Females of this species group are identified by a unique combination of characters: head unarmed posterolaterally; mesonotum rounded laterally, lacking longitudinal medial carina; scutellar scale distinct, connected to anterior transverse carina; apex of middle and hind femora truncate; T2 having four integumental spots; gena carinate; pygidium broadly ovate. Males can be diagnosed by having the parameres conspicuously sinuous, with an isolated medial tuft of long setae ventrally; cuspis virtually straight and overall asetose, except for a small tuft of short setae apically. External characters include white meso- and metatibial spurs, truncate axilla, mesopleuron with blunt tubercle; hypopygium trapezoidal and T3–5 entirely clothed with white setae. Included taxon. Traumatomutilla vitelligera ( Gerstaecker, 1874 ) . Distribution. Traumatomutilla vitelligera has been recorded from six South American countries, but we have seen specimens only from semiarid regions of Ecuador , Peru and Chile . Remarks. The vitelligera group is one of the three species groups of Traumatomutilla with only one species, T. vitelligera ( Gerstaecker, 1874 ) . As in T. diabolica ( Gerstaecker, 1874 ) , the mesosomal sculpture of T. vitelligera differs from other large-bodied Traumatomutilla by lacking the distinctive structures of the more diverse, large-bodied species groups [medial longitudinal mesonotal carina (indica), bilobate anterior transverse carina separated from scutellar scale (juvenilis), and lateral mesonotal tubercles (quadrinotata)]. The lectotype of T. vitelligera , however, has a conspicuous scutellar scale connected laterally with its anterolateral carinae, as in many species of the indica group. Additionally, aside from a few species found in northwestern Colombia , this is the only species in Traumatomutilla known west of the Andes.
