Diagnosis. Elachista flavescens is a unicolorous white or pale yellow species. It is distinguished by the strongly serrate antennae which separate it from all other species of E. dispilella complex, except E. implana . The differences between these two species are presented in the diagnosis of E. implana . The cornutus group is similar to that of E. dispilella , the latter of which has simple antennae and broader valvae than E. flavescens . The female genitalia are characterized by the dilated posterior part of ductus bursae, with the colliculum represented by a strongly sclerotized band.
Molecular characterization. The analyzed 5 specimens of E. flavescens showed a maximum variability of 0.63 %. Average distance between the specimens was 0.25 %. The genetically closest species was E. ripai with 6.54 % minimum distance to E. flavescens .
Redescription. Wingspan 9–11 mm. Labial palpus creamy white, length 1.2 times diameter of head, scales of second segment distally long and somewhat raised. Head, neck tuft, thorax, scape and pedicel of antenna white or creamy white; flagellum dark grey, distinctly serrate. Foreleg inwardly leaden grey, legs otherwise ochreous white.
Forewing ground colour varying from nearly white to pale yellow with concolorous fringe, base of costa narrowly black; sometimes costal and/or tornal spot faintly visible, brown. Hindwing creamy white with concolorous fringe. Underside of forewing dark grey with creamy white fringe, underside of hindwing grey in anterior half, nearly white in posterior half, fringe pale grey along anterior margin, white along posterior margin.
Male genitalia. Uncus lobes twice as long as wide, sickle-shaped, somewhat distally tapered, mesial margin convex, apex acute. Spinose knob of gnathos oval-shaped. Valva 3/4 as long as tegumen + uncus, 4.5 times as long as broad, bent as s-shaped, parallel-sided; sacculus dilated; cucullus elongate, somewhat bent towards costa. Digitate process tongue-shaped, 0.2 times as long as valva, medially and distally with stout setae. Juxta lobes devoid of setae, mesial margin straight, joining the straight distal margin in a right angle. Phallus 1.1 times as long as valva, bent, parallel-sided; cornutus cluster prominent, formed of about ten spines set comb-like, basal spines slightly shorter than distal ones that are as long as diameter of phallus.
Female genitalia. Unknown.
Biology. Unknown.
Distribution. Armenia ( Parenti 1981), Russia, Turkey.
Remarks. The apparent length of the cornuti is dependent on the position of the vesica in the phallus.
