Description. Female. Body color: body mostly dark except for some sternites
which may be pale. Antenna color: scape and/or pedicel dark, flagellum pale. Coxae
color (pro-, meso-, metacoxa): pale, pale, dark. Femora color (pro-, meso-, metafemur):
pale, pale, pale. Tibiae color (pro-, meso-, metatibia): pale, pale, pale, rarely pale, pale, mostly pale but with posterior 0.2 or less dark. Tegula and humeral complex color:
both pale. Pterostigma color: dark with pale spot at base. Fore wing veins color: partially
pigmented (a few veins may be dark but most are pale). Antenna length/body
length: antenna shorter than body (head to apex of metasoma), not extending beyond
anterior 0.7 metasoma length. Body in lateral view: not distinctly flattened dorso–ventrally.
Body length (head to apex of metasoma): 2.7–2.8 mm, 2.9–3.0 mm or 3.1–3.2
mm. Fore wing length: 2.5–2.6 mm, 2.7–2.8 mm or 2.9–3.0 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: 2.0–2.2. Antennal flagellomerus 14
length/width: 1.0 or less or 1.1–1.3. Length of flagellomerus 2/length of flagellomerus
14: 2.0–2.2. Tarsal claws: with single basal spine–like seta. Metafemur length/width:
2.8–2.9. Metatibia inner spur length/metabasitarsus length: 0.6–0.7. 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: 0.2–0.3. Propodeum areola:
completely defined by carinae, including transverse carina extending to spiracle. Propodeum
background sculpture: partly sculptured, especially on anterior 0.5. Mediotergite
1 length/width at posterior margin: 1.4–1.6. Mediotergite 1 shape: clearly widening
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: 3.2–3.5. Mediotergite
2 sculpture: more or less fully sculptured, with longitudinal striation. 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: 1.0–1.1. Length of fore wing
veins r/2RS: 1.7–1.9. Length of fore wing veins 2RS/2M: 0.9–1.0. Length of fore wing
veins 2M/(RS+M)b: 0.9–1.0. Pterostigma length/width: 2.1–2.5. 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. Similar to female, except for shape of mediotergite 1 which is more rectangular,
and coloration of meso and metafemur which tends to be darker in some specimens.
Molecular data. Sequences in BOLD: 16, barcode compliant sequences: 15,
haplotypes: 2.
Biology/ecology. Gregarious. Mostly recorded from Lepidoptera species on
stored products –its cosmopolitan distribution is likely due to human transfer from an
unknown source. Hosts: Gelechiidae, Lasiocampidae, Lecithoceridae, Lymantriidae,
Pyralidae, Thaumetopoeidae, Tineidae, Tortricidae, Zygaenidae. The correctness of
some of these host records is questionable because it is unlikely that a single species has
such a wide host range.
Distribution. Cosmopolitan, this species has been recorded from 50 countries in
all continents but there is no suggestion that it occurs in ACG. Comments. The geographical coverage of the barcoded specimens includes Canada
and New Zealand, but all sequences are almost identical. The only exceptions are
some extralimital specimens (British Columbia, Canada) which seem to represent a
different species based on body color and the barcode of one specimen. Because those
specimens are not from Mesoamerica, they will be dealt with elsewhere.
