It contains at least one species, ''N. schucherti''; ''N. kistneri'' resembles this, but it probably belongs to a distinct genus and may not be closely related. Both are known from the Late Wasatchian (51-52 MYA) stratum of the Early Eocene Green River Formation of the Western-Central USA. ''"N." kistneri'' is known from one fairly complete, but not very well preserved skeleton, whereas of ''N. schucherti'' even less material was found. The systematic assignment of the genus (apart from the problems posed by ''"N." kistneri'') is not well resolved. Initially, the genus (at that time only comprising the type species) was considered to be a passeriform. ''"N." kistneri'' was described 60 years later as a species of the genus ''Primobucco'', which then thought to be related to woodpeckers because it had a zygodactyl foot or at least could turn the outer toe backwards; some years later, several genera (including ''Primobucco'' and ''Neanis'') were put into a new family, the Primobucconidae, which were thought to be a primitive kind of puffbird. However, it is now known that the primobucconids as originally defined were a paraphyletic assemblage including taxa as diverse as Coliiformes and Coraciiformes. Indeed, the only remaining genus of the family is ''Primobucco'' (without ''kistneri''), and the family as such has been moved to the Coraciiformes. The closest relatives of ''Neanis schucherti'' may be the Piciformes, or it might be an ancestral form in the piciform-coraciiform radiation. ''"N." kistneri'' seems more closely related to piciform birds. ''Neanis schucherti '' appears to share some traits with ''Hassiavis'' and might even be a cypselomorph ==References== * Shufeldt, W.
