Acanthogonatus quilocura
Acanthogonatus quilocura is a mygalomorph spider of Chile, its name referring to the seemingly unending number of species within this genus (“locura” meaning madness in Spanish).[1] Males are similar to those of A. tacuariensis (from Uruguay), from which are distinguished by a curved metatarsus I; female spermathecae are characteristic in having a strongly bent duct arising from the base of a blunt basal dome.

Its sternal sigilla is small and oval, connected to the sternal margin by a depression; the sternum is slightly rebordered. Chelicerae: the rastellum is formed by thickened, attenuate setae. Spermathecae have their lateral duct strongly bent. Color as in male.[1]
