Key to males of Dragomiris (modified from Martins & Monné 1980; Di Iorio 1996):

1. Prothorax with parallel lateral margins; punctation on pronotum, lateral and ventral sides ( Fig. 2c ) of prothorax fine, with reticulated aspect; marginal anterior band on prosternum apparently narrow, not clearly delimited, provided with a dense pubescence ( Fig. 3c ); basal half of elytra with minute punctation, and finely corrugated in apical half.......... D. quadricornutus

1’. Prothorax not distinctly robust, not wider than elytra; punctation on pronotum and lateral and ventral sides of prothorax coarser, with rugose aspect; marginal anterior band on prosternum wide, transversely striate, with sparse setae; basal half of elytra with coarse and dense punctation, not coalescent, and coarsely corrugated posteriorly.......................... 2

2. Median area on pronotum vague, ill-defined ( Fig. 2a ); mesosternum separated from mesosternal process by bifurcated ridge ( Figs. 3a , 4a ); mesosternal process elevated respect to mesosternal plane; metasternum without tubercle against posterior margin of mesosternal process ( Fig. 4a )................................................................. D. major

2’. Median area on pronotum well-defined ( Fig. 2b ); mesosternum separated from mesosternal process by obsolete bi-arched ridge ( Figs. 3b , 4b ); mesosternal process slightly depressed with respect to mesosternal plane; metasternum with tubercle adjacent to posterior margin of mesosternal process ( Fig. 4b )........................................ D. orientalis sp. n.
