Abstract
A new species of Lygistorrhina (Lygistorrhina) Skuse, 1890, Lygistorrhina woodi sp. nov., is described. The specimen was dissected from an alcohol-preserved flower of Ceropegia aristolochioides ssp. deflersiana Bruyns (Apocynaceae, Asclepiadoideae, Ceropegieae) stored in the Kew herbarium. This is the first occurrence of the lygistorrhine gnats in a hot, semi-arid climate. A key to all known species of the subgenus Lygistorrhina (Lygistorrhina) is provided.

Lygistorrhina woodi, sp. nov.
Diagnosis. Lygistorrhina woodi sp. nov. is unique among other species of the subgenus in having compound eyes with very short interommatidial setae, proboscis relatively short; costa reaching only ~½ of distance between r5 and M1; and tergite 9 of male terminalia with shallow sinus basally and very small arms of apodeme.
Etymology: the specific epithet is a patronym for John R. I. wood, a prominent botanist, who inadvertently collected the holotype of the species.
