description: <i>Phlogiellus jiaxiangi</i> Lin &amp; Li, sp. nov. (Figs 34A–C, 35A–G, 36A–G, 37A–E) Diagnosis. Male of <i>P. jiaxiangi</i> Lin &amp; Li, <b>sp. nov.</b> is similar to <i>P. xinping</i> (Zhu &amp; Zhang, 2008) by having lyra setae and the same angle of the E relative to the bulb (Figs 37E–F), and females of the new species are similar to <i>P. xinping</i> by having one pair of S. <i>P. jiaxiangi</i> Lin &amp; Li, <b>sp. nov.</b> can be separated from <i>P. xinping</i> by the curved lyra setae on the maxillae. The male of <i>P. jiaxiangi</i> Lin &amp; Li, <b>sp. nov.</b> can be distinguished from <i>P. xinping</i> by the ratio of the width of the longitudinal keel to the embolus base in ventral view is 1:18 (<i>vs.</i> 1: 4 in <i>P. xinping</i>) and dense racket-shaped setae on the cymbium in <i>P. jiaxiangi</i> Lin &amp; Li, <b>sp. nov.</b> (<i>vs.</i> sparse in <i>P. xinping</i>). Females can be differentiated from <i>P. xinping</i> by having the base of the S extended, and the length-width ratio of the S almost 2:1 (<i>vs.</i> 3: 1 in <i>P. xinping</i>). Description. Male (holotype, IZCAS-Ar42446, Figs 34A–C, 35A–G, 36D–E). Total length 10.18, carapace 5.85 long, 5.08 wide, dark brown with long setae. Opisthosoma 6.16 long, 4.24 wide, oval, brown, hirsute. Eye group 1.21 long, 0.62 wide. MOA 0.44 long, anterior width 0.56, posterior width 0.71. Eye sizes and interdistances: ALE 0.32, AME 0.29, PLE 0.26, PME 0.20; ALE–AME 0.02, AME–AME 0.10, PLE–PME 0.02, PME–PME 0.44. Fovea transverse, recurved. Chelicerae dark brown, with row of 11 promarginal teeth, 24 mesoventral denticles. Labium wider than long, with ca. 283 cuspules. Sternum yellow-brown with 3 pairs of sigilla. Legs with long and short setae. Tarsi I–III with 2 claws without denticles, tarsus IV with 3 claws, no denticles on paired claws. Bent tarsi present on legs II–IV.

Leg formula 4123. Palp (Figs 34A–C, 35A–B, G). Maxillae without lyra setae, with ca. 223 cuspules ventrally. Tibia with many setae laterally, swollen at base. Bulb nearly globose, E curved, sickle shaped, with a vertical ridge. Female (paratype, IZCAS-Ar42449, Figs 36A–C, F–G). Total length 15.87, carapace 6.38 long, 5.34 wide, similar to that of male. Opisthosoma 9.21 long, 6.32 wide, oval, gray, hirsute. Eye group 1.21 long, 0.71 wide. MOA 0.62 long, anterior width 0.77, posterior width 0.91. Eye sizes and interdistances: ALE 0.31, AME 0.22, PLE 0.31, PME 0.14; ALE–AME 0.10, AME–AME 0.18, PLE–PME 0.07, PME–PME 0.72. Chelicerae with row of 11 promarginal teeth, 31 mesoventral denticles. Labium with ca 262 cuspules. Palp maxillae without lyra setae. Tarsi I–III with 2 claws without denticles, tarsus IV with 3 claws, no denticles on paired claws. Bent tarsi inconspicuous. Leg measurements: Leg I 14.02 (4.10 + 5.51 + 2.42 + 1.99); leg II 12.62 (2.16 + 2.21 + 4.31 + 3.94); leg III 10.46 (2.24 + 2.21 + 3.23 + 2.78); leg IV 14.19 (2.22 + 3.10 + 5.05 + 3.82). Leg formula 4123. Female genitalia (Figs 36A–C) simple. Two separate S, swollen distally, without wrinkles. Material examined.

The species is named after the collector Mr. Jiaxiang Wu and is a noun (name) in genitive case. Variation. Female (paratypes; <i>n</i> = 4). Total length 8.22–20.18. Carapace 4.00–11.42 length, 3.15–6.52 wide. Chelicerae with row of 8–11 promarginal teeth, 21–31 mesoventral denticles. Labium cuspules 195–283.
