Male unknown
Diagnosis. Females of Neocorynura guarani can be easily recognized by its distinctive integumental color: uniformly metallic green. This species can be distinguished from N. pseudobaccha by the clypeus imbricate only along the margins, area adjacent to the internal margins of compound eyes yellowish, base of the propodeum uniformly sulcate, and metasoma metallic green (metallic red or orange in N. pseudobaccha).
Description: Female (Holotype). Body length 8.6 mm; forewing length 7.0 mm. Head width 1.9 mm, length 1.8 mm. Scape longer than combined lengths of F1 to F6; F10 longer than preceding flagellomeres; F1 slightly shorter than F2. Clypeus wider than long; paraocular lobe obtuse (≈ 120°). Mesoscutum slightly wider than long; metanotum more than half length of mesoscutellum. Mesotibial spur serrate and more than half length of mesobasitarsus; inner metatibial spur pectinate with 5 teeth, the last two slightly fused. Marginal cell semi-truncate; 1m-cu confluent with 1rs-m; 2m-cu basad 2rs-m by approximately 4 times vein width; first submarginal cell longer than combined lengths of second and third submarginal cells; second submarginal rectangular; anterior border of second submarginal cell as long as anterior border of third submarginal cell; pterostigma large, margin in marginal cell convex; hamuli spaced 3-1-1-2 along anterior margin of hind wing. Basal area of propodeum sulcate and longer than mesoscutellum. Metasoma semi-petiolate (slightly longer than wide).
Labrum slightly striate, with small, more or less narrow central process. Clypeus imbricate along margins, smooth elsewhere, with very coarse punctures separated by 1–2 PD; supraclypeal area imbricate with punctures separated by 1 PD; subantennal and lower ocular areas imbricate; frons and remainder of face with smaller and more numerous punctures, integument between punctures strongly imbricate; vertex sculptured as frons; gena and postgena smooth with small, faint punctures and striate. Scape imbricate, with minute punctures separately by about 0.5–2 PD. Pronotum mostly smooth or faintly imbricate; propleura striate and imbricate. Mesoscutum densely punctate, punctures coarse and separated by less than 1 PD, integument between punctures strongly imbricate; mesoscutellum smooth and punctate, punctures of different diameter. Metanotum smooth, densely punctate, punctures small. Pleura strongly punctate with a rugose appearance, integument between punctures strongly imbricate. Tegula faintly imbricate. Basal area of propodeum sulcate and smooth on anterior margin and imbricate on posterior end.
Mandible dark brown, tip hyaline. Labrum black; clypeus metallic green with anterior margin dark brown and with yellow reflections; remainder of head metallic green. Mesosoma and metasoma metallic green, except for posterior margins of T1–T5 with posterior margins dark brown.
Mandible with brown, unbranched setae, 0.5–1.5 OD in length, scattered. Labrum mostly bare with a row of coarse, brown, unbranched setae along anterior margin. Clypeus with light brown and branched setae, minute— 0.5 in length, sparsely distributed over surface and with a row of coarse, unbranched setae, 1.0 OD in length forming a row over anterior margin; some minute setae present on lateral margins and close to compound eyes. Supraclypeal area as on clypeus; subantennal area and frons with light brown, minute branched setae more or less densely distributed and with some sparse dark brown, poorly branched setae 0.5 OD in length among the lighter ones. Scape mostly with minute brown, poorly branched setae sparsely distributed few longer setae (0.5 OD) close to scape base. Vertex as on frons, except for some coarse, light brown setae sparsely distributed; gena with minute, white setae densely distributed; postgena with light brown, branched setae, 0.5–2.5 OD in length scattered. Pronotum densely covered with minute, brownish setae with some coarse, darker and branched setae among them. Mesoscutum with minute, white setae more or less densely distributed. Mesoscutellum as mesoscutum, except for some coarse, dark brown, poorly branched setae, 0.5–2.0 OD in length sparsely distributed between the white setae. Metanotum more densely covered with minute, white setae and longer (0.5–1.0 OD), branched setae, mostly along sides. Base of propodeum mostly bare, rest of surface with minute, light brown setae, densely distributed on posterior sides, longer setae (1.5 OD) close to spiracles. Preepisternum and mesepisternum with coarse, light to dark brown setae, 1.0–1.5 OD in length, scattered among minute, whitish setae; metepisternum densely covered with minute, whitish setae. Procoxa with coarse, dark brown setae, poorly branched, and 1.0–1.5 OD in length scattered among minute, light brown ones; protrochanter mostly bare but with some coarse, light brown, unbranched setae, 1.0–3.0 OD in length along posterior margin mixed with some minute, light brown setae; profemur with outer side mostly covered with light brown, poorly branched setae, sparsely distributed and 0.5–2.0 OD in length (longer ones close to trochanter), inner surface more densely covered with minute, whitish setae; protibia with outer side mostly covered with minute light brown setae, densely distributed, inner surface more densely covered with longer setae (minute—1.0 OD); tarsi as in protibia; mesocoxa covered with minute, whitish setae, with few coarse, light brown, unbranched setae, 1.0–2.0 OD in length close to articulation with mesotrochanter; mesotrochanter with light to dark brown, unbranched setae, 0.5–2.0 OD in length mixed with some minute, light brown setae; mesofemur inner side with coarse, light brown setae, 0.5 OD in length and densely distributed in anterior angle and forming a patch, rest of surface with coarse, dark brown, poorly branched setae, minute—2.0 OD in length, sparsely distributed; mesotibia densely covered with unbranched setae, minute—0.5 OD in length, those on posterior margin dark brown on base and white on tip; mesotarsi as protarsi; metacoxae as procoxae, except setae more abundant and light brown, 0.5– 1.5 OD in length; metatrochanter more or less densely covered with coarse, dark brown, branched setae, 0.5– 1.0 OD in length; metafemur with coarse, dark to light brown setae, long (some as long as 3.5 OD) somehow bending and forming scopae; metatibia sparsely covered with coarse, darker setae, those in anterior margin 1.0–1.5 OD in length, sparsely distributed, and with 3–4 branches mostly on tip, rest of surface with coarse, dark brown or white, unbranched setae, more or less densely distributed. T1 with coarse, white, branched setae, 1.0–2.5 OD in length and sparsely distributed; T2 and T3 densely covered with minute, light brown setae, with some coarse, dark brown, unbranched setae sparsely distributed; T4 as T2 and T3 except, darker setae more abundant and almost 1.0 OD in length; T5 densely covered with coarse, brown setae, minute—2.5 OD in length, some branched and sparsely distributed among unbranched ones, lateral region with longer ones (1.5–2.0 OD).
Type material. Holotype. Ƥ, PARAGUAY: Caaguazu, Pastoreo, N.E. Coronel Oviedo. I-5-1972. L. Peña Coll. (AMNH)
Paratype. Same label data as in the holotype (1 Ƥ AMNH). Unfortunately, this specimen is missing the head, nonetheless since this is the only known specimen aside from the holotype, it is designated paratype of this newly described species.
Etymology. The specific epithet honors the Guarani Indians; a group of culturally related indigenous people of South America, whose original distribution included most of Paraguay, the only country where the species is known to occur.
