Diagnosis. Female. In addition to structural characters referenced in the species groups diagnosis, T. vitelligera   can be diagnosed by the following: head mostly clothed with silvery-white setae, mesosomal setae almost entirely black. Sculptured area on mesopleural ridge broad, densely and coarsely areolatepunctate. Male. Males of T. vitelligera   can be diagnosed by their unique color pattern: having entirely black integument with head mostly and T3–5 completely clothed with dense silvery-white setae as well as blunt tubercles on dorsal half of mesopleuron, truncate axillar projections, and elongate hypopygium.

Metasomal setae predominantly black except for part of T1, lateral felt line and lateral setae of T2, fringe of T2–4, most of T5–6 and most of S1–6 with silverywhite setae varying in density. Some females differ by having more extensive silvery-white setae on the head or on the size of the integumental spots of T2 which can be conspicuously larger and much more closely spaced. The extent of white setae areas on the metasoma may also vary, especially on S2–4 on which it may be greatly reduced to the point of lacking on the fringes of S 2–3 in some cases. Male.

Mesosomal setae predominantly black with silvery-white setae varying in density medially on metanotum, posterior and lateral face of propodeum, and basal third of mesosomal pleurae. Legs setae predominantly black except few silvery-white setae on femora and dense silvery-white setae on internal surface of hind tibia. Metasomal setae predominantly black except with most of T1, T2 basolaterally, felt lines, fringe of T3–5 and S3–5, posteromedian pit of S2 and disc of S2 partially, with silvery-white setae varying in density.

Distribution. Ecuador, Peru, Chile.

Host. Unknown.

Remarks. The distinctive setae pattern in T. vitelligera   can be approximated by other species that have their bright mesosomal setae patches lost or obscured due to specimen wear or condition. According to Nonveiller (1990), this species has been recorded from Peru, Venezuela, Ecuador, Brazil, Paraguay and Chile. However, we have only seen valid records of T. vitelligera   from Ecuador, Peru and Chile and hypothesize the historical records from other countries are based on misidentified or mislabeled specimens. Examination of the types of T. fascinata   and T. comata   , as well as dissection of the genitalia of both species, indicate that they are virtually identical, except that the silvery-white setae areas on T. comata   are less extensive and conspicuous than on T. fascinata   . Additionally, both the lectotype and paralectotype of T. comata   have an incomplete vein arising from the rs vein at the first submarginal cell ending halfway towards the base of the pterostigma. Given that the remaining characteristics of these specimens are virtually identical to specimens of T. fascinata   , this abnormal vein is possibly some sort of malformation or teratoma, or a case of intraspecific variation. Additionally, variations in the venation of the right and left forewing of a mutillid may occur in the same specimen ( Quintero and Cambra 2005). With the exception of a few species from the inermis and indica species groups in northwestern Colombia, T. vitelligera   , T. fascinata   and T. comata   are the only species of Traumatomutilla to occur west of the Andes. Therefore, we associate T. vitelligera   with T. fascinata   syn. nov. and T. comata   syn. nov. based on their overlapping geographical distribution and congruence of taxonomically important characters.
