D e s c r i p t i o n. Adult ( FIg. 1 ). Wingspan 14.5–18.2 mm. Labial palpus rather short, straight, upper surface dirty-white, greyish-brown laterally. Distal brush of segment 2 well developed. Segment 3 about 1.2 times as long as segment 2. Scape dirty-white, with erected dense brush of long hairy yellowish scales anteriorly. Flagellum dirty-white with indistinct dark rings. Head dirty-white, tegulae covered frontally mainly with yellowish brown scales, caudally — with dirty-white scales. Thorax dirty-white with broad yellowish brown median longitudinal stripe. Forewing pattern is typical for the genus, yellowish brown, with brown wedge-shaped spot and with four silky-white longitudinal stripes. Сostal strip wide, tightly pressed to the anterior margin of the forewing, does not reach its root, projecting from 1/5 length to the apex of the costal margin. Medial stripe narrow, rather long, from 2/3 length to the tip of cilia; anal stripe broadest in middle, projecting from the root of the wing to about 2/3 length of the dorsal margin; dorsal stripe very long, projecting from the base of the forewing to about 1/2 length of the dorsal margin. Cilia of forewing greyish brown, with a large white patch in front of the medial strip. Hindwing light grey with a greyish-brown cilia. Abdominal tergites with moderately narrow paired patches of spinules ( FIg. 4 ).

Male genitalia ( FIg. 2 ). Gnathos broad, sub-trapezoidal with rounded corners. Tegumen rather broad and long. Transtilla lobes not connected medially, narrow, band-shaped, slightly broadened apically. Saccus very broad and short, apex with rather large tooth. Base of valva very broad (more than twice broader than long). Costa of valva without elongated curved setae. Valva deeply divided, cucullus comparatively short and broad, club-shaped. Sacculus strongly sclerotized, narrow and very long, reaching to about top of cucullus. Phallotheca rods short and very broad, strongly fused with each other except for membranous lower surface in distal half. The left rod narrow, apically pointed more than 5 times shorter and considerably narrower than the right rod. Cornutus very long and curved, consists of several FIlaments, twice longer as the length of the phallotheca.

Female genitalia (fig. 3). Ovipositor relatively long. Papillae analis medium in size, slightly narrowed and rounded apically, mostly membranous, densely covered with long setae, base with a distinct area of broad-banded sclerotization with an uneven, more or less serrated posterior margin. Both pair of apophyses relatively long and thin, apophyses posteriores more than twice as long and much more thinner than the apophyses anteriores. Sternum VIII relatively broad and short, its lateral parts rhomboid, the posterior lobes prolonged, bearing several thick long bristles. Ostium wide, cup-shaped, opens in the center of the sternum VIII. Antrum funnel- shaped, sharply narrowed towards the ductus bursae. The ductus bursa of moderate length and width, sclerotized in the caudal part, with a rather long spiny patch with a central bent that is nearly as long as a length of the spiny patch and extends far beyond its top. Bursa copulatrix medium in size, membranous, egg-shaped. Signum large, basal plate stout, terminal process long, broad on base.

Bionomics. M. jukkai sp. n. is most likely an univoltine species with adult flying during the early-summer phenological period (mid-May to mid-June). The new species was collected at light in mixed fescue-feather-grass steppe in SE Ukraine ( FIg. 5 ) and in steep river canyon with rocky slopes on both sides in SE Kazakhstan ( FIg. 6 ). Host plant and other aspects of bionomy are unknown.

C a s e o f m a t u r e l a r v a. Unknown.

D i s t r i b u t i o n. The species is known from Charyn valley (south-eastern Kazakhstan) and “Kamyani Mohyly” Nature Reserve (south-eastern Ukraine, Donetsk and Zaporizhzhya Regions).

Diagnosis. According to classiFIcation by S. J. Reznik (1977), the new species belongs to the fuscociliella (medicaginis)-section of the Multicoloria -genus and is closely related to Multicoloria fuscociliella (Zeller, 1849) . Externally, a new species well differs from M. fuscociliella in the larger size and lighter coloration of both pairs of wings. In the male genitalia M. jukkai sp. n., unlike M. fuscociliella , has wider gnathos, the shorter cucullus, and, especially, much more longer terminal process of sacculus and considerably longer cornutus.The female genitalia M. jukkai sp. n. differ from those of M. fuscociliella in the papillae analis more rounded apically, the thinner and longer apophyses posteriores, the much wider cup-shaped ostium, the presence a well sclerotized funnel-shaped antrum, the considerably longer spiny plot and central bent of the ductus bursa, and in much larger signum.

Etymology. The new species is named in the honor of Mr. Jukka Tabell (Hartola, Finland), one of the leading specialists for the family Coleophoridae in the World.
