Notes.

The specimens from Central Vietnam show obvious sexual dimorphism, with the tegmina of the females marked with a contrasting, incomplete, dark brown to black band at the distal 2/3 of its length, and a broad, oblique area of the same colour, or slightly paler, along the apical margin (Fig. 5D, G ). These dark markings on the tegmina are weakly visible or absent in males (Fig. 5A ). The markings of the head and thorax, however, are similar in both sexes (Fig. 5B, C, E, F ).

Biology and distribution.

The specimens were found sitting on leaves or stems on the lower vegetation (Fig. 5G ), in subtropical evergreen forest (Fig. 5H ) in at the junction of Northern Vietnam lowland rain forests, Southern Vietnam lowland rain forests, and Southern Annamites montane rain forests ecoregions, at altitude from 300 to 1,400 m. In China, the species is recorded from the Hainan Island monsoon rain forests ecoregion.

The species was previously only recorded from Hainan Island, China ( Meng et al. 2014). It is here recorded for the first time from the mainland, in Central Vietnam (Fig. 4B ).
