Diagnosis. Hypsotropa unipunctella  is characterized externally by an ochreous to light brown forewing with dark veins especially near the costal margin. Hypsotropa limbella  is similar superficially but it is distinguished by a dark brown outer margin of the forewing ( Figs 7, 8View FIGURES 7–10). The comparatively narrow valva with a broadly triangular distal projection on its ventral margin in combination with a strongly serrated plate in the vesica are characteristic for the male genitalia. Hypsotropa limbella  has a broader valva with the distal projection more pointed and near the dorsal rather than ventral margin ( Fig. 10View FIGURES 7–10). Additionally, the aedeagus of H. limbella  bears a very small plate with three little cornuti in the vesica ( Fig. 10View FIGURES 7–10). The female genitalia are characterized by a ductus bursae covered with fine spinules in its anterior portion, in combination with a colliculum about 1/3 length of the ductus bursae. The female genitalia of H. limbella  is very similar but the ductus bursae has no spinules, the colliculum is longer and less sclerotized ( Fig. 9View FIGURES 7–10).

Re-description. Adult ( Figs 1–3View FIGURES 1–6). Wingspan 16–21 mm.

Head yellow to light brown; frons with triangular tuft of scales; labial palpus light brown, narrow, inner surface white, about three times as long as diameter of an eye, upcurved, segment 3 about 1/4–1/5 length of the segment 2, pointed; scape and flagellum yellow, ringed with brown; antenna in male thicker than in female; proboscis reduced to about half length of the labial palpus.

Thorax and tegulae yellow to light brown. Forewing light brown, veins mottled with light brown or black, subcostal area white, indistinct black point in fold and in cell, cilia light brown; hindwing and cilia light grey.

Variation. Specimens may appear lighter or darker depending on development of brown irrorarition along veins.

Male genitalia ( Figs 4a, bView FIGURES 1–6). Uncus lobes long, slender pointed apically. Gnathos arms slender, distal process narrow, elongated, pointed. Tegumen weakly sclerotized, subrectangular. Valva elongated, moderately broad in basal 2/3, then distinctly narrowing towards pointed apex; densely covered with long hair-like setae along ventral margin and in distal 1/3, both margins strongly edged to 2/3 length; basal process a long slender spike, pointed; a broadly triangular process from near 2/3 of ventral margin. Juxta plate-shaped, broader than long, subovate. Saccus stout, horseshoe-shaped. Aedeagus about 2/3 length of valva, basal half weakly narrowed on one side, distal half nearly parallel-sided; vesica with a cluster of one long, three short and a few minor cornuti.

Variation. Two males examined from Ukraine show no variation.A male from Zabaikalskiy kray, Russia, differs in narrower lobes of its uncus, an apically broader valva and a large number of smaller cornuti in its vesica ( Figs 5a, bView FIGURES 1–6).

Female genitalia ( Fig. 6View FIGURES 1–6). Papillae anales narrow, subtriangular, densely covered with long setae. Apophyses anteriores as long as apophyses posteriores. Segment VIII slightly longer than broad, evenly sclerotized, posterior margin weakly excavated, anterior margin rounded; subgenital plates subtriangular, joining in middle length of sternum VIII. Ductus bursae as long as apophyses, moderately broad, densely covered with minute spinules beyond entrance of corpus bursae; colliculum distinct, about 1/3 length of ductus bursae. Corpus bursae as long as ductus bursae, ovate, without signum.

Biology. Host plant unknown. In Ukraine, adults have been collected from mid June to mid September.

Distribution. South and Central Europe; Russia: Tuva, Zabaikalskiy kray, Amurskaya oblast; China ( Sinev 2008; Leraut 2014). Ukraine: Zakarpattia ( Andrianov 2018), Kyiv (new record), Zaporizhzhia ( Bidzilya et al. 2013), Dnipropetrovsk (new record), Kharkiv (Karolinsky et al. 2018), Luhansk (new record) regions and Crimea ( Bidzilya & Budashkin 2004 as limbella  ; Budashkin 2004, 2006 as limbella  ; Savchuk & Kajgorodova 2015).
