Type material
. Holotype ♂ (IZCAS-Ar42544), China: Yunnan, Xishuangbanna, Mengla County, Menglun Town, Menglun Nature Reserve, G213 roadside, Mannanxing (21°53.49'N, 101°17.11'E, ca 560 m), 9.VIII.2018, C. Wang leg. Paratypes: 1♀ (IZCAS-Ar42545), same data as holotype; 2♂ (IZCAS-Ar42546-42547), along G213 roadside (21°53.55'N, 101°16.39'E, ca 540 m), 3.VIII.2018, C. Wang leg.
Etymology
. The specific name comes from the Latin word “pulla”, meaning "dark, blackish", referring to the dark markings at the eye region; adjective.
Diagnosis
. The new species resembles H. pygmaea (Sundevall, 1831) in habitus but can be distinguished by the: 1) enlarged copulatory ducts vs. not enlarged ( Yin et al. 1997: fig. 215d); 2) spermathecae touching vs. separated from each other ( Yin et al. 1997: fig. 215d); 3) embolus length less than half a bulb diameter vs. longer than a bulb diameter ( Yin et al. 1997: fig. 215e).
Description
. Male (holotype, Figs 12 View Figure 12 , 13C, D View Figure 13 , 21A View Figure 21 ). Total length 2.40. Carapace 1.10 long, 0.95 wide. Abdomen 1.45 long, 0.90 wide. Clypeus 0.18 high. Eye sizes and interdistances: AME 0.06, ALE 0.04, PME 0.05, PLE 0.04, AME-AME 0.05, AME-ALE 0.03, PME-PME 0.05, PME-PLE 0.05, MOA length 0.15, anterior width 0.15, posterior width 0.15. Leg measurements: I 4.00 (1.30, 1.35, 0.90, 0.45), II 3.60 (1.15, 1.20, 0.85, 0.40), III 2.45 (0.80, 0.75, 0.55, 0.35), IV 3.75 (1.25, 1.20, 0.90, 0.40). Carapace pear shaped, yellow with black patch in eye region, cervical groove inconspicuous, fovea transverse. Chelicerae yellow, three promarginal teeth, two retromarginal teeth. Endites yellow, labium triangular, yellow. Sternum yellow, with sparse, dark setae. Legs grayish brown, without annulations. Abdomen elliptical, about 1.6 times longer than wide, covered with pale setae, dorsum black-brown; venter grayish brown with big black patch medially. Spinnerets brownish black.
Palp (Figs 12 View Figure 12 , 21A View Figure 21 ): with two patellar bristles; median apophysis hooked; embolus shorter than half bulb diameter, covered by terminal and subterminal apophyses in prolateral view; conductor thick; terminal apophysis membranous, bifurcated distally; subterminal apophysis membranous, width almost same as width of terminal apophysis; tegulum extended near conductor.
Female (paratype IZCAS-Ar42545, Fig. 13A, B, E, F View Figure 13 ). Total length 2.75. Carapace 1.00 long, 0.90 wide. Abdomen 2.00 long, 1.45 wide. Clypeus 0.13 high. Eye sizes and interdistances: AME 0.06, ALE 0.04, PME 0.05, PLE 0.04, AME-AME 0.05, AME-ALE 0.05, PME-PME 0.05, PME-PLE 0.05, MOA length 0.15, anterior width 0.15, posterior width 0.18. Leg measurements: I 3.10 (0.95, 1.05, 0.70, 0.40), II 2.85 (0.90, 0.95, 0.65, 0.35), III 2.00 (0.65, 0.60, 0.45, 0.30), IV 3.00 (1.00, 0.95, 0.70, 0.35). Habitus similar to that of male; carapace a little darker.
Epigyne (Fig. 13A, B View Figure 13 ): pentagonal in anterior view, about 1.4 times wider than long; copulatory openings laterally situated; copulatory ducts large, wider than spermatheca diameter at its widest part; spermathecae globular, touching each other.
