Description
Maximum length: ♂ and ♀, 2.5 mm. Body outline as in Figure 14A View Figure 14 . Body colourless. Dorsum covered with semicircular scales and numerous fan-shaped scale setae ( Fig. 14G View Figure 14 ); noduli laterales with b/c and d/c coordinates as in Figure 14B View Figure 14 ; gland pores not visible. Cephalon ( Fig. 14C–E View Figure 14 ) with suprantennal line bent down in the middle; eyes reduced, consisting of four ommatidia. Telson with distal part triangular, with straight sides and obtuse apex ( Fig. 14F View Figure 14 ). Antennule ( Fig. 14H View Figure 14 ) with first and third articles subequal in length, second article shorter; third article with two long apical aesthetascs and a tuft of six aesthetascs on medial margin. Antenna ( Fig. 14I View Figure 14 ) reaching back middle pereonite 2; fifth article of peduncle swollen; flagellum as long as fifth article of peduncle, distal flagellar article longer than first and second, and bearing two aesthetascs, apical organ as long as distal article of flagellum, showing sensory hairs enclosed by a common tube-like sheath, free sensilla short and inserted at one-quarter of the length of the apical organ. Mandibles ( Fig. 15A,B View Figure 15 ) with molar penicil consisting of five branches, 2 + 1 free penicils on the left and 1 + 1 on the right mandible. Maxillule ( Fig. 15C View Figure 15 ) outer branch with 4 + 5 teeth (four cleft); inner branch with two long narrow penicils at apex. Maxilla ( Fig. 15D View Figure 15 ) with setose and bilobate apex; outer lobe about twice as wide as inner lobe, and with distal margin rounded. Maxilliped ( Fig. 15E View Figure 15 ) basis rectangular, with sparse triangular scale setae; endite with short setae and two triangular teeth at apex. Pereopods dactylus with long inner claw, ungual and dactylar setae flagelliform, with simple apex. Pereopod 1 ( Fig. 15G View Figure 15 ) with transverse antennal grooming brush and one seta with handlike apex. Uropod (15F) with exopod distinctly longer than endopod.
Male: Pereopod 7 ( Fig. 16A View Figure 16 ) ischium with sternal margin slightly convex and bearing two long setae. Genital papilla ( Fig. 16B View Figure 16 ) with a triangular ventral shield and two apical orifices. Pleopod 1 ( Fig. 16C View Figure 16 ) exopod triangular, about as wide as long, with medial and outer margins rounded; endopod with distal portion bearing a subapical triangular lobe on medial margin, acute apex. Pleopod 2 ( Fig. 16D View Figure 16 ) exopod triangular, outer margin slightly concave and bearing one seta; endopod with short basal article, narrow distal article about twice as long as exopod, with distal portion equipped with some triangular teeth and an arrow-like apex. Pleopods 3 and 4 exopods ( Fig. 16E,F View Figure 16 ) subquadrangular, bearing three and four setae, respectively. Pleopod 5 exopod ( Fig. 16G View Figure 16 ) triangular, outer margin convex, bearing three long setae, acute apex.
