Genus Hengconarius Z. Zhao & S. Li  gen. n.

Type species. Draconarius exilis Zhang, Zhu & Wang, 2005 

Etymology. The generic name is derived from the pinyin "Heng", referring to the Hengduan Mountains where the genus is distributed and the "- conarius " from Draconarius  . The gender is masculine.

Diagnosis. Hengconarius Z. Zhao & S. Li  gen. n. is similar to Sinodraconarius  , Nuconarius Z. Zhao & S. Li  gen. n. and Draconarius  . But they can be distinguished in details as follows: the new genus can be distinguished from Sinodraconarius  by a patellar apophysis that is never bifurcate and a conductor which is bifurcate; from Nuconarius Z. Zhao & S. Li  gen. n. by the median apophysis not pointed, the conductor with basal lamella and the epigyne with middle septum, the anterior edge of epigyne wrinkled and sclerotized, the posterior edge of epigyne sclerotized; from Draconarius  by the cymbial furrow less than ½ the length of cymbium, the median apophysis slice-shaped, epigynal teeth absent, and the spermathecae simple and not convoluted.

Description. Small to medium-large sized, with total lengths ranging from 6.28 to 12.91. Carapace yellow to tan; radial region with grey-green short setae; Chelicerae with 3 promarginal and 2 retromarginal teeth. Leg formula 4> 1> 2> 3. Male palp: patellar apophysis present or reduced; two tibial apophyses: retrolateral tibial apophysis broad and slice-shaped; lateral tibial apophysis small, whose length and width about ⅓ of the length and width of retrolateral tibial apophysis, respectively; cymbial furrow short, less than ½ the length of cymbium; embolic base beginning at about 8 o’clock position; conductor befurcate, with a small basal lamella and a conductor’s dorsal apophysis; median apophysis thin, usually slice-shaped. Epigyne: epigynal teeth absent; the anterior edge of epigyne wrinkled and sclerotized; the posterior edge of epigyne sclerotized; the shape of atrium variable; epigynal hoods located anterolaterally; copulatory openings located centrally; copulatory duct extends horizontally; spermathecae simple and separated, the distance between spermathecae subequal to the diameter of spermatheca; spermathecal heads located at anterolaterally or in the middle.

Natural history. Species of Hengconarius Z. Zhao & S. Li  gen. n. were all collected by hand or trapping

methods. They were found in moist and gloomy places in the highlands (1881–4089 m), such as under stones, rocks and in leaf-litter.

Composition. So far eight species are considered in the new genus: H. dedaensis Z. Zhao & S. Li  sp. n., H. exilis ( Zhang, Zhu & Wang, 2005)  comb. n., H. falcatus ( Xu & Li, 2006)  comb. n., H. incertus ( Wang, 2003)  comb. n., H. latusincertus (Wang, Griswold & Miller, 2010)  comb. n., H. longipalpus Z. Zhao & S. Li  sp. n., H. longpuensis Z. Zhao & S. Li  sp. n. and H. pseudobrunneus ( Wang, 2003)  comb. n.

Distribution. Sichuan, Tibet and Yunnan, China ( Fig. 20 View Figure ).
