Revision of the genera of the subfamily Sigalphinae (Hymenoptera: Braconidae), including a revision of the Australian species

A key to all known genera of the Sigalphinae (Braconidae) is given and all genera are described and fully illustrated. Two new genera from the Australian region and one from the Afrotropical region are described: Notosigalphus gen. nov. (type species: Sphaeropyx conjugator Turner, 1917), Aposigalphus gen. nov. (type species: Aposigalphus tessi spec. nov.), and Malasigalphus gen. nov. (type species: Malasigalphus petiolaris spec. nov.). Keys to the Australian and Palaearctic species of Sigalphinae are given. The new tribe Afrocampsini is proposed for the Afrotropical genera Malasigalphus gen. nov. and Afrocampsis van Achterberg & Quicke, 1990. Sigalphus hunanus You & Tong, 1991, and S. anonis You & Zhou, 1991, are synonymized with S. irrorator (Fabricius, 1775).
