Comments and diagnosis: The type specimen of Eumenes consobrinus de Saussure, 1855, was not examined, but according to our study we confirm the type specimens of E. iturbide de Saussure, 1857, and E. globulosiformis Viereck, 1908, as synonyms of that species. The redescription here was based on an E. iturbide female. According to Giordani Soika (1978: 23), the type locality of E. consobrinus is unknown, although it was described from Brazil (“Le Brésil ”), but Giordani Soika noted that the locality is certainly wrong. Eumenes consobrinus and E. bollii are the only species that do not have a pronotal carina on the dorsal face of the pronotum. However, the former species can be easily distinguished by the following features: integument predominantly black, with yellow marks mainly on clypeus, inter-antennal region, dorsal face of pronotum, mesepisternum, metanotum, and apex of T1–T6; long pubescence along body, mainly on scape, frons, occipital region, mesosoma, and T1; coarse and moderately dense punctation on frons, vertex, dorsal surface of mesosoma, mesepisternum, and posterior face of propodeum; dorsal face of T1 and T2 with punctation coarse but slightly sparser; T1 not swollen in dorsal view; and angle of the base of T2, in lateral view, rising up abruptly, with a sinuosity on the distal third of it. We examined all the type specimens of synonyms of E. consobrinus consobrinus (not the primary type of E. consobrinus) and E. consobrinus pedalis, and a total of 53 non-type specimens (27 females and 26 males, and all male genitalia were extracted and examined) identified as E. consobrinus and we conclude they are one species, although we found a range of intraspecific variation within the species. This leads us to propose E. pedalis Fox, 1894, E. crassicornis Isely, 1917, and E. pachygaster Isely, 1917, as synonyms of E. consobrinus. This variation is described below, along with the main reasons for these synonymies. Redescription. Holotype Eumenes iturbide, de Saussure, 1857 (Fig. 6) Female. Color, head: Black with yellow marks as follows: two small spots on basal portion of clypeus; a triangular sport right above the inter-antennal region; a small spot on upper half of the gena, adjacent to the compound eye. Brownish marks on apex and tooth of the mandibles and on apex of the labrum. Mesosoma: Black, with yellow marks as follows: small spot on humeral region; a stripe on center region of the dorsal face of the pronotum; entirely tegula; a broad transverse stripe on middle region of metanotum; small marks on distal region of femura; mostly tibiae and tarsi. Metasoma: Black with yellow marks as follows: transverse stripe on apex of T1- T4; spot on apex of T5 and T6; transverse stripe on apex of S2–S6. Wings: Hyaline, with costal, medial, submedial cells slightly yellowish; pterostigma darkened; veins brownish. Pubescence: Body covered with long and golden pubescence. Head: long pubescence on the basal half and sides of clypeus, becoming shorter on center and apex. Scape, frons, vertex, occipital region and gena with long pubescence. Gena with shorter pubescence. Surface of F1 and F2 (mostly external surface) with scattered and microscopic erect bristles. Mesosoma: Anterior face of coxae (mainly the fore coxa) and all mesosoma with long pubescence, slightly shorter than that on frons and occipital region. Anterior surface of mid and hind coxae with long pubescence but shorter than on fore coxae. Trochanter and basal half of fore femur with scattered erect bristles. Metasoma: T1 with long pubescence (as in mesosoma) on basal half that becomes shorter towards the apex; T2 with short pubescence (as on distal half of T1), although the first third of the sclerite the pubescence is slightly longer; T3–T6 and S2–S6 with short pubescence (as or slightly shorter than on distal half of T2), except for some long bristles on apex. Surface of integument, head: Clypeus with coarse and homogeneously distributed punctation; frons, vertex and gena with coarse punctation, on the first two regions moderately dense and on the latter sparser. Mesosoma: Covered by coarse and moderately dense punctation (as on frons), although on posterior face of propodeum it is denser, forming small carinae between each puncture. On anterior portion of the lateral face of the propodeum the punctation is reduced, almost absent. Metasoma: T1 with coarse punctation but sparser (as on clypeus); T2 with coarse and moderately dense punctation on basal half that becomes denser towards the pre-apical region, while on the apex (before the lamella) it becomes weaker and sparser. Laterally the punctation becomes weak and sparser. S2 with some coarse punctures on basal half becoming weaker and sparser towards apex. T3–T6 and S3–S6 with reduced punctation or at least some coarse punctures on T3 and S3. Structure, head: Apex of the labrum rounded; clypeus as long as wide with the apex concave and forming two projections with carinae on the apex of each one. Inter-antennal region wider than the antennal socket, pointed centrally, with a weak longitudinal carina from the tubercle to the basal suture of the clypeus, but not touching it. Lateral ocelli closer to each other than to the compound eyes; occipital carina complete, angled on middle region of the gena and very close to the compound eyes next to the mandibles. Mesosoma: Dorsal face of pronotum without pronotal carina, although it is present on the lateral face; pronotal fovea present; posterior projection of the tegula weakly developed, rounded; parategula flattened laterally, lamelliform; posterior face of the propodeum strongly concave on basal half. A carina on the basal half of the lateral side of the fore coxa. Metasoma: T1 at least three times longer than wide, not swollen in dorsal view (Fig. 30), slender, with the lateral margins of the distal half weakly concave and the lateral margins of the apex divergent. T2 as long as wide in dorsal view (Fig. 46), with an apical lamella well developed which runs until the lateral sides of the sclerite. In lateral view, the basal angle of T2 rises up abruptly (Fig. 59), turning into a strong concavity on the middle portion of it and then lowering again forming a clear sinuosity on the pre-apical region of the T2. Male: Clypeus narrower than females; F11 long, without longitudinal carina on dorsal surface, with the apex pointed surpassing the apical edge of F8 (Fig. 80). Ventral surface with microscopic bristles. S7 apically flat with moderately long bristles at the edge. Color, pubescence, punctation and structure (except for those cited above) same as in females, including the variation. Male genitalia: Aedeagus as in figure 96a, b. Two varying features found in the aedeagus were: the concavity of the posterior margin of the ventral lobe more or less strong, the same occurring in the middle region in dorsal view. Paramere (fig. 96c) with long bristles in the middle region of gonostyle; digitus long, becoming slender towards the apex, with moderately long bristles at the base and slightly shorter towards apex (fig. 113); long bristles on ventral edge of volsella and scattered short bristles; distal lobe truncate, without evident bristles; cuspis with scattered erect brist
