Redescription of Haliplus dorsomaculatus (Coleoptera: Haliplidae) with a New Synonymyand Comments on Habitat and Distribution

Rex D. Kenner


Adults of Haliplus dorsomaculatus Zimmermann are redescribed including a discussion of male and female morphological characters. The species ranges from southern British Columbia east to western Montana and south to northeastern Utah and northern California; there is little geographic variation. Its preferred habitat appears to be emergent vegetation near the margins of slowly flowing water. Haliplus allisonae Brigham is a junior synonym of H. dorsomaculatus.
