Treatment

Brommella renguodongi Li View in CoL , sp. nov. ( Figs 31–35 View Figure 31 View Figure 32 View Figure 33 View Figure 34 View Figure 35 , 97 View Figure 97 )

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 GoogleMaps . Paratypes. 1 male, 17 females, same data as holotype, deposited in IZCAS GoogleMaps .

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 View Figure 45 View Figure 46 View Figure 47 View Figure 48 View Figure 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.).

Description. Female (holotype). Total length 2.10 ( Figs 35C–D View Figure 35 ). Prosoma length 1.00, width 0.71. Dorsal shield of prosoma yellow, with relatively flat cephalic area. Fovea reduced. 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 View Figure 31 , 35A–B View Figure 35 ). Width 0.23. Bursae reduced. Copulatory ducts slender, twisted tightly ( Figs 31A View Figure 31 , 35B View Figure 35 ). Spermathecae slightly swollen, straight.

Male (paratype). Damaged.

Pedipalpus ( Figs 32–34 View Figure 32 View Figure 33 View Figure 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.

Variation. Total length: females 1.95–2.55 (n = 18).

Distribution. Known only from the type locality ( Fig. 97 View Figure 97 ).
