Treatment

Brommella funaria Li View in CoL , sp. nov. ( Figs 16–20 View Figure 16 View Figure 17 View Figure 18 View Figure 19 View Figure 20 , 97 View Figure 97 )

Type material. Holotype. Male, China, Guangxi, Yizhou City, Yankou Village , Xiannüyan Cave , 24º29.319'N, 108º34.205'E, elev. 205 m, 28 July 2009, C. Wang & Z. Yao leg., deposited in IZCAS GoogleMaps . Paratypes. 6 males, 7 females, same data as holotype, deposited in IZCAS GoogleMaps .

Etymology. The specific name is derived from the Latin word “ funarius ”, meaning “of a rope”, and refers to the shape of the copulatory ducts; adjective.

Diagnosis. Males of this new species are similar to B. yizhouensis Li , sp. nov. ( Figs 57–61 View Figure 57 View Figure 58 View Figure 59 View Figure 60 View Figure 61 ), but can be distinguished by the 8-o’clock position of the base of the embolus (originating approximately at the 10-o’clock position in B. yizhouensis Li , sp. nov.). Females of this new species are similar to B. tongyanfengi Li , sp. nov. ( Figs 45–49 View Figure 45 View Figure 46 View Figure 47 View Figure 48 View Figure 49 ), but can be distinguished by the copulatory ducts twisted as two short ropes in ventral view (copulatory ducts twisted loosely and irregularly in B. tongyanfengi Li , sp. nov.).

Description. Male (holotype). Total body length 1.90 ( Fig. 20E View Figure 20 ). Prosoma length 0.90, width 0.70. Cephalic region width 0.45. Dorsal shield of prosoma yellow, cephalic region relatively flat, covered with several setae. Fovea reduced. Cervical groove indistinct. Six eyes, AME reduced to small pigment spots, all eyes white, encircled with black. Eye sizes and interdistances: ALE 0.07, PLE 0.07, PME 0.05; ALE-PLE 0.01, PLE-PME 0.03, PME-PME 0.06, ALE-ALE 0.08. Eye region length 0.17, width 0.32. Clypeus height 0.10. Chelicerae length 0.40, width 0.19. Chelicerae with distinct lateral condyles, 3 promarginal and 5 retromarginal teeth. Labium and gnathocoxae yellow-brown; sternum yellow. Labium length 0.13, width 0.18. Gnathocoxae length 0.31, width 0.18. Sternum length 0.58, width 0.53. Legs yellow. Leg formula I-IV-II- III. Leg measurements: I 4.41 (1.25, 0.33, 1.25, 0.93, 0.65); II 3.63 (1.03, 0.30, 0.85, 0.85, 0.60); III 3.29 (0.90, 0.33, 0.78, 0.75, 0.53); IV 4.11 (1.20, 0.33, 1.00, 1.00, 0.58). Ratio Cl/Met IV =0.38, with 7 setae. Opisthosoma length 0.95, width 0.68, white, without distinct pattern. Cribellum narrow, undivided.

Pedipalpus ( Figs 16–17 View Figure 16 View Figure 17 , 19 View Figure 19 ). Cymbium 0.40 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 large bifurcated spur.

Female (one of the paratypes). Total body length 2.05 ( Figs 20C–D View Figure 20 ). Prosoma length 0.90, width 0.65. Cephalic region width 0.40. Eye sizes and interdistances: ALE 0.06, PLE 0.07, PME 0.04; ALE-PLE 0.01, PLE-PME 0.03, PME-PME 0.06, ALE-ALE 0.09. Eye region length 0.15, width 0.27. Clypeus height 0.08. Chelicerae length 0.39, width 0.20. Chelicerae with distinct lateral condyles, 3 promarginal and 4 retromarginal teeth. Labium length 0.13, width 0.18. Gnathocoxae length 0.30, width 0.18. Sternum length 0.53, width 0.45. Leg formula I-IV-II-III. Leg measurements: I 3.88 (1.13, 0.35, 1.00, 0.85, 0.55); II 3.25 (1.00, 0.35, 0.75, 0.70, 0.45); III 2.80 (0.85, 0.25, 0.60, 0.65, 0.45); IV 3.66 (1.10, 0.30, 0.88, 0.88, 0.50). Ratio Cl/Met IV = 0.26, with 7 setae. Opisthosoma length 1.15, width 0.85, without distinct pattern.

Variation. Total body length: males 1.6–1.9 (n = 7), females 1.80–2.50 (n = 7).

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