Eulophinusia andreamezae Hansson , sp. nov.

Figures 1–7 View FIGURES 1–5 View FIGURES 6–9 , 10 View FIGURE 10

Diagnosis. Differs from E. cydippe (the type species of Eulophinusia ) in the setation and sculpture on midlobe of mesoscutum: with numerous scattered setae and with the socket of each seta surrounded by a large ring ( Fig. 6 View FIGURES 6–9 ); E. cydippe has its setae in two rows and sockets lack rings ( Fig. 8 View FIGURES 6–9 ).

Description (female holotype). Length of body 1.4 mm (paratypes 1.1–1.4 mm). Antenna ( Fig. 3 View FIGURES 1–5 ) with scape white with a dark brown spot medially, pedicel and flagellum dark brown; flagellum stout with transverse flagellomeres, funicle 4-segmented and clava 2-segmented. Frons below frontal suture yellowish-white with two transverse dark brown bands, one level with antennal toruli and one just below frontal suture ( Fig. 5 View FIGURES 1–5 ); with strong reticulation, smooth just below frontal suture. Vertex metallic bluish-green inside ocellar triangle, brown outside ocellar triangle, with strong reticulation. Occipital margin rounded.

Mesoscutum metallic bluish-green ( Fig. 2 View FIGURES 1–5 ); with numerous scattered setae and with the socket of each seta surrounded by a raised ring ( Fig. 6 View FIGURES 6–9 ); notauli indicated by a groove in anterior ⅓ ( Fig. 6 View FIGURES 6–9 ); with strong reticulation. Mesoscutellum metallic bluish-green with lateral and posterior margins yellowish-white ( Fig. 2 View FIGURES 1–5 ); flattened ( Figs 6, 7 View FIGURES 6–9 ), 0.7× as long as wide, with sculpture similar to a jigsaw puzzle ( Fig. 7 View FIGURES 6–9 ); without sublateral grooves or pit-rows; with two pairs of setae attached laterally. Axillae ( Fig. 2 View FIGURES 1–5 ) metallic bluish-green with a yellowish-white band medially; strongly advanced forwards and with strong reticulation ( Fig. 6 View FIGURES 6–9 ). Dorsellum ( Fig. 2 View FIGURES 1–5 ) metallic bluish-green with posterior margin yellowish-white; triangular with weak reticulation and slightly convex, 1.0× as long as length of median propodeum. Propodeum ( Fig. 2 View FIGURES 1–5 ) metallic bluish-green, with parts between spiracles with very weak reticulation and propodeal callus with strong reticulation ( Fig. 6 View FIGURES 6–9 ), with a carina that follows posterior margin of dorsellum and with a complete median carina; propodeal callus with five setae. Legs ( Fig. 1 View FIGURES 1–5 ) with coxae dark brown with metallic tinges; fore and mid femora white with ventral margin dark brown, hind femur dark brown with base white; fore and mid tibia white, hind tibia dark brown with apical ¼ white; tarsi white. Wings ( Fig. 1 View FIGURES 1–5 ) hyaline, veins yellowish-brown and setae dark brown; fore wing with submarginal vein with seven setae on dorsal surface; speculum very small and closed posteriorly, separated from cubital line by several rows of setae; costal cell with a complete row of setae on ventral surface, and margin with eight setae in apical ⅓; basal cell bare; hind wing with apex rounded.

Petiole black and shiny, very short and transverse. Gaster ( Fig. 2 View FIGURES 1–5 ) ovate, metallic purple, and smooth.

Variation. Apart from some variation in size there is little variation in the material.

Hosts and biology. Hyperparasitoid on gregarious Hypomicrogaster largus Valerio ( Braconidae : Microgastrinae ) parasitizing caterpillar of Anadasmus Janzen 11 ( Lepidoptera : Depressariidae ) feeding on Ocotea insularis (Lauraceae) . The eulophid parasitoids emerged from the microgastrine cocoons attached to the leaf close to the lepidopteran host ( Fig. 10 View FIGURE 10 ). Twenty-three females and two males of E. andreamezae emerged from one reared wildcaught caterpillar from ACG (Área de Conservación Guanacaste) rain forest.

Distribution. Canada, Costa Rica (Alajuela, Heredia & Puntarenas Provinces), Dominican Republic. DNA barcoding may possibly reveal a complex of sibling species, as being found to be the case with many other ACG parasitic small wasps (e.g. Smith et al. 2008).

Etymology. Named in honor of Ministra Andrea Meza Murillo of the Ministerio de Recursos Naturales y Energía de Costa Rica in recognition of her taking on this difficult ministerial task mid-government, and for being sympathetic to the peculiar needs of Área de Conservación Guanacaste for its survival.
