(excerpt) Members of the genus Axonopsis have a broad zoogeographic distribution but are unreported from the Australian region and South America south of Colombia. Species occur in permanent standing waters and streams (including interstitial water). Representa- tives of four subgenera, Axonopsis s. s., Brachypodopsis, Paraxonopsis and Vicinaxonopsis, have been collected in North America, and a species of the closely related genus Erebaxonopsis is also known from interstitial waters in California. The only anomalous aspects of the distributional patterns are the apparent absence of Hexaxonopsis (which has a relatively widespread Palearctic range) and the stream (and interstitial) habitat of the North American species of the typical subgenus. The European species occurs only in lakes.
