Type material. Holotype ♂: Italy: Teriolis mer. Naturns p. Meran, 20.–30.VI.1935, J. Klimesch leg., 6, 24, L. Kaila prep. 5909 ( ZSM). Paratype ♂: the same collecting data except 30.VI.–5.VII.1935, L. Kaila prep. 5910 ( ZSM).

Diagnosis. Elachista implana is a close relative of E. flavescens , both species having strongly serrate antennae that distinguish them from other species in the E. dispilella complex. These species can be separated from each other as follows: spinose knob of the gnathos is oval-shaped in E. flavescens , rounded in E. implana ; the valva is straight, slightly broader and longer in E. implana than in E. flavescens as related to the length of uncus + tegumen; the cornutus group is composed of regularly arranged row of slender spines in E. flavescens , that of E. implana is irregular with respect of both size and arrangement of spines that are stouter than in E. flavescens . The female is unknown.

Molecular characterization. No material was available for genetic study.

Description. Wingspan 9.5– 10 mm. Labial palpus creamy white length 1.2 times diameter of head, scales of second segment somewhat raised. Head, neck tuft, thorax, scape and pedicel of antenna white or creamy white; flagellum dark grey, distinctly serrate. Legs grey, hindleg pale ochreous, except spurs and tarsal articles grey. Forewing ground colour varying from nearly white to pale yellow with concolorous fringe, basal 2/3 of costa grey. Hindwing grey with concolorous fringe. Underside of forewing dark grey, fringe scales basally ochreous, distally white, underside of hindwing grey in costal half, nearly white in dorsal half, fringe pale grey along anterior margin, white along posterior margin.

Male genitalia. Uncus lobes twice as long as wide, sickle-shaped, distally tapered, mesial margin convex, apex acute. Spinose knob of gnathos rounded. Valva 3/5 as long as tegumen + uncus, 4.8 times as long as broad, straight, parallel-sided; 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 formed of about ten closely set stout spines, with short and long spines intermixed.

Female. Unknown.

Biology. Unknown.

Distribution. Italy.

Remarks. During the dissection of the male genitalia of E. implana somewhat less pressure has been applied during mounting as compared to E. flavescens . Therefore the width of valva in the images of E. implana appears narrower than it actually is, and the width difference to E. flavescens is in reality more pronounced.
