Taxonomy

''Pedinorrhina'' is one of a small set of closely related African genera whose constituency is considered controversial, due to historical and ongoing discrepancies in treatment by various authorities. Up until 1984, taxonomists considered there to be six distinct genera in this group (''Bothrorrhina'' Burmeister, '' Chondrorrhina'' Kraatz, ''Dyspilophora'' Kraatz, ''Pedinorrhina'' Kraatz, ''Plaesiorrhina'' Burmeister, and ''Taeniesthes'' Kraatz), but in 1984, Jan Krikken recognized that Burmeister's genus name ''Plaesiorrhina'' was a

The name ''Plaesiorrhina'' had been published by John O. Westwood several months prior to Burmeister's publication,Bousquet, Y.

'', necessitating a change in combination for all of the included species. In 1994, Holm suggested a novel set of relationships, proposing that Krikken's genus ''Plaesiorrhinella'' (Burmeister's genus ''Plaesiorrhina'') was a synonym of ''Pedinorrhina'', while ''Dyspilophora'' and ''Taeniesthes'' were both synonyms of ''Chondrorrhina'', and placing ''Chondrorrhina'' as a subgenus of ''Pedinorrhina''.Holm, E. (1994) On the genera of African Cetoniinae 1: The genus ''Pedinorrhina'' Kraatz and related taxa (Coleoptera: Scarabaeidae). ''The Coleopterists Bulletin'' 48(1): 19-29 These changes reduced six genera down to only two: ''Pedinorrhina'' Kraatz, and ''Plaesiorrhina'' Westwood, with the latter having the same name as a previously recognized genus by a different author. Holm also treated six former species as new junior synonyms, so under his revised definition of ''Pedinorrhina'', there were 16 species rather than 22. Subsequent authors have largely disagreed with Holm's classification, treating ''Chondrorrhina'' as a valid genus separate from ''Pedinorrhina'', and placing Krikken's genus ''Plaesiorrhinella'' as a subgenus of ''Chondrorrhina'' (e.g.), thereby recognizing a total of three genera (''Chondrorrhina'' Kraatz, ''Pedinorrhina'' Kraatz, and ''Plaesiorrhina'' Westwood). It is this classification, with these three genera, that has been adopted by the majority of recent researchers (e.g.Beinhundner, G. (2017) The Cetoniinae of Africa (Coleoptera: Scarabaeidae). Privately published, Euerbach, 1199 pp.Garnier, T., Flutsch, G. & Rojkoff, S. (2018).

''Cetoniimania'' NS, 13: 17-30.), retaining ''Chondrorrhina'' as a genus distinct from ''Pedinorrhina''. In this restricted sense, there are only seven species recognized within ''Pedinorrhina'', and a number of the species that Holm had synonymized have been treated as valid, many no longer in ''Pedinorrhina''.
