Distribution: Tamaulipas Province, and Veracruzan Province. Note: The specimens from Ejido El Sabinito and Reynosa were identified as A. maculatum because they present two spurs on tibiae II-IV; however, the female from Ejido El Sabinito morphologically resembles morphotype III referred to by Lado et al. (2018), which is characterized, among other characters, by presenting one spine and one seta on tibiae of legs II-IV; while the specimens from Reynosa (CNAC002059) resemble morphotype II, which is characterized by presenting two small spurs on tibiae of legs II-IV. See additional comments on A. triste.
