USGS 25734, Vanuatu, Espiritu Santo Island, Late Pleistocene, 1 specimen, USNM 100175; Ryukyu Islands, Okinawa, Horseshoe Cliffs, 1 km NNW Onna Village (26?0'N, 127?0'54"E), 67-79 m, six specimens, USNM 87712, 88380, 88382, 88383, and 100674. Distribution. Late Pleistocene: Vanuatu. Holocene: southern Japan, Philippines, Indonesia, Wallis and Futuna, New Caledonia, Kermadec Islands, 18-441 m. Remarks. This is the smallest in the Truncatoflabellum species, obtaining a GCD hardly ever greater than 5 mm, but capable of numerous apical regeneration (Fig. 2A, leading) resulting in coralla as long as 17.5 mm.
