The genus Mic o endipes Kie e was es ablished by Kie e in 1915 and cu en ly
comp ises o e 60 desc ibed species (F eeman and C ans on 1980; C ans on
and Ma in 1989; Ashe and C ans on 1990; Oli e e al. 1990; Zo ina 2001; Qi
and Wang 2006; Qi e al. 2014; Yamamo o and Yamamo o 2014; Haz a e al.
2016; Tang and Hi omi 2017; Song e al. 2023). In China, 18 eco ded species
ha e been desc ibed (Qi and Wang 2006; Qi e al. 2012, 2014; Song e al. 2023).
