Holotype: ♂, Russia: Crimea, vicinity of Ordzhonikidze, Dvuyakornaya Bay, 44º58'48"N, 35º22'12"E, saline area, 10. V 2006, coll. Yu. Budashkin (gen slide 76/18, O. Bidzilya) (ZIN). Paratype: ♂, Kazakhstan: Ketmen Mts, Rahat Kuduk, 43º37'52"N, 79º55'50"E, h= 650 m, 2. VI 2014, coll. K. Nupponen & R. Haverinen (gen slide GP 7358 J. Tabell) (KN). DESCRIPTION. Imago. Wingspan 7.9 mm (Fig. 9). Labial palpus short and thick, nealy straight, weakly up-curved, light grey on upper surface, grey mixed brown laterally. Segment 2 without terminal brush, sub-equal in length with segment 3. Scape light grey, covered with smooth scales including the anterior side. Flagellum dirty-white with well developed dark grey rings. Head light grey. Tegulae light grey. Forewing light grey with grey areas in the proximal part of the wing and with numerous dark grey scales. Cilia grey with numerous dirty-white separate scales. Hindwing grey. Cilia grey with separate dirty-white scales. Spinous plates on abdominal tergites relatively narrow (Fig. 13). Male genitalia (Figs 10–12). Gnathos rounded. Tegumen short, broadly triangular at base, constricted medially. Transtilla branches medially connected, broadened in middle, band-shaped. Valva relatively narrow, cucullus short and narrow, rounded apically. Sacculus short, well sclerotized, in the form of short distally narrowed, but not pointed lobe with small rounded outgrowth in the middle at the base of its tapering part. Pfallotheca rods moderately short, narrow, fused all over. Apex of phallotheca with a rather long downward curved more or less coracoid process. Rather thick and long, straight spine-shaped apically rounded process on the mid length of the phallotheca on its left side. Cornutus in form of the rather tick spike of medium length on relatively large basal plate. Female unknown. DIAGNOSIS. New species belongs to decoratella species group of the genus Casignetella, which also includes four other species: C. decoratella (Toll, 1959), comb. n. (Iran), C. afrosarda (Baldizzone et Kaltenbach, 1983), comb. n. (Spain, France, Sardinia, North Africa), C. kalidii (Falkovitsh, 1989), comb. n. (Turkmenistan) and C. immersa (Falkovitsh, 1989), comb. n. (Turkmenistan). New species differs from C. decoratella by the considerably smaller size and from other species of this group by the structure of the male genitalia. Unlike C. afrosarda, C. kalidii and C. immersa in the male genitalia of the new species the phallotheca rods fused all over and have completely different weapon of spike and tooth-like outgrowth. The new species has the narrowest among all three related species sacculus. In addition the new species differs from C. afrosarda and from C. kalidii by much more shorter cornutus. BIONOMY. Holotype was collected by netting over the vegetation in the evening in the saline marshes. DISTRIBUTION. South-Eastern Crimea, South-Eastern Kazakhstan. ETYMOLOGY. The new species is named in the honor of Kari Nupponen, wich collected this species in South-Eastern Kazakhstan.
