The morphological nomenclature, format for the description, and measurements employed follow that of
The specific epithet is based on the state of Rio Grande do Sul from where the type series was captured.
Male head moderately transverse; antenna with five rami on first to fifth flagellomeres (antennomeres three through seven), not articulated, remaining flagellomeres without rami. Mesoscutellum without grooves or lateral carina; propodeum without armature. Metasoma smooth and shining, without punctures.
Male: Total body length 1.32 mm, forewing length 0.85 mm. Coloration: Brownish throughout; Metasoma, mouthparts, and legs light brown; trochanters, femoral apices, tarsi, and tibial bases lighter. Wings hyaline with brown venation.
Head: Coriaceous, pubescent; moderately transverse. Ocelli forming an isosceles triangle with wider base, median ocellus bordered anteriorly by an obvious depression; preoccipital depression bounded by only a groove posterior to lateral ocelli and separated by a distance shorter than diameter; preoccipital suture visible until base of ocellar triangle. Compound eyes subcircular, pubescent, setae distinctly shorter than those on remainder of head. Supraclypeal depression conspicuous, with adjacent areas glabrous; intertorular carina present. Antenna flabellate, with coarse bristles (
Mesosoma: Mesoscutum, axillae, and mesoscutellum pubescent, coriaceous (
Wings: Forewing without cells, marginal vein long and pubescent, membrane with numerous microtrichia, pterostigma well developed (as in all species of the family), 0.12 mm diameter, poststigmal veins well defined and long (
Metasoma: Nine visible segments, integument smooth and shiny; fusiform, more convex ventrally than dorsally, ovoid in dorsal view.
Female: Unknown.
Unknown.
The number of lateral rami on the antenna, the dimensions of each flagellomere (length × width), and the form of the forewing veins serve to distinguish
