Evolution and taxonomy of Andogyrus Ochs (Coleoptera: Gyrinidae)
Abstract Analysis of relevant structures showed that there are three evolutional lineages in Andogyrus. Two have remained in southernmost South America, near the ancestral area of the genus (probably the Antarctic). One lineage has spread northwards and radiated in the Andes. There is a parallel ana...
