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): pale, pale, dark. Femora color (pro-, meso-, metafemur): pale, pale, mostly pale but posterior 0.2 or less dark. Tibiae color (pro-, meso-, metatibia): pale, pale, mostly pale but with posterior 0.2 or less dark. Tegula and humeral complex color: both pale. Pterostigma color: dark. Fore wing veins color: mostly dark (a few veins may be unpigmented). 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): 2.5-2.6 mm or 2.7-2.8 mm. Fore wing length: 2.5-2.6 mm or 2.7-2.8 mm. Ocular–ocellar line/posterior ocellus diameter: 2.0-2.2. Interocellar distance/posterior ocellus diameter: 1.7-1.9. Antennal flagellomerus 2 length/width: 2.6-2.8. Antennal flagellomerus 14 length/width: 1.0 or less. Length of flagellomerus 2/length of flagellomerus 14: 2.6-2.8. Tarsal claws: with single basal spine–like seta. 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: with punctures near margins, central part mostly smooth. Number of pits in scutoscutellar sulcus: 9 or 10. 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: more or less parallel–sided. 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: 3.6-3.9. Mediotergite 2 sculpture: with some sculpture, mostly near posterior margin. Outer margin of hypopygium: with a medially folded, transparent, semi–desclerotized area; with 0-3 pleats visible. Ovipositor thickness: anterior width at most 2.0 × posterior width (beyond ovipositor constriction). Ovipositor sheaths length/metatibial length: 0.6-0.7. Length of fore wing veins r/2RS: 1.4-1.6. Length of fore wing veins 2RS/2M: 1.1-1.3. Length of fore wing veins 2M/(RS+M)b: 0.7-0.8. Pterostigma length/width: 2.6-3.0. Point of insertion of vein r in pterostigma: clearly before half way point length of pterostigma. Angle of vein r with fore wing anterior margin: clearly outwards, inclined towards fore wing apex. Shape of junction of veins r and 2RS in fore wing: distinctly but not strongly angled.

Comments.

This species is characterized by hypopygium with a median folded, transparent, semi-desclerotized area with 1-3 pleats visible; ovipositor thin (thinner than width of median flagellomerus), and with basal width <2.0 × its apical width after constriction; tarsal claws with one basal spine-like seta; mediotergite 1 length 2.3 × its width; and mediotergite 2 with some sculpture near its posterior margin. The molecular data supports this species as divergent (Fig. 1).

Etymology.

We dedicate this species to Oscar Chávez in recognition of his diligent efforts as ACG chofer.
