Treatment

Euonyma tugelensis ( Melvill & Ponsonby, 1897) View in CoL

Fig. 27 View Figs 26–29

Subulina tugelensis: Melvill & Ponsonby 1897: 637 , pl. 17, fig. 9 (Lower Tugela River, Natal; 14× 4 mm). Five damaged shells found at two stations inland, although similar in size to Opeas cressyi Connolly, 1922 View in CoL (type: 10.8× 2.8 mm) from central Mozambique, are not as elongated as that species. The largest (damaged) shell from the study area measures 8.2× 3.1 mm and is similar in size and proportions to Opeas durbanense View in CoL (8.7× 3.3 mm) described by Sturany (1898: 61, pl. 2, figs 42–44) from the coast of KwaZulu-Natal. Herbert and Kilburn (2004: 133) treated durbanense View in CoL as a synonym of tugelensis . Differs from the following species, as well as from common and similarly sized Allopeas clavulinum ( Potiez & Michaud, 1838) View in CoL , by the extremely narrow umbilical slit.
