Phormingochilus hatihati

size 3/4” These were originally labeled ( and many times still are) as Cyriopagopus sp. hati hati  in the hobby. The problem with that, is this arboreal spider no longer fits into the genus Cyriopagopus since Smith and Jacobi’s 2015 revision, that made the burrowing spiders that we use to know as Haplopelma into Cyriopagopus. However this spider was finally described by a team of arachnologist in December of 2024 and placed in the Phormingochilus genus. The term “hati hati” is an Indonesian phrase that translates to “be careful” due to the painful bite of these spiders. The team decided to stick with that term when they described them as Phormingochilus hatihati. Adults get sizes of about 6 inches, grow fast and are easy to breed. Commonly available in the hobby these days.
