Aristotelia confusella View in CoL sp. n.

Aristotelia staticella sensu Bidzilya & Budashkin, 1998: 10 View in CoL . Aristotelia brizella sensu Bidzilya & Budashkin, 2009: 16 View in CoL .

Material. Holotype ♂, Crimea, Yuzhnoye Prisivashje, okr. Lvovo, 17.v.2013 (Budashkin) ( ZMKU). Paratypes: 1 ♂, same data as holotype but 23.v.2013 (gen. slide 201/14, O. Bidzilya); 1 ♂, same data but 26.v.2013; 1 ♀, Crimea, Evpatoria, 23.viii.2005 (Puzanov) (gen. slide 59/07, O. Bidzilya); 1 ♀, Ukraine, Zaporozhie vic., Gadjuchia balka, 19.v.1991 (Zhakov); 1 ♂, 1 ♀, Ukraine, [Donetsk reg.] Khomutovskaya step, 18, 23.v.2006 (Bidzilya) (gen. slide 46/ 13♂, O. Bidzilya) (all ZMKU).

Comparative material studied. Aristotelia staticella : 1 ♂, 1 ♀, Cannes, S France, 1887, Constant, Wlsm. Coll. (gen. slide 34180♂; 34181♀, O. Bidzilya) (NHM); 1 ♂, Cannes, Const. (gen. slide 358/14, O. Bidzilya); 1 ♀, Gallia mer. (gen. slide 359/14, O. Bidzilya) (all MFN).

Description. Adult ( Figs. 24, 25 View FIGURES 24 – 32 ). Head: White with brown medial longitudinal strip; labial palpus up-curved, segment 2 and segment 3 white with brown medial and subapical annulations, inner and upper surface of segment 2 white; scape brown with white top, other antennal segments brown with white basal rings.

Thorax: Dorsum and tegulae brown; wingspan 7.0–7.2 mm; forewing with brown costa with yellow spots beyond base, midwing, and outer third, interrupted with silver subapical strigulae, apical ¼ brown, some specimens with a striae of silver scales extending from between dark scales on costal margin, diffuse silver spot on costal margin just after mid-point, two brown dots on dorsal margin at 2/3 length and near middle; cilia grey, brown tipped; hindwing grey.

Abdomen: Male genitalia ( Figs. 28, 29 View FIGURES 24 – 32 ) with uncus about 2 times longer than broad, evenly narrowed towards rounded apex; gnathos longer than uncus, stout, pointed apically; tegumen subrectangular, anteromedial emargination broad, shallow; valva elongate, broadened in distal half, pointed apcially, inner margin straight, outer margin curved in distal half, not extending over top of uncus; sacculus narrow, less than 1/3–1/4 length of valva, curved inwards, inner margin weakly serrated; vinculum narrow, posterior margin slightly broadened in middle; saccus subrectangular, about 2.5 times longer than broad; phallus strongly swollen in base, distal portion narrow, apex rounded or weakly pointed. Female genitalia ( Fig. 31 View FIGURES 24 – 32 ) with papillae anales elongate, covered with short hairlike setae; apophyses posteriores straight, narrow, more than 2 times length of papillae anales; segment VIII subrectangular, about 1.5 times broader than long, tergite VIII evenly sclerotized, anterior margin of sternite VIII weakly protruded anteriorly, posterior margin with deep anchor-shaped medial emargination, subostial sclerite large, elongate, with medial fold, apical portion triangular, extending over posterior margin of sternite VIII; apophyses anteriores narrow, straight, as long as segment VIII; ductus bursae narrow, weakly broadened and coiled before corpus bursae, middle 1/3 covered with microtrichia, colliculum band-shaped, sclerotized laterally; corpus bursae weakly elongate; signum an ovoid, egg-shaped plate with strongly sclerotized and serrated margins.

Diagnosis. The new species is closest to A. brizella in DNA barcode with a divergence of 1.8% (P. Huemer, pers. comm.). It also is similar to A. brizella in the genitalia of both sexes but differs in having a valva that is narrower and weakly constricted in the basal 2/ 3 in the male. In the female genitalia the subostial sclerites are broadly separated in the new species, whereas they are connected in A. brizella . The two species also differ in forewing pattern: A. confusella lacks oblique silver marks on the costal margin, which are characteristic of A. brizella . A. staticella ( Figs. 26, 27, 30, 32 View FIGURES 24 – 32 ) also is related to A. confusella , sp. n. The differences between A. confusella and A. staticella are summarized in the Table 1 View TABLE 1 .

Biology. Adults were collected in May and in August during the day (early morning or before sunset) in salinesteppes biotopes dominated by Limonium meyeri (Boiss.) O. Kuntze (Limoniaceae) , which is a possible larval host plant.

Distribution. Ukraine: Donetsk region (Khomutovskaya Steppe Nature Reserve), Zaporozhie reg., Crimea. Etymology. New specific name is derived from the Latin confus – confused, in reference to our long confusion of this species with A. brizella .
