Manuscripts considered for publication include, but are not limited to, systematic or taxonomic studies, revisions, nomenclatural changes, faunal studies, book reviews, phylogenetic analyses, biological or behavioral studies, etc. Insecta Mundi is widely distributed, and referenced or abstracted by several sources including the Zoological Record, CAB Abstracts, etc.

specimens recently collected from Tabasco. Historical records from the literature are reviewed. A modification to the
identification key of the species of Tomarus in Mexico is provided.

The new species is compared with Cotinis barthelemyi (Gory & Percheron) from Colombia. The Neotropical distribution of Cotinis is expanded to Venezuela. A revised key to the species of Cotinis is provided in both English and Spanish.

Colombia. The new species is compared with Tomarus laevicollis (Bates, 1888) from Central America. An identification key is also provided to the species occurring in the country.

This is not intended to impose a theory or philosophy, but, rather, to be a reflection on the way in which once can encourage and maintain relevant research and conservation of biological diversity in the country. It is essential to know the biodiversity of a region in order to implement conservation programs.

Topics considered for publication include systematics, taxonomy, nomenclature, checklists, faunal works, and natural history. Insecta Mundi will not consider works in the applied sciences (i.e. medical entomology, pest control research, etc.), and no longer publishes book reviews or editorials. Insecta Mundi publishes original research or discoveries in an inexpensive and timely manner, distributing them free via open access on the internet on the date of publication. Insecta Mundi is referenced or abstracted by several sources including the Zoological Record, CAB Abstracts, etc. Insecta Mundi is published irregularly throughout the year, with completed manuscripts assigned an individual number. Manuscripts must be peer reviewed prior to submission, after which they are reviewed by the editorial board to ensure quality. One author of each submitted manuscript must be a current member of the Center for Systematic Entomology.

An updated and annotated checklist of the Oryctini of the Neotropical and Nearctic realms is included. This now includes 14 genera, 133 extant species, and two extinct species. Tehuacania porioni Dechambre, 2009 (Oryctini) is reduced to synonymy with Barutus hartmanni Ratcliffe, 2003 (Pentodontini).
An illustrated key to identify the adults at the generic level of Dynastinae known from Colombia ... more An illustrated key to identify the adults at the generic level of Dynastinae known from Colombia is provided. A synopsis for each genus is given with updated information on the diversity and distribution of species in Colombia and worldwide. A peer-reviewed open-access journal Brachysiderus Waterhouse 1881: 409.

Para cada método se indican las ventajas y desventajas y se sugiere una estandarización de colecta para optimizar la investigación en el dosel. Se proporciona una clave para la elección de un método adecuado de colecta para investigadores interesados en el estudio de artrópodos de dosel en los bosques de niebla.
