Material examined. Holotype male ( SCAU n6), China, Sichuan, Mianyang City , Beichuan County, Cave Liangshui Dong , 31°55’30’’N, 104°40’56’’E, 1000 m a.s.l., 2014-VII-16, leg. Weixin Liu, Haomin Yin, Sunbin Huang & Xinhui Wang. GoogleMaps
Paratypes: 2 males, 3 females, 5 juv. ( SCAU n7), same locality and collecting data as in the holotype .
Etymology. To emphasize the anterior gonopod sternum bearing not only a large median lobe, but also two small lateral lobules; feminine adjective.
Diagnosis. Differs from congeners by the anterior gonopod sternum carrying a large median and two small lateral lobes, as well as the posterior gonopod bearing a foot-shaped colpocoxite.
Description. Length of both sexes ca 27–29 mm, midbody width 3.2–3.5 mm. Color in life ( Figs 2 View FIGURE 2 B, 10) light brown, marbled; head, antennae and eye patches dark brown.
Body with 30 segments. In width, collum <segment 2 <3 <head <4–5 <6–17; posterior to segment 18, body gradually tapering towards telson ( Fig. 10 View FIGURE 10 A). Clypeolabral region densely setose, slightly convex.
Eye patches triangular, each composed of 26 convex ocelli.
Antennae ( Fig. 12 View FIGURE 12 ) long and slender, reaching posterior to body segment 5 when stretched posteriorly; antennomere 7 with very small four apical cones.
Mandible with a movable external tooth with two cusps, and an internal tooth with six cusps.
Collum with rudimentary paraterga ( Fig. 10 View FIGURE 10 A). Integument smooth and shining, only prozonites distinctly and densely striolate transversely. Metatergal setation 3 + 3, typical, macrochaetae long, rather thick, but pointed, placed on clear knobs ( Fig. 10 View FIGURE 10 A); stricture between pro- and metazona shallow, inconspicuous ( Fig. 10 View FIGURE 10 A). Paraterga well-developed, high dorsolateral shoulders ( Fig. 10 View FIGURE 10 A).
CIX (15) = 0.37; MIX (15) = 1.49; MA (15) = 120°; PIX (15) = 0.62 ( Fig. 13 View FIGURE 13 A). Axial suture distinct, pallid, usual ( Fig. 10 View FIGURE 10 A).
Legs long and slender ( Fig. 10 View FIGURE 10 ), about 2.0 (♂) or 1.3 (♀) times as long as midbody height. Legs 1 and 2 slightly reduced, tarsi with usual ventral brushes, but without papillae. Other tarsi with conspicuous papillae (p) ventrally ( Fig. 11 View FIGURE 11 ). Male legs 3–7 distinctly incrassate, pairs 3 and 4 particularly so. Male femora 3 and 4 each with a small, but evident, mushroom-like protuberance (m) at midway ventrally ( Fig. 11 View FIGURE 11 A–B). Male legs 10 with coxal glands (cg) ( Fig. 11 View FIGURE 11 C); coxa 11 with highly vestigial glands, pilose apically; prefemur 11 with a strong basal process (d) ventrally ( Fig. 11 View FIGURE 11 D). Claws simple, long.
Male segment 7 slightly broader than adjacent ones, with ridge-like pleural arches.
Anterior gonopods ( Figs 12 View FIGURE 12 A–B, 13B) reduced, sternum with a large median lobe (ml) distally in caudal view and with two small lateral lobules (ll); coxites (cxi) slender and long. Posterior gonopods ( Figs 12 View FIGURE 12 C–D, 13C–D) hypertophied, with a foot-shaped colpocoxite (c) and a large bush-like structure (b) on caudal face; telopoditomere 1 (t1) particularly strongly setose, telopoditomere 2 (t2) very well-developed.
Female: Segment 3 conspicuously broadened. Vulva ( Fig. 13 View FIGURE 13 E) with a very long basal process (p) and a small process on operculum (op), tip of the latter bifid.
Remarks. According to the light brownish body and ocelli, the relatively short legs, as well as the number of ocelli, N. lobata sp. nov. is likely to be a troglophile.
