Both the originally described Pamphobeteus nigricolor and the species widely available in the hobby, Pamphobeteus sp. “nigricolor,” are large, black tarantulas. At the hobbyist level, P. sp. “nigricolor” is sharply distinguished as a different species by a Christmas tree rump pattern on spiderlings and juveniles. Only in the past few years have small numbers of what is thought to be the original, or true, P. nigricolor (Colombia) become available to hobbyists. These have come by way of Germany, either captive-hatched or captive-bred. We will import them again in the future, hopefully more affordably.
Meanwhile, the species listed on this page has been widely available since 2000. It has been sold under various names, including P. nigricolor (inaccurate), P. cf. nigricolor (better) and P. sp, “nigricolor.” We use the last (third) name, as the species is clearly different from P. nigricolor.
In 2008, Bertani et al  published an article that included a summary of the distribution of Pamphobeteus nigricolor with the following statement, “Pamphobeteus nigricolor, formerly described from Colombia, Ecuador and Bolivia, is recorded from Brazil and its distribution in Ecuador and Bolivia is questioned.”
The country of origin of P. sp. “nigricolor,” the species listed on this page, is Ecuador. Hobbyists praise P. sp. “nigricolor,” no matter the name used; it’s easy to understand why. Care requirements are as for Pamphobeteus in general. The spiderling/juvenile females offered here were raised from spiderlings bred overseas and sexed by molt. Males also available, please request.
The photo at the top of the page shows a recently molted, semi-adult female.
