Type locality.

Russia, the Kabardino-Balkarian Republic, central Greater Caucasus, right tributary of Dongoserun (Donguz-Orun-Baksan) River (2100 m a.s.l.).

Distribution.

Georgia, south-western Russia. Species endemic to the Greater Caucasus (Fig. 24 View Figure 24 ).

Habitat.

Larvae inhabit small streams and rivers at middle and high altitude in the western and central Greater Caucasus. Altitudinal range of sampling sites 760-2580 m a.s.l. (Fig. 24 View Figure 24 ). Most frequently found above 1800 m a.s.l. Often syntopic with E. (C.) alpestris   and at lower altitude with E. (C.) soldani   .

Main morphological diagnostics of larvae.

(i) abdominal terga V-VII with narrowed triangular medial macula and a pair of anterolateral spots (Fig. 25H View Figure 25 ; arrows); (ii) abdominal sterna without coloration pattern (Fig. 25B, I View Figure 25 ); (iii) femora without medial hypodermal spot (Fig. 25F, G View Figure 25 ); (iv) gill plates VII (in natural position from ventral view) narrow (Figs 25J View Figure 25 , 26H-K View Figure 26 ); (v) gill plates III with poorly developed projection (Fig. 26G View Figure 26 ); (vi) setae on abdominal terga not distinctly wide at base, often elongated (Fig. 26E View Figure 26 ); (vii) tergum X without postero-lateral projections (Fig. 26L View Figure 26 ).

Remarks.

Taxonomy. Original description based on male imago and larva from the Greater Caucasus ( Braasch and Zimmermann 1979). The type series is currently deposited in SMNS. Female imago not described in detail. The association of imagines and larvae based on the colour pattern of abdominal terga and sterna in material from the same locality.
