  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.

Two new wolf-spider species in the genus Hippasosa from Asia (Araneae, Lycosidae)

Abstract

Two new species of the wolf-spider genus Hippasosa Roewer, 1960 are described from Asia: Hippasosa thailandica sp. nov. (♂) from Thailand and H. yunnanensis sp. nov. (♂♀) from China. Detailed species descriptions, morphological photographs, genitalia illustrations, and distribution maps of the new species are presented. Photographs of H. qiongzhongensis (Yin & Peng, 1997) are also provided for comparison purposes.
