Diagnosis of female

(Fig. 17). Similar to male (Fig. 16), with the following exceptions. The length of the only known female specimen is 28.0 mm (except of pygidium), while the length of males varies between 21.5-24.5 mm. Anterior margin of clypeus only very feebly upturned, nearly flat. Antennal club pentamerous. Outer margin of anterior tibia distinctly tridentate. Upper apical spur of metatibia broad, flattened, blunt apically. Tarsal claws of all pairs of legs equal in length.

Collecting methods.

The female specimen was collected at light.

Diagnosis.

An easily recognizable Polyphylla (Granida) species because of its maculate elytra. Antennomere 3 long and slender, more than three times longer than antennomere 2. Basal margin of pronotum is almost straight against the scutellum, while convex in other Granida species. It is most likely to be confused only with some Polyphylla (Granida) jessopi specimens bearing the same maculate elytral pattern. Polyphylla (Granida) phongsali in average larger than Polyphylla (Granida) jessopi (the length of males varies between 21.5-24.5 mm versus 18.5-20.0 mm in Polyphylla (Granida) jessopi ). Male genitalia as in Figs 18-19.

Distribution.

Northern Laos.

Remarks.

The species was originally described from a single male. Here we recorded eight additional specimens from northern Laos (Fig. 20). The specimens with altitude data were collected between 1350-1900 m a.s.l.
