Description. Body with 31 segments (including telson) in adults.

MEASUREMENTS. Males 10–12 mm long, vertical diameter of the largest pleurotergite 0.85–1 mm. Females 9– 11.5 mm long, vertical diameter of the largest pleurotergite 0.85–1 mm.

COLORATION ( Fig. 129 View FIGURE 129 ). Yellowish, with traces of greyish and brownish pigmentation.

HEAD. Without frontal depression in males. Labrum with three medial teeth and 5+4 labral and 2+2 supralabral setae. Promentum triangular, without setae. Lingual plates with 6+5 setae, on each plate arranged in 1–2 irregular rows. Stipites with ca 20+20 setae. Antennae 1.6 mm long in holotype. Length of antennomeres (in mm): I (0.08), II (0.18), III (0.42), IV (0.23), V (0.38), VI (0.15), VII (0.12) and VIII (0.04). Length/breadth ratios of antennomeres I–VII: I (1), II (2), III (5), IV (2.5), V (3.5), VI (1.3) and VII (1.2). Antennomeres II, IV, V, VI and VII with one, three, one, four and one sensillum, respectively. Number of ocelli 15–18, arranged in 4–6 rows in both sexes.

COLLUM. Narrower than head, with six macrochaetae. Anterior edge semi-circular, posterior margin gently concave.

BODY SEGMENTS ( Figs 129 View FIGURE 129 , 130 View FIGURE 130 ). Lateral keels like lateral swellings. Macrochaetae medium-sized and trichoid. CIX (pleurotergite 15) ~ 1.4; MIX (pleurotergite 15) ~ 0.5; PIX (pleurotergite 15) ~ 0.7; MA (pleurotergite 15) ~ 110˚.

TELSON. Epiproct with a pair of spinnerets and 3+3 setae (1+1 paramedian, 2+2 marginal). Hypoproct with 1+1 apical setae. Paraprocts with 3+3 marginal setae.

WALKING LEGS. In both sexes, leg-pairs 1 and 2 with tarsal combs; prefemora with several long and robust setae; femora and postfemora with a group of several long and robust setae.

MALE SEXUAL CHARACTERS ( Fig. 131 View FIGURE 131 ). Leg-pairs 3–7 enlarged, especially so leg-pairs 3, 4 and 7. Leg-pairs 3 and 4 each with a basal external protrusion on prefemur; prefemur and femur thickened. Leg-pair 5 with a basal, subtriangular, oral protrusion on femur. Leg-pair 6 without peculiarities. Leg-pair 7 with a well-developed, spatulated, lamellar, posterior, coxal process; prefemora with a bump. Leg-pair 10 with coxal glands and a posterior coxal horn. Leg-pair 11 with coxal glands, without other peculiarities.

ANTERIOR GONOPODS ( Figs 132 View FIGURE 132 , 133 View FIGURE 133 A–F). Sternal plate (sp) with an anterior, medial, hairy, sternal sac (ss). Coxal processes completely fused basally; consisting of a medial part (mp) and two lateral parts (lp). Medial part with a longitudinal medial groove (lg); apically, with a pair of posteriorly curved horns (h); subapically, on lateral side with a U-shaped rift; posteriorly, with a nippled part (wp). Lateral parts with an anterior lamellar structure (al); posteriorly with a C-shaped lever (lv), this latter being orientated anteriorly; levers with an additional subapical process (apr). Gonopods are characterized by the presence of a pair of hidden anterior processes (hap) situated on both sides of the medial part, only their upper third visible, passing through the U-shaped rift of medial part. Posteriorly, with a medial syncoxal vesicle (scv), as well as with a pair of hairy levers (hl) and an additional process with minute setae (aps).

POSTERIOR GONOPODS ( Fig. 133 View FIGURE 133 G, H). Coxited (c) divided. Telpodites (t) present on posterolateral side. Coxal processes (cp) simple, curved posteriorly. Anterior side carrying a membranous crest (mc). Coxal vesicles (cv) placed basally on anterior side.
