Diagnosis. Ancylosis larissae sp. nov. is relatively small species with light brown forewing, white costal margin and pink transverse fasciae. Ancylosis hellenica differs in the brighter, yellowish-brown forewing with distinct pink fasciae, of which subapical one is distinctly angulated ( Figs 24–28 ). Ancylosis rhodochrella is very similar but differs in the presence of distinct red irroration under costal margin, whereas white pattern is very narrow ( Fig. 22 ). The males of A. rhodochrella differ both from A. larisssae sp. nov. and A. hellenica in the longer cilia on antennae (½ width of the flagellum contrary to ⅓-½ in A. larisssae sp. nov. and A. hellenica ) ( Figs 29a, 30a, 31a ). The distinctly narrowed after ⅓ length valva with short rounded hump on ⅔ length of ventral margin in combination with long slender aedeagus are characteristic for the male genitalia of the new species. Ancylosis rhodochrella and A. hellenica differ in the absence of short broadly rounded hump on the ⅔ of the dorsal margin of the valva. The new species differs additionally from A. rhodochrella in the absence of lateral subapical hump on the top of the aedeagus. Ancylosis hellenica has an aedeagus more distinct broadened in middle and with oblique cut rather than truncate in A. larissae sp. nov., top. The female genitalia are recognizable by broad funnel-shaped antrum in combination with very short, slender ductus bursae and long pear-shaped, distally curved corpus bursae with numerous thorn-shaped signum. Ancylosis hellenica has ovate rather than pear-shaped corpus bursae with longer signa. Ancylosis larissae sp. nov. and A. hellenica can additionally be separated by the ductus seminalis. It is basally broadened and arises from the top of the ductus bursae in A. hellenica . In A. larissae sp. nov. the ductus seminalis is longer, narrower and arises from the first ⅓ of the ductus bursae.

Description. Adult ( Figs 24–28 , 30a, b). Wingspan 15.8–17.0 mm. Head off-white, mixed with light brown, labial palpus with several brown-tipped scales on outer surface, up-turned, weakly protruded over the head; antennae light brown, ciliated underside in male, cilia about ⅓ as long as a width of flagellomeres; thorax and tegulae light brown; ground colour of the forewing light brown, costal margin dirty-white sparsely mixed with light brown from base to about 4 / 5 length, broad pink basal oblique fascia on basal ¼, narrow pink fascia before middle, diffuse pink dorsally narrowed fascia on ⅔, apex distinctly mottled with pink, cilia light brown with darker divided line; hindwing dark grey, central part lighter, cilia light grey, brown in basal ⅓.

Variation. The pink fasciae are completely reduced in some specimens ( Figs 25–27 ).

Male genitalia ( Figs 49, 50 ). Uncus twice as long as broad at base, gradually narrowed towards rounded apex, scaphium folded, about ⅓ length of uncus; distal sclerite of gnathos narrow, weakly curved dorsally, extending to mid length of uncus; tegumen subtriangular, as long as broad at base, with distinct transition to uncus; valva parallel-sided in basal half, then ventral margin gradually narrowed towards rounded apex, with short rounded extension on ¾ length, costa weakly bend before apex, subcostal hump small, sacculus weakly sclerotized; juxta u-shaped, tips strongly sclerotized, rounded; transtilla lobes elongated, subtriangular; vinculum moderately broad, gradually narrowed towards weakly rounded apex; aedeagus slender, weakly constricted after half length, extends to the middle of uncus. Culcita slender, posterior margin broadly rounded, anterior margin straight.

Variation. Two studied males varying in the width of uncus and length of vinculum.

Female genitalia ( Fig. 69 ) Papillae anales subtriangular, densely covered with long hairs; apophysis anterioris straight, twice as long as the length of papillae anales; segment VIII twice as broad as long, tergum VIII evenly sclerotized, anterior margin nearly straight, sternum VIII with broad anteromedial emargination, posterior margin straight; ductus bursae short, slender, antrum broad, funnel-shaped, as long as the length of the ductus bursae, ductus seminalis narrow, arises from the first ⅓ of the ductus bursae; corpus bursae longer than combined length of papillae anales, segment VIII and ductus bursae, pear-shaped with curved posterior portion, numerous hook-shaped signa with rounded base in middle ⅔ of corpus bursae.

Biology. Host plant is unknown. Adults were registered from mid July to late August. Three specimens were attracted at light in Karadag Nature Reserve. Three additional specimens, two male and female, were collected during the evening netting and at light in the mountain-xerophytic habitats in Uzun-Syrt ( Fig. 78 ) and in the vicinity of Fruktove village near Sevastopol.

Distribution. Ukraine (Crimea).

Etymology. The species is named in honour of Streltsova Larisa Vadimovna, a charming women, a high scilled specialist and a very devoted friend of the second author.

Remarks. The female holotype of new species has completely reduced pink pattern ( Fig. 27 ). However, its genitalia are similar to the female paratype that has distinct pink transverse fasciae ( Fig. 24 ). Hence, we have no doubt in conspecificity of uniformly light brown specimens with specimens having distinct pink pattern. The photographs of A. rhodochrella from Uzun-Syrt ( Savchuk 2019) belongs to A. larissae sp. nov. The female illustrated in the right lower corner is included in the type-series.

Notes to related species: Ancylosis hellenica ( Figs 23 , 29a, b, 46–48, 70) was described based on two males and two females collected in Attica ( Greece). The lectotype is not designated. The female genitalia of syntype ( Fig. 70 ) differ considerably from the drawing by Roesler (1973: Pl. 135, fig. 183), who erroneously synonymized Staudingeria deliciosella Caradja, 1910 with A. hellenica and figured the female genitalia of the holotype of deliciosella under the name hellenica (Slamka, pers. com.). Below we describe the female genitalia of A. hellenica for the first time.

Female genitalia of A. hellenica ( Fig. 70 ). Papillae anales subtriangular, densely covered with long hairs; apophysis anterioris straight, twice as long as the length of papillae anales; segment VIII twice as broad as long, tergum VIII evenly sclerotized, sternum VIII with broad anteromedial emargination, posterior margin straight; ductus bursae short, slender, antrum broad, funnel-shaped, as long as the length of the ductus bursae, ductus seminalis weakly broadened at base, arises from the posterior end of corpus bursae; corpus bursae longer than equally combined length of papillae anales, segment VIII and ductus bursae, sub-ovate, with numerous long hook-shaped signa with rounded base.

Ancylosis hellenica is recognizable externally by yellowish-brown forewing with distinct narrow pink transverse fasciae the subapical of which is distinctly angulated ( Fig. 23 ). In male genitalia the valva of A. hellenica is nearly of equal width to about ¾ length, contrary to this of A. rhodochrella and A. larissae sp. nov. that is distinctly narrowed in its distal half ( Figs 46–48 ). The subovate corpus bursae covered with narrow comparatively long signa and basally broad ductus seminalis are characteristic for the female genitalia.

Ancylosis rhodochrella ( Figs 22 , 31a, 32b, 45, 71) was described based on single female from Amasia ( Turkey), but not from the male from Lambese ( Algeria) as it was stated by Roesler (1973: 424). The species is characterized externally by reddish-brown forewing with very narrow white costal pattern, two isolated dark-yellow irregular spots and dark yellow transverse subapical pattern separated from white costal margin by distinct red irrorration ( Fig. 22 ). The long cilia on the male antenna ( Fig. 31a ) is the additional character for the separating A. rhodochrella from A. hellenica and A. larissae sp. nov. The male genitalia differ from those of A. hellenica and A. larissae sp. nov. by the aedeagus having distinct triangular subapical hump ( Fig. 45 ).
