Head round. Eyes occupying most of head surface; grouped in one field on each side of head. Antennae 1 of males with 2-articulate peduncle; flagellum with large, crescent-shaped callynophore, with aesthetascs arranged in two-field brush medially, with three smaller articles inserted on antero-dorsal corner. Antennae 1 of females with 2-articulate peduncle; callynophore as broad as flagellum, with two smaller articles inserted medially on postero-distal corner. Antennae 2 of males 5-articulate; strongly zig-zagged, with most articles folded back on each other, extending anteriorly under head and posteriorly between the gnathopoda and pereopoda to pereonite 4; basal article distinctly inflated, about half or less the length of following article; articles 3–5 progressively slightly shorter than preceding one; terminal article pointing anteriorly. Antennae 2 of females 4- articulate. Mandibular incisor styliform, with reduced number of teeth; in male orientated more or less parallel to palp. Maxillae 1 consisting of elongate, rectangular plates with few robust setae on distal margin. Maxillae 2 absent. Maxilliped with inner lobes completely fused; medial margin of outer lobes with membranous fringe.
