Motyka, Michal, 2019, Male identification, generic classification and sexual dimorphism of Micronychus pardus (Kazantsev, 2018) comb. nov. (Coleoptera: Lycidae: Calochrominae), Zootaxa 4657 (1), pp. 177-182 : 178

Tribe: CALOCHROMINI Lacordaire, 1857

Type genus: Calochromus Guérin-Méneville, 1833 .

Micronychus Motschulsky, 1861

Type species. Micronychus bimaculatus Motschulsky, 1861 (by monotypy).

Diagnosis. All Micronychus species can be distinguished from other calochromine genera by the sclerotized rodshaped internal sac ( Figs 4, 5 ) and a relatively long antennomere 3 compared to Parantis Motyka et al. 2017 species ( Fig. 3 ). Most Micronychus have a characteristic shape of the pronotum (compare Figs 7 and 8 ; Motyka et al. 2018).
