Taxonomic notes on Barinas: a new generic synonym, a new cave-dwelling species, and new records from Colombia (Arachnida, Opiliones, Agoristenidae)

Abstract

Barinas guanenta sp. 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.
