A new leafminer on grapevine and Rhoicissus (Vitaceae) in South Africa within an expanded generic concept of Holocacista (Insecta, Lepidoptera, Heliozelidae).

ABSTRACT: A grapevine leafminer found recently in table grape orchards and vineyards in the Paarl region (Western Cape, South Africa) is described as Holocacistacapensis sp. n. It has also been found on native Rhoicissusdigitata and bred on that species in the laboratory. It is closely related to Holocacistasalutans (Meyrick, 1921), comb. n. (from Antispila), described from Durban in KwaZulu-Natal, but widespread in southern Africa and a native leafminer of various Vitaceae: Rhoicissustomentosa, Rhoicissusdigitata, Rhoicissustridentata and Cissuscornifolia.
