Synonyms[1]
  • Brachytoma vexillum Habe & Kosuge, 1966
  • Inquisitor vexillium (Habe & Kosuge, 1966)

R.N. Kilburn proposed in 1989 Brachytoma vexillum Habe & Kosuge, 1966 as a synonym of Ptychobela suturalis (Gray, 1838)[2]

The epithet vexillium was probably a misspelling in the original text, but was not indicated as such. Therefore, it takes priority over vexillum, published five-month later and repeated later by some authors.

Description

edit

The length of the shell attains 46.5 mm, its diameter 14.5 mm.

Distribution

edit

This marine species occurs in the South China Sea, off the Philippines and Japan; also off Australia (Northern Territory, Queensland, Western Australia).
