Flightless beetles in Appalachian “deserts”: studies on the distribution and localized habitats of some ... TenebrionidaeBy W.E. Steiner
Virginia Museum of Natural History Special Publication 7: 125-144, 1999
Abstract: Flightless species of darkling beetles Coleoptera: Tenebrionidae and Zopheridae of the Appalachian region belong to the genera Ammodonus, Blapstinus, Eutochia, Helops, Meracantha, Opatrinus, Paratenetus, Phellopsis and Polypleurus. Collection records and field observations show that Appalachian "microdeserts" - the dry sandy deposits, shale barrens, and rock outcrops - are isolated habitats for a few odd species that appear to have disjunct populations and unexpected range extensions in the region. This study reviews the known distribution of these insects and their sister taxa, recognizes some distinct species assemblages, and hypothesizes the origins of present distribution patterns.
