Atomosphyrus Simon, 1902: 405( typespecies by original designation: Atomosphyrus tristiculus Simon, 1902); Galiano 1963b: 305(redescription of typespecies and treated as invalid genus by typespecies inquirenda); Galiano 1966(revalidation); Richardson 2010; Ruiz & Maddison 2015; Maddison 2015; World Spider Catalog 2017.
Diagnosis. Atomosphyrusresembles Thiodina, Cyllodania, Hyetussa, Arachnomuraand Tartamuraby having spine-like setae on the anterior surface of male chelicera ( Fig. 5B) (hard to see in black species, such as At. tristiculus, without an adequate light and contrast, or without SEM). The genus differs from Hyetussaby the filiform embolus curling around the bulb (see Galiano 1966: figs 5‒6, 15‒16); from Thiodinaby the absence of dorsal abdominal pattern ( Figs 1A‒1D) (abdomen entirely black in Atomosphyrus); from Arachnomuraand Tartamuraby having a keel on the anterior face of male chelicera; and from Cyllodaniaby this keel being strongly modified into a “mastidion” in Atomosphyruson the proximal portion of male chelicera ( Figs 5A‒5C; also see Galiano 1966: figs 10, 12), and by the filiform embolus. List of species(chronological order): 1. Atomosphyrus tristiculus Simon, 1902(type species). 2. Atomosphyrus breyeri Galiano, 1966.
