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. [1]

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 junior homonym and needed to be replaced. [2] The name Plaesiorrhina had been published by John O. Westwood several months prior to Burmeister's publication, [3] a fact that previous researchers had been unaware of, and Krikken renamed Burmeister's genus Plaesiorrhinella. [2] At the same time, Krikken also recognized that the other Burmeister genus, Bothrorrhina, was a junior objective synonym of Westwood's resurrected genus Plaesiorrhina , necessitating a change in combination for all of the included species. [2]

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. [4] 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. [4]

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. [5] [6] ), 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. [7] [8] [9] [1] ), 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.

Euphoria is a genus of scarab beetles in the subfamily Cetoniinae, the flower or fruit chafers. They are native to the Americas, where they are distributed from Canada to Argentina. They are most diverse in Mexico and Central America. As of 2012, there are 59 species in the genus.

<span class="mw-page-title-main">Flower chafer</span> Subfamily of beetles

Flower chafers are a group of scarab beetles comprising the subfamily Cetoniinae. Many species are diurnal and visit flowers for pollen and nectar, or to browse on the petals. Some species also feed on fruit. The group is also called fruit and flower chafers, flower beetles and flower scarabs. There are around 4,000 species, many of them still undescribed.

<i>Ischiopsopha</i> Genus of beetles

Ischiopsopha are beetles from the subfamily Cetoniinae, tribe Schizorhinini. The genus was created by Raffaello Gestro in 1874. The type species of the genus is Cetonia bifasciata Quoy & Gaimard, 1824. These cetoniids have only the tip of the scutellum visible. The genus is widespread throughout the whole Australian region.

<i>Trichostetha</i> Genus of beetles

Trichostetha is a genus of beetle in the scarab beetle family. It is endemic to southern Africa, and its species most commonly occur in mountainous terrain. The genus includes several species that have only recently been described, as well as many species lacking a description of any of the larval stages. Except for T. fascicularis and its subspecies, the species comprising Trichostetha have small ranges of distribution, frequently in the Cape Floral Region of South Africa. The genus is believed to be related to Odontorrhina.

Odontorrhina is a genus of flower chafer beetles comprising four species and two subspecies. The bodies of all species are heavily covered with small bristles (setae), and they are believed to be most closely related to the genus Trichostetha. Members of the genus have been recorded exclusively from the South African provinces of the Northern and Western Cape, aside from one unconfirmed record from southern Namibia. They are endemic to the Fynbos and Succulent Karoo regions.
