“…La mirmecofauna recolectada en los ambientes urbanos de Santa Marta representan alrededor del 64 % de las subfamilias registradas para el Neotrópico y Colombia, así como el 40 % de los géneros en Colombia (Fernández et al, 2019a). De los 97 taxones determinados, 88 fueron identificadas a nivel de especie, correspondiendo al 8 % de los registros actuales para el país (Fernández et al, 2019a;García et al, 2020). Las subfamilias Myrmicinae, Ponerinae, Formicinae y Pseudomyrmecinae contribuyeron con cerca del 88 % de la riqueza de hormigas, tendencia que se mantuvo relativamente constante entre los ambientes urbanos evaluados (Figura 1).…”

Se presenta una base de datos de acceso público a través del Sistema de Información de Biodiversidad en Colombia (SIB), de las hormigas asociadas a fragmentos de bosque seco y ambientes urbanos de Santa Marta, Colombia. Los métodos de captura incluyeron la instalación de trampas de caída, cebos de proteína y carbohidratos, extracción por el método Winkler de las hormigas asociadas a la hojarasca y la recolección manual de aquellas que forrajeaban sobre la vegetación arbórea. El conjunto de datos contiene 54 323 registros, distribuidos en siete subfamilias, 42 géneros, 88 especies y nueve morfoespecies. El presente listado es una herramienta para incentivar el estudio y conservación de las hormigas en áreas urbanas.

Non-native ants are breaking down biogeographic boundaries and homogenizing community assemblages

As geographic distance increases, species assemblages become more distinct, defining global biogeographic realms with abrupt biogeographic boundaries. Yet, it remains largely unknown to what extent these realms may change because of human-mediated dispersal of species. Focusing on the distributions of 309 non-native ant species, we show that historical biogeographic patterns have already broken down into tropical versus non-tropical regions. Importantly, we demonstrate that these profound changes are not limited to the distribution patterns of non-native ants but fundamentally alter biogeographic boundaries of all ant biodiversity (13,774 species). In total, 52% of ant assemblages have become more similar, supporting a global trend of biotic homogenization. Strikingly, this trend was strongest on islands and in the tropics, which harbor some of the most vulnerable ecosystems. Overall, we show that the pervasive anthropogenic impacts on biodiversity override biogeographic patterns resulting from millions of years of evolution, and disproportionally affect particular regions.

Pheidole is one of the most diverse groups of ants in the World, with more than 630 species known from the Neotropical Region. As part of studies on the ant fauna of Colombia, a contribution to the taxonomy of these ants is presented here. The worker subcastes of Pheidole praeusta Roger are redescribed, this being the first record of a trimorphic species outside the Nearctic region. Pheidole amata Forel is proposed as a junior synonym of Pheidole praeusta. Pheidole rogeripolita Longino is identified as the first species in the New World with a 5-segmented antennal club, and the third species with such antennal club in the world. Pheidole distorta Forel, a species described 120 years ago, is redescribed, and notes on its reproductive caste are offered. The description and diagnosis of the Pheidole iceni Fernández soldier is amended. New species records for the country and South America are listed. Multifocus photographs of P. praeusta, and P. rogeripolita are offered.
