Abstract
Three species of Avima are recorded for the first time from Colombia (La Guajira department): A. venezuelica Soares & Avram, 1981, A. troglobia (Pinto-da-Rocha, 1996), and A. wayuunaikiSp. nov. Complementary and new descriptions of the species are offered and scanning electron microscopy photographs of the male genitalia of A. troglobia are given.
Highlights
The family Agoristenidae is a small and unusual group of Neotropical harvestmen (27 genera and 78 described species), found mainly in leaf litter, under rotten logs and rocks, and over rocky walls (Ahumada-C. et al 2020; García and Kury 2020)
In Colombia, the subfamily is represented by seven genera and nine species (García and Pastrana 2021, Kury et al 2021, Villarreal and García 2021), two of them being members of Avima Roewer, 1949: Avima scabra (Roewer, 1963) and Avima tuttifrutti García & Pastrana, 2021, from Cundinamarca and Córdoba departments, respectively (García and Pastrana 2021)
In the present work, we discuss some aspects of the harvestmen biodiversity of La Guajira and offer complementary and new descriptions, photographs of the general habitus, and Scanning Electron Microscopy (SEM) images of some of the male genitalia, together with a distributional map of the three species in Northern South America
Summary
The family Agoristenidae is a small and unusual group of Neotropical harvestmen (27 genera and 78 described species), found mainly in leaf litter, under rotten logs and rocks, and over rocky walls (Ahumada-C. et al 2020; García and Kury 2020). It is currently divided into three subfamilies: Agoristeninae Šilhavý, 1973, Leiosteninae Šilhavý, 1973 and Globibuninae Kury, 2012. Leiosteninae contains 13 genera and 60 species, distributed mainly in northern South America. In the present work, we discuss some aspects of the harvestmen biodiversity of La Guajira and offer complementary and new descriptions, photographs of the general habitus, and SEM images of some of the male genitalia, together with a distributional map of the three species in Northern South America
