Abstract

Background: The Colombian Amazon is a region of remarkable biodiversity; however, several biological groups and their microhabitats remain poorly explored. Recent studies on soil ant diversity have provided new records and insights into their biology. Sampling techniques focused on exploring the soil interior (monoliths) and leaf litter have led to numerous new ant records for Colombia, as well as range expansions for many species previously known from other regions.

New information: Seven new species records are reported for the country and the distribution of 14 species is extended within the Department of Caquetá. These 21 records belong to five subfamilies and sixteen genera. For the first time, the genera Lenomyrmex (Fernández & Palacio), Myrmelachista (Roger), Oxyepoecus (Santschi) and Stegomyrmex (Emery) are recorded for the Colombian Amazon. Additionally, the first case of an ergatoid queen in Probolomyrmexkelleri (Oliveira & Feitosa) is documented. The northernmost records of Adelomyrmexstriatus (Fernández) and Centromyrmexgigas (Forel) are also reported. Morphological observations, distribution data and images of all recorded species are included. The specimens were collected using the Tropical Soil Biology and Fertility (TSBF) and Winkler extraction methodologies. Furthermore, we present a checklist of ants from Caquetá, listing 321 species for the Department. Finally, we update the known ant diversity of Colombia, reporting a total of 1.280 species and 110 genera.

来自亚马逊地区的土壤和落叶蚁为哥伦比亚提供了新的分布记录。

背景：哥伦比亚亚马逊是一个生物多样性显著的地区；然而，一些生物类群及其微栖息地仍未得到充分探索。近年来对土壤蚂蚁多样性的研究为其生物学研究提供了新的记录和见解。以探索土壤内部（巨石）和凋落叶为重点的采样技术为哥伦比亚带来了许多新的蚂蚁记录，并扩大了许多以前在其他地区已知的物种的范围。新资料：报告了该国的7个新物种记录，并在caquet部扩展了14个物种的分布。这21条记录分属5亚科16属。首次在哥伦比亚亚马逊地区记录到Lenomyrmex属（Fernández & Palacio）、Myrmelachista属（Roger）、Oxyepoecus属（Santschi）和Stegomyrmex属（Emery）。此外，在Probolomyrmexkelleri （Oliveira & Feitosa）中记录了第一例门形蚁后。此外，还报道了最北的Adelomyrmexstriatus （Fernández）和Centromyrmexgigas （Forel）的记录。包括所有记录种的形态观察、分布资料和图像。采用热带土壤生物与肥力（TSBF）和Winkler提取法采集样品。此外，我们还提供了一份来自caquet的蚂蚁清单，为本部门列出了321种蚂蚁。最后，我们对哥伦比亚已知蚂蚁的多样性进行了更新，共报告了1,280种和110属。

期刊介绍： Biodiversity Data Journal (BDJ) is a community peer-reviewed, open-access, comprehensive online platform, designed to accelerate publishing, dissemination and sharing of biodiversity-related data of any kind. All structural elements of the articles – text, morphological descriptions, occurrences, data tables, etc. – will be treated and stored as DATA, in accordance with the Data Publishing Policies and Guidelines of Pensoft Publishers. The journal will publish papers in biodiversity science containing taxonomic, floristic/faunistic, morphological, genomic, phylogenetic, ecological or environmental data on any taxon of any geological age from any part of the world with no lower or upper limit to manuscript size.
