th and 5th fused. P5 slightly asymmetrical (right leg longer than left), 1-segmented exopod bearing 1 inner and 2 terminal acutely pointed processes, outer terminal process slightly longer than inner process, with 2 minute pointed prominences an anterior surface (arrowed in Fig.2J,K). Urosome 2-segmented. Genital complex slightly asymmetrical, expanded anterolaterally on both sides, expansions each with peg-sensillum at tip (Fig.2C-E). Anal somite remarkably asymmetrical. Caudal rami considerably asymmetrical

Planche 2 issued from : S. Ohtsuka & D.V.P. Conway in J. Mar. Biol. Ass. U.K., 2003, 83. [p.358, Fig.3].
Male: A, habitus (dorsal); B, genital and 1st abdominal somites (lateral right side); C, right caudal ramus (dorsal); D, right geniculate A1 (segment XIX to compound segment XXIV-XXVIII); E, P5 (anterior); F, tip of right exopod of P5 (anterior, subterminal and terminal elements arrowed); G, right P5 (posterior, three minute coxal prominences arrowed); H, distal exopodal segment of left P5 (posterior).
Scales in mm.
Nota: Head and 1st thoracic segment separate, 4th and 5th fused. Urosome 5-segmented; 2nd urosomal segment with 2 posterolateral setules on right side (Fig.3B). Caudal rami, symmetrical, separate from anal somite. Right and left P5 with coxa unarmed; right basis bearing large inner bilobed process at mid-length; left basis with1 outer and 1 inner setule, exopod 2-segmented.

Planche 3 Issued from : S.V. Francis & S. Bijoy Nandan in Turkish J. Zool., 2019, 43. [p.434, Table 4].
Differential diagnosis of T. insularis female. Compare with other species of the subgenus Atortus species from the Indian Ocean.

Morphological characters female:
- Genital compound somite asymmetrical. Caudal rami slightly asymmetrical with left ramus stouter and shorter that the right one.

Planche 4 Issued from : S.V. Francis & S. Bijoy Nandan in Turkish J. Zool., 2019, 43. [p.435, Table 5].
Differential diagnosis of T. insularis male. Compare with other species of the subgenus Atortus species from the Indian Ocean.

Morphological characters male:
- Left P5 terminal portion of 2nd exopodal segment acutely pointed at tip, with serrated subdistal seta. Right P5 coxa bearing 3 acutely pointed prominences of unequal size, basis bearing large bilobed process at midlength.
