Otacilia flexa sp. nov. Figs 16 A–J, 17A–E Type material. Holotype ♂, China, Yunnan Province, Funing County, Muyang National Public Ecological Forest, 23°27.107′N, 105°25.373′E, 7 May 2011, Zongxu Li leg. Paratypes: 5♂, 8♀, same data as for holotype, Zongxu Li & Guchun Zhou leg. Etymology. The species name is derived from the Latin word ‘ flexus ’ and refers to the folded copulatory ducts; adjective in genitive case. Diagnosis. The new species is similar to O. longituba (Wang et al. 2012: 41, figs 4A–E, 5A–I), but can be distinguished from it by: 1) CO large, anteriorly, widely separated (Figs 16 C, 17D) (smaller, located relatively posteriorly and close to each other in O. longituba); 2) boomerang-shaped BU (Figs 16 D, 17E) (racket shaped in O. longituba); 3) DTA trifurcated apically (Figs 16 E, 17C) (broad, with a relatively narrow base in O. longituba); 4) a longer spoon-shaped conductor (Figs 16 G, 17B) (short in O. longituba). The new species is also similar to O. mira sp. nov. (Figs 1–2), but can be distinguished from the latter by: 1) DTA trifurcated apically (Figs 16 E, 17C) (Sshaped, with relatively sharp apex in O. mira sp. nov.); 2) conductor present (absent in O. mira sp. nov.); 3) boomerang-shaped BU (Figs 16 D, 17E) (hilt-like in O. mira sp. nov.); 4) SP larger (small in O. mira sp. nov.). Description. Male (Fig. 16 A). Total length 1.93–2.42 (n=6). Holotype: body 2.33 long; carapace 1.03 long, 0.92 wide; abdomen 1.19 long, 0.83 wide. Carapace light yellowish.

Chelicerae with one strong anterior bristle; promargin with three well-separated teeth and retromargin with two teeth close to each other. Labium and gnathocoxae yellow. Legs light yellow. Leg measurements: leg I 2.84 (0.88, 0.26, 0.79, 0.58, 0.33), II 2.28 (0.69, 0.22, 0.52, 0.49, 0.36), III 2.19 (0.58, 0.25, 0.43, 0.52, 0.41), IV 3.13 (0.86, 0.28, 0.71, 0.76, 0.52). Abdomen dark grey, with anterior large dorsal scutum occupying nearly 4/5 of abdomen length; posterior half with six bright chevron-shaped markings dorsally. Venter yellow grey. Palp (Figs 16 E–H, 17A–C): DTA strong, relatively thick, with wide base, trifurcated apically. Tibia wider than femur and patella. E long, tapering, needle-like, without PEA. SD strongly sclerotized. Conductor long, spoonshaped, its tip close to tip of E. Female (Fig. 16 B). Total length 2.46–2.76 (n=4). One paratype: body 2.51 long; carapace 1.04 long, 0.90 wide; abdomen 1.42 long, 0.92 wide. Carapace light yellowish. Eyes sizes and interdistances: AME 0.04, ALE 0.07, PME 0.05, PLE 0.06; AME–AME 0.02, AME–ALE 0.01, PME–PME 0.05, PME–PLE 0.05. MOA 0.12 long, front 0.09 wide, back 0.16 wide. Clypeus 0.08 high. Leg measurements: I 2.80 (0.78, 0.28, 0.77, 0.63, 0.34); II 2.50 (0.76, 0.26, 0.48, 0.54, 0.44); III 2.37 (0.68, 0.23, 0.48, 0.54, 0.44); IV 3.39 (0.93, 0.29, 0.78, 0.84, 0.55). Abdomen light grey dorsally, without dorsal scutum; posterior half with seven light chevron-shaped markings dorsally. Epigyne (Figs 16 C–D, 17D–E): CO large, widely separated, by distance equal to double their diameter. CD with two folds, connected to two large, transparent, boomerang-shaped BU anteriorly. SP round, large, located posteriorly, close to each other. FD originating anteriorly from SP. Distribution. Known only from the type locality, Yunnan, China (Fig. 18).
