Psalmopoeus reduncus
An arboreal tarantula from Central America. Orange setae around the chelicerae give it its common name; the body is chestnut brown and the abdomen may show chevrons. It has no urticating hairs and is extremely fast.
Psalmopoeus reduncus is an arboreal tarantula found in Costa Rica, Panama and Nicaragua, described by Karsch in 1880. Its common name comes from the orange setae around the chelicerae. The body is chestnut brown and may develop chevrons on the abdomen, while juveniles have a more golden to copper-coloured abdomen. Leg span reaches about 15 cm; females live up to about 12 years and males up to three. Like others in the genus it lacks urticating hairs and relies on flight and biting for defence. It is a very fast-moving spider that runs rather than standing its ground, and it is fairly reclusive, staying in its hide for most of the day. Members of the genus have stridulatory lyra on the maxillae, a feature said to be unique to Psalmopoeus among New World tarantulas.
