Key to Subgenera of Eucatops (from Salgado, 2011d)

1a Elytra covered in developed granules and dense punctuation, normally dispersed, preventing transverse striation from being differentiated; pubsecence always long................................................. subgenus Sphaerocatops

1b Elytra lacking developed granules, punctuation more or less dense, forming transverse striae; pubsecence short, hardly ever long................................................................................................ 2

2a Body normally less than 6 mm in length; transverse striae completely covering elyta and always visible; spermathecal complex more or less robust, spermathecal duct filiform or tubular, the latter with or without a basal piece, which, when present, normally lacks lateral prolongation............................................................ subgenus Eucatops

2b Body over 6 mm long; transverse striae very fine, almost absent, not covering entire elytra in this case; spermathecal complex always robust, tubular with prolongation in developed basal piece...............................subgenus Napocatops
