Joal beach, Senegal ( 14°09’18”N , 16°50’00”W ), and Gambia ( Witte 1993 ) . Material. One specimen (MP-748). Figured specimens. CP-507 (valve) ( Tab. 3 ). Geographic and stratigraphic distribution. Joal beach, Senegal , and Gambia ( Witte 1993 ); Profil Nyali beach, Kenya ( Jellinek 1993 ); possibly São Pedro-São Paulo Archipelago, Brazil ; Recent. Remarks. Diagnosis follows Witte (1993) . The observed specimen differs from the holotype in general size and shape of the ventral carina, possibly representing a juvenile form of the species. Specimens identified as Triebelina cf. raripila ( Müller, 1894 ) in Keyser & Schöning (2000) are similar to T. intermedia , despite their short average length. Comparing the literature for both species ( Müller 1894 ; Yassini 1979 ; Jellinek 1993 ; Witte 1993 ; Szczechura 1998 ), it is possible to separate them based on the more subrectangular general shape and well-developed ventral carina of T. intermedia when compared to T. raripila .
