Introduction
According to REGIER et al. (2015) the Douglasiidae together with the Millieriidae are a member of an unassigned superfamily, located between Gracillarioidea and Hyblaeoidea. Hitherto 32 species (23 from the Palaearctics, 8 from the Neotropics and 1 from the Australis) are known worldwide.
The study of still undetermined material of this family has allowed us to describe some new members of the genus Tinagma Zeller, 1839 and to establish some new country records.
For the loan of this valuable material I wish to thank the late Jukko Jalava from the Finnish
Museum of Natural History in Helsinki, Finland (FMNH), Ole Karsholt from the Zoological Museum in Copenhagen, Denmark (ZMUC) and Giorgio Badizzone, Asti, Italy. For making the colour pictures I thank Christian Kutzscher from the Senckenberg Deutsches Entomologisches Institut in Müncheberg, Germany (SDEI).

Diagnosis: Superficially distuingishable from the other species, described below, by the colouration of forewings. Somewhat similar to T. mongolicum Gaedike, 1991, but the pattern of forewing of that species is more greybrown and the apical fourth is completely brown.
Description (Fig. 1): Wingspan 11 mm; head, thorax and tegulae with white scales with grey tip, labial palpus curved up, white, scales on second segment long, directed downward, with grey tips, third segment thin, short; scape of antenna with white-grey scales too, flagellum light grey, ringed; forewing on white groundcolour with a goldenbrown pattern: a broad strip between 1/3 and 1/2 from costa to dorsum, parallel sided, at edge on dorsum with some dark, nearly black scales, an oval patch from end of cell directed oblique to costa at 3/4, prolonged to beginning of fringe as short strip, more or less covered by blackish scales; fringe greyish, overlaid partly with white scales with black tip, apex with a dark Brown dot; the space between broad strip and patch, and between patch and apex, white, only some dark tips are visible; basal third with white-grey scales, only the border to the strip white; hindwing light creamy.
Male genitalia (Fig. 6): Vinculum band-shaped, saccus as broad as vinculum, long, with rounded tip; valva broader than long, broadest at base, costal edge apically rounded to oblique apical edge, ending in a short finger-like process, ventral edge at basal half folded, on inside, along the middle of the apical edge, a field of numerous long strong sclerotized bristles, apodeme long and thin; phallus two times longer than valva, from base narrower to pointed tip, with minute sclerotizations in the vesica.

Gaedike 2017;” FMNH; Paratypes: 3 ♂♂, same dates, two of them with genitalia slides Gaedike Nr. 5709 and 5711; FMNH, SDEI.
Diagnosis: See under mikkolai.
Description (Fig. 3): Wingspan 9-11 mm; the whitish base of scales on head, thorax and tegulae nearly complete overlaid by dark grey, labial palpus short, straight, on inside more whitish, flagellum of antenna ringed, underside of scape and first half of flagellum whitish; forewing on basal third with same colouration as thorax, followed by a nearly complete dark grey band with indistinct basal border, api al half more whitish, at the end of cell one dark grey patch, apex with dark dot, fringe overlaid with long white scales with dark tip; hindwing grey.
Male genitalia (Fig. 8): Vinculum band-shaped, with long saccus with rounded tip; valva nearly squar , somewhat broader than long, basal edge a little curved inward, apical edge oblique from costal edge to the finger-like process, along ventral edge an indication of fold; on inside a field of strong sclerotized bristles with acute tips; phallus nearly three times longer than broadness of valva, straight, with pointed tip.

Diagnosis: The nearly unicoloured forewing make the species distuingishable from the other species here described. In male genitalia the valva with the long narrow finger-like process and the large field of long pointed bristles is characteristic.
Description (Fig. 4): Wingspan 10-12 mm; head, thorax and tegulae dark greybrown, tips of scales light grey, labial palpus short, with same colouration, second segment ventrally with longer scales, scape of antenna somewhat ringed; forewing nearly complete unicoloured dark greybrown, apex with a small dark dot, wing between 1/2 and 3/4 lighter, border to base as an oblique whitish stripe; hindwing with same colouration as forewing.
The colouration of the specimen from Barguzin range is lighter, the tips of scales are whitish, the lighter aerea on forewing with more clear border to base.
Male genitalia (Fig. 9): Vinculum band-shaped, saccus long, narrow, with rounded tip; valva broader than long, base straight, costa somewhat oblique to rounded edge, apical edge curved to long apical process, ventral edge longer than costal edge, inside with fold; on inside along the main part of apical edge a field of long, thin, strong sclerotized pointed bristles; phallus nearly three times longer than valva, slightly curved.
Female genitalia: Unknown.
Etymology: Named after Jakko Kullberg, one of the collectors of the type series. Remark: Although the colouration of the specimen from Barguzin range is somewhat different to the colouration of the other specimens, the genitalia structure is completely the same, only the size is smaller.
