Type locality. “ Chili ” [ Chile].

Type depository. Muséum National d’Histoire Naturelle, Paris (lectotype examined).

Redescription. Length 5.0-7.0 mm; very elongate, convex, moderately shiny; nearly glabrous, elytra sparsely pubescent laterally and toward apex. Brownish-red; elytra, except sutural margin, and legs paler; antennal club yellowish. Head with epistome gibbous, rather irregularly, coarsely, densely, subrugosely punctured, alutaceous; clypeus feebly sinuate at middle, round at sides; rather thinly bordered, edge distinctly upturned, glabrous; genae elongately ciliate, obtusely round, protruding from the eyes; frontal suture cariniform, not tuberculate; front densely rather coarsely evenly punctured toward frontal suture only. Pronotum transverse, strongly convex, simply, rather densely and subregularly punctured, punctation denser on sides, and with a narrow postero-medial longitudinal areola impunctate; lateral margins arcuate, rather thickly bordered, edge elongately ciliate; hind angles obtusely round; base bordered. Scutellum wide, with curved sides and few sparse and superficial punctures. Elytra very elongate, strongly convex, epipleural carina elongately sparsely ciliate; striae deep, distinctly punctured, subcrenulate; interstriae moderately convex, finely alutaceous, distinctly and sparsely punctured, the lateral ones and toward apex sparsely but distinctly pubescent. Outer margin of fore tibiae with four teeth, the distal two very close, the third broadly separated, the fourth smaller than others ( Fig. 27 ). Hind tibiae superior spur slightly longer than first tarsal segment. Male: fore tibiae spur stout, obtusely truncate apically, inferior carina with a distinct tooth distally; pronotum regularly transverse, relatively more convex and more sparsely punctured on disc; metasternal plate with deep median longitudinal groove; first segment of hind tarsi as long as following three segments combined; aedeagus Fig. 28-29 . Female: fore tibiae spur slender and regularly acuminate, inferior carina without distal tooth; pronotum narrowed anteriorly, relatively less convex and more densely punctured on disc; metasternal plate superficially grooved at middle; first segment of hind tarsi shorter than following three segments combined.

Material examined. CHILE: “Chili”, ex Musaeo Harold (8 exx., lectotype and paralectotypes, MNHN) ; La Campana , Valparaiso, XII.1984, leg. L. E. Peña (3 exx., DCGI) .

Distribution. Chile (V Región de Valparaíso, Región Metropolitana, VII Región del Maule), Peru?. Harold (1866: 97) added “ Peru ” to the locality of the original description. No specimens from Peru are known, which places doubt on this record.

Bionomics. Almost unknown. Specimens were collected from November to February.
