Telson with double-rounded tips. Antennula with eight petaliform aesthetascs. Antennal flagellum with six articles. Molar penicil of mandible with two plumose setae. Male pleopod 1 endopod with four wide scales at apex inner margin. Male pleopod 2 endopod thick and about 1.5 × as long as exopod.
Description.
Maximum body length: ♂ 5 mm, ♀ 6 mm. Body outline as in Fig. 2A View Figure 2 . Colourless, dorsal surface tuberculate with tubercles arranged as follows: cephalon with four rows of tubercles; pereonite 1 with three rows of tubercles; pereonites 2-7 with two rows; pleonites 1 and 2 with one row of tubercles each, pleonites 3-5 and telson smooth, the latter about four times wider than long (Fig. 10B View Figure 10 ). Pleon narrower than pereon. Antennula with three articles (Fig. 8E View Figure 8 ), second article with one row of short setae on outer margin, third article with one row of eight petaliform aesthetascs along outer margin. Antenna long and slender (Fig. 8B View Figure 8 ), flagellum of six articles. Mandible with molar penicil consisting of two branches (Fig. 9C, D View Figure 9 ), basal one more than twice as long as the other; left mandible with 2+1 penicils, right with 1+1 penicils. Maxillula (Fig. 2B, C View Figure 2 ) outer endite with 12 simple teeth and one long seta, inner branch without setae, penicils or spines. Maxilla (Fig. 2D View Figure 2 ) rounded and covered with thin setae and one row of thick setae. Maxilliped (Fig. 2E View Figure 2 ) endite with long apical penicil; epipodite bearing fringe of thin setae on outer margin. Pereopods with long plumose dactylar seta (Fig. 3A-G View Figure 3 ). Uropods (Fig. 10B View Figure 10 ) with protopod slightly longer than wide; exopod bearing one row of scales on inner margin; endopod wider and longer than exopod.
Male. Pleopod 1 (Figs 4A View Figure 4 , 10E View Figure 10 ) endopod with distal part pointed bent inwards, bearing four large transversal scales on the inner side; exopod triangular with no scale-setae (Fig. 4B View Figure 4 ). Pleopod 2 (Figs 4C View Figure 4 , 10H View Figure 10 ) endopod thick and about 1/5 as long as exopod; exopod with one to two setae on apex (Fig. 4D View Figure 4 ).
