Cyriopagopus lividus
A fossorial tarantula from Southeast Asia with iridescent blue legs. It stays deep in its burrow and is rarely seen, and its medically significant venom and defensiveness make it an advanced species.
Cyriopagopus lividus belongs to the Ornithoctoninae and inhabits tropical rainforest from Myanmar across the border into Thailand, with its type locality at Kawkareik in Kayin State, Myanmar. Smith described it as Haplopelma lividum in 1996, and it took its current name when the genus Haplopelma was dissolved in 2015. Its defining feature is its iridescent blue legs, set against a light grey prosoma and opisthosoma, the latter sometimes carrying darker grey chevrons. Males look like females until their final moult, after which they become light tan and leggy. An obligate burrower, it spends nearly all its life in deep burrows of its own construction and is seldom seen even in captivity. Its venom is not life-threatening, but a Japanese case report records severe pain and inflammation with stiffness lasting weeks. It is defensive and fast, and so is considered a species for advanced keepers.
