This note reports on placement of Ateuchus benitojuarezi Moctezuma, Sanchez-Huerta, & Halffter, 2018 (Coleoptera: Scarabaeidae: Scarabaeinae: Ateuchini) as a junior synonym of Ateuchus guatemalensis (Bates, 1887) new synonymy . Ateuchus guatemalensis was originally described from Guatemala and is now known from Chiapas (Mexico), Honduras, and Nicaragua (Kohlmann & Vaz-de-Mello 2018). With the new synonym discussion below, A. guatemalensis also occurs in the Chimalapas region in Oaxaca (Mexico), ...

Abstract An analysis based on fossilized animal tracks, oral tradition, archaeological findings, and the distribution and biology of dung beetles is presented to suggest that Copris subpunctatus Gillet (Coleoptera: Scarabaeidae) probably fed on bison dung and switched to cow dung after cattle were introduced by the Spanish colonizing effort. This transition probably took place before the bison apparently became extinguished in Costa Rica at the end of 19th or beginning of the 20th century.

In this paper we describe Canthidium quercetorum new species (Coleoptera: Scarabaeidae: Scarabaeinae), a species that inhabits dry oak forest in the Mexican state of Oaxaca, between 2100 and 2300 m above sea level. Photographs and an illustration of the habitus and a distribution map are provided. The unusual distribution and ecology of this species are discussed. An updated key for the genus in Mexico and the United States of America is also presented.

Abstract The first Ateuchus Weber (Scarabaeinae) species, A. tuza sp. nov., from a rodent burrow from North America is described. Diagnostic characters are presented; photographs of an adult male and illustrations of male genitalia are included. A key for all known Mexican Ateuchus Weber species is provided. Ateuchus hornai (Balthasar) is revalidated. New distribution records from Mexico and Central America are reported.

Abstract Biological monitoring using aquatic organisms is becoming a very much used tool for assessing river health. Its use began at the end of the last century in Latin America. This chapter presents the successful use of this tool in Argentina, Chile, and Costa Rica, in order to measure agricultural impacts on river water quality. Apple orchards and eucalyptus and banana plantations are presented as study models. The methodologies used for these analyses represent a simple, quick, efficient, ...

Abstract An integrated multidisciplinary approach to assess the impact of pesticide management practices in selected microcatchments is presented in this guideline. It combines monitoring and modeling approaches, using analytical and biomonitoring methodologies to target high-impact rating pesticides in surface water and sediments from upstream and downstream “collection” points. This is referred to as a “black-box” strategy. This creates a new role for the analytical laboratory that has to appl...
