Diagnosis. FEMALE. Mesonotum as wide as distance between pronotal spiracles, lateral face of propodeum sparsely sculptured, with wide conspicuous smooth intervals; longitudinal carinae of mesonotum/dorsal face of propodeum indistinct; integumental spots of T2 yellowish, linear, anterior pair greatly reduced to absent, posterior pair confluent, forming single transverse line. MALE. Unknown.

Description. FEMALE. Body length 8–12 mm. Head. Posterior margin virtually straight. Occipital carina evenly arched and equally wide throughout. Vertex width 0.75 × pronotal width. Eye almost circular, its length in frontal view 1.15 × the distance from its ventral margin to mandibular condyle. Sculpture partially concealed by dense setae, densely and coarsely foveolate-punctate where visible; sculpture sparser on gena and malar space. Genal carina present. Mandible oblique, tapering slightly towards apex, with small subapical tooth. Dorsal scrobal carina well-defined, extending over antennal tubercles and narrowly separated from lateral scrobal carina. Antennal tubercle irregularly rugose. Flagellomere 1 2.3 × pedicel length; flagellomere 2 2.0 × pedicel length. Mesosoma . Mesosoma 0.9 × as long as wide. Mesosomal dorsum sculpture partially concealed by dense setation, densely and coarsely areolate-punctate where visible with somewhat rounded intervals; medial longitudinal carina present on mesonotum, extending from posterior margin of pronotum, narrowly interrupted in scutellar area, and nearly connecting with similar carina on dorsal face of propodeum; sculpture of mesonotum slightly less defined around medial longitudinal carina; scutellar area sculpture densely and coarsely punctate. Anterior face of pronotum defined, slightly longer than pronotal collar; with indistinct, indistinct and coarse longitudinal striations at base and dense coarse and confused punctures dorsad; dorsal face rounded into anterior face in lateral view. Humeral carina welldefined, broadly separated from slightly projected rounded epaulet, anterolateral corners of pronotum subrounded in dorsal view. Pronotal spiracle projected from lateral margin of p ronotum, rounded. Lateral face of pronotum densely punctate with dense interspersed micropunctures; with indistinct swelling anteroventral in relation to pronotal spiracle; mesopleuron sculpture mostly concealed by dense setation, micropunctate anteriorly and sparsely foveolate-punctate along mesopleural ridge where visible; metapleuron sculpture concealed by dense setation on ventral half, completely asetose, smooth on dorsal half. Lateral face of propodeum sparsely and coarsely foveolate-punctate along anterior and posterior margin, with conspicuous unsculptured area medially bearing longitudinally oblique indistinct rugosities. Ratios of width of humeral angles, pronotal spiracles, widest point of mesonotum, narrowest point of mesonotum and propodeum posterior to propodeal spiracles, 72:91:87:69:64. Lateral margin of mesonotum constricted anterior to propodeal spiracle, diverging anteriad, mesonotum with expanded lateral margins. Propodeal spiracle projected from lateral margin of mesosoma; post-spiracular area absent. Scutellar scale and anterolateral carinae virtually absent; scabrous intervals absent on scutellar area. Propodeum convex, dorsal face virtually as long as and rounded into posterior face. Metasoma. Ratios of width of T1, width of T2 and length of T2, 41:89:98. Disc of T2 densely and coarsely foveolate-punctate to punctate with dense interspersed micropunctures; foveolations sparser and micropunctures absent laterally and over integumental spots. T3–5 sculpture predominantly concealed by dense setation, densely and coarsely foveolate-punctate to simply punctate with interspersed micropunctures where visible; T6, except pygidial plate, densely and coarsely punctate. S1 surface cuneiform, densely, coarsely and confusedly foveolate-punctate around sub-sharp longitudinal medial carina equally high throughout. S2 densely foveolate-punctate, more sparsely and finely so anteromediad; anteromedial crest-fold indistinct. S3–4 sculpture mostly concealed by dense setation, densely and finely foveolate-punctate with interspersed micropunctures where visible; S5–6 densely foveolate-punctate. Pygidial plate subpyriform, defined by lateral carinae at apical fourth of plate; surface with transverse coarse and irregular rugosities; interstice granulose. MALE. Unkown.

Coloration and variations: FEMALES. Integument black to brownish-black, except mandibles and antennal flagellomeres partially reddish-brown, and T2 with single linear transverse yellowish integumental stripe on posterior fourth. Some specimens have a pair of variably developed and longitudinally linear similar stripe on anterior third. Tibial spurs yellowish-white. Body setae predominantly silvery-white varying in density, except the following areas with black setae varying in density: front, vertex and dorsal half of gena; anterior half of pronotum, posterior half of pronotum medially and laterally; dorsal half of mesopleuron and metapleuron; propodeal dorsum medially; T1 medially, disc of T2 (except over integumental spots), fringe of T2–5 sublaterally, T6 (except asetose pygidial plate) laterally; fringe of S5, and S6. MALES. Unknown.

Distribution. Brazil.

Material examined. (6♀) Type material. Lectotype: ♀, BRAZIl, [Mato Grosso], Chapada [dos Guimarães] ( CMNH) . Paralectotype: ♀, same label data as lectotype ( CMNH) . Additional material.

Remarks. Females of Traumatomutilla mundula are similar in structure to T. puella (= T. peperina and T. manca ), differing only in the integumental spots of T2 for which the anterior pair is absent or greatly reduced, and the posterior pair form a single transverse band. No definitive intermediate color forms between T. mundula and T. puella have been recorded (e.g., specimens with posterior spots separated, reduced, and anterior spots more elongated). Additionally, T. mundula is known mainly from the same areas and type locality as T. manca for which there are several specimens, including the type series, and from which no variation approximates the color pattern of T. mundula . Therefore, we maintain T. mundula as a discrete species, but will not be surprised if discovery of the male or intermediate forms lead to their eventual synonymy with T. puella .
