REMARKS

Terebratulina reevei was already reported from the Fiji region ( Bitner 2006b). This species is characterized by its coarsely ribbed ornamentation ( Cooper 1973a; Laurin 1997). The anterior commissure is from uniplicate to rectimarginate. The loop forms a broad ring slightly folded anteriorly.

Terebratulina reevei differs from T. japonica in being smaller and in having less numerous granulated ribs. It can be also easily distinguished from T. australis that has rounded outline, numerous fine ribs and small pedicle opening.
