Research by Grey Gustafson, Ph.D., a postdoc studying with Andrew Short, coauthored by Alexander A. Prokin, Rasa Bukontaite, Johannes Bergsten & Kelly B. Miller, entitled "Tip-dated phylogeny of whirligig beetles reveals ancient lineage surviving on Madagascar” has been published in Scientific Reports. 

The study reveals the oldest endemic lineage of animal or plant currently known from Madagascar, the Malagasy striped whirligig beetle, which lives on the surface of water, and has many interesting adaptations for life on the surface of water including four eyes and paddle-like legs. On Madagascar, the striped whirligig beetle is only known from small mountain streams in a few areas in the mountainous region of the southeastern part of the island. The study shows the striped whirligig beetle is not only a relict, but the last surviving member of a group of whirligig beetles that were dominant during the Mesozoic Era. Similar to the Tuatara lizard of New Zealand, the Malagasy striped whirligig beetles survive solely on an isolated island while its other continental relatives went extinct. These findings are especially exciting because there are no other such examples known from Madagascar, despite its lengthy isolation following the breakup of Gondwana over 90 million years ago.
