( Figs 6–9 View FIGURES 6 – 9 , 57 View FIGURES 56 – 68 )
Diagnosis. Scutellum with 2 pairs of setae, one anterior and one posterior ( Fig. 7 View FIGURES 6 – 9 ); pronotum with a weak transverse carina close to posterior margin ( Fig. 7 View FIGURES 6 – 9 ); frontal suture reaching eyes at a level equal with anterior margin of anterior ocellus ( Fig. 9 View FIGURES 6 – 9 ); forewing costal cell ventrally with a sparse row of setae in apical ½ (as in Fig. 51 View FIGURES 47 – 53 ).
Similar to D. quadrifer and D. apon except for height of frontal suture, weak pronotal carina close to posterior margin, distinct notauli in posterior 2/3 ( Fig. 7 View FIGURES 6 – 9 ), and propodeal callus with 7 setae.
Description. FEMALE. Length 2.1 mm. Scape pale brown with dorsal edge dark brown, pedicel and flagellum dark brown. Frons metallic bluish-purple with clypeal area golden-green. Vertex metallic bluish-purple. Mesoscutum, scutellum and propodeum metallic bluish-green with purple tinges, scutellum with posterior 1/5 metallic purple. Coxae dark and metallic; femora and tibiae dark brown; tarsi with tarsomeres 1–3 white, 4 dark brown. Forewing hyaline. Gaster with tergites 1, 2, 6 metallic bluish-green, remaining tergites dark brown with metallic tinges.
Antenna as in Fig. 57 View FIGURES 56 – 68 . Frons with raised, weak reticulation ( Fig. 6 View FIGURES 6 – 9 ); frontal suture reaching eyes at level equal with anterior margin of anterior ocellus. Vertex with engraved, weak reticulation ( Fig. 9 View FIGURES 6 – 9 ). Occipital margin rounded. Eyes with longer hairs and eye setation denser than in other species ( Figs 6, 9 View FIGURES 6 – 9 ).
Pronotum with a weak transverse carina close to posterior margin ( Fig. 7 View FIGURES 6 – 9 ). Mesoscutum with raised, strong reticulation ( Fig. 7 View FIGURES 6 – 9 ); notauli as narrow distinct grooves in anterior 1/3, and as wide but distinct grooves in posterior 2/3. Scutellum with raised, weak reticulation ( Fig. 7 View FIGURES 6 – 9 ), posterior margin smooth; with 2 pairs of setae. Propodeum with weak reticulation and irregular longitudinal carinae medially ( Fig. 8 View FIGURES 6 – 9 ); callus with 7 setae. Forewing speculum closed below; costal cell ventrally with a sparse row of setae in apical ½.
Petiole 0.4X as long as wide, smooth. Gaster elongate with apex acuminate; tergites smooth.
MALE. Unknown.
Material examined. Holotype female ( BMNH) labelled “ BRAZIL, Bahia Mucari, xi.1978, F. Benton”.
Etymology. Named for the (weak) pronotal carina, from the Greek ambon = carina, ridge.
