B1650E329463FFA3FF7E25EA4234F72A.taxon	discussion	Remarks. Ebonius differs from other Neotropical genera of Omalodini in the following combination of characters: body cylindrical almost parallel-sided; antennae with subtriangular club (oval in Scapomegas and Sphyracus); prosternum large, rounded at base (emarginated in Scapomegas and truncated in Sphyracus) and with carinal stria “ U ” - shaped (never “ U ” - shaped in other Omalodini); anterior margin of mesosternum widely emarginated (when compared to Omalodes); post-mesocoxal stria absent (present in Sphyracus and in some species of Scapomegas); sutural region of the elytra concave (flattened or weakly depressed in Scapomegas, Omalodes and Sphyracus); stria of the first abdominal sternum present anteriorly and laterally (absent on the anterior margin in other Omalodini); propygidium without tubercules (present in Cornillus of Omalodes) and pygidium with a transverse elevation in the middle, both structures with large and deep punctuation (mostly with smaller and shallow punctuation in Omalodes, Scapomegas and Sphyracus); male genitalia very similar to that illustrated by Leivas (2009: figs. 136 – 138, 143) for Omalodes (Diplogrammicus).	en	Degallier, Nicolas, Leivas, Fernando W.

B1650E329462FFA4FF7E26D24403F47D.taxon	discussion	Remarks. E. politus differs from E. lineiger (Marseul) (Figs. 3 C, D) by the shorter fourth dorsal stria of the elytra, the larger smooth surface of the pronotum disc and the more separated carinal stria. These differences might be considered as variations between populations, but the available material is insufficient to consider the possibility of synonymy between the two taxa. E. politus differs from E. aequatorius Lewis (Figs. 2 E, F) by not being as long and parallel-sided, the fourth and fifth dorsal striae being incomplete, and the mesosternum finely punctuated.	en	Degallier, Nicolas, Leivas, Fernando W.
