Comment. Nazeris dayaoensis (in Hu et al. 2012: 36, Figs 1–6 ) is similar to N. latilobatus Assing, 2016 ( Assing 2016: 307, Figs 8–12 ; Hu & Qiao 2019: 432, Figs 7–11 ) in external and male sexual characters, but can be separated by the ventral process of aedeagus narrow, constricted to the sharp apex in ventral view.

Distribution and habitat. Nazeris dayaoensis is known only from the Dayao Mountains in middle Guangxi. The specimen was collected by sifting leaf litter at altitudes of 1,200 –1,800 m.
