Abstract. The flower bug genus Physopleiirella Renter 1884 ofsoutheastern Asia
is revised. Six species are recognized from this region, including three new species: P.
malayana, n. sp., P. nigrifemova, n. sp., and P. striata, n. sp. Physopleurella armatci
Poppius 1909, P. pessoni Carayon 1956, and P. flava Carayon 1956 are recorded
from southeastern Asia for the first time. Keys are provided to distinguish species.
