Material.

HOLOTYPE male (CNC) glued to a card, labeled "U.S.A.: Connecticut, New Haven Co., New Hamden, Lockwood Farm, 1.viii.1980, C.T. Maier", "Tentiform mine of Phyllonorycter propinquinella on Prunus serotina, emerged in laboratory within 3 weeks". PARATYPES: 1 female 3 males with same label data as holotype (BMNH, CAES, CNC)); 1 male labeled "U.S.A.: Connecticut, Tolland Co., Willington, 21.x.1981, Chris T. Maier", "Mines of Phyllonorycter propinquinella on black cherry, Prunus serotina, on 21.x.1981, chilled outdoors, parasitoid emerged in laboratory in April 1982" (CNC); 3 females "U.S.A.: Connecticut, New Haven Co., North Haven, 1.vii.1981, C.T. Maier", "Tentiform mine of Phyllonorycter nr crataegella on Prunus pensylvanica, emerged in laboratory within 3 weeks" (BMNH, CNC); 2 females 1 male from same locality and same host as previous but collected 2.vi.1986 (BMNH).

Diagnosis.

Both sexes: fore wing WIP with several distinct wide colourful cross-bands traversing the wing (Figs 64, 65), fore coxa white, hind coxa except apex golden green (Figs 62, 63); male: scape widest just below median part, with a single sparse row of setae along ventral margin (Fig. 59), antennal scrobes join frontal suture wide apart (Figs 67), vertex with long forward pointing setae (Fig. 69) - setae about as long as distance between posterior ocelli, upper frons without setae (Fig. 67), frons very large and wide (Fig. 67) - at its widest part 0.8X as wide as width of head; female: scape predominantly white and widest medially, with a single row of setae along ventral margin, propodeum smooth (Fig. 70), frons above frontal suture with raised and strong reticulation (Fig. 66).

Description.

Female. Length 1.1-1.5 mm. Scape white with inner apical tip infuscate; pedicel pale brown; flagellum dark brown (Fig. 58). Frons below frontal suture golden green to golden red, above frontal suture bluish green metallic (Fig. 56). Vertex inside ocellar triangle golden red, outside ocellar triangle golden green. Mesoscutum golden green with golden red areas - especially so in smooth posterior notaular depressions, to completely golden green (Fig. 60). Scutellum golden red with sides and posterior margin bluish green metallic, to completely golden green (Fig. 60). Propodeum golden red to golden green (Fig. 60). Fore coxa white, mid coxa dark brown with apical 1/3 white to completely dark brown, hind coxa golden green (Fig. 62); femora, tibiae and tarsi on all legs white. Wings without pigmented areas; WIP in fore wing with several distinct wide colourful cross-bands traversing the wing (Fig. 64). Gaster with first two tergites golden green, remaining tergites golden purple with green metallic tinges.

Antenna as in Fig. 58. Frons below level of toruli smooth and shiny (Fig. 66), between level of toruli and frontal suture with raised and strong reticulation lateral to antennal scrobes, between antennal scrobes with very weak reticulation, above frontal suture with raised and strong reticulation. Vertex inside ocellar triangle with engraved and weak reticulation, outside ocellar triangle smooth and shiny (Fig. 68). Occipital margin rounded.

Pronotal collar without transverse carina (Fig. 70). Mesoscutum with raised and strong reticulation (Fig. 70), meshes of reticulation smaller on sidelobes than on midlobe, midlobe with pits (i.e. with very strong reticulation) posteromedially; notauli as smooth impressions in posterior 2/3. Scutellum with very weak reticulation and shiny, smooth along posterior margin, with 3-4 pits medially on either side of imaginary median longitudinal line (Fig. 70). Dorsellum flat and smooth, anterolaterally with two foveae. Propodeum smooth and shiny (Fig. 70); propodeal callus with three setae. Fore wing speculum closed below. Petiole conical without shoulders.

Ratios. HE/MS/WM = 5.0/1.0/2.3; POL/OOL/POO = 2.6/1.1/1.0; WH/WT = 1.2; LW/LM/HW = 1.6/1.0/1.0; PM/ST = 1.0; MM/LG = 0.8-0.9.

Male. Length 1.4-1.5 mm. Scape and pedicel white; flagellum dark brown with golden green tinges (Fig. 59). Frons green metallic (Fig. 57). Vertex inside ocellar tri angle golden red, outside ocellar triangle golden green. Mesoscutum golden green with posterior 1/3 of notaular depressions golden red (Fig. 61). Scutellum golden red with sides bluish green metallic (Fig. 61). Propodeum golden green (Fig. 61). Fore coxa white, mid coxa dark brown with apical 1/3 white to completely dark brown, hind coxa golden green with apical half white (Fig. 63); femora, tibiae and tarsi on all legs white. Wings without pigmented areas; WIP very similar to that of the female (Fig. 65). Gaster with tergites 1-2 golden green with a large white spot medially, remaining tergites dark brown with purple metallic tinges.

Antenna as in Fig. 59, i.e. scape widest just below middle. Frons with engraved and strong reticulation (Fig. 67); antennal scrobes reaching frontal suture wide apart; transverse ridge straight medially. Vertex inside ocellar triangle with engraved and very weak reticulation, outside ocellar triangle smooth and shiny (Fig. 69); anterior part with a row of seven long and proclinate setae. Occipital margin rounded.

Pronotal collar without transverse carina (Fig. 71). Mesoscutum with raised and strong reticulation (Fig. 71), meshes of reticulation smaller on sidelobes than on midlobe, midlobe with pits (i.e. with very strong reticulation) posteromedially; notauli as smooth impressions in posterior 2/3. Scutellum very weak reticulation and shiny, smooth along posterior margin, with 3-4 pits medially on either side of imaginary median longitudinal line (Fig. 71). Dorsellum flat and smooth, anterolaterally with two foveae. Propodeum smooth and shiny (Fig. 71); propodeal callus with three setae. Fore wing speculum closed below. Petiole conical without shoulders.

Ratios. HE/MS/WM = 2.3/1.0/1.3; POL/OOL/POO = 14.4/6.4/1.0; WH/WT = 1.4; LW/LM/HW = 1.5/1.0/1.0; PM/ST = 1.0; MM/LG = 1.0.
