Diagnosis

Carapace trapezoidal, triangular or reniform, surface ornamented. Marginal zone wide (anteriorly more than 20% of total length). Antennula 5-segmented. Third and fourth segments as well as fifth and sixth fused. Posteriorly, chitinous margin between fused segments uninterrupted, anteriorly with one seta at the points of fusion. Exopodite of antenna plate with one seta which can be less than twice or more than five times as long as other two short setae. Mandibular palp with two setae on the outer side of second segment, penultimate segment with five setae intero-medially; terminal segment less than twice as long as wide, terminal claw strongly sclerotised and fused with terminal segment. Third endite on maxillula with two plumose claws. First thoracopod with two "Ta" setae, and three setae in exopodite; "Tb" and "Td" setae also present. Second thoracopod 4- or 5-segmented, basal segment without seta, penultimate segment with short setae. T3 4- or 5-segmented. Basal segment with three setae (d1, d2, dp); terminal segment with two short (Th1 & Th2) and one long (Th3) seta, the latter with two spines at the beginning of its last third. Caudal ramus with posterior claw reduced to a seta; posterior as well as anterior seta not always present. Hemipenis with lobe "a" which is square-shaped and extended compared with other parts. Lobe "b" with one well chitinised acutiform part which positioned latero-distally. Lobe "h" not well chitinised and double folded. Medial chitinous part ("g" lobe) protruded between lobes, well chitinised on distal margin, as well as medio-ventrally and on its basal part, while medio-dorsally very poorly sclerified. Zenker's organ with 5+2 rows of spines. Female genital lobe rounded, and without extensions.
