A new species of Vaejovis is described for Michoacan, Mexico belonging to the nigrescens/nitidulus group, the less diverse group of species from the genus. This species has a preference for synanthropic environments and inhabits rock walls within the city limits. Additionally, the pictures of the hemispermatophore are presented and characters are named according to new terminology. This species is named honoring Dr. Gabriela Castaño Meneses for her great contributionsto arthropods research in Mexico and the world.

We analyzed the influence of humidity, temperature, and temporal and elevational distribution on the composition, abundance, and richness of rove beetle assemblages captured with carrion traps in a Quercus L. forest, Cerro de García, Jalisco, Mexico. Four sites with elevations ranging 2,100–2,700 m were surveyed. Beetles were captured monthly from September 2013 to August 2014. Three carrion traps were set at each sampling site, separated by 100 m distance. At each site, a data-logger was used to record temperature and humidity. In total, 18,054 rove beetles were captured, belonging to nine subfamilies, 11 tribes, 33 genera, and 75 species. The rove beetle assemblage showed the highest diversity during the rainy season (q = 0, 1 and 2) and the lowest during the dry season. The composition of the assemblage at 2,700 m elevation was mainly influenced by humidity and at 2,100 m by temperature. Beta diversity in the Quercus forest at different elevations and collecting periods was best explained by species replacements (shifts), and the interaction of humidity and temperature.

We present the species diversity of rove beetles (Coleoptera: Staphylinidae) collected with carrion baited traps in Quercus forests of Cerro de García, Jalisco, and provide a compilation of published species records in Quercus, Quercus-pine and pine forests in other jurisdictions of Mexico. This work includes taxonomic notes, information on species phenology, distribution, and their occurrence in Cerro de García (if applicable), and other jurisdictions of Mexico. In Cerro de García, 75 species were collected in total, of which 16 are shared with other Quercus forests in different locations, and 9 species are provided with new habitat data. The remaining individuals were only determined to morphospecies. In Mexico, there are 77 known species of rove beetles collected with carrion traps (determined to species or near species) and recorded from Quercus, Quercus-pine and pine forests. These species belong to 30 genera, 11 tribes and 10 subfamilies. This study provides biological information on Mexican rove beetles captured with carrion traps and highlights the importance of rove beetles as indicator species of habitat change for conservation analysis, forestry, agronomy and forensic sciences studies.

We describe for the first time a potential stridulatory apparatus in Oxyporinae rove beetles (Coleoptera: Staphylinidae), which was found in all 18 studied species of the genus Oxyporus and only in three out of six studied species of the genus Pseudoxyporus. No potential stridulatory structures were found in two species of Oxyporus larvae, which we examined. We describe in detail and illustrate these potential stridulatory organs of the following species: Oxyporus mexicanus Fauvel, O. maxillosus Fabricius and O. japonicus Sharp; Pseudoxyporus cyanipennis (Kirshenblat), P. dybowskii (Solsky) and P. melanocephalus (Kirshenblat). Stridulatory structures observed in Oxyporus species involve a potential scraper on the profemur and a potential stridulatory file on the mesocoxae, while Pseudoxyporus differs in having the potential scraper on the procoxae. The specifics of the mechanics and function of this structure in Oxyporinae are unknown but we discuss the various possibilities including association with their subsocial behaviour. The systematic implications of our discoveries for the generic classification of Oxyporinae are discussed. In particular, our findings shed light on the systematic position of Oxyporus smithi Bernhauer, a species from Mexico with ambiguous affinities.
