Diagnosis. Female of the species closely resembles N. lingulatus Wang, Xu & Li, 2008, both having small atrium, round and separated spermathecal bases, but can be easily distinguished by the arc-shaped anterior atrial edge, the triangular atrial scape, the thin copulatory ducts and the anteriorly originated spermathecal heads (Fig. 2–3); whereas N. lingulatus has a nearly square-shaped atrium with straight anterior atrial edge, a tongue-shaped atrial scape, broad and semi-circular copulatory ducts (cf. Wang, Xu & Li, 2008: Figs 9–11). Male is similar to N. sparus (Dankittipakul, Chami-Kranon & Wang, 2005) having long embolus, posteriorly extended conductor and cymbial furrow almost half of cymbial length, but distinguished by the broad, blunt conductor apex (acute apex of N. sparus) and the wide distance between RTA and LTA (Figs 4–6, cf. Wang, Xu & Li, 2008: Figs 32–34).
Description. Male. Small sized coelotine. Total body length 4.31; prosoma 2.26 long, 1.50 wide; opisthosoma 1.87 long, 1.10 wide. Prosoma yellow, longer than wide, cephalic region narrow (Fig. 1). Median furrow distinct, longitudinal. Radial groove obvious, gray. Anterior eye row recurved, posterior eye row almost straight from above. Eye sizes and interdistances: AME 0.03, ALE 0.08, PME 0.09, PLE 0.08; AME–AME 0.03, AME–ALE 0.04, PME–PME 0.04, PME–PLE 0.03. MOA 0.20 long, anterior width 0.12, posterior width 0.25. Chelicerae yellow brown, with 3 promarginal and 2 retromarginal teeth. Endites, labium and sternum yellow. Legs yellow, with gray bands. Leg measurements: I 7.02 (1.82, 0.57, 1.70, 1.73, 1.20); II 5.56 (1.55, 0.55, 1.25, 1.33, 0.88); III 5.49 (1.52, 0.60, 1.17, 1.50, 0.70); IV 7.60 (2.05, 0.72, 1.73, 2.20, 0.90). Leg formula: 4123. Opisthosoma dorsally light gray (Fig. 1), longer than wide, anteriorly with a large gray spot; venter yellow. Spinnerets yellow.
Palpus (Figs 4–6) without patellar apophysis; RTA small, and LTA strongly bifurcated; cymbial furrow about half length of cymbium or slightly longer; conductor long, but slightly coiled comparing to other congeners; conductor dorsal apophysis absent; conductor lamella moderately large; median apophysis reduced; embolus filiform, arising at approximately 9:00–o’clock-position.
Female. Total length 4.41–4.47; one female was measured, body length 4.47: prosoma 2.07 long, 1.42 wide; opisthosoma 2.25 long, 1.57 wide. Eye sizes and interdistances: AME 0.04, ALE 0.08, PME 0.08, PLE 0.05; AME– AME 0.04, AME–ALE 0.02, PME–PME 0.07, PME–PLE 0.06; MOA 0.19 long, anterior width 0.12, posterior width 0.25. Chelicerae brown, with 3 promarginal and 2 retromarginal teeth. Leg measurements: I 5.60 (1.50, 0.55, 1.30, 1.27, 0.98); II 4.67 (1.37, 0.53, 0.97, 1.05, 0.75); III 4.62 (1.40, 0.40, 1.10, 1.20, 0.52); IV 6.23 (1.70, 0.62, 1.45, 1.69, 0.77). Leg formula: 4123. Opisthosoma dorsally gray; venter light gray. Other characters as in male.
Epigynum (Figs 2–3) without teeth; atrium small, length and width subequal; atrial scape distinct, situated on posterior atrial edge; copulatory ducts large, anteriorly originating; spermathecae small, rounded, widely separated; spermathecal heads concealed by copulatory ducts from dorsal view.
