Distribution. Indonesia ( Fischer 1921 ; Fischer 1927 ; van der Vlerk 1931 ; Marshall 1994 ; Swarko & Sufiati 1994 ), Philippines ( Poppe 2008 ). Geological age. Pliocene ( Fischer 1921 ; van der Vlerk 1931 ; Marshall 1990; Swarko & Sufiati 1994 ). Remarks. The genus Triforis is of feminine gender, thus the name should be Triforis serana . Fischer introduced the name for the first time in his 1921 paper on the Pliocene fauna of Seran in the Moluccas . A footnote points to the differences from Triphoris granulata A. Adams & Reeve, 1850 . Despite minimal, this comparative statement is here considered a valid introduction of the name. In 1927, Fischer described the species more thoroughly in his revision on the Pliocene and Quaternary of Timor and illustrated it, but despite its mention of Triforis seranus “ spec. nov. ”, the 1921 should be considered as the year of publication for this species.
