Pinelema Wang and Li 2012: 76; Wang and Li 2016: 547; Zhao et al. 2018a: 14; Zhao et al. 2018b: 10.

Type species.

Pinelema bailongensis Wang & Li, 2012 from Guangxi, China.

Diagnosis.

Pinelema can be distinguished from Telema by the following: belt-shaped tibial glands (arrows on Fig. 1B ) (vs. plate-shaped), the presence of a cymbial apophysis (vs. absent), and the triangular, trapezoidal, or tube-like embolus (vs. duckbill shaped). The endogyne is extended distally (vs. no extension).

Description.

Total length: 1.07-1.77 (male), 1.20-2.02 (female). Carapace 0.48-0.82 long. Sternum with several long setae. Six eyes ringed with black, vestigial, or completely absent in some species. Legs thin, long relative to body. Leg formula: 1-2-4-3. Tibia I 0.94-2.20 long, glands of legs belt-shaped (Fig. 1B ). Cymbial apophysis distinct, bulb large relative to body, oval, kidney-shaped, droplet-shaped, etc.; embolus triangular, tube-shaped, needle-shaped, etc., embolus short, medium, or long relative to cymbium. Receptacle with several membranous tubes inside and typically swollen distally.

Distribution.

China (Guangxi, Guizhou, Yunnan, Hainan), Laos (Vien Tiane), and Vietnam (northern and central Vietnam) (Figs 30 - 32 ).

Comments.

All 26 new combinations are supported by morphological characters, such as the presence of a cymbial apophysis and the extended tip of the receptacle. Including the new species described in this paper increases the total number of Pinelema species to 54, making it the most speciose genus in Telemidae .

Composition.

According to the morphological characters of the male palp, 54 Pinelema species have been divided into seven species groups as well as six species not attached to a species group. The composition of species groups is discussed below.
