Genus Sinometrius Wrase & Schmidt, 2006 Ŗ灼步Ƥ属

Remarks. Sinometrius can be separated from the Nearctic genus Metrius by 1) dorsal and ventral surface sparsely punctate and setose; 2) numerous setae irregularly inserted at middle of abdominal sternites, sternite VII at least covered with six preapical setae; 3) antennomeres 1–4 sparsely covered with long setae, not confined to apices; 4) submentum with two pairs of setae laterally; 5) pronotum laterally with broad gutter rather than marginal bulk; 6) mesotibia not distinctly brushed in apical two-thirds; 7) gonopods furcate apically (Wrase & J. Schmidt, 2006). It can be distinguished from the fossil genus Kryzhanovskiana Kataev & Kirehtshuk, 2019 by 1) the smaller and narrower pronotum; 2) the shorter mandibles; 3) well-developed eyes; 4) prosternal process with well-developed apical part; 5) elytral surface with fine, somewhat sparse punctation ( Kataev et al., 2019).
