  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.

Running crab spiders (Araneae: Philodromidae) from Colombia: new species and records

Abstract
We present new records and species of running crab spiders (family Philodromidae) from Colombia representing four genera: Apollophanes O. Pickard-Cambridge, 1898, Gephyrellula Strand, 1932, Petrichus Simon, 1886, and Tibelloides Mello-Leitão, 1939. The genus Gephyrellula is recorded based on the newly described G. lavidabonita sp. nov., known from females from the department of Magdalena, constituting the northernmost known locality for the genus, at Sierra Nevada de Santa Marta. This new species can be differentiated from the (previously monotypic) type species G. violacea (Mello-Leitão, 1918), known from southeastern region of Brazil, by the longer than wide epiginal plates (wider than long in G. violacea), with narrower and shorter ducts of the glandular heads (thicker and longer in G. violacea), and by their more posteriorly placed fertilization ducts. The genus Apollophanes is here firstly recorded from males and females of A. punctipes (O. Pickard-Cambridge, 1891) from the Atlántico, Magdalena, Cesar, Cundinamarca, and Boyacá departments. Tibelloides is recorded from males and females of T. bryantae (Gertsch, 1933), from the departments of Magdalena and Meta, also representing northernmost known localities for the genus. Finally, new faunistic and taxonomic data is presented for Petrichus. Our examination of the holotype of Thanatus granadensis Keyserling, 1880 demonstrates this species is conspecific with more recently collected and better-preserved specimens of Petrichus griseus Berland, 1913, from the department of Santander. Therefore, we propose the new combination Petrichus granadensis comb. nov., regard P. griseus as its junior synonym syn. nov., and update knowledge of its distribution.
