During investigations of lepidopterous needle-miners and bud-borers on spruce in the Province of Quebec between 1956 and 1959, four closely-related species belonging to the family Gelechiidae were found. One of the species, atrupictella, is the type of the genus Eucordylea Dietz (1900); a second, piceaella (Kft.) has been formerly assigned to the genus Recurvaria Haworth, and the remaining two were undescribed entities. In this paper, the four species are assumed to be congeneric and are tentatively assigned to Eucordylea Dietz. However, there is considerable confusion regarding the taxonomic status of this group and further generic divisions may be justified in future (Freeman 1960).
The present study deals with a comparative morphology of the adult and immature stages of the four species; the life history and general biology of each will be considered in separate publications.
The study was conducted as a project within the Forest Entomology and Pathology Branch, Department of Forestry, from the Forest Research Laboratory in Quebec City. Field work was carried out in diverse localities within the Province but mainly concentrated in the Gaspé Peninsula and in southwestern Quebec.
