Type locality. Prov. Chubut ; [Patagonia] Argentina.

Type repository. Naturhistoriska Riksmuseet, Stockholm (lectotype examined).

Redescription. Length 5.0-6.0 mm; very elongate, convex, rather dull, glabrous. Yellowish-brown; elytra with sutural margin dark brown; legs yellowish-brown; antennal club yellowish. Head with epistome gibbous, almost evenly, sparsely, minutely punctured; punctures subgranulose; clypeus subtruncate anteriorly, widely round at sides, thinly bordered, edge strongly upturned, glabrous; genae widely round, elongately ciliate, moderately protruding from the eyes; frontal suture cariniform, not tuberculate; front finely, not closely punctured toward frontal suture only. Pronotum moderately transverse, strongly convex, simply, subregularly, not closely, moderately coarsely punctured, with a postero-medial longitudinal areola impunctate, somewhat depressed; lateral margins strongly arcuate, rather thickly bordered, edge elongately densely ciliate; hind angles broadly round; base faintly bisinuate, rather thickly bordered. Scutellum superficially alutaceous, finely punctured almost throughout. Elytra elongate, subparallelsided; epipleural carina densely elongately ciliate; striae rather fine, superficially punctured, feebly crenulate; interstriae slightly convex, finely alutaceous, glabrous, superficially sparsely irregularly punctured. Hind tibiae superior spur somewhat longer than first tarsal segment, latter as long as following two segments combined. Male: pronotum not narrowed anteriorly; fore tibiae spur stout and downward bent ( Fig. 17 ); apical margin of hind tibiae denticulate before inferior spur ( Fig. 18 ); aedeagus Fig. 21-22 . Female: pronotum subquadrate, weakly narrowed anteriorly; fore tibiae spur slender and nearly straight.

Remarks. The shape of epipharynx ( Fig. 16 ) differs somewhat from that of the other Orodaliscoides species but the complex of morpho-anatomical characters indicate that, with some doubt, it belongs to this genus.
