New Records of Termite Hosts for Two Species of Hoplopyga, with Notes on the Life Cycle of Hoplopyga brasiliensis (Coleoptera: Scarabaeidae: Cetoniinae)

ABSTRACT We provide the first report of larvae of Hoplopyga brasiliensis (Gory and Percheron) and H. singuhris (Gory and Percheron) (Coleoptera: Scarabaeidae: Cetoniinae) in nests of Cornitermes cumulans (Kollar) (Isoptera: Termitidae: Syntermitinae) and Dwersitermes diversimiles (Silvestri) (Isoptera: Termitidae: Nasutitermitinae), respectively. We also provide new information on the life cycle of H. brasiliensis and the feeding behavior of adults of H. singularis. In total, 44 larvae of H. brasiliensis were found in a single nest of C. cumulans in apastureland in Coimbra, state of Minas Gerais, Brazil. Larvae of H. singularis were found under nests of D. diversimites at two urban parks in the state of Parana, Brazil. ≈15 larvae of H. singulis in different stages of development and some opened pupal cells were found in some nests of D. diversimiles. We increase the number of known termitophilous Hoplopyga species to three and discuss such relationships in light of published data and new information provided here.

New record of predatory ladybird beetle (Coleoptera, Coccinellidae) feeding on extrafloral nectaries

New record of predatory ladybird beetle (Coleoptera, Coccinellidae) feeding on extrafloral nectaries. Feeding by Exoplectra miniata (Germar) on extrafloral nectaries of Inga edulis Mart. was observed in Nova Friburgo, Rio de Janeiro, Brazil. This is the first record of this behavior for Exoplectrini.

Histerídeos (Staphyliniformia: Coleoptera: Histeridae) dos Campos Gerais, Paraná, Brasil

Histeridae is a group of beetles with diverse morphology known as generalist predators and which occurs in a wide variety of habitats. The objective of this paper was to present the first list of Histeridae from the Campos Gerais region (Parques Estaduais de Vila Velha, do Cerrado, e do Cânion Guartela) and provide information about species from protected areas in the state of Parana. Also were provided appropriate collecting methods for the group. The Histeridae from Campos Gerais are represented by 29 species belonging to eight genera: Haeteriinae sp. (1 sp.), Coelister Bickhardt, 1917 (1 sp.), Epierus Erichson, 1834 (1 sp.), Euspilotus Lewis, 1907 (6 spp.), Hister Linnaeus, 1758 (2 spp.), Omalodes Dejean, 1833 (3 spp.), OperclipygusMarseul, 1870 (6 spp.) and Phelister Marseul, 1854 (9 spp.). Two genera (Coelister and Epierus) and four species (Coelister sp., Phelister brevistrius Marseul, 1854, Phelister panamensisLeConte, 1859 and Phelister pumilus (Erichson, 1834)) were recorded for the first time for the state of Parana. Five genera (Coelister, Epierus, Euspilotus, Hister and Phelister) and five species (Coelister sp., Omalodes laceratus Marseul, 1853, Phelister brevistrius, Phelister panamensisLeConte, 1859 and Phelister pumilus (Erichson, 1834)) were recorded for the first time for Campos Gerais. The fauna of Histeridae is diverse when compared with surveys conducted in other floristic conditions. However, the majority of species do not demonstrate a selection for open grass field areas. Considering the habitats loss of Campos Gerais it is important to increase the faunistic surveys with appropriate methodology and regional lists of Coleoptera in order to know the biodiversity.

First Report of Bolbites Harold (Scarabaeidae: Scarabaeinae: Phanaeini) in Brazil

The monobasic genus Bolbites Harold was described based on specimens from Montevideo, Uruguay (Harold 1868). Later, Bolbites onitoidesHarold was reported from Paraná (Entre Ríos) and Río Negro in Argentina (Burmeister 1874), from Bolivia with no further data and (probablywrongly)Chile (d’Olsoufieff 1824), and from Paraguay (Martínez 1959). Further published data cite this species from Buenos Aires, La Pampa, Córdoba, San Luís, Catamarca, La Rioja, Santiago del Estero, Salta, Tucumán, Chaco, Formosa, Santa Fe and Corrientes (Martínez 1959, 1989), and Santa Cruz (Abapó) in Bolivia (Kirk 1992). The purpose of this note is to report for the first time the presence ofB. onitoides inBrazil. Four males and two females were collected in Porto Murtinho, Mato Grosso do Sul in January 2008 by F. B. Fernandes and deposited in the Seção de Entomologia da Coleção Zoológica da Universidade Federal de Mato Grosso (CEUFMT) and Departamento de Zoologia da Universidade Federal do Paraná (DZUP). These specimens constitute a new country record forB. onitoides. PortoMurtinho is located on the Paraguay River separating Brazil and Paraguay. We have also seen six specimens (CEUFMT) from Pozo Colorado, Presidente Hayes (Paraguay), about 250 km in a straight westerly line from Porto Murtinho, where the climate is much drier. The reported localities in Bolivia (Abapó) and Argentina (Paraná) closest to Porto Murtinho are, respectively, about 750 km and 600 km distant. Martínez (1959) mentions the existence of two different “forms” ofB. onitoides, which he later refers to as “subspecies” (Martínez 1989), an undescribed one being restricted to drier areas of Argentina. Specimens from Brazil are red with greenish reflections on both the pronotum and the elytra. Similar coloration of specimens from Uruguay (CEUFMT and DZUP), Paraguay (CEUFMT), and Buenos Aires (CEUFMT)were observed.Another color pattern observed has a red pronotum and blue elytra (Paraguay, Trans-Chaco, doubtful data; Argentina, BuenosAires and Santiago del Estero). Yet another pattern, dark blue green, characterizes specimens from Pozo Colorado and Salta (CEUFMT and DZUP) and TransChaco, Paraguay (doubtful data, CEUFMT). A careful study of large series with good collecting data is necessary to test Martínez’ hypothesis on the existence of two closely related forms in this genus. Finally, with this report for Bolbites, and the recent report by Gillett et al. (2009) for Megatharsis Waterhouse, all phanaeine genera except Oruscatus Bates are now known from Brazil. We thank F. B. Fernandes who made Brazilian specimens available for study, and an anonymous reviewer for constructive comments.

Surutu jelineki Endrödi (Cyclocephalini), a New Junior Synonym of Platyphileurus felscheanus Ohaus (Phileurini) (Coleoptera: Scarabaeidae: Dynastinae)

The monotypic genus Platyphileurus Ohaus (Phileurini), with its only species Platyphileurus felscheanus Ohaus, was described by Ohaus (1910) based on a supposed female in his collection and an unstated number of other specimens in C. Felsche’s collection from Santa Catarina, Brazil. Later, Endrödi (1975), reviewing the genus Surutu Martínez (Cyclocephalini), described Surutu jelineki Endrödi based on two supposed females, one from Rio de Janeiro and another from “Brasilien”. When Endrödi (1977) included Platyphileurus in his key to the American genera of Phileurini, he described both the male and female of P. felscheanus (he considered a female to be the “holotype”, probably the one from Ohaus’ collection), illustrated the male genitalia, and cited six examined specimens, all with localities from Santa Catarina, except for one doubtful record from “Isle de Prince”. We examined the specimen Endrödi (1977) considered as the holotype of P. felscheanus, which was loaned to theMuseu de Zoologia daUniversidade de São Paulo from the Zoologische Museum der Humboldt-Universität (Berlin). We compared it with the original descriptions of S.jelineki and P. felscheanus, and we conclude that these two taxa are conspecific. Accordingly, we here designate Surutu jelineki as a new junior synonym under Platyphileurus felscheanus. It is surprising thatEndrödi (1975, 1977) examined females from both Santa Catarina and Rio de Janeiro and placed those specimens in different genera in different tribes, thus we surmise that he was then so involved in the herculean

Discovery of a Third Stag Beetle Genus in the Amazonian Region, with Description of a New Species of Psilodon Perty (Coleoptera: Lucanidae: Syndesinae: Syndesini)

Abstract Psilodon buhrnheimi Grossi and Aguiar, new species, is described from Amazonas, Brazil, becoming the third genus of Lucanidae found in this region. The new species is illustrated and compared with the other two Brazilian species of Psilodon Perty from Piauí and Bahia, both in northeastern Brazil. A distributional map of the known species of Lucanidae of the Amazonian region and a key to the stag beetle genera in the region are also presented, as well as biological data for Psilodon and a key to the known species of the genus. The male genitalia is described and illustrated for the first time for a Brazilian species, and comments are made about the correct identity of Psilodon schuberti Perty, 1830.

Revision of the rhinoceros beetle genus Oryctophileurus Kolbe with description of a new species, the male of O. varicosus Prell, and notes on biogeography (Scarabaeoidea, Dynastinae, Phileurini)

Abstract The genus Oryctophileurus is reviewed and its validity is supported by a combination of the following apomorphic characters: a single cephalic horn with lateral carina, pronotal cavity with ocellate punctures and two teeth or tubercles close behind the anterior pronotal margin. The male of Oryctophileurus varicosus Prell, 1934, is described for the first time. A new species, Oryctophileurus guerrai Perger & Grossi sp. n., from subhumid Tucuman-Bolivian forest in the Southern Bolivian Andes is described. The new species is distinguished from its closest relative, O. armicollis Prell, 1911, by a narrower distance between the inner teeth of the dorsal pronotal protuberances and a reduced area of weakly developed ocellate punctures above the posterolateral pronotal margin. The occurrence of Oryctophileurus species in areas of endemism along the eastern slope of the tropical Andes suggests that these populations represent biogeographic “relicts”, and the discovery of Oryctophileurus guerrai sp. n. in the southern Bolivian Andes suggests that this area is underrated with respect to insect diversity and endemism.

A new species of Amblyodus Westwood, 1878 (Coleoptera, Melolonthidae, Dynastinae) from South America

Abstract A second species of Amblyodus Westwood, 1878, Amblyodus castroi sp. n., is described from the northern South America based on 12 specimens from Brazil and Peru (Amazonian subregion). The new species is here compared with the type species of the genus, Amblyodus taurus Westwood, 1878 and both species and their male genitalia are illustrated. Diagnostic characters for the genus are discussed, especially the metatibial teeth. A distribution map including the type species and the new species is provided. The genus Amblyodus is recorded for the first time from Peru and from Brazil states of Pará and Rondônia.

Revision of the genus Altitatiayus Weinreich(Coleoptera, Lucanidae, Lucaninae)

Revision of the genus Altitatiayus Weinreich (Coleoptera, Lucanidae, Lucaninae). The South American genus Altitatiayus Weinreich is revised and now includes six species, A. rotundatus (Boileau), A. ruficollis (Luderwaldt), A. godinhorum (Bomans & Arnaud), A. dulceae (Bomans & Arnaud), A. trifurcatus (Grossi & Racca-Filho) and A. koikei sp. nov. (Minas Gerais, Brazil). All species are described and illustrated. For the first time male and female genitalia are illustrated for five species and observations on the behavior of two species are included.

Report of Macraspis pseudochrysis Landin, 1956 (Coleoptera: Scarabaeidae: Rutelinae) on açai palms (Euterpe oleracea Mart.) in floodplains in the state of Amapá, Brazil

O acaizeiro [Euterpe oleracea] e uma palmeira da Amazonia Oriental encontrada com mais frequencia no estuario do Rio Amazonas. Recentemente, ribeirinhos em diferentes regioes do estado do Amapa observaram uma especie de coleoptero que ataca as inflorescencias de acaizeiros. Com o objetivo de identificar exemplares de Coleoptera em inflorescencias de E. oleracea no estado do Amapa, Brasil, foram coletados 13 individuos nas localidades de Abacate da Pedreira (dois exemplares), Ariri (seis)(ambas em Macapa) e no municipio de Mazagao (cinco), entre outubro de 2010 e fevereiro de 2011. Os coleopteros foram coletados diretamente nas inflorescencias de acaizeiros com auxilio de rede entomologica, conservados e enviados para identificacao. Todos os individuos pertencem a especie Macraspis pseudochrysis Landin, 1956 (Coleoptera: Scarabaeidae: Rutelinae). Este e o primeiro registro de ocorrencia de M. pseudochrysis em E. oleracea na regiao neotropical.
