A new species of the genus Alainites Waltz & McCafferty, 1994 (Ephemeroptera, Baetidae) from the north of Morocco

Abstract

A new species of Alainites is described from northern of Morocco Alainites albaisp. nov. It can be separated from the other west Palearctic species by the gill number, the spination of the distal margin of tergites, the leg setation, and the paraproct shape and spination. This species is widespread in the study area but never abundant. It prefers small to medium streams with slow flow, and does not seem to be very sensitive to pollution and water logging activities.
