The Society attempts to facilitate the exchange of ideas and information in both amateur and professional circles, and encourages the study of insects by youth. Membership in the Society, which serves the :'{orth Central States and adjacent Canada, is open to all persons interested in entomology. There are four paying classes ofmembership: Stndent (to 12th gradel-annual dues $5.00 Active--annual dues $15.00 Institutional-annual dnes $35.00 Sustaining-annual contribution $25.00 or more Life-$300.00 Dues are paid on a calendar year basis (Jan.

'The Michigan Entomological Society 2001 THE GREAT LAKES ENTOMOLOGIST COMMENTARY ON AMETROPUS SPECIES (EPHEMEROPTERA: AMETROPODIDAE) IN NORTH AMERICA w. P. McCaffertyl ABSTRACT Ametropus albrighti is shown to be a junior subjective synonym ofA. neavei, n. syn. Ametropus neavei sensulato demonstrates stable structural character istics with respect to male genitalia and larval morphology, whereas degree of maculation and therefore abdominal patterning varies both among populations and within populations. Ametropus ammophilus is distinctive, and the two North American species are apparently allopatric based on known distribu tions, which are reviewed. The Holarctic mayfly genus Ametropus Albarda was originally discov ered in Europe (Albarda 1878) and is now known from Asia and North America as well. Bengtsson (1913) placed this distinctive genus in a separate higher taxon Ametropodidae (originally spelled Ametropidae) where it has resided ei ther at the family or subfamily level ever since. McCafferty (1981) referred to these mayflies as the sand minnow mayflies because of the peculiar adapta tions of the larvae for life in sand substrates of rivers (e.g., Soluk and Craig 1988), and workers in general have regarded the group's relationships to be with the pisciform mayflies (e.g., Edmunds et al.1976, McCafferty 1991). McDunnough (1928) first discovered the genus in North America. His report was based on a single female adult from Alberta that he described as Ametropus neavei McDunnough. Traver (1935) described a second species, A. albrighti Traver, based on a series oflarvae taken from the San ,Juan River in extreme northwest New Mexico. Edmunds (1954), Woodbury and Argyle (1963), and Pearson et al. (1968) all referred to additional larval populations of A. albrighti from the Green River in northeastern Utah. Newell (1970) listedA. neavei from Montana but provided no substantiating locale data (presumably he saw a female adult that matched McDunnough's [1928] description). Allen and Edmunds (1956) listed an unnamed species of Ametropus from Oregon, and later Allen and Edmunds (1976) described that species asA. ammophilus Allen and Edmunds based on male and female adults and larvae from Oregon, Washington, and western Montana. At the same time, Allen and Edmunds (1976) described the male adult and female subimago of A. albrighti, and pro vided additional records of that species from northwestern Utah, northeastern Colorado, and southwestern Wyoming. Allen and Edmunds (1976) also pro vided descriptions of the male adult and larva of A. neavei for the first time, along with a record of the species from Saskatchewan. Allen and Edmunds (1976) concluded thatA. neauei was restricted to Alberta and Saskatchewan; thatA. albrighti was restrictcd to the Colorado River Drain age System in Colorado, New Mexico, Utah, and Wyoming; and that A. ammophilus was restricted to Oregon, Washington, and areas east to western Montana. Subsequentto the review ofthe genus Ametropus in North America by Allen and Edmunds (1976), however, several additional reports under the vari ous species names were forthcoming. Ametropus albrighti was reported from Saskatchewan by Lehmkuhl (1976a) and by Dosdall and Lehmkuhl (1989). Ametropus ammophilus was reported from northern California by Allen (1977). Ametropus neavei was reported from additional localities in Alberta by Clifford ]Department of Entomology, Purdue University, West Lafayette, IN 47907, [email protected] 2 THE GREAT LAKES ENTOMOLOGIST
