Comparative notes. Valleriola javanica is most similar to V. bui sp. nov. and V. buenoi ; see comparative notes under those species.

Remarks. This species is widely distributed in Southeast Asia and China and is here newly reported from Laos.

Distribution: J. Polhemus & D. Polhemus (2012) listed the range of this species as including Indonesia, Malaysia, Thailand, Burma and China ( Hong Kong). To this we add Laos and additional provinces in China (Yunnan, Hainan, Guangxi, and Taiwan) ( Fig. 61 ).
