  First documented cases of invertebrate predation by greater grisons (Galictis vittata) Abstract  We report the first documented predation of invertebrates by greater grisons (Galictis vittata) based on camera-trap footage from a mineral lick in Southeastern Peru. Two adult individuals were recorded capturing and consuming large arachnids, likely whip spiders (Amblypygi), from a natural cavity. One grison visibly removed and discarded part of the prey prior to ingestion, suggesting selective handling to reduce risk from defensive structures. These observations extend the known cavity-focused foraging behavior of G. vittata and indicate that amblypygids may represent an underreported but regular prey item in tropical habitats.

Abstract

The family Agelenidae is mainly distributed in the Middle East, Asia, and Africa, with genera present in North and Central America, including the genus Melpomene O. Pickard-Cambridge, 1898. This article describes and illustrates the species Melpomene dobida sp. nov. (male, female), which is the first endemic species of Agelenidae for Colombia, Melpomene bocadelmonte sp. nov. (female) from Panama and includes a complementary description of Melpomene panamana (Petrunkevitch, 1925) (female).
