Hickmania is a genus of cribellate spiders with a single species, Hickmania troglodytes, known as the Tasmanian cave spider, that occurs only in Tasmania, where it is widely distributed, especially in underground drainage and cave systems, where large numbers can be found in the entrances. They are up to 2 cm long, with a legspan of up to 18 cm; its web can have a diameter of more than one meter. The smaller males have a distinct kink-like curve near the end of each second leg. These kinks are used to hold the female's head while mating.
