Introduction
I am an entomologist interested in studies with a focus on taxonomy, phylogenetic systematics, historical biogeography, geometric morphometry and biological conservation, and I use the Coleoptera order as a model group, although I am also interested in applying the analytical tools of these disciplines to other groups of organisms.
My study group, the order Coleoptera, is the most diverse taxon in the animal kingdom, with great ecological and economic importance...

Las larvas de Coleopteros del género Phyllophaga representan un riesgo para la seguridad alimentaria en Oaxaca y todo México. Para México las pérdidas - brada, mientras que para el estado de Oaxaca los daños llegan hasta el 90%. El objetivo del trabajo es determinar qué zonas agrícolas están en mayor ries- go por Phyllophaga en escenarios de cambio...
Deforestation and land use changes are major drivers of biodiversity decline. At the genetic level, these human activities restrict gene flow and
increase the effects of genetic drift and inbreeding, reducing a populations’ capacity to respond and adapt to changing environments. We pro-
duced novel genomic data (Single Nucleotide Polymorphisms [SNP...
1. Ecological niche models and species distribution models (SDMs) are tools used to define a species’ niche based on presence records and to identify areas where appropriate ecological conditions converge, indicating zones of potential distribution for the species. SDMs help optimize conservation efforts, which is particularly important in countrie...
The Megalopolis of Central Mexico is among the most densely populated urban areas in the World, but this area has some Natural Protected Areas, such as the Iztaccíhuatl-Popocatepetl and La Malinche National Parks. The aim of this work is to study the biodiversity patterns of photophilic scarab beetles (Scarabaeoidea) in the aforementioned national...
Throughout the months from May to August 2022, using a black light trap, melolonthid scarabs were sampled in a low deciduous forest area in the coastal region in the Oaxaca state, southeastern Mexico. Within the collected material, specimens of an undescribed species of the genus Phyllophaga Harris, 1827 (s. str.) belonging to the rorulenta species...
The longarm river prawn, Macrobrachium tenellum (Smith, 1871), is an amphidromous species inhabiting rivers, estuaries, and coastal lagoons along the Pacific slope of the Western Hemisphere, having morphological differences depending on habitat. The species has an important ecological role, playing a crucial position in coastal-river equilibrium. T...
Insects are the most diverse group of organisms, but their large number of species and the lack of specialists to study them have made this group particularly vulnerable to the main limitations in biological diversity, such as the Wallacean deficit. This study will contribute to the geographical knowledge of an insect trophic guild that has been wi...
Male genitalia morphology in Myrmeleontidae has traditionally been insufficiently studied, although it has received increased attention for its diagnostic value in recent times. A neutral terminology has generally been applied in standard taxonomic practice, yet knowledge of an equivalent and stable terminology across taxa based on comparative morp...

Assignation of old type specimens is important for nomenclatural stability, but when it comes to ancient specimens, the use of certain techniques is sometimes not appropriate, due to the condition or age of the specimen. In this study, the supposedly polymorphic and monotypic genus Callirhinus Blanchard was analysed with geometric morphometric tech...

Based in this condition, Eucanthus is proposed a...
Insectivorous bats exhibit food preferences for specific attributes in their prey. Hardness has been defined as an important prey attribute, and in some cases a limiting factor in foraging decisions for smaller compared to larger bat species. The goal of this study was to identify which factors influence the selection of prey hardness in a vesperti...

The origin and function of exaggerated traits exhibited by a great number of species with sexual dimorphism remain largely unexplored. The usual model considered as the evolutionary mechanism for the development of these structures is sexual selection. The nature of growth of the postocular flange (POF) in three species of the dobsonfly genus Platy...

INTRODUCCIÓN Dentro del género Anomala Samouelle, 1819 se han definido categorías supraespecíficas con criterios taxonómicos y morfológicos heterogéneos que en numerosos casos dificultan su diagnóstico mediante una única combinación de caracteres (v.g. Burmeister, 1844; Blanchard, 1851; Bates, 1888; Casey, 1915; Machatschke, 1957, 1972; Ohaus, 1918...
