Eudorylas subvexus Rafael View in CoL , n. sp.

( Fig. 18–25 View FIGURES 14 – 32. 14 – 17 )

Diagnosis. Antennae with scape and pedicel brown, flagellum yellow, acute. Legs predominantly yellow. Fore and midfemora with ventral ctenidia. Fore and midtibia with distinct posteroventral bristle. Abdomen predominantly shining black. Phallic guide with long and wide upward dorsal process.

Description (ɗ). Body length 3.0 mm; wings 3.4 mm. Antennae with scape and pedicel brown, flagellum yellow. Frons and face gray pruinose. Thorax dark brown to black, brown pruinose dorsally and gray pruinose laterally (mesopleuron and postnotum). Postpronotal lobe yellow. Legs yellow with coxae brown to black and fifth tarsomeres brown. Forefemur and midfemur with short ventral ctenidia. Foretibia and midtibia with posteroventral bristle. Wings hyaline, except for brown pterostigma; crossvein r­m located near basal one third of the cell dm; last section of vein M1 almost straight. Halteres yellow. Abdomen ( Fig. 14 View FIGURES 14 – 32. 14 – 17 ) shining black, brown pruinose, except tergite 1 and base of tergite 2 gray pruinose. Terminalia with large membranous area apically on syntergosternite 8; surstyli ( Fig. 19 View FIGURES 14 – 32. 14 – 17 ) asymmetrical, in lateral view as in Figs.. 20, 21. Hypandrium and phallus as in Fig. 22 View FIGURES 14 – 32. 14 – 17 . Hypandrium with long and wide upward dorsal process on phallic guide. Ejaculatory apodeme as in Figs. 23, 24 View FIGURES 14 – 32. 14 – 17 .

Female. Body length 2.8–3.0 mm; wing 3.3–3.5 mm. Frons shining black near ocellar tubercle. Tergite 2 more extensively gray pruinose in anterior view. Syntergosternite 7+8 and ovipositor ( Fig. 25 View FIGURES 14 – 32. 14 – 17 ) yellow to brown; ovipositor almost straight, slightly shorter than the bilobate syntergosternite. In others respects identical to description of male.

Material. Holotype ɗ (INPA). Verbatim text of three pin labels: NICARAGUA, Granada, Volcán Mombacho, San Joaquin #2 [white paper] / 28.ii.1999, J.M. Maes, Malaise trap [white paper] / Holotype ɗ, Eudorylas subvexus Rafael [red paper].

Etymology. The specific name refers to the upward dorsal process of the hypandrium (from Latin subvexus = sloping upward).

Remarks. Eudorylas subvexus , n. sp. is close to E. spinosus (Hardy) in the abdominal coloration and pruinosity pattern, in the shape of the surstyli and of the ovipositor. It differs by the long and wide upward dorsal process on the phallic guide.
