DeinopsisJames S. Ashe (1947-2005) and Stylianos Chatzimanolis
This tree diagram shows the relationships between several groups of organisms.
The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.close box
Species of Deinopsis are small to medium-sized (2.1-4.2 millimeters), teardrop-shaped aleocharines that are found in vegetation, detritus and mud in swampy and marshy areas around ponds, lakes, sphagnum bogs and slow-moving streams. Most species are found in the Holarctic (Nearctic and Palearctic) faunal region, but one species (D. queenslandica) is found in Australia.
Adults of Deinopsis can be distinguished from other Deinopsini by the combination of: 3-3-3 tarsal formula and antennal segment XI without apical papilla. Klimaszewski (1979) provides descriptions, distributional information, illustrations of structural features, and a key for identification of most species of Deinopsis.
Klimaszewski (1979) provided the only available phylogeny for species of Deinopsis. Beacuse adults of Deinopsis are externally extremely similar, the phylogeny is based on characteristics of the terminalia and genitalia. This phylogeny indicates that the Australian species (D. queenslandica) is the sister group to all other Deinopsis; the North American taxa (D. rapida - D. texana clade) is a monophyletic lineage, and the Japanese species (D. minor and D. modesta) form a clade with the European species (D. pulawskii and D. erosa). However, this phylogeny contains a number of poorly supported branches and needs reevaluation using modern methods of character and phylogenetic analysis. Later, Klimaszeski (1980, 1982) and Klimaszeski and Frank (1992) described additional new species.
