The first record of the genus Gracilidris (Hymenoptera: Formicidae: Dolichoderinae) from Colombia

Roberto J. Guerrero

Abstract: The dolichoderine ant genus Gracilidris and its sole species, G. pombero, are recorded for the first time for Colombia from populations from the foothills of the Colombian Amazon basin. Comments and hypotheses about the biogeography of the genus are discussed.

The dolichoderine ant species Gracilidris pombero, sole representative of the genus, is recorded for the first time in southern Brazil. Until now, the species was known only for the open fields of the South American dry diagonal and for a single locality in the Colombian Amazon. The specimens reported here were collected with pitfall traps in grasslands of the Pampa biome, state of Rio Grande do Sul, Brazil. This record represents the southernmost occurrence for the genus, extending its distribution in approximately 450 km to the south in the Neotropics and in almost 1,150 km to the south in Brazil.

Gracilidris pombero Wild & Cuezzo, 2006 is an ant that remains poorly studied. Endemic from South America, its geographical distribution is known from few and scattered collection points. In this study, we present new occurrence records of G. pombero obtained through extensive collections along the Cerrado biome and the Atlantic Forest of northeastern Brazil. Based on the new and existing occurrence records we produced a model of the geographic distribution of G. pombero. Modelling method was chosen based on maximization of model performance after evaluating a series of modelling approaches, including different parametrizations of the Maxent algorithm and distinct runs of the GARP algorithm. We found a total of 43 new records of G. pombero in Brazil, including the first records of this species in the states of Goiás, Mato Grosso do Sul, Piauí, Sergipe and Tocantins. Based on our model, the areas of highest suitability of occurrence of G. pombero are located in two main zones in South America: one ranging from midwestern Brazil to southeastern Bolivia and Paraguay; and the other spanning the South of Brazil and Uruguay.

ResumenEl Grupo de Investigación en Biología, Ecología y Manejo de Hormigas de la Universidad del Valle ha publicado en las últimas dos décadas 60 estudios llevados a cabo en diferentes ecosistemas colombianos que abarcan paisajes rurales, áreas protegidas y zonas agrícolas y urbanas. El 70 % de las contribuciones se concentró en la región Andina, seguida de las regiones Pacífica, Insular, Amazonia y Orinoquia, cada una con el 7 %, y un 2 % en la región Caribe. En cuanto al número de especies de hormigas registradas, sobresalieron las zonas con mayor esfuerzo de muestreo como las tierras bajas del Pacífico (227 especies), el valle interandino del río Cauca (215 especies), el piedemonte amazónico en el departamento de Caquetá (132 especies), el Parque Nacional Natural Gorgona (129 especies) y la región Caribe (122 especies). Los estudios incluyeron algunas especies de hormigas clave, ya sea por su rareza, endemismo, amplia distribución o comportamiento invasivo, y, así mismo, aquellas catalogadas como indicadoras de hábitats o usos del suelo, de diversidad y de perturbación del ecosistema. Igualmente, en los estudios se mencionan los servicios ecosistémicos a los que contribuyen varias especies.Palabras clave: áreas protegidas, bioindicadores, riqueza de especies, paisajes rurales, servicios ecosistémicos. Two decades of study of the diversity of ants in Colombia AbstractThe Research Group on the Biology, Ecology, and Management of Ants at the Universidad del Valle has published 60 studies in the last two decades on different Colombian ecosystems, including rural zones, protected areas, crops, and urban areas. Seventy percent of the contributions concentrated in the Andean region, followed by the Pacific, Insular, Amazon and Orinoco regions, each with 7%, and 2% in the Caribbean region. In terms of number of species, the ant diversity recorded reflects areas with greater sampling effort, such as the Pacific lowlands (227 species), the Andean valley of the Cauca river (215 species), the Amazon piedmont in the department of Caquetá (132 species), the Gorgona Natural National Park (129 species), and the Caribbean region (122 species). Studies include some key species of ants due to their rarity, endemism, wide distribution, or invasive behaviour, as well as those classified as indicators of habitats and land uses, diversity, and ecosystem disturbance. Ecosystem services to which various species contribute are also mentioned.
