Notiocoelotes pseudolingulatus Liu & Li, 2010: 40 , figs 10–11.

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.
