Reversopelma shows strong
sexual dimorphism, the female being light brown on the
cephalothorax and having a black abdomen, whilst the male is much darker overall. It is quite small (30–35 mm), and the
scopulae on the fourth
tarsus of the legs are divided by bristles. The
embolus is long and quite wide. The male has
urticating hair Type III, and the female has modified Type I, which are divided twice. The fourth
metatarsus is not scopulate. ==As a pet==
