Type material.

Holotype ♂, China, Yunnan: Nujiang Prefecture, Gongshan County, Pengdang Township, Longpo Village, 12.5 air km of Gongshan (27°85.608'N, 98°68.448'E, 1550 m), 4-7 July 2000, Hengmei Yan leg.

Etymology.

The specific name comes from the Latin hirtella (with macrosetae), referring to the three thick setae on the cymbial tip.

Diagnosis.

This new species resembles Hitobia shaohai Yin & Bao, 2012 (see Yin et al. 2012: figs 631 a–h) in having a similar size of dorsal scutum, retrolateral tibial apophysis bearing a cluster of bristles on the base, but can be separated by: 1) conductor visible in ventral view (Figs 11, 15) versus invisible in Hitobia shaohai ; 2) retrolateral tibial apophysis longer, stronger, the distal end not bifurcated (Figs 11-12, 15-16) versus with two rami in Hitobia shaohai ; 3) opisthosoma dorsum without obvious markings (Fig. 9) versus with one median pale transverse white stripe in Hitobia shaohai ; 4) chelicerae with 3 promarginal teeth (Fig. 14) versus with 2 in Hitobia shaohai .
