CHINA : Yunnan Province : Holotype : ♂ (MHBU-ARA-00023861), Chuxiong Yi Autonomous Prefecture , Chuxiong City , Zixi Mountain , 25.0063°N , 101.4333°E , 2172 m a.s.l. , 25 June 2022 , L. Zhang , W. Wang , M. Xu , & Z. Liu leg. Etymology. The specific epithet is a noun in apposition, and refers to the Yi ( Ḇ ) people, a main ethnic group living in the type locality. Diagnosis. The new species resembles Phintella cholkei Prajapati, Kumbhar, Caleb, Sanap & Kamboj, 2021 and P. longapophysis Lei & Peng, 2013 in the long RTA and short embolus. It can be distinguished from P. cholkei by RL not elongated ( Figs 118, 120 ; vs. RL elongated in P. cholkei , see Prajapati et al . 2021: 234 , figs 16–17); the distinctly bent tip of RTA ( Figs 118, 120 ; vs. weakly bent in P. cholkei , see Prajapati et al . 2021: 234 , figs 16–17). It differs from P. longapophysis by the embolus (left palp) pointing to 10 o'clock in ventral view ( Figs 118, 120 ; vs. pointing to 1 o'clock in P. longapophysis , see Lei & Peng 2013: 101 , figs 2a–b); the RTA being nearly perpendicular to the cymbium ( Figs 116, 118, 120 ; vs. RTA and cymbium at acute angle in P. longapophysis , see Lei & Peng 2013: 101 , figs 2a–b). Description. Male. Habitus as in Figs 111–112 . Measurements of holotype : carapace 1.55 long, 1.38 wide; opisthosoma 1.75 long, 1.11 wide; eyes: AME 0.37, ALE 0.19, PME 0.09, PLE 0.16; legs: Ⅰ 2.95 (0.89, 0.45, 0.73, 0.46, 0.42), II 2.46 (0.72, 0.37, 0.53, 0.44, 0.40), III 2.94 (0.87, 0.38, 0.59, 0.58, 0.52), IV 3.35 (1.06, 0.38, 0.71, 0.71, 0.49); leg formula 4132. Carapace brown, with white lateral margins ( Fig. 111 ). Chelicerae brown, with two promarginal teeth and one retromarginal tooth, front with white scales and a bump ( Figs 114–115 ). Opisthosoma yellow, covered with white scales except black median band dorsally and a black venter ( Fig. 111 ). Legs yellow, expect black femur Ⅰ and tibia Ⅰ ( Fig. 113 ). Palp (116–120): embolus minute; RTA long, perpendicular to cymbium, and strongly bent at tip; PL short and pointing to prolateral side in ventral view. Natural history. Foliage dwellers. Distribution. China ( Yunnan ) ( Fig. 1 ).
