Description: Female. 3.8 mm. Color: Orangish brown, with the following exceptions: clava whitish yellow gradually darkening to brown funicle; clypeus orange; posterior margin of scutum between notauli black; pro- and metacoxa off-white; distal half of metatibia brown; forewing with 3 brown, irregular, longitudinal bands emanating from distal end of submarginal vein, medial portion of marginal vein, and postmarginal vein, brownish yellow shaded areas present between bands; posterior margin of GT1, dorso-posterior margin of GT2–5, GT6 brown; GT7 off-white; ovipositor off-white proximally gradually darkening to brown distally. Head: Subrectangular in frontal view, about 1.1X wider than high; areolate, becoming transversely striate on lower face, striae angling toward clypeus; ratio of ocellocular: postocellar: mid-to-lateral ocellus distance: lateral ocellus diameter about 2.2: 4.2: 2.4: 1; scrobe high, reaching ventral margin of midocellus; scrobal basin transversely striate-areolate ventrally, becoming areolate dorsally, scrobal walls transversely areolate; interantennal carina strong, reaching about 0.4X height of scrobe; toruli separated by 1.6 torulus diameters; antennae clavate; scape height about 0.9X eye height; anellus about 1.2X longer than broad; ratio of scape: pedicel: anellus: F1: F2: F3 about 7.7: 2: 1: 2.4: 2: 1.8; F4 and F5 about as broad as long; clypeus well delimited. Mesosoma: Pronotum irregularly transversely striate-rugulose, scutum scabrous, scutellum antero-medially scabrous, laterally and posterior to frenum with strong longitudinal carinae; ratio of pronotum: scutum: scutel- lum: propodeum about 1.2: 1.9: 2.1: 1; mesosoma dorsally covered in thick, off-white setae; pronotum 2.1X wider than long; scutum 1.9X wider than long; marginal rim of scutellum with wide, upturned carina; metanotum narrow band with pits delimited by longitudinal striae; propodeum anteriorly with strong, dorso-ventrally flattened spine, with irregularly longitudinal carinae emanating from spine posteriorly and a single median carina emanating anteriorly; propodeum becoming areolate lateral to posterior longitudinal carinae; nucha wide, raised, roughly sculptured band; plicae absent; postspiracular sulcus deep, with irregular pits divided by transverse carinae; spiracle 1.6X own diameter from metanotum; callus areolate, with fine, white setae, projecting posteriorly into as spine lateral to spiracle; prepectus triangular, not in same plane as pronotum, abutting at about 135º angle; mesepimeron smooth with 2 longitudinal depressions with pits divided by transverse carinae; femoral depression deep, narrow, parallel-sided, with pits delimited by transverse carinae, well defined anteriorly and posteriorly; metapleuron areolate; pro- and mesocoxa with sparse white setae on anterior margins, metacoxa with sparse, white setae on disto-anterior margin; meso- and metatibia spinose; longer metatibial spur about 1.2X length of shorter spur, about 0.7X width of metatibia at point of spur insertion; metabasitarsus about 4.4X as long as wide, about 0.4X length of remaining tarsi; hind coxa distinctly transversely striate; macropterous; ratio of submarginal vein: marginal vein: postmarginal vein: stigmal vein 5.8: 3.2: 1.8: 1; entire wing (including speculum and basal cell) densely setose. Metasoma: About 1.4X length of mesosoma; petiole 2.1X longer than broad, coriaceous; ratio of GT1: GT2–6:GT7:ovipostor sheaths about 3.9:2.3:1.7:1; GT2–4 dorsally with single pair of long, fine, erect setae; GT3–4 dorso-laterally and GT5 dorsally with row of sparse, white setae; GT6 bare; GT47 and ovipositor sheath with dense white setae; ovipositor apico-dorsally obscured by sheath. Male: Unknown.

Etymology: villos-, meaning hairy, in reference to the thick, white setae covering the dorsal surface of the mesosoma in this species.

Distribution: Costa Rica.

Hosts: Unknown.
