We obtained two identical sequences from the specimens with CaBOL-IDs 1038589, 1038590 (BOLD:ADM7968), with the best match in BOLD Systems being unidentified Zeuzerinae from David Gareji (Georgia) (BOLD:ADM7968, p -distance 0.16%), presumably belonging to the herein described species. The second-best match was unidentified Phragmataecia from Taiwan (BOLD:AAY5999, p -distance 5.78%). Diagnosis. By the conformation of genitalia, the males of the new species are closest to P. valikhanovi Yakovlev & Witt, 2016 from Kazakhstan, from which they differ by the absence of black scales on the ventral side of both the forewings and hindwings and overall darker coloration on the dorsal side and sharper apex of valvae and stronger curve of aedeagus. (Figs 24, 39–42; cf. Yakovlev & Witt 2016: figs. 1–4, figs 10–11). From those of occurring in the Caucasus congeners as follows: from P. castaneae by the absence of wing pattern, presence of longitudinal series of tiny dark points between veins medially, shorter uncus, and sharper saccus (Figs 24, 39, 40; cf. Yakovlev & Snegovaya 2020: fig. 2b); from P. effendi Yakovlev & Snegovaya, 2020, by sharper apex, thinner valvae, and differently shaped aedeagus (Figs 39–42; cf. Yakovlev & Snegovaya 2020: fig. 2a); from P. pacifica Yakovlev, 2007, by relatively straight aedeagus and straighter posterior margin of valvae (Figs 39–42; cf. Yakovlev 2007a: figs 9; Yakovlev & Witt, 2016: fig. 9); from newly described P. durska Saldaitis, Yakovlev & Prozorov, 2025 by straighter aedeagus and narrower valvae (Figs 39–42; cf. Saldaitis et al. 2025: figs 18–19). Description. Male (Fig. 24). Wingspan 40 mm. Antennae 1/3 of the length of the forewing; rami gradually elongate in basal third of antennae, rapidly shorten in distal half of medial thirds of antennae, and barely pronounced until the tip; flagellum and rami covered with white-brounish scales. Head, thorax, and abdomen densely hirsute, brown-greish. Forewing 17.5 mm; narrow, long, with protruded obtuse anal and tornal angles, rounded apex; brown-greish coloured with sparse blackish scales. Hindwing triangular; rounded anal angle and apex; light brow-whitish colour, lighter in the basal costal area. Genitalia as in Figs 39–42. Uncus triangular with lateral concavities; apex blunt, beak-shaped, sclerotised. Tegumen narrow, concave. Vinculum narrow, ventrally expands into triangular saccus with round apex. Valva dorsally straight, concave near sacculus; apex sharp. Aedeagus slightly longer than valvae slightly curved in medium third. Female unknown. Pupae (Fig. 53). Length 20 mm, width 4 mm; brown. Variation. Males (n=6). Wingspan 38–52 mm. Forewing 17–24 mm. Etymology. From Latin “ ignotus ” meaning “unnoticed”, alluding to the species being previously overlooked. Habitat. All specimens were collected along riverbanks abundant with Phragmites australis (Cav.) Trin. ex Steud. (Fig. 49). Distribution. Above-mentioned localities only (Fig. 43). Remarks. During the May 2025 expedition to the species’ type locality, numerous Phragmites stems were collected, yielding a single pupa, found near the base of the stem (Fig. 53). It was notably active, moving up and down using abdominal contractions. The eggs and larval stages of this species remain unknown.
