Description. Adult ( Figs 14–18 View FIGURES 11 – 18 ). Wingspan 16–23 mm. Segment 2 of labial palpus black at base, apically white, especially on inner surface; segment 3 cream-white. Scape of antenna black; flagellum light yellow-brown, indistinctly darker ringed. Head cream-white, darker in middle; thorax and tegula as forewing. Forewing light yellow-brown with black spots at base, in fold and at ½ and 2/ 3 in middle of wing: scattered black scales along veins, especially in apical part; black spots along termen; cilia grey with dark grey cilia line. Hindwing grey.

Variation. A moderately variable species. The colour of the forewing varies from light yellow to brown, and the amount of black scales in the forewing varies from few to numerous. In some specimens the black spot at 2/3 is very prominent. Specimens from the south-eastern part of the distribution area have generally lighter yellow forewings (see also Remarks). Specimens bred from larvae are sometimes clearly smaller that specimens collected as adults.

Male genitalia ( Figs 62–69 View FIGURES 62 – 75 ). Valva very narrow, slightly broadening apically, with an indistinct conchoidal bulge at base and covered with setae in its distal part. Uncus broad, bluntly terminated, slightly tapering apically. Gnathos narrow, arcuate, strongly sclerotized in its last third. Sacculus narrow, long, markedly bent in middle, tapering apically, from the bend to the apex covered with strong sclerotized spines. Saccus thumb-like. Phallus comparatively short, terminated by a filiform flagellum forming one loop. Coecum bulbous.

Female genitalia ( Figs 111 View FIGURES 108 – 113 , 129–130 View FIGURES 129 – 136 ). Papillae anales thin, elongated. Apophyses posteriores comparatively long, approximately two times as long as apophyses anteriores. Subgenital plate very narrow, slightly more narrow distally. Ductus bursae comparatively short and broad in its whole length, membranous, distally straight, proximally approximately four times coiled. Ductus seminalis broad and membranous at first, then tapered and forming a loop, spined. Corpus bursae oval, elongated, signum conspicuous, basal plate broad, elongated, terminally rounded with two large lateral plates which together form a circle.

Differential diagnosis. N. verbascella is characterized by its yellowish or light brownish forewings with three black dots and scattered black scales. It may be confused with the somewhat lighter N. skyvai (for differences see under this species). See also N. congressariella .

In the male genitalia an easily distinguishable species with respect to the very narrow and markedly curved sacculus, short gnathos and a thumb-like saccus. Females are easily distinguishable with respect to the long and narrow papillae anales, narrow subgenital plate and characteristic shape of signum.

Distribution. Europe, northwards to central Scandinavia, European Russia, North Africa, Middle East, Turkey. Also recorded from Iran (e.g. Zerny 1939), Iraq ( Amsel 1949) and Turkmenistan ( Christoph 1885).

Bionomics. The larva is described by e.g. Emmet & Heckford (2002: 222). It lives gregariously among spun leaves and within shoots of Verbascum L. species, pupating underneath the lowest dead leaves. It has been reported as a pest on cultivated Verbascum phlomoides L. ( Łęgosz-Owsianna 1954).

Remarks. Tinea verbascella was described from an unstated number of specimens from the Vienna area ( Austria), bred from Verbascum thapsus (“Verbasci Tapsi”). Koçak (1984) has argued that the description is unavailable, but his argument has not been generally accepted, and stability of nomenclature is best served by accepting the description of this and other species in Denis & Schiffermüller’s work as valid ( Sattler & Tremewan, 1984).

Nothris discretella was described from a single male collected near Graz in south-eastern Austria. Due to its dark brownish grey forewings, Rebel (1889) compared it with N. congressariella , but its genitalia show it to be a synonym of N. verbascella .

Nothris verbascella clarella was described from an unstated number of specimens from Israel (Karmel) and Palestine (Jericho). Amsel (1935) stated the subspecies clarella to be about 3 mm smaller than nominotypical N. verbascella , much lighter and with smaller and fewer black scales in the forewing. We examined a paratype which, apart from being lighter, does not differ from specimens from other parts of the distribution area. Also the (male) genitalia are very similar, with only the apex of sacculus being narrower and more distinctly tapering into the tip. Although specimens from the eastern Mediterranean area generally are paler (especially the hindwings) N. verbascella is a variable species, and we do not find specimens from that area sufficiently distinct to deserve status as a subspecies.

Vives Moreno (2015) listed Recurvaria lutarea (Haworth, 1828) as a synonym of N. verbascella . Here we follow the opinion of Beccaloni et al. (2005) and treat it as a synonym of Pexicopia malvella ( Hübner, 1796) .
