Geogamasus cuneatus is a species of predatory mite belonging to the order Mesostigmata and the family Parasitidae. It was first described by G. Owen Evans in 1955.

Description As a mesostigmatid mite, Geogamasus cuneatus is a relatively small arachnid, typically microscopic or barely visible to the naked eye. Mites in the family Parasitidae are characterized by their well-sclerotized bodies and often exhibit adaptations for a predatory lifestyle, including chelicerae (mouthparts) modified for grasping and piercing prey. The specific epithet "cuneatus" is Latin for "wedge-shaped," which may refer to a particular morphological feature of the species.
Habitat and Distribution Geogamasus cuneatus is primarily known from New Zealand. It is a soil-dwelling species, typically found in various terrestrial microhabitats such as soil, leaf litter, mosses, and decaying organic matter. These environments provide both shelter and a rich source of potential prey for the mites.
Ecology Like other members of the family Parasitidae, Geogamasus cuneatus is a predatory mite. It plays an important role in soil ecosystems by preying on other small invertebrates, including nematodes, collembolans (springtails), and the eggs or larvae of various insects. Through their predatory activities, these mites contribute to the regulation of soil invertebrate populations and participate in nutrient cycling and decomposition processes within their habitats.
Conservation Status The conservation status of Geogamasus cuneatus has not been formally assessed by major conservation organizations such as the IUCN Red List. This is typical for many soil-dwelling invertebrate species, which are often poorly studied in terms of their population dynamics and vulnerability.
