A new species of Mesochila Rivalier, 1969 (Coleoptera: Cicindelidae) from the Brazilian Caatinga.

Here we describe a new species, Mesochila (Mesochila) moraveci sp. nov. from Piauí, Brazil, the second of the genus to occur in the Caatinga. This new species shares the shape of the aedeagus and the structure of the internal sac with M. (M.) brevipennis, M. (M.) drechseli and M. (M.) prepusula, but can be easily distinguished by the presence of a whitish elytral humeral band. We provide a key to M. (M.) brevipennis species-complex as well as illustrations for the diagnostic characters for these species.

Three new species of Hylotribus Jekel, 1860 from Brazil, with new records and discussion of species relationships and wing variation within the genus (Coleoptera: Anthribidae).

Recent efforts with Malaise trap sampling in Serra dos Órgãos and Itatiaia, in Brazil, allowed us to identify and describe three new species from the first locality: Hylotribus humeralis sp. nov., H. nanico sp. nov. and H. queirozi sp. nov. New records of H. plaumanni Queiroz Mermudes, 2014 for both localities and H. sublimis Queiroz Mermudes, 2014 for the latter are also presented. We also describe morphological variability including aptery and microptery, and male genitalia, for H. plaumanni. We produce a new key to the species and discuss the species relationships and wing variation for the genus.

A new tropical montane firefly genus and species, active during winter and endemic to the southeastern Atlantic Rainforest (Coleoptera: Lampyridae).

Here we describe Araucariocladus hiems gen. et sp. nov. (Lampyridae: Amydetinae), a firefly species endemic to high montane forests, and occurring during June, a relatively cool and dry month in the Southeastern Atlantic Rainforest of Brazil. We tentatively place it in Psilocladina McDermott, and discuss the limitations of its classification. We also provide illustrations of key structural features of the new taxa and discuss its affinities.

Larval structure of Passalus gravelyi and sexual dimorphism in Passalid larvae.

The adults and larvae of Passalidae are subsocial insects commonly found in tropical forests, living in decaying wood gallery systems constructed by adults. Currently, few repots on the larvae of Neotropical Passalidae have been published and information is scarce. In this study, the Passalus (Pertinax) gravelyi Moreira, 1922 larvae is described for the first time, based on ten larval specimens 1 (1° instar), 4 (2° instar), and 5 (3° instar) associated with three adults collected from a single colony at the Parque Nacional do Itatiaia (Itatiaia, Rio de Janeiro, Brazil). The description was carried out based on electronic and digital photographs of diagnostic structures, with some details on the systematic of the species. The larvae of Passalus gravelyi has the general setal 'Pertinax' pattern and differed from others by 16 to 18 setae on the anal ring, the other larvae data from Brazilian species show the anal ring with 10 to 12 setae. A discussion on the presence of sexual dimorphism in 62 species of two and three instars of Passalidae larvae is provided for the first time. Besides, a description of the terminal ampulla present as a cuticular structure found in the medial-ventral area of the 9th abdominal sternite in males is also given. The terminal ampulla was only observed in the Passalidae male larvae and was not visible in female larvae. The terminal ampulla are acknowledged now in males of 64 passalid species, that are taxonomically distributed in world tropical forests, at the Oriental and Australian subfamily Aulacocyclinae (Aulacocyclini & Ceracupini) and the cosmotropical subfamily Passalinae (Solenocyclini, Macrolinini, Passalini, & Proculini).

Passalidae son insectos subsociales, los adultos y larvas son comunes en bosques tropicales, viven dentro de troncos podridos en un sistema de galerías construido por los adultos. A la fecha, pocos estudios han sido publicados sobre larvas de Passalidae neotropicales. En el presente trabajo, se describe por primera vez la larva de Passalus (Pertinax) gravelyiMoreira, 1922, con base en 10 especímenes: uno de primer estadio, cuatro de segundo estadio y cinco de tercer estadio, asociados con tres adultos de un grupo familiar recolectado en el Parque Nacional de Itatiaia (Río de Janeiro, Brasil). La descripción esta fundamentada en microfotografías electrónicas y digitales de los caracteres diagnósticos que muestran detalles sobre la sistemática de la especie. La larva de Passalus gravelyimuestra el patrón setal general de 'Pertinax' y difiere de otras larvas del sub&género Pertinaxpor tener el anillo anal con 16 a 18 setas, las seis especies de larvas descritas del Brasil tienen en el anillo anal con 10 a 12 setas. Por primera vez se discute la presencia de dimorfismo sexual en larvas de 62 especies de Passalidae, describiendo el ampulla terminalpresente en el macho y localizada en el área cuticular media ventral del noveno esternito abdominal. El ampulla terminales visible ventralmente solo en la larva macho y no es visible en la larva hembra; esta estructura cuticular es común en el macho sobre el noveno esternito abdominal del segundo y tercer estadio larval y no está presente en la larva de primer estadio. El ampulla terminales conocida en 62 especies agrupadas taxonómicamente en la subfamilia oriental y australiana Aulacocyclinae (Aulacocyclini e Ceracupini) y en la subfamilia cosmotropical Passalinae (Solenocyclini, Macrolinini, Passalini, e Proculini).
