The new species belongs to the hoffi species-group and is characterised by the following combination of characteristics: trichobothria b and sb situated more than one areolar diameter apart; movable chelal finger with upright and point teeth; palpal chela 3.59–3.90 (♀), 3.95 (♂) and palpal hand 1.54–1.75 (♀), 1.68 (♂) longer than broad; palpal femur 0.51–0.54 mm (♀), 0.49 mm (♂), palpal hand 0.33–0.37 mm (♀), 0.32 mm (♂) and chelal movable finger 0.45–0.48 mm (♀), 0.44 mm (♂) long.

Lechytia acutidentata sp. nov. most resembles L. yulongensis due to trichobothria b and sb on movable chelal finger situated more than one areolar diameter apart. However, the new species differs from L. yulongensis in the pattern of teeth of fixed chelal finger with upright and point teeth in L. acutidentata sp. nov., but retrorse and point teeth in L. yulongensis (Zhang and Zhang 2014).

The specific name is derived from a combination of the Latin words “acutus” and “dentatus”, meaning pointed and toothed, respectively, which refers to the pointed teeth on the movable chelal fingers.

China (Xizang Autonomous Region).

All specimens were collected under bark in denser forests (Fig. 6).

Their rounded nests are built by thin silks and had a thicker centre (Fig. 6A and C). Some silk nests are close together, but independent from each other (Fig. 6A).

Generally, the holotypes of Lechytia species are male specimens. Here, we chose a female specimen as the holotype of L. acutidentata, because the sole male specimen has a rather transparent and brittle body. It was probably caught and soaked in alcohol straight after just moulting.

Revised diagnosis (♂♀). The species belongs to the hoffi species-group and is characterised by the following combination of characteristics: trichobothria b and sb situated more than one areolar diameter apart; movable chelal finger with strongly retrorse, pointed teeth; chela 3.45 (♀), 3.55–3.59 (♂) and chelal hand 1.45 (♀), 1.56–1.59 (♂) longer than broad; chelal femur 0.43 mm (♀), 0.40 mm (♂), chelal hand 0.29 mm (♀), 0.27–0.28 mm (♂) and chelal movable finger 0.43 mm (♀), 0.37–0.38 mm (♂) long.

Lechytia yulongensis closest to L. acutidentata sp. nov. due to trichobothria b and sb on movable chelal finger situated more than one areolar diameter apart. However, the species differs from L. acutidentata sp. nov. in the pattern of teeth of fixed chelal finger with retrorse and point teeth in L. yulongensis, but upright and point teeth in L. acutidentata sp. nov (Zhang and Zhang 2014).

China (Yunnan Province).

Lechytia yulongensis was described and illustrated only from male specimens by Zhang and Zhang (2014). Although the original diagnosis contains the following character: trichobothria b and sb are only about one areolar diameter apart (Zhang and Zhang 2014), we found that the distance between trichobothria b and sb is more than one areolar diameter after inspection of the holotype, as shown in the original photo and illustration (Zhang and Zhang 2014: figs. 2C and 4A). In addition, we observed a triangular projection with a single hump on the apex of coxa I in the holotype of L. yulongensis (Fig. 14J), rather than a two-humped projection as shown in the original illustration (Zhang and Zhang 2014: 3A).

The female specimen was collected at the same place as the holotype, they have the same morphological characters, for example, the shape and number of chelal teeth and the positions of trichobothria. Therefore, we described the new specimen as female L. yulongensis. Based on the holotype and the new female specimen, we refined the diagnosis of L. yulongensis (see revised diagnosis) (Zhang and Zhang 2014).
