Etymology. The specific name is dedicated to the cat, Mr. Yumao, that belongs to Qianhui Zeng; noun (name) in genitive case.
Diagnosis. The new species is similar to
U. rubra
Deeleman-Reinhold, 2001
by the expanded middle part of the retrolateral tibial apophysis. However, the new species can be distinguished from
U. rubra
by the straight retrolateral tibial apophysis (
vs.
curved in
U. rubra
).
Description. Male (
holotype
). Total length 5.69; carapace 2.79 long, 2.08 wide, opisthosoma 2.90 long, 1.96 wide. Eye sizes and interdistances: AME 0.15, ALE 0.17, PME 0.15, PLE 0.16, AME–AME 0.08, AME–ALE 0.10, PME–PME 0.22, PME–PLE 0.32, AME–PME 0.16, ALE–PLE 0.25. Chelicerae with three promarginal and four retromarginal teeth. Leg measurements: I 8.10 (2.43, 3.09, 1.67, 0.91), II 7.46 (2.10, 2.79, 1.66, 0.91), III 5.30 (1.53, 1.71, 1.39, 0.67), IV 6.56 (1.81, 2.22, 1.76, 0.77).
Coloration (

Dorsum gray, with two pairs of muscle impressions, a light median band. Venter colored as dorsum, median area with pair of dark longitudinal bands, with scattered irregular black spots.
