Comments and diagnosis. We did not examine the type specimens of Eumenes versicolor , therefore we based the redescription of the species on the lectotype of E. fulvomaculata .

Eumenes versicolor can be identified by the following features: body predominantly black with well developed marks mainly on mesosoma; clypeus with weak punctation, less evident than in E. rufomaculatus (fig. 76); humeral region more projecting than E. filiformis . T1 very long and narrow; apical region from the ventral surface of T1 ventrally projecting. Digitus broad in basal half, becoming narrow towards apex (fig. 125), with the dorsal edge weakly angled (not strongly as on E. filiformis ). Digitus with short bristles along the dorsal edge, while there are scattered short bristles on the broad region (more evident than in E. rufomaculatus ).

Redescription of the lectotype of Eumenes fulvomaculata Fox, 1899 (fig. 26)

Female. Color, head: Black with yellow marks as follows: apical half of mandibles; labrum; clypeus and inter-antennal region and slightly above it; a longitudinal stripe on apical half of gena, adjacent to the compound eyes; basal region of scape and part of pedicel and flagellum, while F8–F10 are predominantly yellow. Mesosoma: Dorsal surface of pronotum yellow with a small black spot near pre-tegular carina, while the anterior face and the region below humeral region entirely black; mesepimeron and mesepisternum black, except for a big yellow spot on the apical half and center region; mesoscutum black, with a triangular shape yellow mark on each side of it; tegula black with yellow mark on anterior and posterior regions. Yellow marks as follows: parategula; scutelum, except for a blackish triangular shape on basal half; metanotum; dorsal face of propodeum, except for a longitudinal broad stripe on middle region; posterior half of lateral face of propodeum, while the anterior is blackish. External face of coxae yellow, while inner face is blackish; trochanters black; external face of fore and hind femora yellow, while inner face and entirely hind femur are black; entirely fore tibia and part of mid tibia yellow and just a spot on apical region of hind tibia; entirely fore tarsus yellow; mid tarsus also yellow, except for the Ts5 blackish; entirely hind tarsus blakish. Metasoma: T1 black, except for the yellow regions as follows: longitudinal stripe along the lateral face (except the basal region), which continue up to a transverse stripe on apex region. Ventral face of T1 darkened, brownish-ferrugineous. T2 black, except for a transverse stripe on apex, which extends to the lateral face, where there is a big yellow spot on the middle region. Some shining brownishferrugineous marks on lateral face, between the big yellow spot and the apical stripe. Apical lamella of T1 yellow. S2 yellow, except for the blackish basal region. T3–T6 and S3–S6 entirely yellow. Wings hyaline, with the costal and medial cells slightly darker. Veins black becoming brownish towards apex.

Pubescence, head: Clypeus with short whitish (better observed in oblique view) pubescence. Frons, vertex and occipital region with long and golden pubescence, while on gena it is short (shorter than on clypeus). Scape with golden pubescence as short as on clypeus. Mesosoma: pronotum, mesoscutum, scutellum and metanotum with long golden pubescence (slightly shorter on pronotum and mesoscutum). Mesepisternum and posterior and lateral face of propodeum with whitish pubescence, longer on the latter. Trochanter and basal half of femur of the fore leg with erect golden bristles. External surface of tibiae also with golden and erect bristles. Metasoma: Covered with golden pubescence. Short pubescence on dorsal face of T1 and other segments. Ventral surface of T1 with scattered long bristles. Apex of the other segments with long bristles.

Surface of integument, head: Weak punctation on clypeus homogeneously distributed. Frons with coarse and moderately dense punctation; reduced punctation behind the ocelli and on gena. Mesosoma: Covered with coarse and moderately dense punctation as on frons, except on basal half of mesepisternum where it is sparser.

Metasoma: Dorsal surface of T1 with coarser and moderately dense punctation, becoming denser on apex. Lateral surface of T1 with scattered punctures, while ventral surface without evident punctation. Dorsal surface of T2 with coarse and dense punctation, becoming slightly weaker and sparser towards lateral surface. T3–T6 and S2–S6 without evident punctation.

Structure, head: Clypeus convex, longer than wide, with the apex concave forming two rounded projections with weak carinae on apex ( Fig. 76 ); inter-antennal area wider than the antennal socket, with a central tubercle; lateral ocelli closer to the compound eye than to each other; occipital carina angled on middle region of gena and close to the compound eyes next to the mandible. Mesosoma: pronotal fovea present; pronotal present dorsally and and more developed laterally; humeral region weakly projecting; mesepimeron slightly elevated regarding the mesepisternum; posterior projection of tegula weakly developed and rounded; parategula lamelliform; posterior face of propodeum strongly concave on basal half. Basal region of the external surface of fore coxa with a short and weak carina. Metasoma: T1 very long, more than five times longer than wide ( Fig. 42 ); T2 longer than wide, with the lateral margins weakly concave ( Fig. 58 ); apical lamella on apex of T2, becoming reduced towards lateral margins. Apical region of T2 (in lateral view) slightly elevated; S2 with a weak longitudinal elevation, better observed in oblique view.

Male: Clypeus and inter-antennal region slightly narrow. F11 long, without longitudinal carina, with the apex pointed, surpassing the apical edge of F8 and without microscopic bristles on ventral surface ( Fig. 92 ). Ventral face of S7 flat, with long bristles along the edge. Color, pubescence, surface of integument and other structure as in females.

Male genitalia: Aedeagus as in figure 108a, b. Paramere (fig. 108c) with long bristles on middle region of gonostyle; digitus flat dorso-ventrally, broad on basal half, becoming narrow towards apex (fig. 125), with the dorsal edge weakly angled. Short bristles along the dorsal edge of digitus, while on the broad region occur scattered short bristles. Cuspis with erect short bristles; distal lobe truncate, without bristles.

Type material: The lectotype of Eumenes fulvomaculata Fox, 1899 is in good condition and bears the labels: ‘Santarém’ ‘ Eumenes \ fulvomaculatus \ Types Fox’ ‘ LECTOTYPE ♀ \ Eumenes \ fulvomaculatus Fox, 1899 \ des.
