Type locality.

PUERTO RICO, Mayaguez.

Holotype.

♀, NMNH (examined).

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): pale, pale, partially pale/partially dark. Femora color (pro-, meso-, metafemur): pale, pale, pale. Tibiae color (pro-, meso-, metatibia): pale, pale, mostly pale but with posterior 0.2 or less dark. Tegula and humeral complex color: both pale. Pterostigma color: entirely pale or transparent, translucent. Fore wing veins color: partially pigmented (a few veins may be dark but most are pale). 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): 2.3-2.4 mm. Fore wing length: 2.5-2.6 mm. Ocular–ocellar line/posterior ocellus diameter: 2.0-2.2. Interocellar distance/posterior ocellus diameter: 2.0-2.2. Antennal flagellomerus 2 length/width: 2.9-3.1. Antennal flagellomerus 14 length/width: 1.1-1.3. Length of flagellomerus 2/length of flagellomerus 14: 2.6-2.8. Tarsal claws: with single basal spine–like seta. Metafemur length/width: 3.2-3.3. Metatibia inner spur length/metabasitarsus length: 0.4-0.5. Anteromesoscutum: mostly with shallow, sparse punctures (separated by more 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: completely defined by carinae, including transverse carina extending to spiracle. Propodeum background sculpture: mostly sculptured. Mediotergite 1 length/width at posterior margin: 2.9-3.1. 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: 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: about same width throughout its length. Ovipositor sheaths length/metatibial length: 0.8-0.9. Length of fore wing veins r/2RS: 2.0-2.2 or 2.3 or more. 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: 3.6 or more. 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.

No molecular data available for this species.

Biology/ecology.

Solitary, white cocoons (Muesebeck 1921 and 1958). Hosts: Crambidae, Diaphania hyalinata .

Distribution.

Cuba, Puerto Rico; there is no suggestion that this wasp occurs in ACG, though there are numerous species of Diaphania that breed in ACG.
