Paracis spinosa (Thomson & Henderson, 1906)
Acis spinosa Thomson & Henderson, 1906: 77–78, pl. 5, fig. 11 (Andamans).
Opinion: This species does occur in the region, but its true identity is unknown.
Justification:
Literature analysis: Originally described as Acis spinosa, only a branch fragment was illustrated so the species is essentially unidentifiable. Kükenthal (1924) reassigned the species to the genus Paracis . Rao & Devi (2003) just listed it under the original name.
