Description. Female. Body color: body mostly dark except for some sternites
which may be pale. Antenna color: scape and/or pedicel pale, flagellum dark. Coxae
color (pro-, meso-, metacoxa): pale, pale, pale. Femora color (pro-, meso-, metafemur):
pale, pale, pale. Tibiae color (pro-, meso-, metatibia): pale, pale, pale. 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): 2.0 mm or less. Fore wing length: 2.3–
2.4 mm. Ocular–ocellar line/posterior ocellus diameter: 2.0–2.2. Interocellar distance/
posterior ocellus diameter: 1.4–1.6. Antennal flagellomerus 2 length/width: 2.9–3.1.
Antennal flagellomerus 14 length/width: 1.4–1.6. Length of flagellomerus 2/length of
flagellomerus 14: 2.3–2.5. Tarsal claws: with single basal spine–like seta. Metafemur
length/width: 3.2–3.3. Anteromesoscutum: mostly with shallow, dense punctures
(separated by less than 2.0 × its maximum diameter). Mesoscutellar disc: with a few
sparse punctures. 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: 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: 3.8–4.0. Mediotergite 1 shape:
clearly narrowing 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: 3.6–3.9. 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.
Ovipositor sheaths length/metatibial length: 0.8–0.9. 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: 0.9–1.0. 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: clearly outwards, inclined towards fore wing apex. Shape of junction of
veins r and 2RS in fore wing: strongly angulated, sometimes with a knob. Male. The only male specimen has dark brown metacoxa and metatarsus.
Molecular data. Sequences in BOLD: 2, barcode compliant sequences: 2.
Biology/ecology. Malaise trapped.
Distribution. Costa Rica, ACG
Comments. This species is characterized by the combination of small size (body
length 2.0 mm, fore wing length 2.4 mm), and all legs (including coxae) fully yellow
or whitish-yellow.
