The taxonomic status of Pelidnota gounellei (Ohaus, 1908) and Pelidnota ludovici Ohaus, 1905 (Coleoptera: Scarabaeoidea: Melolonthidae)

ABSTRACT The taxonomic status and the geographic distribution of two species, Pelidnota gounellei (Ohaus, 1908) and P. ludovici Ohaus, 1905, is revised and the species are revalidated. A lectotype for Pelidnota tricolor Nonfried, 1894 is designated. The taxonomy of the species is briefly discussed, and a distribution map for the reviewed species is also provided. The distribution range of P. gounellei is expanded to the Minas Gerais state, Brazil.

A checklist of Rutelinae MacLeay, 1819 (Coleoptera, Melolonthidae) of Bahia, Brazil / Um checklist dos Rutelinae MacLeay, 1819 (Coleoptera, Melolonthidae) da Bahia, Brasil

Abstract A list of species of Rutelinae from Bahia state, Northeastern Brazil, is presented. The list is based on specimens deposited in Brazilian collections. The list includes 4 tribes, 23 genera, 101 species and 17 subspecies. The genera Byrsopolis Burmeister, 1844, Pseudodorysthetus Soula, 2008 and Trizogeniates Ohaus, 1917 are recorded for the first time in Bahia and Northeastern Brazil. Thirty species are newly recorded in Bahia: Areoda espiritosantensis Ohaus, 1905, B. laticollis Burmeister, 1855, Bolax flavolineata (Mannerheim, 1829), Chlorota abdominalis Ohaus, 1926, C. espiritosantensis Ohaus, 1912, Dorysthetus espiritosantensis Ohaus, 1905, D. fulgidus (Waterhouse, 1881), Leucothyreus acanthurus Ohaus, 1917, L. albopilosus Ohaus, 1917, L. campestris Burmeister, 1855, L. cayapo Ohaus, 1931, L. duplopunctatus Frey, 1976, L. eligius Ohaus, 1918, L. fluminensis Ohaus, 1918, L. iridipennis Ohaus, 1917, L. lucipetens Ohaus, 1931, L. occipitalis Ohaus, 1931, L. pallefactus Ohaus, 1924, L. paulista Ohaus, 1917, L. punctulatus Blanchard, 1851, L. suturalis Laporte, 1840, L. trochantericus Ohaus, 1917, L. verticalis Ohaus, 1924, Macraspis cincta (Drury, 1872), Paranomala tricostulata (Ohaus, 1897), P. violacea (Burmeister, 1844), Pseudodorysthetus calcaratus (Spinola, 1835), and Trizogeniates planipennis Ohaus, 1917. Pelidnota unicolor unicolor (Drury, 1778) is recorded for the first time in Bahia. Fourteen species are identified and will be described in subsequent papers: 10 of Leucothyreus MacLeay, 1819, 2 of Lobogeniates Ohaus, 1917 and 1 species of Byrsopolis Burmeister, 1844 and Pelidnota MacLeay, 1819. Rutelini is the richest tribe with 16 genera and 49 species. The information presented in the list generates an important set of knowledge regarding the diversity of Rutelinae of Bahia and Brazil and provides the basis for conducting future research within the group.

Resumo É apresentada uma lista de espécies de Rutelinae do estado da Bahia, Nordeste do Brasil. A lista é baseada em espécimes depositados em coleções brasileiras. A lista inclui quatro tribos, 23 gêneros, 101 espécies e 17 subespécies. É feito o primeiro registro para a Bahia e região Nordeste dos gêneros Byrsopolis Burmeister, 1844, Pseudodorysthetus Soula, 2008 e Trizogeniates Ohaus, 1917. Trinta espécies de Rutelinae foram registradas pela primeira vez para a Bahia e região Nordeste: Areoda espiritosantensis Ohaus, 1905, B. laticollis Burmeister, 1855, Bolax flavolineata (Mannerheim, 1829), Chlorota abdominalis Ohaus, 1926, C. espiritosantensis Ohaus, 1912, Dorysthetus espiritosantensis Ohaus, 1905, D. fulgidus (Waterhouse, 1881), Leucothyreus acanthurus Ohaus, 1917, L. albopilosus Ohaus, 1917, L. campestris Burmeister, 1855, L. cayapo Ohaus, 1931, L. duplopunctatus Frey, 1976, L. eligius Ohaus, 1918, L. fluminensis Ohaus, 1918, L. iridipennis Ohaus, 1917, L. lucipetens Ohaus, 1931, L. occipitalis Ohaus, 1931, L. pallefactus Ohaus, 1924, L. paulista Ohaus, 1917, L. punctulatus Blanchard, 1851, L. suturalis Laporte, 1840, L. trochantericus Ohaus, 1917, L. verticalis Ohaus, 1924, Macraspis cincta (Drury, 1872), Paranomala tricostulata (Ohaus, 1897), P. violacea (Burmeister, 1844), Pseudodorysthetus calcaratus (Spinola, 1835) e Trizogeniates planipennis Ohaus, 1917. Foi feito o primeiro registro de Pelidnota unicolor unicolor (Drury, 1778) para a Bahia. Foram identificadas 14 espécies, que serão descritas em trabalhos posteriores: dez de Leucothyreus MacLeay, 1819, duas de Lobogeniates Ohaus, 1917 e uma de Byrsopolis Burmeister, 1844 e Pelidnota MacLeay, 1819. A tribo Rutelini apresenta a maior riqueza com 16 gêneros e 49 espécies. Os resultados aqui apresentados têm importantes informações para o conhecimento de Rutelinae, no estado da Bahia e no Brasil, e servirão de base para a realização de futuras pesquisas com o grupo.

Three new species of Pelidnota MacLeay (Coleoptera, Scarabaeidae, Rutelinae) and new distributional records from northeast Brazil

Abstract Three new species of Pelidnota MacLeay, 1819 are described from Brazil, P. beckeri sp. nov., P. nordestina sp. nov., and P. pernambucana sp. nov. The diagnostic characters of the new species are presented, and they are included in the previously published key to Pelidnota. Illustrations of the male genitalia and photographs of males and females of the new species are also provided. It is reported the first record of the genus for the Brazilian Caatinga (tropical seasonal forest). New records of four species and two subspecies of Pelidnota are presented, all from Bahia state, northeastern Brazil.
