Description. Female. Body color: body mostly dark except for some sternites
which may be pale. Antenna color: scape and/or pedicel pale, flagellum dark or scape,
pedicel, and flagellum pale. Coxae color (pro-, meso-, metacoxa): pale, dark, dark.
Femora color (pro-, meso-, metafemur): anteriorly dark/posteriorly pale, dark, dark.
Tibiae color (pro-, meso-, metatibia): pale, pale, dark. Tegula and humeral complex
color: both pale. Pterostigma color: mostly pale and/or transparent, with thin
dark borders. Fore wing veins color: mostly white or entirely transparent. Antenna
length/body length: antenna very short, barely or not extending beyond mesosoma
length. Body in lateral view: distinctly flattened dorso–ventrally. Body length (head
to apex of metasoma): 2.0 mm or less or 2.1–2.2 mm. Fore wing length: 2.0 mm
or less or 2.1–2.2 mm. Ocular–ocellar line/posterior ocellus diameter: 2.6 or more.
Interocellar distance/posterior ocellus diameter: 1.7–1.9. Antennal flagellomerus 2
length/width: 1.4–1.6. Antennal flagellomerus 14 length/width: 1.0 or less. Length
of flagellomerus 2/length of flagellomerus 14: 1.7–1.9. Tarsal claws: simple. Metafemur
length/width: 2.6–2.7. Metatibia inner spur length/metabasitarsus length:
0.4–0.5. Anteromesoscutum: mostly smooth. Mesoscutellar disc: mostly smooth.
Number of pits in scutoscutellar sulcus: 11 or 12 or 13 or 14. Maximum height of
mesoscutellum lunules/maximum height of lateral face of mesoscutellum: 0.6–0.7.
Propodeum areola: partially defined by carinae on posterior 0.3–0.5 of its length,
widely open anteriorly. Propodeum background sculpture: mostly smooth except
around the areola or partly sculptured, especially on posterior 0.5. Mediotergite 1
length/width at posterior margin: 2.9–3.1. Mediotergite 1 shape: clearly narrowing
towards posterior margin. Mediotergite 1 sculpture: with some sculpture near lateral
margins and/or posterior 0.2–0.4 of mediotergite. Mediotergite 2 width at posterior
margin/length: 1.6–1.9. 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 (?) or 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: 0.8 or less. Length
of fore wing veins 2M/(RS+M)b: 1.1–1.3. 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: more or less perpendicular to fore
wing margin. Shape of junction of veins r and 2RS in fore wing: distinctly but not
strongly angled.
Molecular data. Sequences in BOLD: 2, barcode compliant sequences: 2.
Biology/ecology. Gregarious. Hosts: Crambidae, Diatraea considerata, D. magnifactella.
Distribution. Mexico. We have no reason to suspect that this species occurs in ACG.
Comments. Austin and Dangerfield (1989) revised this species and provided additional
photos and details.
