description: Genus Sabaha M. Omelko et N. Omelko, 2019
Type species: Sabaha spathulata M. Omelko et N. Omelko, 2019.
DIAGNOSIS. Adult (Figs 1, 2, 11–23). Wing length 5.0–8.2 mm. Scapus with prominent elongated scales along anterior or posterior margin, or along both edges; pedicellus and basal flagellomeres widened, if strongly widened, this part looks like an oblong or rounded lobe with elongated scales along the edges; flagellum of male with short or long cilia below, sometimes appears serrate due to tufts of raised scales (Fig. 8). Forewings with tufts of raised scales or covered with hair-like raised scales, giving them a velvety appearance. Hindwings with semi-transparent area between radial and cubital veins, covered with short hair-like scales (Fig. 4), the colour of this area changes to greenish, blue, purple, reddish or golden due to the refraction of light. Forewing with Sc to costa at about middle of wing length; R 1 – R 5 to costa, R 1 and R 2 separate at the base, R 3 and R 4+5 connate basally, R 4+5 stalked, diverging before middle; M 1 and M 2 separate basally, to termen, M 3 and CuA 1 shortly stalked basally, CuA 2 separate basally, to termen; CuP present at basal part only, 1A and 2A merged distally. Hindwing with Sc + R 1 to costa beyond 2/3 of wing length, Rs to costa before apex, Rs and M 1 stalked, M 2 separate, to termen, M 3 and CuA 1 stalked, CuA 2 separate, to dorsal margin (Fig. 10).
The moths of both sexes possess the bundles of long hair-like scales with a common cupshaped or convex base, each is located on the lateral part of the metascutum posterad the hindwing (Figs 5–7, 9). Abdominal 2nd sternite with arched venulae and slightly curved medially apodemes (Fig. 43).
Male genitalia (Figs 24, 25, 27–42). Uncus relatively small, hood-shaped. Gnathos with well-developed culcitula divided by a longitudinal median constriction into two portions, and with small and flat median sclerite of different shape; besides two long flat sclerites curved medially articulated to lateral arms anterad gnathos. These sclerites of unknown homology called “fultura superior” in species from the genus Gelechia Hbn. Valva completely divided into cucullus and sacculus. Cucullus with more or less long neck, its distal setaceous part moderately dilated. Sacculus lamellar, oblong, with a claw-like apex curved ventrally, integrated with vinculum and juxta. Aedeagus tubular, arcuately curved, rarely almost straight, distally lobate, with apex of various shape, basally with apodemes and without caecum; fixed in the proximal part by a semi-sclerotized anellus. Vinculum with wide lateral parts and ventral excision, saccus wide, triangular or trapezoid.
Female genitalia (Figs 26, 44–48, 50–59). Papillae anales oblong and relatively small. Ovipositor very long, apophyses posteriores 7–12 times as longer as apophyses anteriores. 8th segment of abdomen strongly elongated, with narrow membranous gap ventrally, often sclerotized and bearing setae on posterior edge laterally. Ostium and anterior part of 8th sternite, covered by more or less semi-sclerotized two-layer fold fused with base of apophyses anteriores anteriorly. This fold forms vaginal sinus and with honeycomb-like sculpture on inner surface, more often as two elongated area (Figs 26, 45, 50, 53, 56, 58). Vaginal part of ductus bursae widened, membranous or slightly sclerotized; ductus bursae membranous, smoothly delated towards corpus bursae; the latter relatively small, membranous; signum more or less rhomboid plate with transverse gutter. Ductus seminalis arises beyond vaginal part of ductus bursae and forms saccular bulla often with small spines on inner side.
