Type material. Holotype: male (IZCAS-Ar41643), Tongguling (19°40.303′N, 111°1.068′E, elevation 337 m), Longlou Town , Wenchang, Hainan, China, 22 March 2012, Z. Chen leg. GoogleMaps Paratypes: 1 male (IZCAS-Ar41644) and 2 females (IZCAS-Ar41645–41646), same data as holotype GoogleMaps .

Etymology. The specific name refers to the type locality and is a noun in apposition.

Diagnosis. This species can be easily distinguished from T. laibin sp. nov. by procursus with sclerotized, narrow and curved ventral apophysis (arrow 2 in Fig. 4C View FIGURE 4 ; absent in T. laibin sp. nov., Fig. 2C View FIGURE 2 ), wide, sclerotized dorsal apophysis with scales (arrow 4 in Fig. 4C View FIGURE 4 ; angular dorsal apophysis without scales in T. laibin sp. nov., arrow 3 in Fig. 2C View FIGURE 2 ), and retrolateral apophysis with scales and pointed sclerite (arrow 5 in Fig. 4C View FIGURE 4 ; two retrolateral processes without scales and sclerite in T. laibin sp. nov., arrows in Fig. 2D View FIGURE 2 ), by male chelicerae with frontal apophyses with scales (arrow in Fig. 5C View FIGURE 5 ; absent in T. laibin sp. nov., Fig. 3C View FIGURE 3 ), by external female genitalia with two postero-lateral apophyses (arrows 1–2 in Fig. 5A View FIGURE 5 ; absent in T. laibin sp. nov., Fig. 3A View FIGURE 3 ), by vulval pore plates anteriorly wide and posteriorly narrow and blunt ( Fig. 5B View FIGURE 5 ; anteriorly wide and posteriorly sharply pointed in T. laibin sp. nov., Fig. 3B View FIGURE 3 ), and by opisthosoma with dorsal and lateral spots ( Figs 5 View FIGURE 5 E–H; with posterior marks in T. laibin sp. nov., Figs 3 View FIGURE 3 E–H).

Description. Male (holotype): Total length 2.03 (2.23 with clypeus), carapace 0.67 long, 0.96 wide, opisthosoma 1.36 long, 0.94 wide. Leg I: – (4.34 + 0.36 + 4.50 + 6.45 + –), leg II: 10.42 (3.16 + 0.35 + 2.78 + 3.02 + 1.11), leg III: 8.48 (2.42 + 0.31 + 2.04 + 2.90 + 0.81), leg IV: 11.05 (3.28 + 0.33 + 2.73 + 3.93 + 0.78); tibia I L/d: 49. Distance PME-PME 0.16, diameter PME 0.11, distance PME-ALE 0.03, AME absent. Sternum slightly wider than long (0.58/0.48). Habitus as in Figs 5 View FIGURE 5 E–F. Carapace yellowish, with brown margins and wide, brown median stripe; ocular area brown; clypeus yellowish, with brown lateral marks; sternum brown. Legs brownish, but slightly whitish on distal parts of femora and tibiae, with distinct darker rings on subdistal parts of femora and proximal and subdistal parts of tibiae. Opisthosoma yellowish, with large, brown, dorsal and lateral spots. Ocular area slightly elevated and separated from rest of carapace. Thoracic furrow shallow, but distinct. Chelicerae ( Figs 5 View FIGURE 5 C–D) with pair of proximo-lateral apophyses (arrow pa in Figs 5 View FIGURE 5 C–D) with lateral apophyses and scales (arrow in Fig. 5D View FIGURE 5 ), pair of frontal apophyses with scales (arrow in Fig. 5C View FIGURE 5 ), and pair of distal apophyses with row of teeth each (arrow da in Figs 5 View FIGURE 5 C–D). Pedipalps as in Figs 4 View FIGURE 4 A–B; trochanter with retrolateral apophysis and ventral apophysis; femur strongly curved dorsally, with retrolateral apophysis; patella large; procursus simple proximally but complex distally, with sclerotized prolatero-ventral apophysis (arrow 1 in Fig. 4C View FIGURE 4 ), sclerotized, narrow and curved ventral apophysis (arrow 2 in Fig. 4C View FIGURE 4 ), sclerotized distal apophysis with scales (arrow 3 in Fig. 4C View FIGURE 4 ), wide, sclerotized dorsal apophysis with scales (arrow 4 in Fig. 4C View FIGURE 4 ), and retrolateral apophysis with scales and pointed sclerite (arrow 5 in Fig. 4C View FIGURE 4 ); bulb simple, without other projections except for embolus. Retrolateral trichobothrium of tibia I at 11% proximally; legs with short vertical setae on metatarsi and tarsi, without spines or curved setae.

Female: Similar to male, habitus as in Figs 5 View FIGURE 5 G–H. Total length 2.28 (2.43 with clypeus), carapace 0.79 long, 0.98 wide, opisthosoma 1.49 long, 1.06 wide; tibia I: 4.48; tibia I L/d: 49. Distance PME-PME 0.15, diameter PME 0.11, distance PME-ALE 0.03, AME absent. Sternum slightly wider than long (0.62/0.52). External female genitalia ( Fig. 5A View FIGURE 5 ) brown, with postero-median apophysis (much longer than wide, arrow ma in Fig. 5A View FIGURE 5 ) provided with pointed tip and two pointed postero-lateral apophyses (arrows 1–2 in Fig. 5A View FIGURE 5 ), without pockets. Vulva ( Fig. 5B View FIGURE 5 ) with curved anterior arch and pair of anteriorly wide and posteriorly narrow and blunt pore plates.

Variation: Tibia I in male paratype: 4.52. Tibia I in another female paratype: 4.56.
