Genus Atrocrates Koch, 1956

Atrocrates Koch, 1956: 82 .

Type species. Trigonopus platyderus Mulsant and Rey, 1853 (by original designation).

Revised diagnosis. This genus can be distinguished from other representatives of the trigonopoid Platynotina by the following character combination: antennomeres from 7th to 11th transverse; medial lobe of mentum hexagonal, narrowing towards apex, with median keel ( Fig. 4 C); punctation of pronotal disc invisible or fine ( Fig. 4 B); pronotal base straight or slightly sinusoidal, anterior and basal borders of pronotum complete, lateral border of pronotum widened basally and relatively broad ( Fig. 4 B); elytral base straight or slightly sinusoidal ( Fig. 4 F); and protibiae widened towards apex ( Fig. 4 E).

Notes. The most recent identification key to the species of Atrocrates was published by Iwan (1998c), and includes most of the previously named species, except: A. bellamyi Iwan, 1999 , A. coconatae Kamiński, 2011 , A. gansbaaiensis Iwan and Ferrer, 2000 , A. galbasi Iwan 2016 ; A. matthewsi Iwan, 2016 ; A. medvedevi Iwan and Ferrer, 2000 , A. nudus Iwan and Ferrer, 2000 , A. robertsoniensis Iwan, 1999 . The same author recently proposed a subdivision of this genus into species groups ( Iwan 2016).
