Diagnosis (male, female unknown). This new species is distinguished from other members of the genus Stenohya by the following combination of characters: pedipalpal femur with one distal tubercle (many small bulges) and one basal tubercle on prolateral face, hand with 42 tooth-shaped tubercles (retrolateral view). Fixed finger with 94 small cusped teeth, movable finger with 89 teeth. Pedipalpal femur 4.25× longer than broad, length 1.64 mm; chela (with pedicel) 5.19× longer than broad, length 2.93 mm; ratio movable chelal finger/chelal hand (with pedicel) 1.40×.

Etymology. Latinised adjective, derived from the type locality, namely Jiahe Garden.

Description. Carapace, chelicerae and abdomen brown, remaining parts yellowish brown.

Fixed finger with 94 small cusped teeth, movable finger with 89 teeth; venom duct in fixed finger, very short. Fixed chelal finger with eight trichobothria and movable finger with four trichobothria, eb, esb, ib and isb located basally of the fixed finger; et, est, it (retrolateral view) and ist (prolateral view) situated distally, et distinctly closer to fingertip than to it; on movable finger, b and sb located basally, t and st situated distally.

Abdomen: tergal chaetotaxy (I–XI): 6: 8: 8: 9: 11: 10: 11: 11: 11: 11: 7; sternal chaetotaxy (IV–XI): 29: 18: 14: 19: 15: 15: 12: 9; anal cone with two dorsal and two ventral setae. Tergite XI with two tactile setae. Manducatory process with five setae. Pedipalpal coxa with 14 setae, coxa I 7, II 8, III 8, IV15 setae. Anterior genital operculum with 27 setae and without lyrifissures; posterior operculum with 25 setae, two lyrifissures (Fig. 2D). Sternites V 2, VI 13, VII 13, VIII 11 medial scattered glandular setae (Fig. 2C).

Legs: Leg I: trochanter 1.08× longer than deep, femur 3.09× longer than deep and 1.01× longer than patella, patella 3.09× longer than deep, tibia 4.16× longer, basitarsus 3.14× longer, telotarsus 4.50× longer than deep, telotarsus 1.06× longer than basitarsus. Leg IV: trochanter 2.62× longer than deep, femur + patella 3.71× longer than deep, femur shorter than patella, tibia 7.24× longer than deep, basitarsus 4.41× longer, telotarsus 7.34× longer than deep. Tactile setae probably present (most setae lacking) on basitarsus (near basally of segment), telotarsus with 2 tactile setae (basally, TS = 0.25; distally, TS = 0.43), subterminal seta forked, arolia shorter than claws.
