Type material. Holotype. Female, China, Guangxi, Chongzuo City, Fusui County, Duxiufeng Hill, Shuilongyan Cave, 22º37.388'N, 107º54.047'E, elev. 86 m, 11 July 2011, X. Wang leg., deposited in IZCAS. Paratypes. 1 male, 17 females, same data as holotype, deposited in IZCAS.

Etymology. The specific name is a patronym in honor of Prof. Guodong Ren from Hebei University in Baoding; noun in apposition. A leading taxonomist in Tenebrionidae beetles, Prof. Ren has helped us in field work.

Diagnosis. Females may be distinguished from other Asian Brommella species, except B. tongyanfengi Li, sp. nov. (Figs 45–49), by the copulatory ducts with more rounded coils in ventral view (twisted not irregular in B. tongyanfengi Li, sp. nov.). Spermathecae slightly swollen, straight (swollen as tadpole shape in B. tongyanfengi Li, sp. nov.).

Cervical groove indistinct. Six eyes, AME absent, all eyes white, encircled with black. Eye size and interdistances: ALE 0.06, PLE 0.08, PME 0.05; ALE-PLE 0.00, PLE-PME 0.02, PME-PME 0.07, ALE-ALE 0.10. Eye region length 0.28, width 0.13. Clypeus height 0.08. Chelicerae yellow-brown, chelicerae length 0.40, width 0.20, with distinct lateral condyles and 3 promarginal and 5 retromarginal teeth. Labium and gnathocoxe yellow-brown, sternum yellow. Labium length 0.11, width 0.19. Gnathocoxae length 0.30, width 0.14. Sternum length 0.60, width 0.53. Legs yellow. Leg formula I-IV-II-III. Leg measurements: I 3.71 (1.08, 0.38, 0.95, 0.80, 0.50); II 3.09 (0.90, 0.33, 0.73, 0.68, 0.45); III 2.73 (0.81, 0.31, 0.60, 0.58, 0.43); IV 3.56 (1.05, 0.31, 0.81, 0.89, 0.50). Ratio Cl/Met IV = 0.25, with 9 setae. Opisthosoma 1.08 long, 0.84 wide. Opisthosoma oval, pale, without distinct pattern. Cribellum narrow, undivided.

Epigynum (Figs 31, 35A–B). Width 0.23. Bursae reduced. Copulatory ducts slender, twisted tightly (Figs 31A, 35B). Spermathecae slightly swollen, straight.

Male (paratype). Damaged.

Pedipalpus (Figs 32–34). Cymbium 0.38 long. Embolus long, filiform, originating at approximately 7-o’clock position. TA prolaterally short and simple. RTA large, simple, with a single fold. Base of tibia with a big bifurcated spur.
