Species Tortanus (Atortus) lophus - Plate 2 of morphological figuresissued from : T.E. Bowman in Pacif. Sc., 1971, XXV (4). [p.526, Fig.4 ].
Female: a, habitus (lateral); left side); b, urosome (lateral right side); c, process on left side of genital segment; d, process on right side of genital segment; e, urosome (dorsal); f, P5.
Nota: Genital segment with process on each side near ventral part of posterior margin; process of left side longer and tapering to sharper point than that of right side. A1 reaching caudal rami or slightly beyond. Legs as in T. scaphus except 1st endopod segment of legs 2-4 with patch of fine surface hairs on distal half of anterior surface near lateral margin. P5 only slightly curving inward, distal segment ending in 3 prongs, central prong about twice length of distal prong, proximal prong shorter than distal prong.

Male: g, habitus (lateral left side); h, urosome (dorsal); i, right A1 (ventral view); j, A1 (segment 17 and part of segment 18); k, A1 (junctute of segments 18 and 19-21); l, A1 (spinous process of segment 19-21); m, P5 (anterior); n, 1st endopod segment of P5 (anterior); o, idem (posterior)
