Species Haloptilus chierchiae - Plate 1 of morphological figuresIssued from : G.O. Sars in Résult. Camp. Scient. Prince Albert I, 69, pls.1-127 (1924). [Pl., figs.1-13].
Female: 1, habitus (dorsal); 2, idem (lateral left side); 3, A1; 4, A2; 5, Md; 6, Md (biting blade, enlarged); 7, Mx1; 8, Mx2; 9, Mxp; 10, P1; 11, P3; 12, P5; 13, urosome.


Species Haloptilus chierchiae - Plate 2 of morphological figuresissued from : R.B.S. Sewell in The John Murray Expedition, 1933-34, Scientific Reports, VIII (1), 1947. [p.191, Fig.49].
Female (from Arabian Sea): A, Md; C, Mx1; E, Mx2; H, P1.
Nota: The proportional lengths of the cephalothorax and abdomen as 83 to 17. The proportional lengths of the various segments of the body (cephalon to caudal rami) as 471:137:56:56:88:74:23:18::28:49 = 1000. The separation of the head and the 1st pediger segment appears incomplete (a line of demarcation is visible across the dorsal aspect but disappears in the lateral region), 4th and 5 th fused. The forehead is acutely rounded. A1 25-segmented, overreaches the caudal rami by about the last 6 or 7 segments. Genital segment longer than the three following segments together. In P1 the distal outer angle of exopodal segments 1 to 3 at the base of the marginal spines fringed with a comb of minute spinules.

Male: B, Md; D, Mx1; F, Mx2; G, Mxp; I, P5.
Nota: The proportional lengths of the anterior and posterior region as 80 to 20. The proportional lengths of the various segments of the body (cephalon to caudal rami) as 437: 146:74:61:94:45:29:20:16:29:49 = 1000. Right A1 modified to form a grasping organ. A2 resembles that of the female, exopod very short and composed of 8 segments.
