Olethreutes bowmanana (McDunnough 1923) (Fig. 1) Argyroploce bowmanana McDunnough, 1923. Canadian Entomologist 55: 165–166 (Type locality: Canada, Alberta, Nordegg [Holotype: CNCO]). Material examined. 1 ♂ (holotype), No. 607, [Canada], Alta [Alberta], Nordegg, 23.vii. 1922, K. Bowmann leg. [coll. CNCO]. Remarks. This species was described by McDunnough (1923) on the basis of the wing pattern and assigned to Argyroploce Hübner, [1825]. Heinrich (1926) treated Argyroploce as a junior synonym of Olethreutes Hübner, [1822], and provided only a short diagnosis, without a detailed illustration of the male genitalia. Hannemann (1961) rejected Heinrich’s (1926) opinion and treated Argyroploce as a separate genus. Falkovitsh (1965, 1966) followed Hannemann (1961) and described two species, Argyroploce magadana and A. kamtshadala, both from Russia. In his monograph on the Tortricidae of the Russian Far East, Kuznetzov (2001) also treated Argyroploce as a separate genus and noted that the Russian tundra species A. magadana is replaced in North America by the related A. bowmanana. Based on a study of the type material of O. bowmanana, we conclude that this species indeed bears a strong similarity with, and is probably related to O. magadana and O. kamtshadala. A redescription of O. bowmanana is given below with a special emphasis on the characters shared with the Palaearctic species. Description. Forewing length 8 mm. Head: Vertex and palpi with a mixture of blackish and grayish scales. Antennae dark gray, about half a long as forewing. Thorax: Concolorous with head. Forewing elongate, with costa nearly straight, termen oblique and straight, dorsal angle rounded; upperside ground color grayish brown, with distinct pattern; basal, median and postmedian fasciae well defined, with narrow dark striae between them; subbasal fascia narrow, curved in median cell, broader dorsally, with outer margin distinct; median fascia narrow; outer margin distinct, fissured, with a process beyond whitish discal spot; postmedian fascia divided ...
