Diagnosis.
Baiyuerius pindong sp. nov. can be distinguished from the other congeners of this new genus as follows: 1) cymbial furrow less than 1/2 the length of cymbium (Fig. 3C View Figure 3 ) vs. more than 1/2 in others (Figs 5C View Figure 5 , 6C View Figure 6 ); 2) cymbial base with two hypophyses (Fig. 3C View Figure 3 ) vs. only one in others (Figs 5C View Figure 5 , 6C View Figure 6 ); and 3) lateral tibial apophysis concave and large, wider than long (Fig. 3C View Figure 3 ) vs. finger-like, longer than wide in others (Figs 5C View Figure 5 , 6C View Figure 6 ).
