 Description. Body elongate, nearly parallel-sided (Figs. 1–2), 2.05–2.16 (2.11) times as long as wide in JJ and 2.13 times as long as wide in ♀. Body length 3.45–3.79 (3.74) mm in JJ and 4.26 mm in ♀.   
Head brown and anteriorly lighter in J and completely light brown in ♀; densely punctate with light pubescence, hairs directed anteriorly. Labrum light brown, maxillary palpi light brown. Antennomeres 1–3 light brown, remaining ones blackish-brown (J), in ♀ also base of antennomere 4 somewhat lighter. Lengths of antennomeres 1–4: 0.20 mm, 0.07 mm, 0.04 mm and 0.35 mm in J and 0.18 mm, 0.09 mm, 0.05 mm and 0.35 mm in ♀.  
Pronotum plain yellowish-brown (Figs. 1, 2); strongly punctate, with light vestiture, hairs directed laterally and posteriorly. Posterior corners distinctly explanate, anterior margin broadly rounded. LP 0.74–0.88 (0.79) mm in J and 0.88 mm in ♀. BP 1.13–1.25 (1.19) mm in J and 1.38 mm in ♀.  
Scutellum light brown, shallowly punctate. Elytra brown, around scutellum as well as at lateral margins behind humeri and at apex infuscate, humeri consequently light (Fig. 1), dark coloration less developed in ♀ (Fig. 2); elytra with dense light vestiture. BE 0.84–0.94 (0.87) mm in J and 1.00 mm in ♀; LE 2.71–3.09 (2.95) mm in J and 3.38 mm in ♀.  
Legs light brown. Ventral surface brown. Sternites brown, infuscate in the middle.  
Male. Sternite 7 with parabolic, 0.06–0.07 (0.07) mm deep emargination (Fig. 3); 0.45–0.52 (0.50) mm long and 0.95–1.08 (1.01) mm wide. Tergite 7 plate-shaped, with bacilla lateralia (Fig. 4); 0.49–0.58 (0.53) mm long. Plate 0.70–0.72 (0.71) mm wide and 0.35–0.42 (0.39) mm long in the middle; bacilla lateralia (irrespective of curvature) 0.34–0.40 (0.36) mm long.  
Sternite 8 (Fig. 5) with large, posteriorly broadly rounded pterygia; 0.56–0.62 (0.59) mm long and 0.45–0.50 (0.48) mm wide. Stalk narrow, 0.27–0.30 (0.28) mm long and posteriorly 0.06–0.07 (0.06) mm broad, bifurcate and strengthening base of pterygia. Narrow rod-shaped sclerotization in the middle reaching base of pterygia (arrow). Tergite 8 (Fig. 6) with sclerotized, posteriorly shallowly emarginate plate (emargination 0.02–0.03 mm deep) and heavily sclerotized bacilla lateralia. Tergite 0.67–0.74 (0.71) mm long; plate 0.49–0.53 (0.51) mm wide; bacilla lateralia (irrespective of curvature) 0.51–0.57 (0.54) mm long.  
Tergite 9 with sclerotized bacilla lateralia, plate little sclerotized posteriorly. Tergite ca. 0.60–0.65 mm long; plate 0.27–0.31 mm (0.29 mm) wide; bacilla lateralia (irrespective of curvature) 0.40–0.50 (0.45) mm long. Sternite 9 (Fig. 7) with area of longer setae posteriorly, lateral margin strengthened, the strengthened borders interconnected by fine membrane anteriorly. Sternite 0.80–0.87 (0.83) mm long; plate 0.26–0.32 (0.29) mm wide.  
Tegmen (Fig. 8) with parameres straight, broad at base and gradually tapering, projecting posteriorly into distinctly detached, knife-shaped, 0.05–0.07 mm long tips (Fig. 9) with transverse structure near the tip (arrow). Tegmen 0.81–0.92 (0.86) mm long and 0.18–0.19 (0.19) mm wide.  
Penis slender, 1.11–1.18 (1.14) mm long and 0.12–0.13 (0.13) mm wide; slenderness index 8.5–9.4 (9.0). Parameroids 0.21–0.22 (0.22) mm long, posteriorly with well defined lateral tooth (up to apex 0.06 mm long), densely covered with sensory pores (Fig. 10).  
Female. Sternite 7 with rectilinear posterior margin (Fig. 11), 0.53 mm long and 1.16 mm wide. Tergite 7 developed as membranous plate with more sclerotized anterolateral areas (Fig. 12, arrow). Bacilla lateralia with a loop-like structure slightly behind their midlength (arrow). Tergite 0.65 mm long; plate 0.60 mm wide and in the middle 0.40 mm long; bacilla lateralia (irrespective of curvature) 0.40 mm long.

 Etymology. This new species is dedicated to Josef Jelínek, a long-standing curator of Coleoptera in the National Museum, Prague, with whom we are united by a bond of friendship lasting tens of years.   
 Distribution. Currently known only from the type locality, Aman Kutan in Uzbekistan, ca. 40 km south of Samarkand (39°19′N, 66°56′E).
