Diagnosis. Additional dorsocentral setae on presutural area present ( Fig. 24B View FIGURE 24 ).A pair of processes on male abdominal sternite VI nearly straight ( Fig. 9M View FIGURE 9 ). Epandrium roundish on posteroventral margin; anteroventral elongation broader than cercus in lateral view ( Fig. 24H View FIGURE 24 ). Female abdominal sternite VI longer than wide ( Fig. 24F View FIGURE 24 ). Oviscapt narrower than hypoproct, apically somewhat pointed in lateral view ( Fig. 24L View FIGURE 24 ).
