Megalestes australis Karube, 2014: 73–76, fig. 3 [Bach Ma National Park, Thua Thien Hue, Vietnam]; Phan & To 2018: 1–6, figs. 7–9, 14–18, 25–27 [Tay Giang, Quang Nam; Bach Ma National Park, Thua Thien Hue, Vietnam].
This is a relatively large Vietnam endemic species, somewhat resembling M. heros and M. distans in the shape of appendages but unique in the shape of the genital ligula with relatively long and thin horns (Fig. 4a, n). Its species status was supported by molecular analyses (Fig. 7).
