Species Haloptilus pacificus - Plate 1 of morphological figuresissued from : J.B.L. Matthews in Bull. Br. Mus. (Nat. Hist.) Zool., 1972, 24 (1). [p.53].
Female (from Bikini Reef): Relative lengths of the metasome (= prosome) and urosoe segments.

Original description (translated by Akira Fuji):
Body transparent.
Prosome 5-segmented.
Urosome 4-segmented.
Ratio of length of prosome to urosome 24 : 5.
A1 25-segmented (the last two each bearing 1 plumose seta) reaching past end of the body; a long seta present on the 16th, 18th, 20th, 23rd, and 24th segments.
Endopodite of A2 much longer than the exopodite.
Posterior lateral corners of the last thoracic segment rounded.Genital segment very long and expanded, somewhat longer than the total of the other urosomal segments.
Both rami of P5 3-segmented; the terminal segment of exopodite with 4 plumose setae.
Caudal rami symmetrical, each ramus bearing 5 furcal setae, one of which is very long *.

* After Matthews, in foot-note, it is necessary to read caudal rami and not P5 in the traduction.
