Titanoecidae is a spider family with five genera and more than 50 species worldwide. The family is fairly widespread in the New World and Eurasia. Once part of the family Amaurobiidae, these are mostly dark-colored builders of "woolly" (cribellate) silk webs. The main genus is Titanoeca. Several species are found at relatively high altitudes in mountain ranges and may be very common in such habitats.
