Type material.

Holotype ♂ (IZCAS-Ar40608), China: Yunnan: Xishuangbanna, Mengla County, Menglun Town, Menglun Nature Reserve, Leprosy Village (21°53.59'N, 101°17.30'E, ca 550 m), 4.05.2019, Y. Tong et al. leg. Paratypes 5♀3♂ (IZCAS-Ar40609-40616), same data as holotype; 1♀3♂ (IZCAS-Ar40617-40620), Xishuangbanna Tropical Botanical Garden, tropical rainforest (21°55.35'N, 101°16.36'E, ca 610 m), 7.08.2018, C. Wang et al. leg.

Etymology.

The species name is derived from the name of the type locality; noun in apposition.

Diagnosis.

Phintella banna sp. nov. resembles P. bifurcilinea ( Bösenberg & Strand, 1906) by the small size and the shape of the copulatory organs but can be distinguished by the following: 1) the lamellar process is visible in ventral view vs obscured in P. bifurcilinea ( Żabka 1985: fig. 403); 2) the embolus is apically directed anteriorly in ventral view vs directed retrolaterally in P. bifurcilinea ( Żabka 1985: fig. 403); 3) the chelicerae of the male are underdeveloped, the ratio of the length of the fang to the width of the paturon is about 1:1 vs well-developed chelicerae, with a ratio of almost 2.5:1 in P. bifurcilinea ( Żabka 1985: fig. 406); 4) the copulatory openings are anterior to the spermathecae vs lateral to the spermathecae in P. bifurcilinea ( Peng et al. 1993: fig. 527); 5) the copulatory ducts are approximately one-third of the spermathecal diameter vs less than one-fifth of the spermathecal diameter in P. bifurcilinea ( Peng et al. 1993: fig. 527).

Description.

Male (Figs 7 , 8C, D, F, G ). Total length 2.41. Carapace 1.34 long, 1.02 wide. Abdomen 1.12 long, 0.88 wide. Clypeus 0.10 high. Eye sizes and inter-distances: AME 0.33, ALE 0.17, PLE 0.15, AERW 1.01, PERW 0.98, EFL 0.64. Legs: I 2.73 (0.82, 0.98, 0.59, 0.34), II 2.66 (0.80, 0.93, 0.59, 0.34), III 3.25 (1.01, 1.07, 0.83, 0.34), IV 3.46 (1.10, 1.12, 0.90, 0.34). Carapace dark brown, slightly paler medially in the thoracic area, with yellow and pale scales on the cheeks. Clypeus dark brown. Fovea indistinct. Chelicerae yellow-brown to brown, with one retromarginal tooth and two promarginal teeth. Endites green-brown, pale yellow along the inner edge. Labium wider than long, paler terminally. Sternum green-brown, covered with thin setae. Legs pale to green-brown. Abdomen oval, dorsum hairy, with two pairs of muscle depressions and a transverse white band of scales in the center, followed by recurved dotted lines; venter colored as dorsum, darker medially.

Palp (Fig. 7A-D ): tibia wider than long, with a tapered RTA terminally curved towards the bulb and pointed apically in retrolateral view; bulb flat, with a lamellar process near the base of the embolus, approximately three times longer than wide, with a small subtriangular bump and a gently curved posterior lobe reaching the middle of the tibia in ventral view; sperm duct long, strongly curved anteriorly; embolus bar-shaped, almost equal to the length of the lamellar process.

Female (Fig. 8A, B, E ). Total length 3.07. Carapace 1.29 long, 1.04 wide. Abdomen 1.76 long, 1.33 wide. Clypeus 0.10 high. Eye sizes and inter-distances: AME 0.32, ALE 0.18, PLE 0.16, AERW 1.04, PERW 1.01, EFL 0.67. Legs: I 2.31 (0.73, 0.80, 0.49, 0.29), II 2.25 (0.71, 0.76, 0.44, 0.34), III 2.88 (0.88, 0.93, 0.73, 0.34), IV 3.31 (1.02, 1.07, 0.88, 0.34). Habitus similar to that of the male except the transverse abdominal white band is indistinct laterally, and the dorsum of the abdomen with a brown, thin, longitudinal band in the middle.

Epigyne (Fig. 8A, B ): wider than long, with an arc-shaped basal plate; copulatory openings anteriorly located, slit-shaped, the distance between them almost equal to the spermathecal diameter; copulatory ducts curved anteriorly, and then descend along the longitudinal axis to connect to the postero-ento-lateral part of the spermathecae; spermathecae spherical, separated from each other by less than one-third their diameter; fertilization ducts well-developed, lamellar, anterior to spermathecae.

Distribution.

Known only from the type locality in Yunnan, China.
