}}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. Description- Female: total length {{convert|29.6|mm|in}}; cephalothorax length {{convert|9.65|mm|in}}, width {{convert|7.45|mm|in}}; cephalic region length {{convert|6.2|mm|in}}, width {{convert|5.4|mm|in}}; fovea width {{convert|1|mm|in}}; medial ocular quadrangle (OQ) length {{convert|0.71|mm|in}}, width {{convert|1.4|mm|in}}; labium length {{convert|0.88|mm|in}}, width {{convert|1.5|mm|in}}; sternum length {{convert|4.9|mm|in}}, width {{convert|3.9|mm|in}}. Its cephalic region is convex, with its fovea slightly procurved, with a small posterior notch. Its labium possesses 3 cuspules. A well-developed serrula is present. Its sSternal 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]
- Male: total length {{convert|19.6|mm|in}}; cephalothorax length {{convert|8.9|mm|in}}, width {{convert|7|mm|in}}, cephalic region length {{convert|5.5|mm|in}}, width {{convert|4.25|mm|in}}; OQ length {{convert|0.69|mm|in}}, width {{convert|1.28|mm|in}}; labium length {{convert|0.83|mm|in}}, width {{convert|1.35|mm|in}}; sternum length {{convert|4.45|mm|in}}, width {{convert|3.48|mm|in}}. Its labium possesses 1 cuspule. Its serrula is well developed. Its sternal sigilla is elongate, with an outer side depressed, forming a connection with the sternal margin, which is rebordered. Chelicerae: rastellum is absent. Cheliceral tumescence small and pallid, ventrally protruding. Leg I and its metatarsus are curved downwards. The entire spider is a golden brown colour, while its abdomen is yellowish golden-brown with darker brown spots.[1]
