Closterocerus cinctipennis Ashmead, 1888:4 . Neotype female CNC, examined. Designated by Hansson (1994:4),

Chrysonotomyia baliosa Yoshimoto, 1980:1042 . Holotype female CNC, examined. Synonymy with C. cinctipennis by Hansson (1994:4).

Chrysonotomyia cunicularia Yoshimoto, 1980:1044 . Holotype male in USNM, examined. Synonymy with C. cinctipennis by Hansson (1994:4).

Diagnosis. Antenna with F1–3 flattened and F4–5 less flattened, scape widest just below apex ( Fig. 68 ); ocelli very small, ratio POL/posterior ocellus width 3.7 ( Fig. 67 ); pronotal collar without a carina along anterior margin ( Figs 65, 67 ); midlobe of mesoscutum with two pairs of setae ( Fig. 67 ); fore wing hyaline with three infuscate parts: along apical margin, below stigmal and marginal veins ( Figs 66, 67 ); hind tarsus predominantly white (T4 sometimes infuscate) ( Figs 66, 68 ); length of body female 0.8–1.0mm.

Description (Mexican specimens). Length of body: 0.8–1.0 mm.

Antenna dark brown. Frons golden-green below frontofacial suture and golden-purple above suture. Vertex metallic blue with purple tinges. Mesoscutum with midlobe metallic blue, sidelobes metallic purple. Mesoscutellum, dorsellum and propodeum metallic purple. Legs with coxae, femora and hind tibia dark brown, fore and mid tibiae dark brown in basal one-half and white in apical one-half; fore tarsus infuscate, mid and hind tarsi white. Fore wing hyaline with three infuscate parts: along apical margin, below stigmal vein and below marginal vein; hind wing hyaline. Petiole dark brown. Gaster dark brown with metallic purple tinges.

Antenna predominantly flattened, F4–5 less so. Frons below frontofacial suture with weak reticulation, above suture with strong reticulation. Vertex with strong reticulation. Frontofacial suture V-shaped. Subtorular sutures present. Occipital margin rounded.

Pronotal collar without a carina along anterior margin. Mesoscutum with strong reticulation; notauli distinct ±throughout; midlobe with two pairs of short setae. Mesoscutellum with weak reticulation. Dorsellum convex with weak sculpture. Propodeum smooth, without median carina; callus with two setae. Fore wing speculum closed; with a stigmal hairline and with radial cell bare.

Petiole very short, just a transverse strip. Gaster ovate; tergites with weak reticulation.

Relative measurements: head length dorsal 12; head length frontal 14; head width 23; POL 5.5; OOL 2; lateral ocellus maximum width 1.5; eye length 11; malar space 4; mouth width 6; mesosoma length 24; mesosoma width 19.5; mesoscutellum length 11; mesoscutellum width 12; fore wing length 37; fore wing width 22; marginal vein length 19; postmarginal vein length 1.5; stigmal vein length 3; fore wing marginal fringe length 6; gaster length 27; gaster width 21.

Variation in paratype material. Body length 0.8–1.0mm.
