Dicharax (?) sonlaensis (Raheem & Schneider, 2017)

Alycaeus sonlaensis Raheem & Schneider, 2018: 1305, figs 4A-J.

Type locality.

"The earliest Miocene (Aquitanian, 23-21 Ma) Hang Mon Formation at Hang Mon in Northern Vietnam".

Remarks.

This species fits the range of morphological variation of Dicharax fimbriatus , which is an extant species from the same geographic area. However, we find it more useful to keep this taxon as a separate species due to its age. The strikingly similar appearance of an early Miocene species (Aquitanian, 23-21 Ma) to species living today indicates the high level of morphological stability of Dicharax .
