Noteridae (Coleoptera: Adephaga), also known as the burrowing water beetles, comprises a widely distributed family of about 270 described species. Our current understanding of noterid evolution and diversity remains nebulous, and a robust molecular-based phylogenetic analysis of the family has never been performed. Here we present a phylogeny of noteridae inferred from molecular sequence data of 5 gene fragments from a sampling of over 70 noterid exemplars, including representatives for 16 of the 17 known noterid genera. Our analyses provide the most robust estimate of the evolutionary relationships of noteridae to date, strongly contradicting morphology based reconstructions. Resulting phylogenetic trees and recovered relationships are presented and noterid classification is discussed.
