1931 Vesicomya guineensis sp. nov.; Thiele and Jaeckel 1931: 229, pl. 9: 102.

1970 Vesicomya (Vesicomya) guineensis Thiele and Jaeckel, 1931 ; Boss 1970: 71–72, figs. 5–6, 18–19.

2009 Wareniconcha guineensis ( Thiele and Jaeckel, 1931) ; Cosel and Olu 2009: 2362, figs. 11–14, 29G–H.

Material.— Five specimens from the Pliocene of Liog-Liog Point ( NMNS PM 28197–28201 ). NMNS PM 28197 : L = 46.9 mm, H = 35.5 mm; NMNS PM 28199 : L = 37.0 mm, H = 30.4 mm .

Remarks.— Cosel and Olu (2009) documented shell shape and hinge variability for Wareniconcha guineensis and the specimens from Liog-Liog Point fall well within this variability. In particular, specimen NMNS PM 28199 has a very similar outline as the Wareniconcha guineensis syntype stored at the Museum für Naturkunde, Berlin (Moll.101.600). Stratigraphic and geographic range.—Late Pliocene: Leyte, Philippines. Recent: west coast of tropical Africa.
