Type data: Type male British Museum (Natural History), no. 18181. Type locality: “St Domingo”. Bequaert, 1928, (10)2: 162. Giordani Soika, 1941 , 2: 223. Eumenes abdominalis var. picta de Saussure, 1875 , 254: 107. Dalla Torre, 1894, 9: 17; Dalla Torre, 1904, 19: 20. Distribution: Haiti ; Dominican Republic ( Pedernales ; Santiago ). Comments and diagnosis: Eumenes pictus Smith, 1857 ( Fig. 16 ) resembles E. cubensis , but is separated from it by the following features: weaker punctation on mesosoma; T1 longer and slender, without evident punctation, as on T2. As we did not examine the type specimen, we based the redescription on five females and 4 males present at AMNH and UCD. Color, head: Black, with yellow marks as follows: mandibles; labrum; clypeus (except for brownish marks on basal region); inter-antennal region; a band on inner margin of compound eye, from the base of clypeus to the ocular sinus; a band on upper half of gena, adjacent to the compound eye. Scape predominantly yellow with brownish marks. Pedicel and the basal and the last flagellomeres brownish. Others blackish. Mesosoma: Black, except for the marks as follows: broad yellow band on anterior portion and a narrow one along the posterior edge of pronotum. Triangular brownish mark on posterior half of it. Wide yellow (with small brownish mark) on upper and basal half of mesepisternum, adjacent to the mesepimeron. Brownish with small yellow marks on each side of mesoscutum; tegula brownish-yellow; parategula yellow. Upper half of scutellum yellow, basal half brownish; metanotum entirely yellow. Wide yellow marks on each side of posterior face of propodeum, with small brownish bands adjacent to it. Coxae and trochanters black; femora with black (basal region), brownish and yellow (apical region) bands, respectively. Tibiae and tarsi yellow. Wings: Hyaline, with pterostigma, costal, medial and submedial cells yellow. Veins also yellow but becoming dark towards apex. Pubescence, head: Frons and vertex with moderately long golden pubescence. Gena and clypeus with short golden pubescence. Scape with very short golden pubescence. Mesosoma: Dorsal surface of pronotum, scutellum and metanotum with short golden pubescence. Posterior face of propodeum with slightly longer whitish pubescence. Lateral surface of mesosoma with short and whitish pubescence. Basal half of fore femur with scattered golden and moderately long bristles. Metasoma: Covered with very short (as on mesosoma) golden pubescence, except for some erect bristles on ventral face of T1 and apex of subsequent segments. Surface of integument, head: Clypeus with reduced punctation, hard to observe due the yellow color. Frons with evident punctation, moderately dense, becoming reduced towards vertex. Gena without evident punctation. Mesosoma: Covered with weak but evident and moderately dense punctation, except for anterior and posterior surface of mesepisternum, which is reduced. Metasoma: T1 and T2 with reduced puncation. T3–T6 and S2–S6 without evident punctation. Structure, head: Clypeus convex, longer than wide. Apex concave, forming two rounded projections with weak carinae on apex of each one. Inter-antennal region slightly wider than the antennal socket, longitudinally cariniform; lateral ocelli closer to the compound eyes than to each other; occipital carina well developed, angled on middle region of gena and distant to the compound eye near the mandible. Mesosoma: Pronotal carina present dorsally and laterally; pronotal fovea present; humeral region with pointed projection, as in genus Zeta ; posterior projection of tegula weakly developed, rounded; parategula lamelliform; lateral carina on upper half of the external face of fore coxae short and weak; concavity on posterior face of propodeum weakly developed. Metasoma: T1 slender, more than four times longer than wide ( Fig. 36 ), weakly swollen in dorsal view; T2 longer than wide ( Fig. 52 ), with the lateral margins moderately concave. Basal angle of T2, in lateral view, rising up about 45° regarding S2 axis. Apex of T2 with an apical lamella which becomes reduced towards apex. Male: Clypeus narrower than females; F11 short, basally broad and apically pointed, surpassing the apical edge of F8 ( Fig. 86 ). Dorsal surface without the longitudinal carina. Ventral surface with microscopic erect bristles. S7 flattened apically. Punctation on T1 and T2 more evident than on females. Pubescence as on females. Male genitalia: Aedeagus as in figure 102a, b. Like in E. cubensis , the lateral projections from the apex are distant from each other. Apical projection pointed ( Fig. 102b ). Paramere ( Fig. 102c ) with long bristles on middle area of gonostyle; digitus very modified, without the narrow apical projection (fig. 119), different of E. cubensis , E. americanus , E. smithii and E. belfragei , with scattered short bristles. Cuspis with erect bristles longer than on digitus. Volsella with scattered short bristles, as long as on digitus. Distal lobe strongly projecting, rounded on apex, with some erect bristles on basal region of it.
