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, dark, dark. Tibiae color (pro-, meso-, metatibia): pale, pale, anteriorly pale/posteriorly
dark. Tegula and humeral complex color: tegula pale, humeral complex dark.
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): 3.1–3.2 mm, rarely 3.3–3.4 mm. Fore wing length: 2.9–3.0 mm.
Ocular–ocellar line/posterior ocellus diameter: 1.7–1.9. Interocellar distance/posterior
ocellus diameter: 1.4–1.6. Antennal flagellomerus 2 length/width: 3.2 or more. Antennal
flagellomerus 14 length/width: 1.7–1.9. Length of flagellomerus 2/length of flagellomerus
14: 2.3–2.5. Tarsal claws: simple. Metafemur length/width: 3.2–3.3. 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: 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:
3.2–3.4. 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: 2.0–2.3. 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 or 1.0–1.1. Length of fore
wing veins r/2RS: 2.0–2.2. 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: 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.
Male. As in female.
Molecular data. Sequences in BOLD: 12, barcode compliant sequences: 12.
Biology/ecology. Solitary (Fig. 277). Hosts: Elachistidae, five species of Stenoma.
Distribution. Costa Rica, ACG.
Comments. This species is characterized by the combination of broadly rectangular
mediotergite 2 (its width at posterior margin 2.2 × its length), ovipositor sheaths
shorter than metatibia, and ovipositor relatively thin, with basal width less than 2.0 ×
its apical width after constriction.
