Neocorynura centroamericana Smith-Pardo, 2005:166–170 ; species description: photograph of holotype (female) figure 1, page 167; distribution map on figure 2b, page 169.

Diagnosis. The males of this species can by recognized from other males by the following combination of characters: clypeus metallic green but with margins black ( Fig. 7 c), punctate and faintly imbricate, face above antennal toruli dark brown ( Fig. 7 c); mesoscutum dark brown with margins dark metallic green ( Fig. 7 d); metasomal T1 smooth and with coarse punctures, separated by 0.5–1.0 PD in between ( Fig. 7 f); T2 with basal third punctate as in T1 but with posterior two thirds densely punctate and punctures much smaller (half or less the diameter of coarser punctures on the base of T2) Fig. 7 f. The male of this species can also be distinguished from males of similar species, such as N. fumipennis (Friese) , by the following characters; mesoscutum faintly imbricate (strongly imbricate in the later) with coarse punctures, larger than those on T3 (smaller and similar to those on T 3 in the later) and separate by 0.5–1.0 PD in between along mid line (densely distributed elsewhere in N. fumipennis ). Males of N. centroamericana can also be separated from similar species by the sculpturing of T1 smooth with coarse punctures separated by 0.5–1.0 PD in between and T2 with basal third with coarse punctures and posterior two thirds with smaller punctures (one third of the diameter of basal ones) all densely distributed (distance between them ≤ 0.5 PD); sculpturing of T1 and T 2 in males of N. fumipennis and N. cribrita Smith-Pardo is mostly smooth but with few broadly scattered punctures, all with similar diameter.

Description. Male [ Fig. 7 . See description of the female in Smith-Pardo (2005a)]: as described for the female except as follows: Body length 11.0 mm; forewing length 6.4 mm. Head width 2.21 mm, length 1.99 mm. F2 longer than F1, but shorter than F3. Mandible slender and pointed and without preapical teeth. Labral surface smooth. Mesoscutum slightly wider than long. Basitibial plate absent; inner metatibial spur almost one-fourth the length of metabasitarsus, rather slender and serrated. Hamuli with a spacing pattern 3–1–1–4. Basal area of propodeum broadly sulcate ( Fig. 7 e). Metasoma with a slightly more elongate appearance ( Fig. 7 b); S6, S7, S8, and genital capsule as in Fig. 8 .

Mandible without grooves on outer surface, slightly carinate along posterior margin, anterior margin continuous. Subantennal and lower ocular areas densely punctate. Mesoscutellum with coarse punctures separated 0.5–1.0 PD along mid line and densely distributed elsewhere. Posterior side of propodeum with coarse punctures.

Clypeus and frons to the level of antennal insertion metallic dark green, margins of clypeus and rest of frons black ( Fig. 7 c); paraocular areas dark brown with metallic glare. Tegula dark brown ( Fig. 7 d). Legs uniformly dark brown ( Fig. 7 a,b). T1–T5 with basal metallic green to blue bands covering two thirds on T1, one third on T2, one fourth on T3 and between one fifth to one sixth on T4 and T5.

Mandible with some coarse, light brown, unbranched setae, 0.5–1.0 OD in length. Labrum mostly bare. Postgena with some long setae (0.5–1.5 OD in length) more sparsely distributed. Metanotum in general with longer setae (0.5–2.0 OD) along posterior margin, but with minute setae on anterior margin. Legs (especially hind ones) in general less pubescent; protrochanter with some light brown, branched setae minute—1.0 OD in length scattered on the posterior margin; profemur with white setae, 0.5–1.0 OD in length on surface; protibia less densely covered with dark brown setae; mesofemur with most of the inner side bare; metatrochanter densely covered with whitish setae on posterior margin; metafemur with some clear, 1.5–2.0 OD setae minute—1.0 OD in length setae, sparsely distributed on posterior margin. Metasomal pubescence as in the female except T1 with clear setae, 1.5–2.0 OD in length arising from each puncture, shorter setae along posterior margin, T2 with white setae sparsely distributed over basal metallic band, rest of its surface densely covered with minute, dark brown setae and with some longer setae (0.5–1.0 OD) scattered among the smaller ones; sterna with less pubescence, setae more scattered on S1–S3.
