5. Macroglossum troglodytus( formerly as M. insipida )

This & M. neotroglodytus are near identical.
M. neotrogldytus is stated to a duller grey ground colour.
The only noticeable difference is in M. trigldytus the curved antemedial band is almost uniformly dar.
In M. neotriglodytus the antemedial band is edged dark on its inner margin.

Judging from this website 8 should be correct as Macroglossum neotroglodytus.
