Genus Pristiterebra Oyama, 1961 (Fig. 10C) Type species: Terebra tsuboiana Yokoyama, 1922 †; OD. Synonym: Laeviacus Oyama, 1961 (type species Terebra chibana Yokoyama, 1922; OD). Diagnosis: Shell small to medium-sized (20–65 mm). Whorls flattened to convex, with predominant pustulose or seldom cancellate sculpture. Whorl periphery shifted abapically, leading to truncated appearance of shell, with shell base abruptly constricted to short siphonal canal. Aperture wide, especially in anterior portion. Distribution: Western Pacific. Remarks: Acharacteristic truncated outline with a short siphonal canal and broad aperture allow for easy recognition of Pristiterebra among other terebrid genera. Species in Pristiterebra are nearest to the nodulose species of Neoterebra (N. tuberculosa, N. glauca, N. petiveriana), which can be recognized by the presence of a distinct subsutural groove. Some species of Gradaterebra and Partecosta have similar shell outline, but both can be differentiated from Pristiterebra by dominant axial sculpture or, rarely, complete lack of sculpture, and (in Partecosta) by generally smaller size. Included species: Pristiterebra bifrons (Hinds, 1844) 4; P. frausseni Poppe, Tagaro & Terryn, 20094 n. comb.; P. miranda (E. A. Smith, 1873) 4 n. comb.; P. pustulosa (E. A. Smith, 1879) 4 n. comb.; P. tuberculosa (Hinds, 1844) 4 n. comb.
