Description.

Adult. Male (Figure 23). Wingspan 12-13 mm. Segment 2 of labial palpus with scale brush almost as long as segment 3, brown on outer surface, whitish brown on inner surface, otherwise white; segment 3 about same length as segment 2, white, darker on lower surface and towards tip. Antennal scape with pecten of one hair; flagellum black, indistinctly ringed with grey. Head, thorax and tegula whitish grey-brown. Forewing light greyish brown from brownish white and black-tipped scales; base of costa blackish brown, otherwise whitish; fringes light grey. Hindwing grey with light grey fringes.

Female. Unknown.

Variation. The examined specimens show only slight variation.

Male genitalia (Figure 161). Uncus basally very broad, slightly longer than maximum basal width, gradually and weakly tapered from base to broadly rounded apex; gnathos hook slender, about one-third longer than uncus, weakly curved, narrowing towards pointed apex; anterior margin of tegumen with moderately deep and broad emargination, medial ridge from anterior edge to middle, anteriolateral edge with small peg-like sclerite; pedunculi distinct, irregular shape; valva moderately slender, long, maximum two-thirds width of uncus, gradually tapered to slightly pointed apex, extending slightly beyond middle of uncus; saccular area covered with numerous setae, without separated sacculus; posterior margin of vinculum with shallow medial emargination, lateral humps weakly developed, vincular sclerite sub-rectangular, with broadly sclerotised posteriomedial edges; saccus nearly V-shaped, apical third strongly narrowing, with pointed apex, ratio maximum width to length nearly 1, posterior margin arched, with small medial incision, medial part with short, furcated ridge from posterior edge almost extended to medial part, lateral sclerites about three-quarters length of maximum width of saccus; phallus moderately stout, with globular coecum, distal portion S-curved, with broad dorsal and long and slender ventral lobes, apically tapered.

Female genitalia. Unknown.

Diagnosis.

Megacraspedus junnilaineni sp. n. is characterised by its light greyish brown forewings without markings. Externally it is hardly separable from M. golestanicus sp. n. (p 48). The male genitalia are very similar to M. monolorellus (Figure 160) but differ in particular by the more slender uncus and gnathos hook, and the longer and comparatively slender valva. From other related species such as M. uzunsyrtus (Figure 162) and M. similellus sp. n. (Figs 163-164) they can be separated e.g., by the gradually tapered uncus.

Molecular data.

BIN BOLD:ADB7272 (n = 1). The distance to the nearest neighbour M. similellus sp. n. is 9.4% (p-dist).

Distribution.

Turkey.

Biology.

Host plant and early stages are unknown. The adults have been collected from the middle of May to the middle of August at altitudes of between 1200 and 1300 m.

Etymology.

The species name (a noun in the genitive case) is dedicated to Jari Junnilainen, Finland, who collected part of the type series of this species and numerous other valuable specimens used for our study.
