102A879CD342FFBC3F382B404005FCFC.taxon	discussion	Remarks Bartholomay et al. (2022) mentioned that Traumatomutilla formed a morphologically consistent group along with nine other New World Sphaeropthalminae genera (Atlantilla Williams & Bartholomay, 2020, Cephalomutilla André, 1909, Dasymutilla Ashmead, 1899, Frigitilla Williams, 2015, Leucospilomutilla Ashmead, 1903, Quwitilla Williams, Bartholomay & Cambra, 2019, Reedomutilla Mickel, 1964, Suareztilla Casal, 1968 and Tobantilla Casal, 1965). This was later to be considered the Dasymutillini sensu stricto in Waldren et al. (2023), even though Atlantilla, Frigitilla, Leucospilomutilla, and Tobantilla did not feature in their analysis. Literature with keys and diagnostic characters for distinguishing these genera as well as comments regarding the complicated relationship between Traumatomutilla and Dasymutilla have been given by Bartholomay et al. (2022).	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD345FFB13F092A1B4605FDC6.taxon	discussion	Remarks The T. quadrinotata species-group is a more or less consistently large-bodied (> 10 mm) group in both sexes. The anterolateral carinae in the scutellar area – albeit partially concealed by dense setation – and the dorsolaterally expanded occipital carina observed in T. tetratrauma sp. nov. were not included in the original diagnosis of the T. quadrinotata species-group by Williams et al. (2017). Apart from these two new characters, the remaining characters for the species-group are relatively consistent and nonvariable for both sexes, most notably so for males, which apart from the length of certain genitalia setae and sculpture of the pronotal dorsum, can only be distinguished based on color and setae characters. The most conspicuous and reliable character for identifying females is the lateral expansion of the mesonotum which varies slightly from broad and blunt (e. g., T. funebris and T. quadrinotata) to narrow and tuberculiform (e. g., T. ameliae and T. sancta). The post-mesonotal tubercle is a character that was first observed in T. poranga Bartholomay & Williams, 2018 and, though it can be found in four species of the T. quadrinotata species-group, it is most conspicuous in T. quadripustulata.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD348FFB63F322BD54096FACD.taxon	discussion	Remarks The sex association of T. ameliae was based on distribution since both sexes were the southernmost records of the T. quadrinotata species-group and have been collected in the same areas across Argentina. Both sexes have consistent and apparently unvariable color and setae characters, typical of northern Argentinean mutillids. Based on structure, especially the lateral propodeal surface sculpture and lateral mesonotal expansions, females of T. ameliae are similar to T. sancta.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD34FFFAA3F0E2CEB4148FEFF.taxon	discussion	Remarks Traumatomutilla austera has a distinct color pattern (Fig. 3 A – B, E – F) that varies slightly in the mesosomal dorsum but has no intermediate forms with other known patterns. Certain specimens have patches of somewhat dense appressed silvery-white setae on the lateral surface of the propodeum that are also found in T. funebris and, more notably, in the Atlantic Forest species (T. quadrinotata and T. tetratrauma sp. nov.). The structure of T. austera, however, is different from these species, being finer and homogeneous as opposed to the overall coarser sculpture of most species within the T. quadrinotata species-group. Based on distribution, T. austera is one of four possible candidates for association with T. infernalis or T. pompiliformis.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD353FFA13CF6281D4733FE4F.taxon	discussion	Remarks The association and synonymy of T. chrysozona with T. lugubrina was initially confusing, as the females (T. lugubrina) usually have exclusively black setae, while the males are extensively covered with brilliant coppery setae. Many females in São Paulo, however, have traces of coppery setae that are the same tint as seen in males from São Paulo, and differ from the setal markings of other members of the T. quadrinotata species-group. One additional male, T. dives from Piaui and Minas Gerais, is identical to the type of T. chrysozona in every aspect except it has the propodeal dorsum clothed with dense coppery setae. Though we haven’t seen any intermediate forms between T. chrysozona and T. dives, we consider T. dives to be conspecific with T. chrysozona, as their external morphology and genitalia are indistinguishable. Further, although females of T. lugubrina are known from Minas Gerais, males of the typical form are apparently restricted to São Paulo. We therefore hypothesize that T. dives is a northern color variant of T. chrysozona. Burmeister (1854) described both sexes of Mutilla lugubris based on at least two specimens from Queluz (present day Conselheiro Lafaiete) and Ouro Preto in Minas Gerais. Gerstaecker (1874) stated that he was unable to locate the male specimen of M. lugubris, considered both sexes as distinct species, and described the male as a new species, M. burmeisteri, without actually seeing the specimen. The original description of the male of M. lugubris in Burmeister (1854) mentioned that the male has a narrow reddish band on the abdomen (meaning metasoma), and Gerstaecker (1874) placed M. burmeisteri in a subcategory that included only males with black spurs and reddish markings on the metasoma, probably based on Burmeister’s original description of the reddish band. The black spurs are evident in T. chrysozona and it’s very likely that the narrow reddish band mentioned by Burmeister (1854) is in fact his interpretation on the coppery setae clothing the fringe of T 2 – 3, especially since he used the same word “ rubra ” to define the coppery metasomal marking of Hoplocrates cephalotes (Swederus, 1787). Based on this, we place T. burmeisteri as a junior synonym of T. chrysozona.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD358FFA43F0A2B6D4292FDA1.taxon	discussion	Remarks All specimens examined are from higher altitude areas (1300 – 1700 m a. s. l.) transitioning between Cerrado and Atlantic Forest in Minas Gerais State, Brazil. Although the holotype has no indication of the specific location in which it was collected, it is also from Minas Gerais. This high-altitude distribution could be purely coincidental, but it is worth pointing out that Minas Gerais is one of the most relatively well-sampled areas in Brazil for velvet ants and no specimens of T. funebris were recorded in lower altitude areas so far. The large orange spots on T 2 (darkened by age on the holotype) and indistinct appressed silvery-golden setae on the lateral propodeal surface of T. funebris are reminiscent of the pattern observed in T. quadrinotata. Both species are nonetheless distinct structurally, especially on the sculpture of the lateral propodeal surface and shape of the lateral mesonotal projections. Similar resemblances and differences can be observed between Hoplomutilla spinosa (Swederus, 1787) and Hoplomutilla serena (Mickel, 1939) which occur in Atlantic Forest and Cerrado / Atlantic Forest areas respectively (PRB pers. obs.). Further collecting in higher altitude areas of Minas Gerais may reveal the male of this rare species.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD35DFF9B3F232B3042D1FA94.taxon	discussion	Remarks The sex association between T. incerta and T. dentata is evidenced by the distribution of both species which, to the best of our knowledge, are the sole representatives of the T. quadrinotata species-group in the northwestern Amazon Forest. Even though we were unable to access the lectotype of T. incerta, numerous specimens examined were identified as this species and compared with the type by Mickel who designated the lectotype (Mickel 1937). The lectotype designation was later confirmed by Pagliano (2005), who also officially designated the paralectotypes for T. incerta and provided a photograph of said type. Close examination of T. dentata and T. dignitosa revealed that the difference between the axillar projections (Mickel 1952) is not consistent; this, coupled with their almost identical genitalia characters, and only marginally different setal characters, is sufficient basis for synonymizing these males. Casal (1969) stated that T. tabatinga differed from T. weyrauchi (then a valid species) by having transverse irregular rugosities on the pygidial plate, which was the main difference between T. incerta and T. weyrauchi mentioned by Mickel (1945). Quintero & Cambra (1996 a) studied a paratype of T. weyrauchi and concluded that it could not be distinguished from T. incerta. Therefore, the pygidial sculpture was shown to be inadequate for differentiating species. After examining the types of T. tabatinga and T. sodalicia, we conclude that these species are also synonymous with T. incerta and T. weyrauchi. They are all basically identical in structure, differing only in the size of the T 2 integumental spots and the presence or absence of silvery-white setae on the head, with numerous intermediate specimens found between each form.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD362FF9F3CF82C2347F8FE34.taxon	discussion	Remarks Traumatomutilla infernalis is almost indistinguishable from T. pompiliformis apart from the length of the cuspis in relation to the length of the paramere and minor characters of the penis valve and setae pattern. Based on distribution this could be a putative male for T. sancta. A female of T. sancta and a male with an intermediate color pattern between T. infernalis and T. pompiliformis were collected in the same pitfall trap in a Cerrado area in Mato Grosso State, Brazil (PRB pers. obs.). This could mean that T. sancta, T. infernalis and T. pompiliformis are all a single moderately variable species. However, we refrain from formally synonymizing all of these species without further intermediate forms between the males, more distribution data and / or molecular data supporting the sex association.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD36BFF893F142FE24280FB7B.taxon	discussion	Remarks Traumatomutilla quadrinotata is perhaps one of the most common and easily identifiable species in the Brazilian Atlantic Forest. The sex association was based on the reliable color pattern of males and females of the Atlantic Forest species, which has been used as a basis for sex association in various species in the region (e. g., Bartholomay et al. 2020, 2021). The males of T. quadrinotata and T. tetratrauma sp. nov. are remarkably similar in coloration and external morphology, differing only in the length of the setae at the apex of the cuspis. Therefore, associating sexes for T. quadrinotata was only possible after the discovery of T. tetratrauma and its similarities with T. incerta (detailed in the remarks of T. tetratrauma). Although it is common for some specimens to completely or partially lose some of the body setae, the conspicuously long erect pronotal setae on the females of T. quadrinotata seems to be a consistent and exclusive character for this species (PRB & KAW pers. obs.). The males here associated with T. quadrinotata have been frequently misidentified as T. infernalis in the past, but true T. infernalis are absent from the Atlantic Rainforest region and differ from the male here associated with T. quadrinotata by many characters, most notably the lateral propodeal setae (dense and golden in T. quadinotata, sparse and black in T. infernalis).	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD370FF813CFA2D994241FCCC.taxon	discussion	Remarks After the sex association and synonymies of T. incerta were recognized, the only species found in the Amazon, particularly the Southeastern Amazonian areas were T. quadripustulata, Mutilla pruinosa and T. maraca. The types of M. pruinosa and T. maraca are identical in external and genitalic morphology. They have been repeatedly collected in the same areas as females of T. quadripustulata. As the two largest Traumatomutilla females with almost entirely black setal coloration, T. chrysozona (formerly T. lugubrina) and T. quadripustulata were easily mistaken for one another. Previous researchers separated T. chrysozona from T. quadripustulata mainly using T 2 spot color: yellow in T. quadripustulata and reddish in T. chrysozona. The T 2 integumental spots in T. quadripustulata, however, vary greatly in size and color. Various easily overlooked features are now recognized to differentiate these forms. First, T. quadripustulata females have a post-mesonotal tubercle that is usually associated with a slenderer and more elongate mesosoma than females of T. chrysozona. The most consistent setal features are the always present, though often inconspicuous, silvery-white setae patches on the metasoma of T. quadripustulata, compared against the rarely present and usually reduced coppery setae patches on the fringes of T 2 – 3 in T. chrysozona. Finally, true T. quadripustulata specimens have been found only in southeastern Amazonian areas, while T. chrysozona has a more southern distribution predominantly in eastern Cerrado areas of Brazil. In both of these species, T. chrysozona and T. quadripustulata, females are much darker in coloration than males, and they possess fewer pale setal markings than any other females in the T. quadrinotata species-group. Counter-intuitively, males of these species often have more extensive and distinct pale colored species than most other males in this species-group, with some males of T. quadripustulata almost completely lacking any black setae on the body. Sexual dimorphism in setal color patterns is common in velvet ants but, in most cases, the female pattern is the one with more extensive pale setal markings.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD378FF853F152AEB42FAFB9F.taxon	discussion	Remarks Based on distribution T. sancta is another species that could potentially be associated with T. pompiliformis or T. infernalis, though we refrain from doing so at this point due to the lack of any other putative males for T. austera, T. funebris, or T. ursina (see also remarks of T. infernalis). These also partly overlap in distribution with T. pompiliformis. The color pattern and distribution of T. sancta is typical of the dry savannah like areas of Cerrado and Caatinga in Midwestern and Northeastern Brazil, which is why the record from Venezuela is likely to be mislabeled. Aside from the integumental spots of T 2, there are no differences between T. sancta and T. solemnis. There are, however, no obvious intermediate forms between the relatively short and subrectangular spots of T. sancta and the elongate linear spots of T. solemnis. We have, however, seen examples of similar patterns forming a continuum between various species of Traumatomutilla, such as T. parallela (Klug, 1821) from the T. indica species-group (PRB & KAW pers. obs.).	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD37CFFFB3C9A2D3D4615FC20.taxon	discussion	Remarks Initially, T. quadrinotata appeared to be an easily recognizable, but variable species. It was originally known from females only and there seemed to be variation in the head setae color and mesosomal setal length. The male was also apparently easily recognized, based on its large body size, overlapping distribution, and parallel coloration with the female and other Atlantic Forest species. After careful examination of numerous suspected T. quadrinotata males, however, we discovered that there were two species with identical coloration and remarkably similar external morphology, but distinct genitalia (Figs 13 A – F, 19 A – F). Since there were two distinct species among the putative males of T. quadrinotata, we re-evaluated the species limits of the females. Those individuals with golden setae on the frons and uniformly short mesosomal setae were found to differ from the typical T. quadrinotata by structural features as well, namely the occipital carina was swollen, the scutellar area was armed with distinct anterolateral transverse carinae, and T 1 was slightly broader and shorter. We therefore recognized these females as belonging to a distinct new species, named here as T. tetratrauma sp. nov. The next step was to determine which of the males (short cuspis setae or long cuspis setae) belonged to each species. Both of these males and females overlap in distribution in the Atlantic Forest, so distribution couldn’t solve the association. Among the members of the species-group, only two males have short cuspis setae: T. incerta and one of these males. Therefore, the female of the short cuspis male should be similar to T. incerta. Traumatomutilla incerta and T. tetratrauma are the only species in this group with the occipital carina swollen and T 1 comparatively short and broad. We therefore hypothesize that the male of T. tetratrauma is the one with short cuspis setae. The male with longer cuspis setae is associated with T. quadrinotata. Given the similarities between these two species, various collections will likely have numerous specimens of T. tetratrauma sp. nov. misidentified as T. quadrinotata. Perhaps when these specimens are re-evaluated, patterns about their distribution will become clearer. At this moment, it appears that T. tetratrauma is a Northern species, with most records focused in Espírito Santo State. Conversely, T. quadrinotata seems more widespread with many records from São Paulo and Santa Catarina states.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD302FFFE3F152ACF42D7FDF0.taxon	description	Description Female BODY LENGTH. 16 – 17 mm. HEAD. Posterior margin almost straight. Occipital carina evenly arched and equally wide throughout. Vertex width 0.8 × pronotal width. Eye almost circular, its length in frontal view 0.9 × distance from its ventral margin to mandibular condyle. Head densely and coarsely foveolate-punctate to areolate-punctate. Genal carina poorly defined, nearly vestigial. Mandible elongate, oblique, tapering slightly towards with small subapical tooth. Dorsal scrobal carina present, well defined, disconnected from antennal tubercles and lateral scrobal carina. Antennal tubercle coarsely and irregularly rugose. Flagellomere 1 3.1 × pedicel length; flagellomere 2 2.0 × pedicel length. MESOSOMA. Length 0.9 × width. Mesosomal dorsum mostly concealed by dense setation, densely and coarsely areolate-punctate with apparent scabrous intervals medially where visible. Anterior surface of propodeum defined, short, slightly shorter than pronotal collar, coarsely striated longitudinally throughout with dense coarse punctures dorsomedially; dorsal surface rounded into anterior surface in lateral view. Humeral carina welldefined, projected dorsally, broadly separated from conspicuously projected angulate epaulet; anterolateral corners of pronotum sharply angulate in dorsal view. Pronotal spiracle slightly projected from lateral margin of pronotum, rounded, bulging. Lateral surface of pronotum sparsely punctate with dense micropunctures except at smooth conspicuous subacute tubercle anterior to pronotal spiracle; mesopleuron densely micropunctate anteriorly, sparsely and vestigially punctate to foveolate-punctate to areolate-punctate ventrad on mesopleural ridge; dorsal half of mesopleural ridge simply micropunctate; metapleuron unsculptured, smooth shining on dorsal fourth, densely, coarsely and confusedly areolate on basal fourth, and with concealed by dense setation elsewhere. Lateral surface of propodeum sparsely and coarsely foveolate-punctate posterad; smooth and shining anterad; with vestigially rugose intervals posterad. Ratios of width of humeral angles, pronotal spiracles, widest point of mesonotum, narrowest point of mesonotum and propodeum posterior to propodeal spiracles, 70: 77: 77: 56: 53. Lateral margin of mesonotum 217 conspicuously constricted anterior to propodeal spiracle, strongly diverging anterad, medially projected, into short, inconspicuous blunt process; with very small conspicuous tubercle posterior to lateral process. Propodeal spiracle strongly projected from lateral margin of mesosoma; post-spiracular area vestigial. Scutellar scale present, reduced, as narrow as surrounding sculpture; anterolateral carinae absent; scabrous intervals present on scutellar area. Propodeum slightly elongate, dorsal surface longer than and poorly distinguished from posterior surface. METASOMA. Ratios of width of T 1, width of T 2 and length of T 2, 41: 84: 84. Disc of T 2 mostly concealed by dense setation, densely and coarsely foveolate-punctate to punctate with dense, interspersed micropunctures where visible; foveolations sparser and micropunctures absent laterally and over integumental spots; anterolateral corners of T 2 devoid of setae and sculpture, smooth, shining. T 3 – 6 sculpture, except pygidial plate, predominantly concealed by dense setation, densely and coarsely foveolate-punctate to simply punctate with interspersed micropunctures where visible. S 1 sparsely, coarsely and confusedly foveolate-punctate, surface cuneiform, ending in short blunt longitudinal carina, slightly higher medially. S 2 sparsely foveolate-punctate, sculpture conspicuously sparser posteromediad; anteromedial crest-fold vestigial. S 3 – 4 sculpture mostly concealed by dense setation, densely and finely foveolate-punctate with sparse micropunctures where visible; S 4 densely foveolate-punctate; S 6 sparsely foveolate-punctate. Pygidial plate subpyriform, defined by lateral carinae at apical fourth of plate; surface irregularly rugose; interstice apparently granulose. Coloration and variations Integument black, except antennal flagellomeres and mandibles partially reddish-brown. Body setae predominantly and very densely black to brownish-black, except the following areas with silvery-white to silvery-golden setae varying in density: mesonotum, scutellar area, and propodeal dorsum laterally; mesopleuron, metapleuron, and lateral surface of propodeum; T 1 laterally, lateral felt lines of T 2, lateral margins of T 2, lateral areas of T 2 disc, fringe of T 2 – 4, fringe of T 5 medially, S 1 – 3, and fringe of S 2 – 3.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.

102A879CD302FFFE3F152ACF42D7FDF0.taxon	discussion	Remarks Traumatomutilla ursina is unusual, especially due to the conspicuously long brownish dorsal setae and the asetose and unsculptured anterolateral portion of T 2. Both these characters are unprecedented in South American Dasymutillini. Additionally, the head in frontal view seems to be wider than most Traumatomutilla species, especially related to how protuberant the eyes appear to be in frontal view. No structural or color variations were observed in the few specimens available for study, which, save for the specimen from Araxá (DZUP), have no other indication of locality except country and / or state. As mentioned before, T. ursina is one of four putative females that may be associated with either T. infernalis or T. pompiliformis.	en	Bartholomay, Pedro R., Williams, Kevin A., Cambra, Roberto A., Lopez, Vinícius M., Oliveira, Marcio L.
