ST. VINCENT, Lesser Antilles.

Holotype.

♀, BMNH (examined).

Description.

Female. Body color: body mostly dark except for some sternites which may be pale. Antenna color: scape, pedicel, and flagellum pale. Coxae color (pro-, meso-, metacoxa): pale, pale, partially pale/partially dark. Femora color (pro-, meso-, metafemur): pale, pale, anteriorly pale/posteriorly dark. Tibiae color (pro-, meso-, metatibia): pale, pale, anteriorly pale/posteriorly dark. Tegula and humeral complex color: both pale. Pterostigma color: mostly dark, with small pale area centrally. 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): 2.1-2.2 mm. Fore wing length: 2.1-2.2 mm. Ocular–ocellar line/posterior ocellus diameter: 1.7-1.9. Interocellar distance/posterior ocellus diameter: 2.0-2.2. Antennal flagellomerus 2 length/width: 2.6-2.8. Antennal flagellomerus 14 length/width: 1.1-1.3. 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 shallow, dense punctures (separated by less than 2.0 × its maximum diameter). Mesoscutellar disc: mostly smooth. Number of pits in scutoscutellar sulcus: 11 or 12. 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: 3.6-3.9. 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: 1.4-1.5. Length of fore wing veins r/2RS: 1.1-1.3. Length of fore wing veins 2RS/2M: 1.4-1.6. Length of fore wing veins 2M/(RS+M)b: 0.9-1.0. Pterostigma length/ width: 2.6-3.0. Point of insertion of vein r in pterostigma: clearly beyond 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.
