Martin Kolner sent us photos of two beautiful cicadas from Sapa Vietnam.
The first one
belongs to the genus Angamiana, and I think it is an Angamiana floridula might be a Proretineta vermacula (Chou& Yao, 1985), according to David Emery.
The second cicada belongs to the genus Tosena.
According to David, the Tosena is “likely to be T.fasciata (melanoptera does not have orange anywhere), even though the dorsal markings are pretty bleached”.
