Achrysocharoides robinicolus sp. nov.
( Figs 37–48 View FIGURES 37 – 42 View FIGURES 43 – 48 , 57, 60 View FIGURES 55 – 60 , 67–68 View FIGURES 61 – 68 )
Diagnosis. Achrysocharoides robinicolus is very similar to A. robiniae but differs in having a narrower male scape ( Figs 44 View FIGURES 43 – 48 , 68 View FIGURES 61 – 68 ), which is 3.0X as long as wide (holotype) (1.8X as long as wide in holotype of A. robiniae , Figs 32 View FIGURES 31 – 36 , 66 View FIGURES 61 – 68 ), anteromedian white spot in male gaster triangular and small, reaching to posterior margin of 1st or 2nd tergites ( Figs 57, 60 View FIGURES 55 – 60 ) (shaped as a pentagon in A. robiniae , Figs 56, 59 View FIGURES 55 – 60 ), hind coxae in both sexes with base brown to metallic ( Figs 47–48 View FIGURES 43 – 48 ) (completely white in both sexes of A. robiniae , Figs 35–36 View FIGURES 31 – 36 ).
Description. FEMALE. Length 1.2–1.4 mm.
Scape white with apical 1/3 infuscate; pedicel and flagellum brown with weak metallic tinges. Frons below frontal suture golden-green to golden-red, antennal scrobes golden-red, above frontal suture metallic bluish-purple with metallic green tinges. Vertex inside ocellar triangle golden-red, outside ocellar triangle golden-green. Mesoscutum and scutellum metallic bluish-green. Propodeum metallic blue with green tinges. Legs white, hind coxa with base brown to metallic. Wings hyaline. Gaster with first two tergites golden-green, remaining tergites dark brown with metallic green tinges.
Antenna as in Fig. 67 View FIGURES 61 – 68 . Frons below level of toruli smooth and shiny, between level of toruli and frontal suture with raised and strong reticulation with antennal scrobes smooth, above frontal suture smooth and shiny. Vertex inside ocellar triangle with engraved and very weak reticulation, outside ocellar triangle smooth and shiny. Occipital margin with a sharp edge behind ocellar triangle.
Pronotal collar with a sharp carina. Mesoscutum with midlobe with raised and strong reticulation, sidelobes with fine and weak reticulation; notauli as smooth impressions in posterior 2/3. Scutellum with rows of punctate-reticulate pits on each side, remaining surfaces with very weak and engraved reticulation to smooth. Dorsellum flat and smooth, anterolaterally with two foveae. Propodeum smooth and shiny with two submedian carinae that diverge towards posterior margin of propodeum; propodeal callus with three setae. Forewing speculum closed below. Petiole conical without shoulders.
Ratios. HE/MS/WM = 3.9/1.0/1.7; POL/OOL/POO = 1.4/1.0/1.0; WH/WT = 1.2; LW/LM/HW = 1.7/1.0/ 1.1; PM/ST = 1.0; MM/LG = 1.1–1.2.
MALE. Length 1.3–1.4 mm.
Scape white; pedicel brown with metallic tinges and with ventral side white; flagellum dark brown with golden-green tinges. Frons below level of toruli golden-green or golden-red, above level of toruli metallic blue. Vertex inside ocellar triangle golden-red, outside ocellar triangle metallic bluish-green. Mesoscutum and scutellum metallic blue with green tinges. Propodeum metallic blue with green tinges. Legs white, hind coxae with base brown to metallic. Wings hyaline. Gaster with tergites 1, 2, 6, 7 golden-green, 3–5 dark brown with metallic tinges, anteromedially with a triangular white spot that extends over first tergite, sometimes reaching posterior margin of 2nd tergite.
Antenna as in Fig. 68 View FIGURES 61 – 68 . Frons below level of toruli smooth and shiny, between level of toruli and frontal suture with strong and transverse striae, above frontal suture medially with raised and rather weak reticulation and close to eyes smooth. Vertex inside ocellar triangle with engraved and very weak reticulation, outside ocellar triangle smooth and shiny. Occipital margin with a sharp edge behind ocellar triangle.
Pronotal collar with a sharp carina. Mesoscutum with midlobe with raised and strong reticulation, sidelobes with fine and weak reticulation; notauli as smooth impressions in posterior 2/3. Scutellum with rows of punctate-reticulate pits on each side, remaining surfaces with very weak and engraved reticulation to smooth. Dorsellum flat and smooth, anterolaterally with two foveae. Propodeum smooth and shiny with two submedian carinae that diverge towards posterior margin of propodeum; propodeal callus with three setae. Forewing speculum closed below. Petiole conical without shoulders.
Ratios. HE/MS/WM = 2.5/1.0/1.2; POL/OOL/POO = 3.2/1.8/1.0; WH/WT = 1.3; LW/LM/HW = 1.7/1.0/ 1.1; PM/ST = 1.1; MM/LG = 1.1–1.2.
