The characters defining the genus were given by LALLEMAND (1963), i.e., head broad, slightly narrower than the pronotum; frons as long as broad, not carinate, largely rounded dorsally, broadened above clypeus and strongly broader than the latter; vertex at least 4 times broader than long, excavate; tegmina at least 2.5 times longer than broad, densely reticulate; clavus closed with vein Pcu+A1 extending up to sutural margin; posterior wings almost entirely reticulate; protibiae as long as femora, sometimes slightly foliaceous; posterior tibiae with 4–6 lateral spines.

Note

Polydictya uniformis Walker, 1957 is removed from the list of species from the Indochinese region. It was described from Borneo (WALKER, 1857) and recorded from Thailand by NAGAI & PORION (1996) and BOSUANG et al. (2017) based on misidentified specimens showing a red basal area on the posterior wings, which is absent in P. uniformis .
