The specific name derives from the Latin adjective papillatus and means withbuds, in reference to the embolus with mastoid process GoogleMaps .

Diagnosis. The new species is somewhat similar to T. sangzhiense , but can be distinguished by having the conductor membranous; the embolus with tiny apophyses, the tegular apophysis with an acute tip, and the median apophysis stick-shaped.

Opisthosoma 0.85 long, 0.93 wide, pale, with sclerotized ring around pedicel and spinnerets, with black, white spots, without colulus. Eye measurements: AME 0.09, ALE 0.06, PME 0.06, PLE 0.06, AME-AME 0.04, AME-ALE 0.02, PME-PME 0.04, PME-PLE 0.04. Clypeus height about 2.00 times AME diameter, yellow with black spot. Chelicerae: yellow, with spines, without tooth; fangs long. Endites: 0.18 long, 0.13 wide, yellow, with brown pro-edges. Labium fused with sternum, 0.06 long, 0.13 wide, with 6 setae, pale yellow without spot.

Pedipalpus ( Figs 97A–B View Fig , 98A–B View Fig , 100A–D View Fig ): tibia pale yellow, with 1 trichobothrium; cymbium pale yellow, without spot; paracymbium hooked; subtegulum broad; tegulum confined; median apophysis stick-shaped, without apophysis; embolus short, with tiny apophyses; conductor membranous; tegular apophysis with acute tip.

Female (measurements of paratypes). Total length 1.40–1.55. Prosoma 0.60–0.63 long, 0.50–0.58 wide, flat, yellow, with black stripes, long setae. Sternum 0.36–0.38 long, 0.36– 0.38 wide, pale yellow.
