Key to the males of Falsocis Pic

1 Frontoclypeal ridge with corners obtusely angulate ( Fig. 3–4 ). Anterior pronotal plate completely concealing the head from above ( Fig. 1 ), with anterior margin bearing a row of stout setae similar to those of lateral margins. Pronotal disc ( Fig. 1 ) with dense punctation, punctures separate by a distance of one puncture width or less. Elytral apices explanate and broadly crenulate ( Figs 1–3 ). Epipleura larger at base and tapering to basal third, then expanding again until the apex ( Fig. 3 ). Aedeagus elongate, around four times as long as wide ( Fig. 6 ). TL around 3mm. Amazon Forest ( Fig. 24 ), in French Guiana and northern Brazil............................................................................................................................. Falsocis opacus Pic

- Frontoclypeal ridge with corners produced upwards to form a pair of long curved horns ( Figs 8 , 10 ). Head partially visible from above ( Fig. 7 ). Apex of anterior pronotal plate bearing a patch of long setae on either side ( Figs 7 , 9–11 ). Pronotal disc with sparse punctation ( Fig. 7 ), punctures separate by a distance of one to three puncture widths. Elytral apices broadly rounded. Epipleura larger at base and tapering to basal third, then continuing as a narrow line ( Figs 9 , 11 , 16 ). Aedeagus subquadrate, around twice as long as wide ( Figs 20, 22 ). TL 2.00– 2.80mm. Atlantic Forest ( Fig. 24 ): southeastern to the extreme south of northeastern Brazil......................................................................................... Falsocis brasiliensis sp. nov.
