''Agabus'' is a large genus of predatory aquatic beetles in the family Dytiscidae, proposed in 1817 by William Elford Leach〔(''Zool. Misc.'', 3 ): 69, 72. Type species: ''Agabus paykullii'' Leach, 1817 (= ''Dytiscus serricornis'' Paykull, 1799)〕 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 Afrotropic and Neotropic realms.〔Ross H. Arnett, Michael C. Thomas (2002). ''(American Beetles: Staphyliniformi )''. Boca Raton, FL: CRC Press. ISBN 0849319250. P. 175-176.〕〔Anders N. Nilsson, Mogens Holmen (1995). ''(The Aquatic Adephaga (Coleoptera) of Fennoscandia and Denmark: II - Dytiscidea )''. Leiden - a.o.: Brill. ISBN 9004104569. P. 87.〕 Three species of ''Agabus'', namely ''A. clypealis'',〔Foster, G. 1996. '. In: IUCN 2008. 2008 IUCN Red List of Threatened Species. Accessed on 28 November 2008.〕 ''A. discicollis''〔Foster, G. 1996. '. In: IUCN 2008. 2008 IUCN Red List of Threatened Species. Accessed on 28 November 2008.〕 and ''A. hozgargantae''〔Foster, G. 1996. '. In: IUCN 2008. 2008 IUCN Red List of Threatened Species. Accessed on 28 November 2008.〕 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.〔 The genus is probably polyphyletic or paraphyletic.〔 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.〔Ignacio Ribera, Anders N. Nilsson, Alfried P. Vogler (2004). Phylogeny and historical biogeography of Agabinae diving beetles (Coleoptera) inferred from mitochondrial DNA sequences. ''Molecular Phylogenetics and Evolution'' 30 (3): 545-562.〕 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. ''Agabus'' contains the following species: 〔(Dytiscidae Species List ) at Joel Hallan's Biology Catalog. Texas A&M University.
