TL;DR: Parque Bicentenario in the Área Natural Protegida El Espino-Bosque Los Pericos, considered the “last green lung of San Salvador”, is the most important forested area in central El Salvador and provides the first inventory of scarab beetles (Scarabaeidae) of the park.
Abstract: Abstract Parque Bicentenario in the Área Natural Protegida El Espino-Bosque Los Pericos, considered the “last green lung of San Salvador”, is the most important forested area in central El Salvador. We performed a survey to provide the first inventory of scarab beetles (Scarabaeidae) of the park. Collections were conducted monthly for one year (August 2018–July 2019) by using baited pitfall, aerial, and ultraviolet light traps. Four subfamilies, nine tribes, 14 genera, 20 species (8% of the total richness of the family in El Salvador), and 1,584 individuals were captured. The most abundantly collected species in the park were the scarabaeines Onthophagus batesi Howden and Cartwright, Onthophagus belorhinus (Bates), Dichotomius centralis (Harold), Coprophanaeus corythus (Harold), Dichotomius yucatanus (Bates), and Coprophanaeus boucardi (Nevinson).

TL;DR: In this paper , the suitability of Scarabaeidae beetle functional groups as ecological indicators to detect differences in the conservation status of two protected areas in El Salvador was evaluated and the results suggest the possibility of using this approach to monitor protected areas, to estimate the forest conservation status, and to evaluate the conservation strategies implemented to date.
Abstract: Summary Planning, implementing, and systematic revision of conservation policies are necessary to protect the biodiversity of a territory. This is critical in countries heavily impacted by anthropogenic activities, like El Salvador, where conserving biodiversity remnants must be a priority. Monitoring indicator groups represents a feasible option to review the status of biodiversity and the processes taking place in the country's conservation areas. We evaluated the suitability of Scarabaeidae beetle functional groups as ecological indicators to detect differences in the conservation status of two protected areas in El Salvador. We conducted monthly sampling for one year at each site, using pitfall, aerial, and UV-light traps to capture beetles. We detected differences in species richness, abundance, species composition, and turnover between the two areas. The results suggest the possibility of using this approach to monitor protected areas, to estimate the forest conservation status, and to evaluate the conservation strategies implemented to date. For the future, it is essential to determine if this is possible by replicating studies throughout the territory using standardized methodologies to obtain comparable results. The cost–benefit ratio of using a single indicator group is key in countries like El Salvador, where the economic aspect is a limiting factor for biological prospecting.

Abstract: Abstract. Patterns of description of new species of beetles from Mexico between 2000-2020 were analyzed. We based our study on the Zoological Record of Web of Science™. We found 1,867 species in 61 families described in 759 papers published in scientific journals from all over the world. Scarabaeidae is the family with the most species described (352) in the last two decades, followed by Staphylinidae (198), Curculionidae (196), Cleridae (176), and Cerambycidae (175). Most species of Mexican beetle were described in Zootaxa, Coleopterists Bulletin, Insecta Mundi, Dugesiana, and Zookeys. We also provided comments on issues to consider when Zoological Record is used for analysis such as in this study.

TL;DR: A new species of Coleoptera: Rutelinae beetle, Lagochile occidentalis, collected with aereal fruit traps from an ecotone zone with oak, pine, tropical subdeciduous, and cloud forest in Jalisco is described in this paper .
Abstract: Resumen. Se describe una nueva especie de Coleoptera: Rutelinae, Lagochile occidentalis, capturada con carpotrampas aéreas de una zona de ecotono con elementos de bosque de encino, bosque de pino, bosque mesófilo, de montaña y bosque tropical subcaducifolio en Jalisco. Se proveen ilustraciones de los caracteres distintivos de las especies del género presentes en México, así como de la variación cromática dorsal. Abstract. A new species of Coleoptera: Rutelinae beetle, Lagochile occidentalis, collected with aereal fruit traps from an ecotone zone with oak, pine, tropical subdeciduous, and cloud forest in Jalisco is described. Diagnostic characters are illustrated for the species, and its dorsal chromatic variation.
TL;DR: In this article , the authors describe the patterns of richness and abundance along an elevational gradient, complemented with an annotated checklist of necrophagous beetle species (Scarabaeidae, Trogidae, Geotrupidae, and Silphidae) collected in Cerro de García, Jalisco.
Abstract: Abstract The present work describes the patterns of richness and abundance along an elevational gradient, complemented with an annotated checklist of necrophagous beetle species (Scarabaeidae, Trogidae, Geotrupidae, and Silphidae) collected in Cerro de García, Jalisco. The site is located southwest of Lake Chapala and in the western region of the Trans-Mexican Volcanic Belt. Specimens were collected each month during one year of sampling. Seven sites were surveyed with elevations ranging from 1,600 to 2,700 m. At each site, two carrion traps baited with squid were used and additional specimens were collected directly from cow dung during July. A total of 4,320 specimens were collected, belonging to 26 species within four families. Silphidae were the most abundant beetle family, comprising 64% of the total beetle abundance. In the superfamily Scarabaeoidea, Scarabaeidae were the most abundant at 31% of the total abundance and also the most diverse. Geotrupidae and Trogidae represented 5% of the total abundance. The results show that richness and diversity indices decrease as the elevation increases. However, abundance values were highest at an intermediate elevation of 2,000 m. The diversity of richness and abundance along the elevational gradient showed greatest spatial heterogeneity in the distribution of dung beetle species at 2,000 m where sites with species with affinities to tropical and high mountain environments overlapped.
TL;DR: The first report in Mexico of pinna lesions, associated mites, and histopathological findings for two species of free-living bats: the Jamaican fruit-eating bat (Artibeus jamaicensis) and the Honduran yellow-shouldered bat (Sturnira hondurensis) as discussed by the authors .
Abstract: Abstract. Lesions of the pinnae of captive bats are common, but there are few reports for free-living bats. In those reports, causal agents of the lesions were attributed to mites, fungus, or a combination of factors, but specific information regarding pinna lesions is generally lacking. This is the first report in Mexico of pinna lesions, associated mites, and histopathological findings for 2 species of free-living bats: the Jamaican fruit-eating bat (Artibeus jamaicensis) and the Honduran yellow-shouldered bat (Sturnira hondurensis). Resumen. Reportes de lesiones en las pinas de murciélagos en cautiverio son comunes, pero hay pocos para murciélagos de vida libre. Aunque se han atribuido a agentes causales como ácaros, hongos o una combinación de factores, información específica sobre las causas que afectan las pinas es escasa. Este es el primer reporte en México de lesiones en pinas, ácaros asociados y hallazgos histopatológicos, para el murciélago frugívoro de Jamaica (Artibeus jamaicensis) y el murciélago de hombros amarillos de Honduras (Sturnira hondurensis) en vida libre.
TL;DR: In this paper , the diversity of beetles collected with flight interception traps at Parque Estatal Bosque de Arce, Talpa de Allende, Jalisco, Mexico was studied.
Abstract: Abstract. Diversity of beetles collected with flight interception traps at Parque Estatal Bosque de Arce, Talpa de Allende, Jalisco, Mexico was studied. Sampling was done during dry and wet seasons. In total, 3,857 individuals of 29 families, 214 morphospecies, and 73 genera were collected. Two sites, one with great diversity in the spring and the other with greatest diversity in winter, were sampled. Most abundance and species richness at both sites were in summer. Complementarity values near 1 and low similarity of the beetle assemblage between seasons and sites, described different composition between sites and increased diversity at the landscape level in the forest. Four beetle species and two new genera records were recorded for the State of Jalisco.
