Updated identification key to Falsocis species

1. Epipleura enlarged posteriorly, forming a slightly or strongly explanate posterolateral edge in elytra, conspicuously or barely visible from above....................................................2

1’. Epipleura narrowing to apex, forming a narrow, not explanate, posterolateral edge in elytra, not visible from above........... 3

2. Pronotum with lateral edges explanated, completely visible from above. Posterior elytral edge (outer edge of epipleura) simple (not crenulate), barely visible from above. Known from Panamá, Costa Rica, and Colombia............................. .......... Falsocis aquilonius Lopes-Andrade & Lawrence, 2011

2’. Pronotum with lateral edges narrow, not visible from above except for anterior and posterior corners. Posterior elytral edge (outer edge of epipleura) crenulate, easily visible from below and above. Known from northern Brazil (Altamira, state of Pará) and French Guyana........................................ ....................................................... Falsocis opacus Pic, 1916

3. Pronotal punctation deep and coarse, with punctures usually separated by half a puncture-width or less at disc. Anterior plate of pronotum in males with apex acute or broadly rounded, bearing a patch or row of stout bristles shorter than half an eye-width .......................................................4

3’. Pronotal punctation shallow and fine, with punctures usually separated by about a puncture-width at disc. Anterior plate of pronotum in males with apex straight, barely emarginated or slightly rounded, bearing slender setae usually as long as to twice as long (or more) than an eye-width ....................5

4. Elytral vestiture conspicuously dense, punctures bearing stout bristles (0.07-0.08 mm), separated from each other by one to two punctures, the latter punctures bearing minute setae (~ 0.03 mm). Anterior pronotal plate in males ending in acute apex, even in small males. Known from the coastal Atlantic Forest from southeastern to south Brazil ............................. ............. Falsocis occultus Lopes-Andrade & Lawrence, 2011

4’. Elytral vestiture sparse, punctures bearing stout bristles (0.04- 0.05 mm) separated from each other by about five punctures, the latter punctures bearing minute inconspicuous setae (~ 0.01 mm; there is a third type of vestiture of slender setae ~ 0.03 mm), but very sparse. Anterior pronotal plate in males ending in a rounded apex (a bit angulate in large males, but never acute). Known only from the type locality (Sooretama, Espírito Santo, Brazil)................. Falsocis sooretama sp. nov.

5. Anterior pronotal angles distinctly produced forward and somewhat acute. Males with head devoid of conspicuous projection behind each eye; long setae of anterior pronotal plate organized into two tufts. Known from French Guyana and the Atlantic Forest in Brazil........................................... ............................. Falsocis brasiliensis Lopes-Andrade, 2007

5’. Anterior pronotal angles barely produced forward and rounded. Males with head bearing a conspicuous triangular plate, projected outward, behind each eye; long setae of anterior pronotal plate organized as a row, not forming tufts. Known only from the type locality, Santarém (Pará, Brazil) ............ .............. Falsocis egregius Lopes-Andrade & Lawrence, 2011
