Ricinulei(redirected from Hooded tickspider)
an order of the class Arachnida. The body, which reaches 1 cm in length, is divided into a cephalothorax and a wide, segmented abdomen. The abdomen ends in a small, tightly constricted section known as the postabdomen. The movable hood of the cephalothorax folds over small two-jointed chelicerae. A six-legged larva hatches from the egg (as in ticks). There are about 15 species, distributed in western Africa and South America.
