Type material: Holotype male: Brazil: Rio de Janeiro, Planalto Itatiaia (44°33'W, 22°29'S), 2300 m elevation, 20.04.1958, leg. R. Arlé ( UIC). GoogleMaps

Etymology: The specific name derived from the country, where the species was collected.

Description: Length: 1.7 mm, Colouration: Red, legs and antennae yellow.

Head: 0.26 mm long, 0.37 mm wide; clypeus semicircular; setiferous punctation moderately deep and dense; setae yellow; netlike microsculpture deep and dense; surface matt.

Antennae slightly longer than head and half of pronotum combined; first antennomere rectangular thick; second oblong, slightly less wide than first; third antennomere conical, slightly shorter and narrower than second; fourth antennomere as wide as third; approximately quadrate; following antennomeres slightly increasing in width; penultimate antennomere 1.5 times as wide as long.

Pronotum: 0.36 mm long, 0.40 mm wide; widest behind middle; slightly and evenly narrowed to anterior angles; to posterior angles narrowed in smooth convex curve; continuing to posterior margin without forming distinct angles; lateral margin extremely fine; not visible in dorsal aspect; setiferous punctation deep, coarse; on average, interstices between punctures half as wide as diameter of punctures; setae light yellow; moderately wide midline impunctate; netlike microsculpture deep and dense; surface matt.

Elytra: 0.26 mm long, 0.39 mm wide; widest in posterior third; with distinct shoulders; setiferous punctation still coarser than on pronotum; nearly coriaceous; setae light yellow; netlike microsculpture deep and dense; surface matt.

Abdomen with setiferous punctation still coarser than on elytra; on average, interstices between punctures one third as wide as diameter of punctures; without microsculpture; surface matt.

Protibia with few spines on outer edge and few long setae on posterior face.

Aedeagus with smoothly curved apical lobe; paramera slightly shorter than apical lobe and with long straight seta at apex; endophallus thick with elongate coil at lower and upper end and two narrow coils in between.

Diagnosis: Among the genus the species can be easily identified by the distinct microsculpture and the evenly curved sides of the pronotum.
