First survey of the Passalidae (Coleoptera, Scarabaeoidea) species from Reserva Ecológica de Guapiaçu (REGUA), Cachoeiras de Macacu, RJ, Brazil

We present the details of a survey with species of passalid conducted in the Reserva Ecológica de Guapiaçu (Cachoeiras de Macacu, Rio de Janeiro State) together with illustrations for each species and an identification key. The study includes material collected between May 2010 and October 2013. We identified 11 species in three genera and two tribes (Passalini and Proculini). Passalini comprised two genera, Passalus with six species, and Spasalus with one species, representing 71.42% of all the species encountered. Proculini was represented by only one genus Veturius, with four species, representing 28.57% of the species surveyed. Nine species were recorded for the first time from Cachoeiras de Macacu municipality.

Passalidae (Coleoptera: Scarabaeoidea) from Ilha Grande (Angra dos Reis, RJ) with new diagnosis and distributional records in Brazil

A survey of the Passalidae species recorded to the Ilha Grande (Angra dos Reis, Rio de Janeiro, Brazil) is presented, with illustrations for each species and a key with diagnosis for genera. Passalus (P.) denticollis Kaup, 1869 and Veturius (V.) transversus Dalman, 1817 was the relative abundance most dominate, representing almost 50% of relative abundance of species in each genus respectively. The study included material collected between January and December of 2008 and it results in 13 species included in four genera and two tribes (Passalini and Proculini). Passalini comprised ten species (Passalus, Spasalus and Paxillus), representing 71.42% of all species. Proculini with three species belong only Veturius, representing 28.57%. Among the 13 species, 12 are registered by first time from Ilha Grande. Veturius (Veturius) sinuatus was the unique species with distribution confirmed and Spasalus cristinae known only São Paulo had the distribution extended to Rio de Janeiro

Phylogeny, infrageneric classification and historical biogeography of Mesochila Rivalier, 1969 (Coleoptera: Cicindelidae), with the performance of different phylogenetic inferences using morphological data compared

In this study, we aim to understand the boundaries and the species evolutionary relationships in Mesochila, which includes 20 species arranged into three subgenera. We also conducted a biogeographic analysis that allowed us to identify the major events that shaped the currently disjunct distribution of the group. Our analyses were performed employing four major phylogenetic algorithms: equal and implied weight parsimony, maximum likelihood and Bayesian inference. Phylogenetic analyses, including 25 taxa (all 20 species in the genus plus five outgroups) and 37 characters, indicated that Mesochila is a monophyletic group composed of four strongly supported lineages, although no consensus was attained regarding relationships between lineages. Bayesian inference resulted in the less resolved topology, whereas implied weight parsimony yielded the most different tree when using a low k value (1). We present a new infrageneric classification for the group with the description of Mesochila (Neomesochila) subgen. nov. to accommodate M. (N.) brevipennis, M. (N.) drechseli, M. (N.) moraveci, and M. (N.) prepusula. Furthermore, we transfer M. (M.) distincta from M. (Eumesochila) back to M. (Mesochila). The biogeographical analysis suggested a South American origin for the group, in Chacoan/Paraná dominions (Atlantic rainforest/Cerrado biomes), with subsequent dispersions to Central America and Amazonia

Redescrição e transferência do gênero Fregolia Gounelle, 1911 para Callidiopini (Coleoptera, Cerambycidae)

<abstract language="eng">Redescription and transference of the genus Fregolia Gounelle, 1911 to Callidiopini (Coleoptera, Cerambycidae). The genus Fregolia is transferred from Cleomenini Lacordaire, 1869 to Callidiopini Lacordaire, 1869. The genus and its type species, Fregolia listropteroides Gounelle, 1911, the only known species to the genus, are redescribed including characters of the mouth pieces, endosternites, wing venation, and male and female terminalia
