First record of Leptorhaconotus Granger (Hymenoptera: Braconidae) from South Africa, with the description of a remarkable new species and a discussion of the subfamilial placement of the genus

Leptorhaconotus marshi sp. n. from South Africa is descriptionbed and illustrated. This is the first record of the genus beyond Madagascar. The new species is unique in that the ovipositor sheaths are broadened and fused along the midline to form a flag-like appendage that does not cover the ovipositor. The systematic placement of Leptorhaconotus Granger is discussed on the basis of new data on ovipositor structure and internal anatomy.
