A new genus and species of Agriotina Laporte, 1840(Coleoptera: Elateridae: Agriotini) from Colombia

Here, we describe and illustrate a new genus of Elateridae from Cundinamarca, Colombia, Raphaellus Zurita-García, Morales-Perdomo & Martínez-Luque, n. gen., to accommodate the new species R. deusminutosi Zurita-García, Morales-Perdomo & Martínez-Luque n. sp. The genus Raphaellus belongs to the subtribe Agriotina (Agriotini). A key to distinguish the genera of the New World subtribe Agriotina and taxonomic notes on Agriotini are presented.

Life cycle and description of the immature stages of a terrestrial firefly endemic to Mexico: Photinusextensus Gorham (Coleoptera, Lampyridae)

The life cycle, morphology, and bionomy of Photinusextensus Gorham, 1881, an endemic species of Mexico, are described. Redescriptions of adults (male and female) are also presented. Larvae were reared to the adult stage from eggs laid by females collected at the El Pedregal de San Ángel Ecological Reserve, south of Mexico City. The activity period of adults of P.extensus begins at the end of July and finishes by the end of August. Females lay between 3 and 198 eggs. Larvae hatch from the eggs after a period of 11 to 71 days, undergo 6 larval instars and a pupal stage in an annual cycle. Morphological characters of the sixth larval instar of P.extensus are compared with those of several other genera assigned to the tribe Photinini. Knowledge of the natural history of firefly larvae is relevant since most species do not feed as adults and therefore depend on resources acquired during the larval stage.

First report of the genus Cladotoma Westwood, 1837 (Coleoptera, Ptilodactylidae, Cladotominae) in Mexico

The genus Cladotoma Westwood, 1837 (Ptilodactylidae) has seven species distributed in Argentina, Costa Rica, French Guiana, and Panama. Cladotoma ovalis Westwood, 1837 is record for the first time in Mexico, in the states of Jalisco and Chiapas. Illustrations, distribution map and a diagnosis for the genus and for C. ovalis are herein presented. A checklist of Ptilodactylidae species in Mexico and an identification key for Mexican genera is also presented.

A checklist of the Coleoptera (Insecta) from Morelos, Mexico

Data from the literature and from specimens preserved at the Colección Nacional de Insectos (CNIN) Instituto de Biología, UNAM were used to compile a checklist of the fauna of Coleoptera of the state of Morelos, México. A sum of 70 families, 167 subfamilies, 361 tribes, 1,022 genera, and 2,606 species are recorded; from this 24 species are new records for Morelos. The State of Morelos ranks fourth in Coleoptera species richness for Mexico, following Veracruz (3,176 spp.), Oaxaca (2,148 spp.) and Chiapas (1,734 spp.). The checklist presented here provides a summary that can serve as a basis for future progress in the knowledge of Mexican Coleoptera.
