230 ENTOMOLOGICAL NEWS NEW RECORDS OF MAYFLIES (EPHEMEROPTERA) FROM ALBERTA, CANADA 1 J. M. Webb : and W. P. McCafferty' ABSTRACT: Eleven species of Ephemeroptera are reported from Alberta for the first time. Among them, the reports ofAmetropus ammophilus and Baetisca columbiana also represent the first records from Canada. The validity of B. columbiana and the status of the genus Baetisca in western North America are discussed. A total of 122 mayfly species are now known from Alberta. KEY WORDS: Ephemeroptera, mayflies, Alberta (Canada), new records. In their compendium of Canada mayflies, McCafferty and Randolph (1998) reported 102 species of mayflies from Alberta, Canada. Jacobus and McCafferty (2001) reported an additional nine species [although Pseudocloeon dardamim (McDunnough) was previously reported from Alberta by Soluk (1981 )], and Sun et al. (2002) described a new species from southern Alberta. A previous report of Baetisca obesa (Say) from Alberta by Lehmkuhl (1972) is applicable to B. lau-rentina McDunnough (Pescador and Berner 1981) and should not be included in the Alberta species list. This brought the total number of species known from Al-berta prior to this study to 111. Herein, we report an additional 1 1 species. Collec-tions were made by, and are in the possession of, JMW, unless otherwise indicat-ed as being deposited in the Purdue Entomological Research Collection (PERC).
