Tarneides

Tarneides is a genus of spiders in the order Araneae. It is commonly placed within the family Salticidae, the jumping spiders. The genus comprises several described species that occur in the Americas and parts of Asia. Members are typically small to medium-sized and share the characteristic body plan of jumping spiders, including forward-facing eyes that provide acute vision for active hunting. Tarneides species are diurnal predators that rely on visual cues to stalk and pounce on their prey rather than constructing webs to capture food. Silk is used mainly for retreats, draglines, and egg sacs rather than for prey capture.

Habitat and distribution vary by species but often include leaf litter, bark crevices, grasses, and low vegetation in warm temperate to tropical regions. Some species are found in more arid or montane environments, while others inhabit coastal or forested areas. The genus has undergone revisions as taxonomists reassess species boundaries and relationships using morphological and molecular data.

Identification typically requires examination of male palpal morphology and female genitalia, with color patterns aiding recognition in some species. In most cases, Tarneides spiders are solitary and non-territorial, with mating rituals that involve visual signaling between sexes.

Ecological role: As generalist predators, they contribute to insect population control and serve as prey for birds and small vertebrates. Conservation status varies by species and region.
