Comprehensive account of characters of all hierarchically subordinated mayfly taxa higher than species (except for subordinated taxa of Baetidae s.str. and Leptophlebiidae). The book contains complete lists of formal species names of mayflies of the world (except for Baetidae s str. and Leptophlebiidae), with recent conclusions about status and systematic position of each.
From the reviews: "This volume by Nikita Kluge of the St. Petersburg State University, Russia, has been one of the most anticipated among ephemeropterists ! . is an important milestone in Ephemeroptera phylogeny and should be mandatory reading for everyone interested in mayfly systematics. It is mainly an enumeration of the putative apomorphic characters of fossil and extant mayfly taxa, mostly accompanied by excellent line-drawings, which are very informative. However in my opinion, Kluge's nomenclature is ... used as a tool by scientists for communicating with one another." (T. Soldan, European Journal of Entomology, Vol. 104, 2007)
