Cerostoma kotzschi Toll, 1947: 165. Type locality: NE Iran, Kuh-i-Mirabi Mts., 2000 m.
Type. Holotype: ♂, labelled: “ Typus ” [printed red rectangular label]; “Hyrcania, Kuh i Mirabi mont, 2000 m. VII.-VIII.” [printed]; “Praeparat No. 1299.” [hand-written]; “ Cerostoma Kotzschi Toll. ” [hand-written], deposited in the Institute of Systematics and Evolution of Animals, Polish Academy of Sciences (Krakow, Poland).
Diagnosis. The external appearance clearly distinguishes this species from Y. vittella. The colour and patterns of the forewings are different from those of other known similar species: Y. colleaguella Baraniak, 2007 and Y. strigosus (Butler, 1879) (Baraniak 2007; Moriuti 1977). The male genitalia of Y. kotzschi are close to those of Y. vittella. The valva is similar in shape, but the aedeagus of the former species is tiny, 1.5 - times longer than valva, with only one long cornutus in the vesica. Additionally, in Y. kotzschi the saccus is short, only 1/3 of valva length and only slightly wider than valva. The gnathos shape of Y. kotzschi is similar to that of Y. vittella, but in the latter species the microscopic teeth are tiny and thin.
Redescription. Wingspan 22.5 mm. Labial palpus three - segmented, middle segment longest; first segment and base of second segment white; third and remainder of second segment with extensive admixture of yellow scales and individually scattered dark fuscous scales; scale tuft of middle segment clearly exceeding segment in length, similarly tinged. Maxillary palpus white. Antenna with scape and first flagellomere white (only five flagellomeres of left antenna preserved, while right one missing), remaining flagellomeres white with pale brown rings. Forewing elongate, with a pointed apex, clearly bicoloured; white, with yellow sprinkling on veins along costal margin and on basal 3/4; just before apex densely mottled with yellow scales; straw yellow with darker sprinkling of scales on veins along dorsal margin; a narrow stripe formed by dark yellow scales from the base of the forewing to the middle of its length; apex light yellow. Hindwing and fringe yellow. Thorax white. Abdomen yellow.
Male genitalia: Socii slender, densely setose, pointed apically. Tuba analis membranous. Uncus small. Valva oval, sacculus not defined. Saccus elongate, 1.3 times shorter than valva, rounded at the distal end. Gnathos long, forming a spoon-like ventral plate with tiny, broader at the base and slightly sharpened teeth. Aedeagus, slender, 1.5 times longer than valva, with apically pointed cornutus. Anellus short, with small denticles.
