The general colour is blackish brown, with long orange-red hairs on the abdomen and legs.

[2] The palpal bulb has a wide embolus tapering to a point,[2] typical of Brachypelma species (as then understood) as opposed to the long tapered embolus of Euathlus species.

[3] In a study published in 1992, Andrew Smith described a specimen in the British Museum of Natural History believing it to be a male of Euathlus truculentus.

He used his description to support the view held at the time that the genus Brachypelma was synonymous with Euathlus.

[2] However, shortly afterwards in 1992, Günter Schmidt realized that this specimen was not the same species as the type of Euathlus truculentus, but was in fact a new species of Brachypelma (as then understood), which he called B. andrewi after Andrew Smith.
