Agabus (beetle)
Agabus is a large genus of predatory aquatic beetles in the family Dytiscidae, proposed in 1817 by William Elford Leach[1] and named after Agabus, an early follower of Christianity. The adult beetles are moderate-sized, 5 to 14 mm long. The genus is primarily Holarctic in distribution, with only a few species known from the Afrotropical and Neotropical realms.[2][3] Three species of Agabus, namely A. clypealis,[4] A. discicollis[5] and A. hozgargantae[6] are endangered according to the IUCN Red List. The division into subgenera is not widely accepted. However, a number of species groups are recognized after the works of David J. Larson and Anders N. Nilsson.[3] The genus is probably polyphyletic or paraphyletic.[2] In a recent study of mitochondrial DNA, Agabus was found paraphyletic with respect to several of the species groups of Platambus, a closely related genus in the tribe Agabini.[7] Lately the taxonomy of the genus has been revised, and some groups of species were transferred from Agabus sensu stricto to other genera in the tribe Agabini.[8]
