Type locality.

Russia, The Karachay-Cherkess Republic, western Greater Caucasus, Teberda (Glacier Alibek - stream, 1800-1900 m a.s.l.).

Distribution.

Georgia, south-western Russia. Species endemic to the Greater Caucasus (Fig. 18 View Figure 18 ).

Habitat.

Larvae inhabit small streams and rivers at middle and high altitudes in the western and central Greater Caucasus. Frequently found above 1000 m a.s.l. Altitudinal range of sampling sites 426-1900 m a.s.l. (Fig. 18 View Figure 18 ). Often syntopic with E. (C.) alpestris   and E. (C.) sinitshenkovae   .

Main morphological diagnostics of larvae.

(i) abdominal terga V-VII with well-defined triangular medial maculae (Fig. 19H, I View Figure 19 ); (ii) abdominal sterna II-VI either without pattern or with indistinct pattern as on Fig. 19J, K View Figure 19 ; (iii) setae on abdominal terga wide at base (Fig. 20E View Figure 20 ); (iv) femora without medial hypodermal spot (Fig. 19F, G View Figure 19 ); (v) tergum X without postero-lateral projections (Fig. 20L View Figure 20 ); (vi) gill plates III with well-developed projection (Fig. 20G View Figure 20 ); (vii) gill plates VII (in natural position of ventral view) narrow (Figs 19L View Figure 19 ; 20H-K View Figure 20 ); (viii) denticles along posterior margin of tergum VII relatively sparse and triangular (Fig. 20E View Figure 20 ).

Remarks.

Taxonomy. This species was described based on male imago and larva from the western Greater Caucasus ( Braasch 1979). The type series is currently deposited in SMNS. Larva associated with imago based on the coloration of abdomen. Female imago not described. The lineage Caucasiron   sp. 7 detected by Hrivniak et al. (2020b) is distributed in Georgia and morphologically corresponds to E. (C.) soldani   . Therefore, E. (C.) soldani   may represent a species complex.
