Bumba cabocla, from the Maracá Ecological Station in the state of Roraima, Brazil, is a robust, yet delicate-appearing theraphosid. All instars have thin, tapered legs and short setae. Color is black with a port-wine, maroon carapace.

Roraima shares its northern border with Venezuela and Guyana. The border is a mountainous, drainage divide. At one point it is distinguished by highland tepuis, where Roraima meets La Gran Sabana–home to P. irminia. Rainfall here enters Venezuela’s Orinoco Watershed, flowing north to the Atlantic. In Roraima, south of the Sabana, elevation drops precipitously. Rainfall supplies a different watershed.

Only 50 miles/80 km south of the Venezuelan border is Maracá Island [2] on the Uraricoera River. The island was designated an ecological research station in 1981. Here is an outlying research camp and a forest cover sample.

Maracá is one quarter the size of Rhode Island. West and east Maracá are influenced by Amazonian forest and Guyana savanna respectively.

Maracá and the nearest city, Boa Vista, lie at low-altitudes. Boa Vista climate is Köppen Aw-–tropical savanna with a wet season (summer). Temperatures hover around 80F year round, +/- 5F, precipitation 60.4 inches (1534 mm) yearly.

Mature female and male B. cabocla can reach 4+”. Captive B. cabocla tolerate a wide range of conditions. They do well with dry substrate and some form of water access. Water can be provided ad lib via a water dish, or with regular feeding and perhaps occasional spritzes for drinks.

B. cabocla has been bred overseas and in the US, presenting no unusual requirements.
