Schmidt (all specimens in BKDC).   
 Redescription. Body elongate, subparallel-sided (Fig. 23), 2.14–2.33 (2.26) times as long as wide. Body length 4.40–5.22 (4.74) mm.   
Head brown to reddish-brown, densely punctate, with light vestiture, hairs directed anteriorly. Labrum and maxillary palpi light brown. Antennomeres 1–3 brown, rest of antennae blackish-brown. Lengths of antennomeres 1–4: 0.22 mm, 0.11 mm, 0.04 mm and 0.45 mm.  
 eberti n = 2, E. jelineki n = 1.   
Pronotum monochrome, brown to reddish-brown (Fig. 23); strongly punctate, vestiture light, hairs directed laterally and posteriorly; posterior angles distinctly explanate, anterior margin broadly rounded. LP 0.89–1.10 (0.96) mm; BP 1.44–1.66 (1.52) mm.  
Scutellum reddish-brown, shallowly punctate. Elytra brown, suture, lateral margins and apex to various extent blackish-brown (Fig. 23); densely punctate and with dense light vestiture; longitudinal ridges distinctly developed. BE 1.03–1.12 (1.06) mm; LE 3.50–4.12 (3.84) mm.  
Legs light brown. Anterior tibiae near base with angulate extension. Sternites blackishbrown.  
Male. Sternite 7 posteriorly with subtriangular, 0.11–0.14 (0.12) mm deep emargination (Fig. 24); 0.61–0.65 (0.64) mm long and 1.24–1.29 (1.27) mm wide. Tergite 7 plate-shaped, with bacilla lateralia. Tergite 0.68 mm long; plate 0.90 mm wide and in the middle 0.53 mm long; bacilla lateralia (irrespective of curvature) 0.50 mm long.  
Sternite 8 (Fig. 25) with large, posteriorly rounded pterygia. Stalk narrow, in the middle with narrow rod-shaped sclerotization reaching just the base of pterygia; stalk bifurcated laterally at base, strengthening pterygia. Sternite 0.72–0.82 (0.77) mm long and 0.56–0.62 (0.59) mm wide; stalk up to base of pterygia 0.45–0.56 (0.51) mm long. Tergite 8 (Fig. 26) with sclerotized, posteriorly almost straight plate and heavily sclerotized bacilla lateralia. Tergite 0.81–0.95 (0.88) mm long; plate 0.60–0.68 (0.64) mm wide; bacilla lateralia (irrespective of curvature) 0.62–0.65 (0.63) mm long.  
Tergite 9 with sclerotized bacilla lateralia, plate posteriorly weakly sclerotized. Tergite ca. 1.05 mm long; plate 0.40–0.48 (0.46) mm long; bacilla lateralia (irrespective of curvature) 0.50–0.52 (0.52) mm long. Sternite 9 with patch of longer setae posteriorly, lateral margins strengthened, interconnected by fine membrane. Sternite 1.11–1.30 (1.20) mm long; plate 0.33–0.38 (0.35) mm wide.  
Tegmen (Fig. 27) with parameres gently curved outwards, broad at base and projecting distally in a distinctly detached, 0.12–0.13 (0.13) mm long tip (Fig. 28). Tegmen 1.47–1.60 (1.53) mm long and 0.21–0.31 (0.26) mm wide.  
Penis slender, 1.80–1.90 (1.86) mm long and 0.14–0.28 (0.21) mm wide; index of slenderness 6.40–13.60. Parameroids 0.35–0.42 (0.39) mm long, posteriorly with well defined lateral tooth, behind it narrowly elongate (up to apex 0.08–0.13 mm long), densely covered with sensory pores (Fig. 29).  
Female. Unknown.  
 Notes. Elodes orientalis Iablokoff-Khnzorian, 1973 was considered as a synonym of Elodes eberti Klausnitzer, 1970 by KLAUSNITZER (1974) because the original description was insufficient and the type specimens could not be revised. Now, freshly available specimens make possible a better interpretation of the data by IABLOKOFF- KHNZORIAN (1973). Especially the shape of the parameroids suggests the appurtenance of the specimens to E. orientalis and the other characters do not contradict this conclusion.   
IABLOKOFF- KHNZORIAN (1973) gives the type locality as ‘ Tadzhikistan, upper stream of Surkhob, gorge Maidan-Tau’ (supposedly Sarinay on Surkhob near the boundary with Kirgizia). The geographic coordinates of this locality are 39°24′N and 71°41′E.
