A newly discovered larva of Baetidae (Insecta, Ephemeroptera) is described from Nunavut, Canada as Kirmaushenkreena zarankoae, n. gen. and n. sp. The new taxon has a unique combination of generic characteristics, including unusual claw armature that is diagnostic. Closest relatives of the new genus may possibly be in the Indobaetis complex of genera. The absence of a villopore sets the new species apart from other far northern North American baetine species, and other differences and convergent similarities such as claw setation and gill dimensions among that fauna are discussed.
