Type material. Holotype: ♁ together with paratypes 1♁ and 2♀ ( ZMMU) from UZ- BEKISTAN: Namangan Province , Pap District , SE foothills of Kurama Mountains , ca. 5-5.5 km NW of Khanabad, ca. 850 m a.s.l., 40°54’05”N 70°45’44”E, 16.05.2002, A.V. Gromov coll.; paratype 1♁, Namangan Province , Pap District, SE foothills of Kurama Mountains, ca. 5.5 km NW of Khanabad, ca. 380 m a.s.l., under stones, 40°54’15”N 70°45’29”E, 15.05.2002, A.V. Gromov coll. ( SMF).

Etymology. The species name is a patronym honoring our friend and colleague Sergei Esyunin of Perm, Russia.

Diagnosis. H. esyunini sp. n. is closely related to H. xinjiangenis , from which it can be distinguished by its smaller size, differently shaped tegular apophysis and the median plate of the epigyne. From all congeners H. esyunini sp. n. can be easily distin- guished by a relatively shorter tip of the cymbium, undivided tegular apophysis and a median plate of the epigyne with turned up lateral edges of the median plate.

Description. Male. Total length 3.4-3.65. Carapace 1.4-1.5 long, 1.5-1.6 wide, femur I 3.0-3.1 long, femur/carapace length ratio 2.1-2.14. Body yellow-light brown with pattern formed by brown hairs and spots. Carapace with brownish eye area and posterior cephalic part, and brown vertical stripe on clypeus (Figs 1.2, 2.2). Margins of carapace brown. Abdomen with indistinct pattern. Legs with broad, dark annulations, dark rings wider than light ones. Femur I almost entirely dark. Coxae IV separated by one diameter. Palp as in Figs 3.1, 4.4, 5.4, 6.6-7, with femur, patella+tibia and cymbium subequal in length, tibia in terminal part slightly wider than femur. Tegulum discoid, with long filiform embolus and tegular apophysis. Embolus starts at about 01 hrs, makes a loop of more than 270° and terminates around 10 hrs. Tegular apophysis perpendicular to tegulum. Apical part of the bulb slightly flattened (embolus straight, not rounded).

Female. Total length 3.75-4.0. Carapace 1.4-1.5 long, 1.5-1.6 wide, femur I 2.25- 2.5 long, femur/carapace length ratio 1.6. Colouration as in female. Epigyne as in Figs 7.10-12, 8.4. Median plate anchor-like, with a pair of small accessory sclerites on the side that visually makes the basal part wider; spermathecae and seminal duct translucent through the integument. Accessory gland digitiform.

Comments. Earlier, Marusik (2009) confused this species with the related H. xinjiangensis due to the similarity of their male palps, i.e. same shape of the apical part of the tegulum (character unknown in other Hersiliola species), same position of the embolic tip, and same shape of the tegular apophysis. Misidentification was made before we started this revision of East Palaearctic Hersiliola .

Distribution. The species is known only from two nearby localities in eastern Uzbekistan.
