Dorsal setae mediumsized to long, of same size throughout. Head: Shining, smooth, prolonged anteriorly by distance of 1.5x the length of one eye; eyes located near base; ocelli located above basal line of eyes; interocular space wide; antennal segment II linear, not longer than head. Antennal segments (I:II:III:IV) 1: 2.2: 2.3: 2.5. Thorax: Pronotum dull, calli elevated and slightly shiny, with lateral margins straight and carinate on apical 3/4; anterior and posterior angles square; posterior margin concave. Pronotal lobes rugose. Hemelytra with characteristic punctures with a seta emerging from each. Lateral margins with long, dense and slightly curved pilosity.

Genitalia: Parietovaginal gland greatly reduced (Fig. 232); seventh sternite faintly punctured centrally (Fig. 233).

Male: Unknown.

Distribution: Brazil. (Fig. 200).

Material examined: Holotype BRAZIL: ♀ Amazonas, AM 010, km 26, Reserva Ducke, 1-XI-1977. USNM ; Paratype. ♀ Idem. (slide-mounted). MACN .

Etymology: The specific name refers to the site where this species has been collected.

Discussion: Despite the lack of males this is obviously a new species, distinguishable by its small size, wider body, carinate margins of pronotum, gratly reduced parietovaginal gland, and measurements.
