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.
The life cycle, morphology, and bionomy of Photinus extensus 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.
Se presentan nuevos registros de 𝑃ℎ𝑜𝑡𝑖𝑛𝑢𝑠 𝑝𝑎𝑙𝑎𝑐𝑖𝑜𝑠𝑖 (Zaragoza-Caballero, 2012) para los estados de: Hidalgo, Ciudad de México, México y Puebla, así como notas sobre su conducta y simpatría con otras especies de luciérnagas de hábitos nocturnos. Se presenta un mapa de distribución y una lámina comparativa de esta especie con 𝑃ℎ𝑜𝑡𝑖𝑛𝑢𝑠 𝑒𝑥𝑡𝑒𝑛𝑠𝑢𝑠 Gorham, 1881.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
