description: <i>Brommella tongyanfengi</i> Li, sp. nov. (Figs 45–49, 97) Type material. Holotype. Male, China, Guangxi, Laibin City, Xiangzhou County, Xiangzhou Town, cave without name, 23°57.278´N, 109°39.696´E, elev. 114 m, 10 October 2010, X. Wang &amp; L. Lin leg., deposited in IZCAS. Paratypes. 24 females, same data as holotype, deposited in IZCAS. Etymology. The specific name is a patronym in honor of Prof. Yanfeng Tong from Shenyang Normal University in Shenyang; noun in apposition. Prof. Tong is a leading taxonomist in Oonopidae in China. Diagnosis. This new species is similar to <i>B. punctosparsa</i> (Song, Zhu &amp; Chen, 1999: 363, figs 213K–N), but can be distinguished by the oar-shaped dictynid TA dorsal apophysis, ending with row of denticles (acuminate and hooked in <i>B. punctosparsa</i>), medial apophysis short finger-shaped (obtuse triangle-shaped in <i>B. punctosparsa</i>). Description. Male (holotype). Total body length 2.25 (Fig. 49E). Prosoma length 1.00, width 0.75. Cephalic region width 0.45. Cephalic part relatively flat, off-white, covered with several setae, fovea reduced, Prosoma margin dark. Six eyes, AME absent, all eyes white, encircled with black. Eye diameters: ALE 0.08, PLE 0.09, PME 0.05. Eye interdistances: ALE-PLE 0.01, PLE-PME 0.03, PME-PME 0.08, ALE-ALE 0.08. Eye region length 0.17, width 0.30. Clypeus height 0.11. Chelicerae length 0.50, width 0.20. Chelicerae with distinct lateral condyles, 3 promarginal and 5 retromarginal teeth. Labium and gnathocoxae brown, sternum light brown. Labium length 0.08, width 0.18. Gnathocoxae length 0.28, width 0.20. Sternum length 0.60, width 0.58. Leg formula I-IV-II-III. Leg measurements: I 3.95 (1.10, 0.35, 1.05, 0.85, 0.60); II 3.35 (0.95, 0.35, 0.80, 0.75, 0.50); III 2.85 (0.85, 0.30, 0.60, 0.65, 0.45); IV 3.70 (1.05, 0.35, 0.90, 0.90, 0.50). Ratio Cl/Met IV = 0.43, with 7 setae. Opisthosoma length 1.25, width 1.10. Opisthosoma beige, without distinct pattern. Cribellum narrow, undivided. Pedipalpus (Figs 45–46, 48). Cymbium 0.46 long. Embolus long, filiform, originating from approximately 6-o’clock position. TA prolaterally short and simple. Prolateral part of TA with a short finger-shaped apophysis, constricted medially. RTA very large, curved, with a single fold. Base of tibia with a big bifurcated spur. Female (one of the paratypes). Total body length 2.50 (Figs 49C–D). Prosoma length 0.93, width 0.70. Cephalic region width 0.43. Eye diameters: ALE 0.07, PLE 0.08, PME 0.06. Eye interdistances: ALE-PLE 0.02, PLE-PME 0.04, PME-PME 0.05, ALE-ALE 0.06. Eye region length 0.15, width 0.30. Clypeus height 0.08. Chelicerae length 0.38, width 0.20. Chelicerae with distinct lateral condyles, 3 promarginal and 6 retromarginal teeth. Labium length 0.11, width 0.19.
