Description. Maximum size male 3.4 mm, female 3.6 mm. Body unpigmented. Eyes absent. Body ovoid; outline slightly stepped between pereon and pleon (Figs 2A, 6 A–C, 7). Pereon tergites (Fig. 2B) very convex, with fine honeycomb basal structure (Fig. 6D). First pereon epimera directed obliquely forward; 2–4 expanded towards outside, 5–7 directed obliquely backwards. Cephalon (Figs 2C, 6B) with triangular frontal lobe, with rounded tip raised upwards; lateral lobes rounded, directed obliquely forward; central tubercle large, subconical, divided into 2 lobes and with 2 other accessories subapical; central posterior tubercle smaller, bilobate; two less prominent lateral protuberances; two small prominences between front and central lobe. Pereonites 1–6 (Fig. 2B) with four raised tubercles (2+2); central tubercles larger than external ones; two rugosities on each side. Pereonite 7 (Figs 2B, 6C) with 2 large, closely, central tubercles, separated basally, and 2 lateral accessory rugosities. Pleonites 3–5 (Fig. 6C) smooth, with moderately developed epimera distally rounded and directed backwards. Telson trapezoidal, with slightly concave hind margin. First antenna (Fig. 2D) tri-articulated; basal article, largest; articles 2–3, subequal; distal article with 3 aesthetascs. Second antenna (Fig. 2E, F): flagellum indistinctly tri-articulated with groups of 2–3 aesthetascs in articles 2 and 3. Right mandible (Fig. 3D) with 1 free penicil near lacinia mobilis; left mandible (Fig. 3E) with 2 free penicils. Maxillula (Fig. 3A): outer branch with 5+5 teeth and slender seta; internal branch with 3 penicils and hairy distal lobe; smallest penicil inserted laterodistally. Maxilla (Fig. 3C) with bilobed distal part; internal lobe with 14–15 sensillae; external lobe with 3–4 sensillae and fine hairs; internal lobe approximately twice as wide as external one. Maxilliped (Fig. 3B): endite with 1 thick subconical penicil and strong subapical seta; basal article of palp with 2 setae and rounded distal part with numerous sensillae forming 3 groups. Pereopods (Figs 4A, B, 5A, B): see male sexual characteristics. Uropod sympodites dorsoventrally flattened, reaching pleotelson hind margin; endopod shorter than exopod.
Male. Pereopod 1 (Fig. 4A, B) without modifications. Pereopod 7 (Fig. 5A, B) not modified. Pleopod 1 (Fig. 4C): exopodite subtriangular with posterior lobe rounded distally, shorter than basal part; tip reaching half of endopod length; thick endopod, with subconical tip asymmetrically striated. Pleopod 2 (Fig. 4D): exopod with concave outer margin; internal margin convex, with rounded posterior tip reaching one third of endopod length; endopod with thin distal seta. Genital papilla (Fig. 4E) distally setose.
