Abstract.—One newgenus (Carvalhygia) and three new species (C carvalhoi, C. milzae,
and C. nigra) collected in the Philippine Republic are described in the tribe Colpurini
(Coreidae). Habitus view illustrations and drawings ofthe male and female genitalia are
provided to help distinguish these taxa.
