status

 

Epeorus (Caucasiron) zagrosicus Hrivniak & Sroka, 2020 Figs 45 View Figure 45 , 46 View Figure 46 , 47 View Figure 47

Type locality.

Iran, Chaharmahal and Bakhtiari Province, Dimeh village, Chehme-Dimeh River, 32°30'11.62"N, 50°13'04.45"E; 2220 m a.s.l.

Distribution.

South-western Iran. Known only from few sites in the central Zagros (Fig. 45 View Figure 45 ).

Habitat.

Larvae inhabit streams and rivers at high altitude, 1721-2402 m a.s.l. (Fig. 45 View Figure 45 ).

Main morphological diagnostics of larvae.

(i) abdominal sterna II-VI with a pair of anteriorly widened oblique stripes (Fig. 46B, I View Figure 46 , arrows); (ii) abdominal terga V-VII with triangular, stripe-like or crown-like medial macula (Fig. 46G, H View Figure 46 ), often with lateral stripes extended dorso-posteriorly (Fig. 46H View Figure 46 , arrows); (iii) tergum X with postero-lateral projections (Fig. 47L, M View Figure 47 , arrows); (iv) femora with medial hypodermal spot (Fig. 46F View Figure 46 ); (v) setae on abdominal terga hair-like (Fig. 47E View Figure 47 ); (vi) gill plates III with well-developed projection (Fig. 47G View Figure 47 ); (vii) gill plates VII (in natural position from ventral view) relatively wide (Figs 46J, K View Figure 46 , 47H-K View Figure 47 ).

Remarks.

Taxonomy.

This species was described based on larvae collected from Zagros Mts. ( Hrivniak et al. 2020a). Imagines not described. The type series is currently deposited in SMNS, IECA, and MMTT_DOE. The lineage Caucasiron sp. 2 detected by Hrivniak et al. (2020b) is distributed in Turkey (Taurus Mts.) and morphologically corresponds to E. (C.) zagrosicus . Therefore, E. (C.) zagrosicus may represent a species complex.
