  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.

A new species of pelican spider (Araneae: Archaeidae) from the Whitsunday hinterland of central-eastern Queensland

Abstract 

Pelican spiders of the genus Austrarchaea Forster & Platnick, 1984 (family Archaeidae) are well represented in the tropical rainforests of central-eastern and north-eastern Queensland, with nine species currently described. However, this monophyleytic tropical fauna remains poorly documented relative to other lineages of Archaeidae from subtropical and temperate regions south of the St Lawrence Gap, with numerous additional species likely still unnamed. Here, we describe a new species from the Central Mackay Coast bioregion of central-eastern Queensland. Like other Australian Archaeidae, it is a shortrange endemic taxon, known only from upland rainforest habitats in the Whitsunday hinterland near Airlie Beach. We show its clear morphological affinities to a closely related species from Eungella National Park, and further provide live habitus images and habitat information.
