}}Acanthogonatus hualpen is a mygalomorph spider of Chile, named after its type locality: Hualpén, Concepción, Bío Bío Region.[1] Males can be distinguished from those of A. nahuelbuta and A. patagallina by the shaped of the bulb's apex, and by the palpal tibia being wide in the basal two-thirds (tapering abruptly at the apex) with thickened setae along the apical one-third of the retrolateral face (instead of two-thirds). Description- Male: total length {{convert|9.42|mm|in}}; cephalothorax length {{convert|4.08|mm|in}}, width {{convert|3.25|mm|in}}; cephalic region length {{convert|2.66|mm|in}}, width {{convert|1.92|mm|in}}; medial ocular quadrangle (OQ) length {{convert|0.45|mm|in}}, width {{convert|0.84|mm|in}}; labium length {{convert|0.34|mm|in}}, width {{convert|0.79|mm|in}}; sternum length {{convert|1.2|mm|in}}, width {{convert|0.99|mm|in}}. Its labium and maxillae possess no cuspules; its maxillae have thickened setae on their anterior inner corner. A serrula is present. Its sternum and sigilla resemble those in A. nahuelbuta. Chelicerae: rastellum is absent. Cheliceral tumescence is small, with a ventral protuberance. Leg I and its tibial apophysis is similar to that of A. Nahuelbuta, while its metatarsus is straight. Its color is also as in A. Nahuelbuta.[1]
- Female: total length {{convert|12.5|mm|in}}; cephalothorax length {{convert|4.90|mm|in}}, width {{convert|3.92|mm|in}}; cephalic region length {{convert|3.32|mm|in}}, width {{convert|2.6|mm|in}}; fovea width {{convert|0.62|mm|in}}; OQ length {{convert|0.49|mm|in}}, width {{convert|0.95|mm|in}}; labium length {{convert|0.47|mm|in}}, width {{convert|0.85|mm|in}};sternum length {{convert|2.52|mm|in}}, width {{convert|2.27|mm|in}}. Its cephalic region is convex, with the fovea slightly procurved. Its labium possesses 1 cuspule. A well-developed serrula is present. Its sternal sigilla is small, shallow and marginal. Chelicerae: rastellum is absent. Color as in male.[1]
