Acanthogonatus nahuelbuta
Acanthogonatus nahuelbuta is a mygalomorph spider of Chile, named after its type locality: Piedra del Águila, Parque Nacional Nahuel-Buta, Malleco.[1] Males differ from A. patagallina by having the basal portion of the bulb less rounded and the basal loop of the bulbal duct less sinuous; and from those of A. hualpen by the differently shaped embolus and the palpal tibia with the apical two-thirds (instead of its apical one-third) tapering gradually and having thickened setae.

gollark: But the waterwheel as specified will make AC. The calculator uses DC, probably.
gollark: Technically, we just remotely read the buttons and write to the LCD using repurposed orbital mind control lasers.
gollark: * work
gollark: Ah, the memetics convincing you that your project work works!
gollark: Yes, making DC would be more annoying.
