Remarks. Evergestis flavifuscalis was described by Rebel (1903) based on two females collected in Armenia (Yerevan: Korb) and preserved in the collection of Caradja, and one male specimen collected from Turkey (Taurus: Güllek) by Haberhauer in 1873 and deposited at the Naturhistorisches Museum Wien ( Rebel, 1903). However, it is unknown for the authors if the female genitalia has already been described. We found several females of this species with the same wing patterns stated by Rebel (1903) and those figured by Kemal & Koçak (2017). The female genitalia is here described and illustrated.

Diagnosis. Among the studied material some specimens had paler ground color with paler cross lines. The same was noted by Rebel (1903) when comparing the paler specimen collected from Turkey with those collected in Armenia with darker wing patterns.

As we revealed in this study, specimens with darker color pattern are almost similar to E. dusmeti externally, but differ in having wider sub-terminal gray band, more prominent and larger discal spot, which is also visible at the underside of forewings, and wide and dark terminal band of the upper surface of hindwings. The female genitalia of these two species are also similar, especially in having a very long dusctus bursae and small corpus bursae. Length of the forewing in female of E. flavifuscalis is x ̅ = 14.33 mm ± 0.41 (n= 7).

Description of the female genitalia. ( Figs 11A–E ) (n= 4). Papillae anales connected dorsally and distinctly setose; apophyses anteriores almost two times as long as the length of apophyses posteriores, with a pointed triangular process nearly at posterior one-third ( Fig. 11A ); antrum funnel-shaped, narrowed anteriorly and nearly short (extended to half length of the segment VII) ( Fig. 11A ); colliculum finely sclerotized and distinctly short (almost one-fifth of the length of antrum), normally positioned horizontally ( Fig. 11C ), but sometimes directed slightly upward ( Figs 11A, B ) and rarely positioned longitudinally ( Fig. 11E ); ductus bursae very long (almost six times as long as the length of corpus bursae), distinctly constricted and folded posteriorly near the junction with colliculum, with a clear right-angle bending at this area ( Figs 11A, B, C, E ), and broadened gradually towards the corpus bursae, with mostly distinguishable border between ductus and corpus bursae ( Figs 11A, D ); ductus seminalis arising at the bending of ductus bursae, its width at the arising point nearly as wide as the constricted end of colliculum ( Figs 11A–C ); corpus bursae small and spherical to ovoid, with a finely granulated surface and a pair of small longitudinal signa, length of signum almost one-fifth of the longitudinal length of corpus bursae or slightly more, with numerous triangular sclerites surrounded by tiny needle-like sclerotized structures ( Fig. 11D ); sternite VIII relatively narrow, its length in the longest area nearly 0.3 times the length of sternite VII or less.

Distribution. Turkey, Armenia ( Rebel 1903; Kemal & Koçak 2017).
