Derivatio nominis: The name refers to the black dot on the forewing.

Diagnosis ( Figs 15-16 ): Wingspan 14-18 mm; head brush white, scape, with pecten, and pedicellus of antennae white, flagellum light brown, with ciliae (0.5 of diameter of segments); labial palpi curved upwards, light brown, with some white scales; thorax and tegulae white, apically light brown; forewings bicoloured. Basal third brown, other part white, border between these parts straight from costa to dorsum; at 3/4, in the white area, at the end of cell a black dot; apex and fringe brown, hindwings shiny whitish.

Male genitalia ( Figs 52-55 ): Uncus apically incised, the two short lobi apically rounded; gnathos arms slightly curved, basal edge of tegumen more strongly sclerotised, vinculum with long saccus, proximal edge elongate, nearly triangular; valvae with straight costal edge, ventral edge from apodeme oblique broadened to strongly sclerotised angle at 1/2, from it to rounded apex narrower; inside, parallel to oblique ventral edge some strongly sclerotised wrinkles; subapically, below costal edge a short lobe. Shape of wrinkles and lobe varies (see fig. 55); phallus nearly as long as uncus-tegumen-saccus, basally rounded, slender, apically covered with numerous minute sclerotised thorns.

Female genitalia ( Fig. 56 ): Anterior apophysae unforked, ostium and first part of ductus bursae slightly more strongly sclerotised, area between the apophysae and ostium longitudinally with fine sclerotisations.

Remarks: The black dot makes the new species superficially distinguishable from the other members of the genus.
