1993 Triebelina cf. intermedia Witte. Jellinek , p. 108, tf. 2, fig. 43.

?2000 Triebelina cf. raripila (Müller) . Keyser & Schöning, p. 569, pl. 2, figs. 27−32.

Holotype. S375 ( Witte 1993).

Type locality. 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 .
