Holotype. ♀ in CNC. Specimen labels: 1. DHJPAR0012499. 2. COSTA RICA,
Guanacaste, ACG, Sector El Hacha, Sendero Bejuquilla, 280 meters, 11.03004 Longitude:

Description. Female. Body color: head pale, mesosoma extensively pale (anteromesoscutum
and scutellar disc). Antenna color: scape and/or pedicel pale, flagellum
dark. Coxae color (pro-, meso-, metacoxa): pale, pale, partially pale/partially 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). Body in lateral
view: not distinctly flattened dorso–ventrally. Body length (head to apex of metasoma):
3.1–3.2 mm. Fore wing length: 3.3–3.4 mm. Ocular–ocellar line/posterior ocellus diameter:
2.3–2.5. Interocellar distance/posterior ocellus diameter: 2.3–2.5. Antennal
flagellomerus 2 length/width: 2.6–2.8. Antennal flagellomerus 14 length/width: 1.7–
1.9. Length of flagellomerus 2/length of flagellomerus 14: 2.3–2.5. Tarsal claws: with
single basal spine–like seta. Metafemur length/width: 2.8–2.9. Anteromesoscutum:
mostly with deep, dense punctures (separated by less than 2.0 × its maximum diameter). Mesoscutellar disc: mostly punctured. Number of pits in scutoscutellar sulcus:
5 or 6. Maximum height of mesoscutellum lunules/maximum height of lateral face of
mesoscutellum: 0.4–0.5. Propodeum areola: partially defined by carinae on posterior
0.3–0.5 of its length, widely open anteriorly. Propodeum background sculpture: mostly
sculptured. Mediotergite 1 length/width at posterior margin: 2.6–2.8. Mediotergite
1 shape: mostly parallel–sided for 0.5–0.7 of its length, then narrowing posteriorly so
mediotergite anterior width >1.1 × posterior width. 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: 3.2–3.5. Mediotergite 2 sculpture: with some sculpture, mostly near
posterior margin. Outer margin of hypopygium: with a wide, medially folded, transparent,
semi–desclerotized area; usually with 4 or more pleats. Ovipositor thickness:
anterior width at most 2.0 × posterior width (beyond ovipositor constriction). Ovipositor
sheaths length/metatibial length: 0.8–0.9. Length of fore wing veins r/2RS: 2.3
or more. Length of fore wing veins 2RS/2M: 0.9–1.0. 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: about 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.
Male. Unknown.

Distribution. Costa Rica, ACG.
Comments. This species is very distinctive, characterized by head and most of
mediotergite 1 orange, mediotergite 3 partially yellow, and mesoscutellar disc mostly
