A new species of the long-tailed wasp genus Euurobracon Ashmead (Hymenoptera, Braconidae, Braconinae) from Java, Indonesia, is described and the type species redescribed.

A new species, Euurobraconbhaskarai Quicke, sp. nov., from West Java, Indonesia, is described, illustrated and differentiated from other members of the genus. It is closely related to the type species of the genus, E.yokahamae Dalla Torre, 1898, which is known from China, India, Japan, Laos, South Korea and Thailand. Euurobraconyokahamae is redescribed and illustrated for comparative purposes. The two species are separable mainly on colouration, but differ markedly based on their mitochondrial gene sequences (cytochrome c oxidase I, cytochrome b and 16S rDNA). The slower-evolving nuclear 28S rDNA and elongation factor 1-alpha did not differentiate E.bhaskarai sp. nov. from E.yokahamae, but consistently split Euurobracon into two species groups.
