vitelligera species group
Diagnosis.
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.
