BB76B4A7871054829F0E253DFB129B03.taxon	diagnosis	Diagnosis. Monopis jussii sp. nov. is externally close to M. laevigella, but the forewing appears darker, as it is less mottled with pale scales, especially along the margins (Figures 4, 5). Fringes are yellow and with a clear fringe line in M. laevigella but grey and without the fringe line in M. jussii. Besides the genetic markers, the forewing colour is indeed the best clue to separate these species. There is nevertheless some variation, especially in M. laevigella. Both male and female genitalia vary considerably, as do those of M. laevigella. The variation in all characters of genitalia overlaps between these species, and, apparently, they cannot be identified by genital characters. For variation of M. laevigella see also Gaedike (2019). Moreover, M. weaverella (Scott, 1858) and M. neglecta Sumpich & Liska, 2011 may occasionally fall within the morphological variation of these two species, especially in females. The males of M. weaverella and M. neglecta can however be distinguished from M. laevigella and M. jussii by the shape of gnathos, best decipherable in lateral view (see Gaedike 2019): gnathos arms are straight, triangular in M. weaverella and M. neglecta, angled particularly in anterior margin in M. laevigella and M. jussii.	en	Mutanen, Marko, Huemer, Peter, Autto, Jonna, Karsholt, Ole, Kaila, Lauri (2020): Monopis jussii, a new species (Lepidoptera, Tineidae) inhabiting nests of the Boreal owl (Aegolius funereus).

BB76B4A7871054829F0E253DFB129B03.taxon	description	Description. Forewing length 5.8 - 8.5 mm (n = 8 ♂ and 8 ♀) (note that the specimens are reared which may have affected their size). Maxillary palpus, labial palpus and head ochreous yellow; outer side of labial palpus with dark grey scales, second segment distally bristled. Scape of antenna ochre with pecten formed of bristle-shaped scales, pedicel and flagellum dark brown. Thorax dark grey, dorsomedially variably intermixed or entirely with pale ochre scales; tegula dark grey, apically often paler grey or ochre. Fore and mid leg inwardly ochre, outwardly leaden grey, apex of tibia and tarsal segments ochre. Hind leg inwardly pale, outwardly ochre, intermixed with grey scales; spurs and apex of tibia and tarsal articles ochre. Forewing dark grey, variably mottled with pale grey scales; costa narrowly and variably sometimes ochre; basal scales of termen with alternating pale ochre and grey scales, distal scales of termen unicolorous grey, contrast between distally paler basal scales and darker distal scales giving an impression of faint fringe line; silvery grey spot somewhat basal of middle of wing length at fold. Hind wing bluish grey with somewhat darker grey veins; fringe basally narrowly ochre, otherwise grey. Underside of wings grey with ochre margin; underside of hindwing dark grey along costal margin. Abdomen leaden grey, basal segments ventrally more or less ochre. Male genitalia (Figure 6). Uncus elongate, triangular, laterally with long, hair-like scales, distally pointed, bifid. Gnathos arms angled in the middle, tapered toward hook-shaped apex. Basal and distal margins of tegumen reinforced, U-shaped, anterior margin more deeply. Shape of valva highly variable, gradually varying from ovoid and basally broadest to somewhat elongate and medially widest; distally round. Every aspect of saccus variable; straight or somewhat undulate, apically little or very much widened; length also very variable. Phallus straight and nearly parallel-sided, slightly widened at basal 1 / 3; length compared to that of saccus impossible to establish due to variation in length of saccus. Phallus distally inserted in cylindrical, internally spinose anellus. Vesica distally densely spinose, devoid of cornuti. Female genitalia (Figures 7 - 9). Papilla analis membranous, elongate, distally round, with a few setae. Apophysis posterioris as long as segments 7 + 8, posteriorly starting as continuation of papilla analis, slender, anteriorly slightly widened, apex cut. Apophysis anterioris 1 / 3 length of and slightly stouter than apophysis posterioris, twice as long as 8 th segment, distally not widened. Ovipositor telescopic, with two retractile nodes; with a few stout setae. Ventral pseudapodemes (sensu Davis and Robinson 1999) not decipherable. Tergum 8 posteriorly somewhat sclerotized. Ostium a widely U-shaped opening, laterally bordered as posteriorly curved rim, laterad shallowly emarginated in posterior direction, emargination with a few long setae; devoid of microtrichia but minutely granulose. Length of antrum variable, narrowed toward colliculum; colliculum tubular, length variable, 2 - 4 times as long as wide, usually narrowed in the middle. Ductus bursae between colliculum and corpus bursae membranous, as long as apophysis anterioris. Corpus bursae oval, 3 times as long as wide; in approximately the middle to posterior 1 / 3 ca. 12 elongate, sharply spicular or dentate signa forming transverse band.	en	Mutanen, Marko, Huemer, Peter, Autto, Jonna, Karsholt, Ole, Kaila, Lauri (2020): Monopis jussii, a new species (Lepidoptera, Tineidae) inhabiting nests of the Boreal owl (Aegolius funereus).

BB76B4A7871054829F0E253DFB129B03.taxon	description	Genetic characterisation. Clearly distinguishable by its DNA barcode from all other species of Monopis barcoded globally so far (Figure 1). Genetically the closest species with a minimum divergence of 4.43 % is M. laevigella. Intraspecific divergence among four barcoded specimens from Finland and Italy is 0.15 %. Additionally, the species show 1.5 - 4.1 % interspecific divergence in the nuclear genes of CAD, EF- 1 a, MDH and wingless (Figure 2).	en	Mutanen, Marko, Huemer, Peter, Autto, Jonna, Karsholt, Ole, Kaila, Lauri (2020): Monopis jussii, a new species (Lepidoptera, Tineidae) inhabiting nests of the Boreal owl (Aegolius funereus).

BB76B4A7871054829F0E253DFB129B03.taxon	etymology	Etymology. The species is dedicated to Dr Juhani (Jussi) Itaemies, a Finnish expert of Lepidoptera who, as far as we know, is the first to have reared this species. He has also spent most of his life on faunistic research of Finnish Lepidoptera and has done incredible work in elucidating the life history of numerous microlepidopteran species.	en	Mutanen, Marko, Huemer, Peter, Autto, Jonna, Karsholt, Ole, Kaila, Lauri (2020): Monopis jussii, a new species (Lepidoptera, Tineidae) inhabiting nests of the Boreal owl (Aegolius funereus).

BB76B4A7871054829F0E253DFB129B03.taxon	distribution	Distribution. From our available observations M. jussii seems to have a boreo-montane distribution pattern. It is widely distributed in Finland and also recorded from Norway (Finnmark) and Sweden (Haerjedalen). Records from the Alps seem rare with a proved, barcode-based locality in the Italian Dolomites and two further unpublished records (ZSM, A. Segerer) in the Bavarian Alps.	en	Mutanen, Marko, Huemer, Peter, Autto, Jonna, Karsholt, Ole, Kaila, Lauri (2020): Monopis jussii, a new species (Lepidoptera, Tineidae) inhabiting nests of the Boreal owl (Aegolius funereus).

BB76B4A7871054829F0E253DFB129B03.taxon	biology_ecology	Biology. So far reared on five different occasions from the nest bottoms of the Boreal owl (Aegolius funereus). Two specimens in the collection of ZMUO have been reared from the nest of the Ural owl (Strix uralensis) and one specimen from the nest of the Great tit (Parus major). Additionally, three reared specimens of two different rearing events do not state anything about the origin. One specimen has been found in a vacated house. Thirteen specimens in coll. ZMUO and a specimen from the Italian Alps in coll. TLMF have been collected in the wild between 17 June to 21 July, which matches well with the flight time of other Monopis species of these regions.	en	Mutanen, Marko, Huemer, Peter, Autto, Jonna, Karsholt, Ole, Kaila, Lauri (2020): Monopis jussii, a new species (Lepidoptera, Tineidae) inhabiting nests of the Boreal owl (Aegolius funereus).
