Body shape robust or globular. Head rounded. Eyes occupying most of head surface, grouped in one field on each side of head. Antennae 1 of males with 1-articulate peduncle; flagellum with large, crescentshaped callynophore, with aesthetascs arranged in one-field brush medially; with two smaller articles inserted on antero-dorsal corner. Antennae 1 of females without peduncle; callynophore narrowly rectangular; with one smaller article inserted terminally. Antennae 2 absent in females. Antennae 2 of males 5-articulate; strongly zigzagged, with most articles folded back on each other; extending anteriorly under head and posteriorly between the gnathopoda and pereopoda to pereonite 2; basal article distinctly inflated, about half or less the length of following article; last two articles sub-equal in length to preceding one; terminal article pointing anteriorly. Mandibular incisor relatively broad, with several teeth; in male orientated more or less parallel to palp. Maxillae 1 very reduced in size, consisting of plate-like lobes, with four rounded teeth distally on medial margin. Maxillae 2 very reduced in size; bi-lobed, with two terminal teeth or robust setae on each lobe. Maxilliped with inner lobes completely fused; medial margin of outer lobes with membranous fringe. Gnathopods 1 &amp; 2 simple. Pereopods 3 &amp; 4 distinctly shorter than pereopods 5 &amp; 6. Pereopod 5; basis about

Pereopod 7 reduced in size with basis not particularly enlarged, usually with only 13 terminal articles, but sometimes all articles are present. Uropod 1 with articulated exopoda and endopoda. Uropod 2; endopod sometimes fused with peduncle. Uropod 3; endopod fused with peduncle. Rami of all uropoda more-or-less lanceolate, usually with serrated margins.
