Description. Adult ( Figs 11–13 View FIGURES 11 – 18 ). Wingspan 19–21 mm. Segment 2 of labial palpus black, apically dirty white, especially on inner surface; segment 3 cream-white. Basal part of antenna brownish white, otherwise black. Head blackish grey, lighter at frons and around eye; thorax and tegula black, the latter with white base. Forewing black; costa from base to around middle of wing white with yellow outer margin; indistinct black spots in fold and at 2/ 3 in middle of wing followed by a few white scales; cilia black with dark grey tips. Hindwing grey.

Variation. Specimens from Turkey and Morocco are larger (wingspan 23–27 mm) and furthermore differ in having a larger part of segment 2 of the labial palpus whitish, the base of the antenna yellow-white and the head lighter grey.

Male genitalia ( Figs 52–61 View FIGURES 52 – 61 ). Valva broad, comparatively short, densely covered with long setae. Sacculus slender, comparatively long, covered with strong spines. Gnathos short, rounded. Uncus generally short, densely covered with long setae. Saccus short, subrectangular. Phallus slim, markedly curved, terminated by a short flagellum.

Female genitalia ( Figs 110 View FIGURES 108 – 113 , 121–128 View FIGURES 114 – 128 ). Subgenital plate narrowly sheath-shaped, without distinct excision. Ostium anteriorly extended. Ductus bursae long and thin, broader only in its basal part, with 7-10 convolutions. Ductus seminalis broader at base, membranous. Corpus bursae oval to nearly circular; signum elongated and covered by rather few stout spines.

Differential diagnosis. N. gregerseni sp. n. is externally very similar to N. lemniscellus . It differs in having segment 3 of the labial palpus whitish (yellowish in N. lemniscellus ), by having more whitish at the base of the antenna, a darker grey head, and by the presence of some whitish scales after the black spots in the forewing. In the male genitalia of N. gregerseni sp. n. sacculus is rather slender, valvae are shorter and broader and uncus is shorter and rounded compared with N. lemniscellus . The shape of the signum is the most striking difference in the female genitalia.

Distribution. With certainty known from North-east Europe. Records from the Ural Mountains, Altai Mountains and southern Sibiria ( Ponomarenko, 2008) may prove to refer to N. gregerseni sp. n. Specimens from Turkey and Morocco are tentatively also refered to this species.

Bionomics. Early stages and host plant unknown. Adults fly in late summer, in North Europe at low altitudes, and in Turkey in mountains at altitudes between 1400 and 2450 m.

Derivatio nominis. Named after the Danish lepidopterist Keld Gregersen, acknowledging his study of the north-west European Gelechiidae .

Remarks. Although the studied specimens from Turkey and Morocco are similar overall both externally and in the genitalia to specimens from NE Europe we have chosen to exclude them from the type series due to the small differences described above. Future studies of their DNA may reveal if they should be regarded as a distinct species.
