Mesoscutum and scutellum posteriorly with yellow bands, pronotum often with anterior band weakly indicated in middle. POL about 1.3‒1.4× OOL; inner margin of the eyes emarginate; clypeus apically bilobate, without a conspicuous median tooth; pronotum without premarginal carina; dorsellum convex, margin carinate, moderately pilose; propodeum pilose, median carina present, plicae absent; hind coxal depression uniformly punctate, with a conspicuous translucent lobe dorso-laterally; hind femur about 2.2× as long as broad, teeth excluded; fore wing with apical fifth infuscate and apical process of stigmal vein about 0.8× as long as uncus; in female, tergite I with median ridge and diverging broad furrows; tergite VI with spiniform projection at posterior margin, below spiracle level; ovipositor reaching the dorsellum; in male, gaster petiolate, tergite I with yellow band, and two more narrow yellow bands on the carapace in dorsal view; in lateral view, tergite VI oblique relative to tergite V. Description (Male, pinned). Head as broad as pronotum posteriorly, dorsally 2.5× as broad as long; temples half the longest breadth of median ocellus. Occipital carina high at ocellar region, dorsally complete, extending laterally to apical third of eyes height in lateral view. POL about 1.34× OOL, ocellar triangle 2.85: 1 (length: height); lateral ocelli touching occipital carina. Vertex densely punctate-reticulate, except for a smooth depression from posterior margin of median ocellus to scrobes. Scrobes not touching median ocellus; scrobal carina dorsally slightly raised. Frontal view, head 1.38× as broad as high; face finely vertically rugulose-punctate, with sparse white pubescence. Malar space 0.26× eye height in lateral view; glabrous adjacent to eye, vertically aciculate, with few sparse hairs. Clypeus in frontal view 0.85× as high as broad, 0.5 as broad as mouth, apically bilobate, without a median tooth. Mandibles with slender tooth separated from the upper border by narrow and shallow triangular notch. Occiput in posterior view concentrically rugulose-punctate. FIGURE 18. Leucospis opalescensA .

Hind leg, lateral view. Scale bar = 1 mm. UFMG–IHY–1305653 Mesosoma dorsally with short pubescence. Pronotum and mesoscutum punctate-reticulate, with punctation very dense and transversely confluent, with transverse microsculpture, which is more evident on mesoscutum; scutellum punctate-reticulate, with very subtle longitudinal microsculpture. Pronotum without discal and premarginal carinae; posterior margin slightly concave, carinate centrally; lateral panel concave, its lower corner broadly rounded. Mesoscutum, in lateral view, bowed; notaulus absent. Tegula broadly smooth, with pale yellowish pubescence. Scutellum evenly convex in lateral view, 0.8× as long as maximum breadth in dorsal view. Dorsellum 3× as broad as long medially, margined with narrow upturned carina, alveolate along margin. Propodeum medially 2.24× as long as dorsellum; punctate-reticulate, posterior margin alveolate; median carina raised and thin, plicae present only anteriorly. Mesepisternum rugulose-punctate; subalar area and mesepimeron punctate, the latter with oblique microsculpture; mesopleural depression smooth, except for punctate antero-ventral region; anterior border with sparse pilosity. Legs. Upper edges of fore femur and tibia strongly carinate. Hind coxa uniformly punctate; upper edge evenly convex, posteriorly with a large triangular translucent lobe; with dense white pilosity directed to meso-external edge. Hind femur 2.17× as long as broad, excluding teeth; densely regularly punctate, with short dense white pubescence directed to ventral edge which has a basal tooth (basally broader than long) and 11 other teeth ( Fig. 19E ). Hind tibia densely finely punctate, apically oblique with a long sharp outer spur. Wings . Fore wing hyaline; slightly infumate along anterior and apical borders; uniformly pilose; veins light brown. Stigmal vein almost straight, forming an angle about 42° to R1; about as long as marginal vein. Uncus straight, directed towards apex of R1. Apical process of stigmal vein as long as uncus ( Fig. 18D ), rounded. Hind wing hyaline, sparsely pilose with glabrous regions basally; veins light brown. Gaster 2.5× as long as maximum width in dorsal view; punctation sparse on sternites and almost inconspicuous on tergite II. All tergites distinct, though third to sixth fused into a carapace, but indicated by much sparser punctation at posterior margins. Tergite I 0.8× as broad as long; 0.4× as broad as maximum breadth of metasoma; dorsally with deep small triangular basal fovea. Epipygium sligthly convex in lateral view, with distal margin convex; densely punctate; no longitudinal keels. Last two sternites shallowly depressed in the midline; last one apically rounded. Color. Body extensively black. Light brown on: scape, tegula, legs except tarsomeres. Yellow on: pronotum with tiny central spot and narrow transverse band posteriorly, interrupted centrally; posterior margin of mesoscutum; posterior margin of scutellum; entire dorsellum; posterior half of mesepisternum; dorsal edge and postero-ventral maculae on hind coxa; hind femur dorsal edge externally, ventral edge external and internally; posterior half of tergite I; entire sternite II; two lateral spots on sternite III; two yellow bands on carapace, at middle of tergites IV and V; two lateral spots on tergite VI, above the level of spiracle; green purple metallic shine scattered over entire body, although more evident in the face, mesopleuron and propodeum. Measurements. See table I. Distribution. Brazil ( Pará , Mato Grosso , Mato Grosso do Sul , Minas Gerais ) Comments. Leucospis opalescens is an endemic Brazilian species, which was previously recorded from the Amazon and Pantanal. The new records presented here extends its distribution southwestward to the Brazilian Savannah ( Figs 25 , 26 ). The presence of the lateral posterior projection of tergite VI in L. opalescens females ( Fig. 18J ) is a valuable character for differentiating it from females of L. signifera , a separation that was previously difficult ( Bouček, 1974a ).
