Abstract
Barinas guanentasp. nov. is described from a cave in Santander, central Andes of Colombia. The new species is recognized by the pedipalps and chelicerae entirely pale yellow and without variegated pattern, the areas I-IV with variegated coloration pattern and the straight stylus of the penis. The monotypic genus Vimina González-Sponga, 1987 is synonymized with Barinas, resulting in Barinas virginis (González-Sponga, 1987) comb. nov. New records of Barinas piragua Ahumada-C. & García, 2020 in La Guajira, Northern Colombia, are given. A key for the species of Barinas is given together with an updated distribution map.
Highlights
After the revision of harvestmen material from Colombia and Venezuela, we noted that the monotypic genus Vimina González-Sponga, 1987, whose type species was described from a locality near to that of B. flava, should be synonymized with Barinas
The presence of paired armature in all the mesotergal areas plus the basal DP on the stylus is a combination of characters exclusive of Barinas, so, we do no doubt about the inclusion of B. guanenta sp. nov. in it
We noted that B. flava lacks additional ornamentations above the insertion point of the DP, while the other species of Barinas exhibits both a DH or connective tissue in B. virginis comb. nov. (Fig. 3F)
Summary
The taxonomy of the Neotropical subfamily Leiosteninae Šilhavý, 1973 (12 gen., 59 spp.), widespread in northern South America, has recently aroused the interest of some researchers, resulting in several papers focused on nomenclatural acts (Ahumada-C. et al 2020; García and Kury 2020; García and Villarreal 2020; García and Pastrana-M. 2021; Villarreal et al 2021), and/or approaches to the systematics of the group (Villarreal and García 2021). 2021; Villarreal et al 2021), and/or approaches to the systematics of the group (Villarreal and García 2021). To continue on this path, the present work brings taxonomical novelties of the genus Barinas González-Sponga, 1987, that currently groups two species: the type species, Barinas flava González-Sponga, 1987 (from the Andean slopes of Venezuela), and Barinas piragua Ahumada-C. After the revision of harvestmen material from Colombia and Venezuela, we noted that the monotypic genus Vimina González-Sponga, 1987, whose type species was described from a locality near to that of B. flava, should be synonymized with Barinas. A new cave-dwelling species from the Andean region of Colombia was found. A new diagnosis for Barinas, a generic synonym with its subsequent new combination, the description of the new Colombian species, and new records for B. piragua are proposed
