Coilodes Westwood, 1846 is a Neotropical genus of Hybosorinae. Despite being a morphologically homogeneous genus, it presents a great deal of intraspecific variation, especially with reference to the colour of integuments. This makes identification of species even more difficult, since the majority of original descriptions present the colour as the main diagnostic character. To solve this problem, the first taxonomic revision of Coilodes is presented. The genus now comprises 13 species. Redescriptions of C. castaneus Westwood, 1846, C. fumipennis Arrow, 1909, C. humeralis (Mannerheim, 1829), C. niger (Mannerheim, 1829), C. ovalis Robinson, 1948, C. parvulus Westwood, 1846, and C. punctipennis Arrow, 1909 are presented. Coilodes niger (Mannerheim, 1829) has its status revalidated and three new synonyms are proposed: C. gibbus (Perty, 1830) and C. chilensis Westwood, 1846 with C. humeralis, and C. nigripennis Arrow, 1903 with C. castaneus. Biological and geographical distribution data are expanded. Lectotypes are designated for C. humeralis and C. niger. Six new species are described: C. bezerrai Basílio & Vaz-de-Mello sp. nov., C. edeiltae Basílio & Vaz-de-Mello sp. nov., C. lunae Basílio & Vaz-de-Mello sp. nov., C. mayae Basílio & Vaz-de-Mello sp. nov., C. ravii Basílio & Vaz-de-Mello sp. nov., and C. skelleyi Basílio & Vaz-de-Mello sp. nov. An identification key for the males of the species is presented.
Differential diagnoses, updates on distribution ranges, and an illustrated identification key are given for all species of Agamopus. The first record for A. castaneus from Brazil is given. Type specimens of all valid species-group names are studied and illustrated. Notes on the natural history of Agamopus species, as well as brief phylogenetic comments, are presented. The new species Agamopus joker sp. nov. is described based on a male from Paraná, southern Brazil. Lectotypes are designated for Canthon unguicularis Harold, 1883 and Agamopus lampros Bates, 1887. We also propose the transfer of Agamopus convexus Balthasar, 1965 to the Ateuchus ovalis species group (Ateuchus convexus comb. nov.) based on morphological features of the protibiae, clypeal teeth, and the posterior margin of the pronotum and pygidium.
An unusual eye malformation observed in Trichiotinus rufobrunneus (Casey) (Coleoptera: Scarabaeidae: Cetoniinae: Trichiini), is described and illustrated. The functionality of the ectopic compound eye is discussed. According to label data, larval association with oak rotten log habitats is reported.
Clé de détermination des Coléoptères Lucanides et Scarabéides de Vendée et de l’Ouest de la France
(2002)
It is an identification key of species of beetles called Lucanoideas and Scarabaeoideas already observed in Vendée and in Western France or likely to be found there some day or other. 160 species have been described, often illustrated with maps of their habitats in France.
This is a preliminary inventory of Coleoptera, Lucanoidea, Scarabaeoidea found up to now in Vendée (France). The supposed status of each of these species (frequency and distribution …) is mentioned within the scope of our present knowledge.
