Description
Maximum length: ♂, 3.5 mm; ♀, 4.8 mm. Body outline as in Figure 9A View Figure 9 . Colourless body. Back smooth with some scattered pointed scale-setae ( Figure 9B View Figure 9 ); noduli laterales with b/c and d/c co-ordinates as in Figure 9C View Figure 9 . Cephalon ( Figure 9D, 9E View Figure 9 ) with suprantennal line slightly bent downwards in the middle; eyes absent. Pereonites 1–3 with convex distal margins and rounded posterior corners; pereonites 4–7 with progressively more acute corners ( Figure 9F View Figure 9 ). Telson triangular with slightly convex sides ( Figure 9G View Figure 9 ). Antennule ( Figure 9H View Figure 9 ) with third article longer than first and second; third article with two petaliform apical aesthetascs, two petaliform aesthetascs in the middle and one pointed aesthetasc closer to proximal margin. Antenna ( Figures 9I View Figure 9 , 11A View Figure 11 ) with flagellum slightly longer than fifth article of peduncle; flagellar articles subequal in length; a row of three aesthetascs on second and four aesthetascs on third flagellar article. Mandible with molar penicil consisting of three long and two short setae; left mandible ( Figure 10A View Figure 10 ) with 2 + 1 free penicils and two lines of scales between the two groups of free penicils; right mandible ( Figure 10B View Figure 10 ) with 1 + 1 free penicils. Maxillule outer branch with 4 + 6 (4 pectinate) teeth; inner branch with two short stout penicils ( Figure 10C View Figure 10 ). Maxilla ( Figure 10D View Figure 10 ) deeply bilobate with setose apex, inner lobe slightly larger than outer one, bearing verruca-like protuberances at the base and with tuft of short segmented sticks near medial margin. Maxilliped ( Figure 10E View Figure 10 ) endite with a line of setae in the middle and no penicil; first article of palp with two strong setae. Pereopods with a row of scales on distal margins of ischium, merus and carpus.
Male: Antenna with fifth article of the peduncle distinctly enlarged ( Figure 11A View Figure 11 ). Pereopod 1 ( Figure 11B View Figure 11 ) with no distinct sexual modifications. Pereopod 7 ( Figure 11C View Figure 11 ) ischium with straight sternal margin. Pleopod 1 ( Figure 11D View Figure 11 ) exopod subtriangular; endopod with pointed apical part slightly bent outwards. Pleopod 2 ( Figure 11E View Figure 11 ) endopod with apical part flagelliform, distinctly longer than exopod. Pleopod 3–5 exopods as in Figure 11F–H View Figure 11 .
