Material examined.

China: Sichuan: 2♂, Mt. Emei, Yuanhong Cave, 29°34'08"N, 103°24'32"E, 858 m, 29.IX.2016, Z. Zhao & X. Zhang; 2♀5♂, Mt. Emei, 29°34'11"N, 103°25'36"E, 834 m, 29.IX.2016, Z. Zhao & X. Zhang.

Diagnosis.

The male can be distinguished from all other Pireneitega species except P. involuta and P. liansui by having a broad conductor, the width of the conductor is about 1/5 of the loop diameter. From P. involuta it can be distinguished by the embolus base, beginning at the 6:00 o’clock position (vs beginning at the 6:30 o’clock position in P. involuta ). From P. liansui it can be distinguished by the tapering tip of the patellar apophysis (vs a bifurcate tip in P. liansui ). (Figs 3, 7; Wang et al. 1990: figs 13-15, 18-19). The female can be distinguished from all other Pireneitega species except P. involuta and P. liansui by having a bent and longer receptacle. From P. involuta it can be distinguished by a short septum. From P. liansui it can be distinguished by narrow epigynal teeth and the tapering tip of the septum (vs broad epigynal teeth and a blunt of septum tip in P. liansui ) (Figs 4, 8; Wang et al. 1990: figs 16-17).

Leg measurements: I: 15.75 (4.50, 5.25, 4.00, 2.00); II: 14.00 (4.25, 4.50, 3.50, 1.75); III: 12.45 (3.75, 4.10, 3.00, 1.60); IV: 16.30 (4.75, 5.25, 4.30, 2.00). Carapace brown, radial grooves indistinct. Abdomen yellow with black herringbone pattern. Palp as in Fig. 7: patellar apophysis long, more than half length of tibia, with tapering tip; tibia short, about the same length as cymbium; VTA subequal to the tibial length, without pointed tip, extending beyond the tibia; RTA short, about 1/8 length of VTA; cymbial furrow short, about 1/3 length of cymbium; width of conductor about 1/5 of loop diameter; embolus with broad base, beginning at the 6:00 o’clock position.

Female: Total length 9.75. Carapace 5.00 long, 4.00 wide. Abdomen 4.75 long, 3.50 wide. Eye sizes and interdistances: AME 0.25, ALE 0.20, PME 0.25, PLE 0.20; AME-AME 0.10, AME-ALE 0.10, PME-PME 0.20, PME-PLE 0.25. Leg measurements: I: 14.00 (4.50, 4.75, 3.25, 1.50); II: 13.20 (4.20, 4.50, 3.00, 1.50); III: 12.05 (4.00, 4.00, 2.80, 1.25); IV: 14.50 (4.75, 4.75, 3.50, 1.50). Carapace yellow. Abdomen black with yellow spots and herringbone pattern. Epigyne as in Fig. 8 A–B: epigynal teeth narrow and short about 0.9 of atrium length; septum with well sclerotized tip; atrium with weakly delimited posterior margin, about 3.3 times longer than septum, about 1.9 times wider than septum; copulatory opening distinct; receptacle narrow and long, about five times longer than wide, separated by the diameter of receptacle; median part of copulatory ducts as wide as terminal and 1.5 times longer than basal part, median part about three times wider than receptacle; hoods distinct.

Spination in female:

Distribution.

Known only from Sichuan (Fig. 11).

Note.

The DNA barcode of the male described here matches that of the female. In the original species description of Coelotes triglochinatus , the female holotype and male ‘allotype’ were not correctly matched ( Wang and Jäger 2007). The male ‘allotype’ of C. triglochinatus might match the female of other Coelotinae species described from Mt. Emei. Currently, two Coelotinae species described from Mt. Emei are known only by females, they are Draconarius sichuanensis Wang & Jäger, 2007 and Platocoelotes imperfectus Wang & Jäger, 2007 ( World Spider Catalog 2017).
