Wanat [Eastern Cape] ( BMNH) [abdominal ventrites glued on card near specimen, genitalia in glycerol—microvial pinned under specimen] . Paratypes (5 ♂ 6 ♀): R. S. A.: Eastern Cape: same labels as in the holotype (1 ♂, MWC; 1 ♂ 1 ♀, BMNH); same but date Aug.15-31.1923 (2 ♀, BMNH); same but date Sept.1923 (1 ♂ 1 ♀, BMNH); same but date Nov.1923 (1 ♂ 1 ♀, BMNH; 1 ♀, MWC); same but date Dec.1923 (1 ♂, BMNH). Three of the paratypes (2 ♂ 1 ♀) collected in September and October are teneral, with soft and deformed elytra .

Etymology. The new species is named after Pondoland, the historical area of South Africa between Transkei and KwaZulu-Natal and one of the most relevant local biodiversity hotspots, hosting many ancient apionines, including Turnerapion .
