Maratus

Maratus is a spider genus of the family Salticidae (jumping spiders). These spiders are commonly referred to as peacock spiders due to the males' colorful and usually iridescent patterns on the upper surface of the abdomen, often enhanced with lateral flaps or bristles, which they display during courtship. Females lack these bright colors, being cryptic in appearance. In at least one species, Maratus vespertilio, the expansion of the flaps also occurs during ritualised contests between males. The males' displays and courtship dances are complex, involving visual and vibratory signals. All species of Maratus are found in Australia. Several species in this genus were earlier classified in the genus Saitis, containing the Mediterranean Saitis barbipes, which is superficially similar to Maratus (colorful males with an enlarged third pair of legs). Saitis species in Australia have enlarged and fringed third legs, which they use for display, but do not raise their abdomens like Maratus. M. furvus from China was described in 1992 in the genus Lycidas, and became part of Maratus when Lycidas was synonymized in 2012. It was moved to Euochin in 2023.
