The numerous sigalionid species described originally as members of the genus Leanira Kinberg, or subsequently referred to it, form a heterogeneous group. Among them, two closely related groups are recognized and assigned to two genera: Leanira Kinberg, limited, consisting of seven species, one of which is new, and one synonym, and Ehlersileanira, new genus, comprising a single species and three synonyms. Definitions of the two genera, with a key to the species of Leanira, are followed by redescription of the species, based in large part on examination of the type-specimens.
