Etymology

. The species is named after Mr. Zilong Bai, one of the collectors of the type specimens; noun (name) in genitive case.

Diagnosis

. The new species differs from congeners by the following combination of characters: 1) the abdomen has two transverse patches and one longitudinal patch; 2) the scape is distally widened; 3) the conductor is long, membranous, and basally trifurcated.

Eye sizes and interdistances: AME 0.10, ALE 0.05, PME 0.08, PLE 0.05, AME-AME 0.08, AME-ALE 0.03, PME-PME 0.03, PME-PLE 0.10, MOA length 0.30, anterior width 0.30, posterior width 0.20. Leg measurements: I 5.00 (1.35, 1.75, 1.30, 0.60), II 4.40 (1.30, 1.40, 1.15, 0.55), III 2.95 (0.90, 0.95, 0.70, 0.40), IV 4.20 (1.30, 1.35, 1.05, 0.50). Carapace pear shaped, grayish yellow with black eye region, cervical groove slightly obvious, fovea longitudinal. Chelicerae yellow, four promarginal and three retromarginal teeth. Endites grayish yellow, with a protuberance on anterior lateral margin, labium grayish brown, paler distally. Sternum heart-shaped, grayish yellow. Legs yellow without annulations, femur II with furrow basally, tibia II with 13 macrosetae. Abdomen oval, about 1.55 times longer than wide, with long, grayish brown setae, dorsum grayish yellow with two transverse and one longitudinal grayish brown patch; venter grayish yellow, big grayish brown patch medially. Spinnerets grayish yellow.

Palp (Figs 14 , 21B ): with one patellar bristle; cymbium tip with cluster of long macrosetae, median apophysis about a bulb diameter width, lamellar; embolus tapered and slightly curved; conductor length about equal to bulb diameter, membranous, basally trifurcated; terminal apophysis extremely large, almost triangular in apical view; subterminal apophysis with 3 protuberances.

Female (paratype IZCAS-Ar42551, Fig. 15A, B, E, F ). Total length 3.85. Carapace 1.75 long, 1.20 wide. Abdomen 2.65 long, 2.30 wide. Clypeus 0.05 high. Eye sizes and interdistances: AME 0.13, ALE 0.10, PME 0.13, PLE 0.10, AME-AME 0.08, AME-ALE 0.05, PME-PME 0.03, PME-PLE 0.10, MOA length 0.35, anterior width 0.30, posterior width 0.25.

Habitus similar to that of male but endites without protuberances.

Epigyne (Fig. 15A, B ): wider than long, with distally widened scape; copulatory openings narrow, situated at anterior base of lateral lobes; copulatory ducts slightly curved; spermathecae globular, touching each other.

Variation

. Total length: ♂♂ 2.45-2.60; ♀♀ 3.10-3.85.
