Dentalion quadrifer sp. nov.
( Figs 1 View FIGURE 1 , 43–46 View FIGURES 43 – 46 , 69)
Diagnosis. Scutellum with 2 pairs of setae, one anterior and one posterior ( Fig. 44 View FIGURES 43 – 46 ); frontal suture reaching eyes at a level equal to half distance between posterior margin of anterior ocellus and anterior margin of posterior ocelli ( Fig. 46 View FIGURES 43 – 46 ); forewing costal cell ventrally with a sparse row of setae in apical ½ (as in Fig. 51 View FIGURES 47 – 53 ).
Similar to D. apon but frons and vertex with much stronger reticulation ( Figs 43, 46 View FIGURES 43 – 46 ), and mesoscutum and scutellum with distinctly smaller meshes ( Fig. 44 View FIGURES 43 – 46 ).
Description. FEMALE. Length 2.0 mm. Scape yellowish-brown with dorsal edge dark brown, pedicel and flagellum dark brown. Frons metallic bluish-green. Vertex golden-green. Mesoscutum, scutellum and propodeum metallic bluish-green. Coxae dark and metallic; femora and tibiae dark brown; tarsi with tarsomeres 1–3 white, 4 dark brown. Forewing hyaline. Gaster with tergite 1 metallic bluish-green, remaining tergites dark brown with metallic tinges.
Antenna as in Fig. 69. Frons with raised, strong reticulation ( Fig. 43 View FIGURES 43 – 46 ); frontal suture reaching eyes at a level equal to half distance between posterior margin of anterior ocellus and anterior margin of posterior ocelli. Vertex with raised, strong reticulation ( Fig. 46 View FIGURES 43 – 46 ). Occipital margin rounded. Eyes with sparse, scattered hairs ( Figs 43, 46 View FIGURES 43 – 46 ).
Pronotum without transverse carina close to posterior margin ( Fig. 44 View FIGURES 43 – 46 ). Mesoscutum with raised, strong reticulation ( Fig. 44 View FIGURES 43 – 46 ); notauli as narrow distinct grooves in anterior 1/3, not visible in posterior 2/3. Scutellum with raised, strong reticulation ( Fig. 44 View FIGURES 43 – 46 ); with 2 pairs of setae. Propodeum with very weak reticulation and with irregular longitudinal carinae medially ( Fig. 45 View FIGURES 43 – 46 ); callus with 2 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 “ COSTA RICA, Limón, 0.5 km E Braulio Carrillo National Park, San José-Limón road, 400 m, 9.ii.1991, J.S. Noyes”.
Etymology. Named for the four setae on scutellum, from the Latin quadrus = four, and the suffix – fer = carry.
Distribution. Costa Rica.
Remarks. The antennae are broken on the single available specimen. The left pedicel and flagellum on the left antenna, and the apical two flagellomeres are detached and glued separately on the card.
