Talaus dulongjiang Tang et al., 2008: 63, figs 1-12.

Type material examined.

Paratypes. 2 ♂ (DHK-2004-068): China, Yunnan. Province, Gongshan County, Dulongjiang Township, 2.3-3.3 km south of Longyuan Village along Dulongjiang, 28.00532°N, 98.32145°E, 1685 m, 2 November 2004, David Kavanaugh leg. (Tho-159, paratypes examined, HNU); 4 ♀ (Tang-04-08), Mokewang Bridge, 27.83827°N, 98.32103°E, 1455 m, 6-7 November 2004, Guo Tang leg., other data same as previous (Tho-159). Holotype not examined.

Diagnosis.

The male of this species is similar to T. niger Tang, Yin, Ubick & Peng, 2008 (Tang et al. 2008: 65, figs 16-18) in having the same position of the tegular ridge and the filiform embolus, but can be separated from it by the retrolateral tibial apophysis strongly bending forward (vs slightly) and the longer ventral tibial apophysis (vs relatively short) (Fig. 1C-F). The females can be easily separated from T. niger (Tang et al. 2008: 65, fig. 20) by the helical copulatory duct (vs S-shaped) and the slightly separated swollen spermathecae (vs clearly separated) (Fig. 2D).

Description.

Male habitus as in Fig. 1A, B, palp in Fig. 1C-F. Palp: tibia with two apophyses, the ventral one slightly shorter than retrolateral one, but longer than tibia, with a strongly curved apex directed prolaterally; retrolateral one relatively thin, basally slightly curved antero-retrolaterally in ventral view, longer than tibia; tegular ridge long, basally arising from ~ 12 o’clock position of the tegulum; embolus filiform, spiraling nearly 3/4 coil, arising from 3 o’clock and ending at ~ 1 o’clock on tegulum. Female habitus as in Fig. 2A, B, epigyne in Fig. 2C, D. Epigyne: copulatory openings relatively large, sub-antero-laterally located; copulatory ducts broad and long, looping 1.75 coils; spermathecae swollen, slightly separated by ~ 1/7 of their width; fertilization ducts located posteriorly, directed anterolaterally.

Distribution.

Known from Yunnan Province, China (Fig. 12).

Remarks.

According to Tang et al. (2008) the original material consisted of three males and seven females; two males and four females were deposited in HNU and one male and three females in CAS. However, only two males and four females (but not the holotype) were found in HNU and there are no striking markings on them: the label data match the localities of the paratypes recorded by Tang et al. (2008: 63).
