Abstract: Six new species of the genus Heisonyx Marshall, 1947 from South Africa (H.
barclayi sp. nov., H. danielssoni sp. nov., H. fuscus sp. nov., H. giustocaroli
sp. nov., H. hexarthrum sp. nov., and H. jelineki sp. nov.) are described,
illustrated and keyed. The genus is redescribed and its taxonomic position is
briefly discussed. Heisonyx and Lalagetes Schoenherr, 1842 are newly
transferred from the Oosomini Lacordaire, 1863 to the Embrithini Marshall,
1942. Male and female genitalia of Heisonyx are studied and illustrated for the
first time.
