Catoptria trichostomus ( Christoph, 1858)

( Figs 9, 10 , 41 , 49 )

Crambus trichostomus Christoph, 1858 . Type locality: [ Canada, Newfoundland and Labrador] Labrador. Type material: ZISP. Catoptria tristis Kirpichnikova, 1994: 128 . Type locality: Russia, Koryak Autonomous Okrug, Apuka e Magadan Region,

Tenkinsky District. Type material: ZISP. Sinev 2008, Catalogue Lepidoptera Russia: 174, 334 (syn. n. of C. trichostoma ).

Material examined: Canada: 1 male, Head of Clyde Inlet , Baffin Id, N.W. T ., 29.vii.1950, Wynne Edwards leg, GS 3034 GB, NHMUK ; 1 female, Baffin I., Cumberland Peninsula , Penny Highland area, 24.vii.1953, A. Watson leg, GS 3035 GB, NHMUK ; Russia: 1 male, Sarepta , ex Coll. C. Reutti, GS 1366 GB, SMNK ; 1 female, Polar – Ural , 9.vii.1977, leg. K.F. Sedych, GS 4348 GB, RCGB .

Diagnosis: The habitus of C. trichostomus ( Figs 9, 10 ) is somewhat similar to that of C. hannemanni ( Figs 7, 8 ) and to that of the female of C. orientellus ( Fig. 6 ); however, the forewing has a short medial stripe interrupted by a large antemedial blackish-brown band, and a large postmedial white band angled at veins M1 and then at M2. The male genitalia ( Fig. 41 ) feature with a stocky, upturned pars basalis, the phallus with two subapical small teeth and the vesica with about twelve cornuti, are unlike those of all related species. The female genitalia ( Fig. 49 ) are similar to those of C. hannemanni ( Fig. 50 ) and C. spodiellus ( Fig. 48 ); however, the sterigma is produced and bilobed, and the ductus bursae is slightly sclerotized and strongly enlarged basally, as opposed to the sterigma being simple, with lateral cup-shaped projections, and the ductus bursae being less enlarged basally, strongly sclerotized and wrinkled in C. hannemanni and the sterigma being notched and rounded with a ductus bursae slightly sclerotized and narrow in C. spodiellus .

Distribution: Holarctic species: Canada, polar Russia, USA: Alaska. The examined male labelled “Sarepta” ( Volgograd Oblast) is possibly mislabelled. Detailed distribution in Russia in Streltzov (2010, Fig. 1 ).
