Description.

Female. Body color: body mostly dark except for some sternites which may be pale. Antenna color: scape, pedicel, and flagellum dark. Coxae color (pro-, meso-, metacoxa): dark, dark, dark. Femora color (pro-, meso-, metafemur): pale, anteriorly dark/posteriorly pale, dark. Tibiae color (pro-, meso-, metatibia): pale, pale, anteriorly pale/posteriorly dark. Tegula and humeral complex color: tegula dark, humeral complex half pale/half dark. Pterostigma color: dark. Fore wing veins color: partially pigmented (a few veins may be dark but most are pale). Antenna length/body length: antenna about as long as body (head to apex of metasoma); if slightly shorter, at least extending beyond anterior 0.7 metasoma length. Body in lateral view: not distinctly flattened dorso–ventrally. Body length (head to apex of metasoma): 3.1-3.2 mm. Fore wing length: 3.1-3.2 mm. Ocular–ocellar line/posterior ocellus diameter: 2.3-2.5. Interocellar distance/posterior ocellus diameter: 1.7-1.9. Antennal flagellomerus 2 length/width: 2.9-3.1. Antennal flagellomerus 14 length/width: 1.4-1.6. Length of flagellomerus 2/length of flagellomerus 14: 2.3-2.5. Tarsal claws: simple. Metafemur length/width: 3.0-3.1. Metatibia inner spur length/metabasitarsus length: 0.4-0.5. Anteromesoscutum: mostly with deep, dense punctures (separated by less than 2.0 × its maximum diameter). Mesoscutellar disc: mostly smooth. Number of pits in scutoscutellar sulcus: 7 or 8. Maximum height of mesoscutellum lunules/maximum height of lateral face of mesoscutellum: 0.4-0.5. Propodeum areola: completely defined by carinae, including transverse carina extending to spiracle. Propodeum background sculpture: mostly sculptured. Mediotergite 1 length/width at posterior margin: 2.3-2.5. Mediotergite 1 shape: slightly widening from anterior margin to 0.7-0.8 mediotergite length (where maximum width is reached), then narrowing towards posterior margin. Mediotergite 1 sculpture: mostly sculptured, excavated area centrally with transverse striation inside and/or a polished knob centrally on posterior margin of mediotergite. Mediotergite 2 width at posterior margin/length: 2.8-3.1. Mediotergite 2 sculpture: mostly smooth. Outer margin of hypopygium: with a wide, medially folded, transparent, semi–desclerotized area; usually with 4 or more pleats. Ovipositor thickness: about same width throughout its length. Ovipositor sheaths length/metatibial length: 1.4-1.5. Length of fore wing veins r/2RS: 1.7-1.9. Length of fore wing veins 2RS/2M: 1.7-1.8. Length of fore wing veins 2M/(RS+M)b: 0.5-0.6. Pterostigma length/width: 3.1-3.5. Point of insertion of vein r in pterostigma: about half way point length of pterostigma. Angle of vein r with fore wing anterior margin: more or less perpendicular to fore wing margin. Shape of junction of veins r and 2RS in fore wing: distinctly but not strongly angled.

Biology/ecology.

Solitary (Fig. 290). Host: Elachistidae , species with interim names elachJanzen01 Janzen244, elachJanzen01 Janzen250.

Distribution.

Costa Rica, ACG.

Comments.

This species is characterized by tegula and humeral complex of different color, pterostigma brown, ovipositor sheaths 1.4-1.5 × as long as metatibia length, and body length and fore wing length at least 3.2 mm. The relatively long ovipositor sheaths and molecular data support this species as unique among the Mesoamerican fauna so far known.

Etymology.

We dedicate this species to Isidro Villegas in recognition of his diligent efforts for the ACG Programa de Sectores.
