DIAGNOSIS

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.

SPECIES INCLUDED FROM JAVA

Polydictya bhaskarai sp. nov.

Polydictya javanensis Schmidt, 1910

Polydictya rufifrons Schmidt, 1910

NOTE

Polydictya robusta Gerstaecker, 1895 is removed from the list of species Java. It was recorded from this island by NAGAI & PORION (1996) based on an erroneous synonymy with P. javanensis Schmidt, 1910 . Polydictya javanensis is reinstated as a valid species in the present paper and both species are illustrated, including their type specimens and terminalia.
