Baiyuerius zuojiang View in CoL -species group

Diagnosis. Males of zuojiang- group species can be identified by 1) patella about 2 times wider than long, patellar apophysis strong and cylindrical, with blunt end ( Figs 27C View FIGURE 27 , 31C View FIGURE 31 ; figs 3C, 5C, 6C in Zhao et al. 2023; fig. 5G in Luo et al. 2023); 2) lateral tibial apophysis short or expanded, situated near the dorsal margin of tibia ( Figs 27C View FIGURE 27 , 31C View FIGURE 31 ; figs 3C, 5C, 6C in Zhao et al. 2023; fig. 5G in Luo et al. 2023); 3) cymbial furrow short, nearly triangular in shape, with indistinct dorsal margin ( Figs 27C View FIGURE 27 , 31C View FIGURE 31 ; figs 3C, 5C, 6C in Zhao et al. 2023; fig. 5G in Luo et al. 2023); 4) process of dorsal margin of conductor without basal stalk, serrated and strongly sclerotized ( Figs 27B View FIGURE 27 , 31B View FIGURE 31 ; figs 3B, 5B, 6B in Zhao et al. 2023; fig. 5F in Luo et al. 2023); 5) dorsal apophysis of conductor extremely long and with large basal lamellar ( Figs 27D, E View FIGURE 27 , 31D, E View FIGURE 31 ; figs 3B, 5B, 6B in Zhao et al. 2023; fig. 5F in Luo et al. 2023); 6) tegular sclerite short and approximately right-trapezoid-shaped ( Figs 27B View FIGURE 27 , 31B View FIGURE 31 ; figs 3B, 5B, 6B in Zhao et al. 2023; fig. 5F in Luo et al. 2023); 7) median apophysis small and strongly sclerotized ( Figs 27B View FIGURE 27 , 31B View FIGURE 31 ; figs 3B, 5B, 6B in Zhao et al. 2023; fig. 5F in Luo et al. 2023). Females can be identified by 1) epigynal teeth absent ( Figs 29A View FIGURE 29 , 33A View FIGURE 33 ; figs 1A, 7A in Zhao et al. 2023; fig. 5C in Luo et al. 2023); 2) posterior epigynal pocket obviously wider than long ( Figs 29A View FIGURE 29 , 33A View FIGURE 33 ; figs 1A, 7A in Zhao et al. 2023; fig. 5C in Luo et al. 2023).
