Paradasys lineatus Rao, 1980

Records from India. ANDHRA PRADESH: Visakhapatnam (Waltair), Krishnapatnam beach—Rao (1980a); ODISHA: Gopalpur—Rao (1989); GENERAL RECORD: Naidu & Rao (2004).

Habitat. Marine, intertidal; Medium sand, 10 cm below surface.

Remarks. The structure of the spermatozoa, described as a filiform cell with a corkscrew head, cast doubt on the affiliation of the Indian specimens to the genus Paradasys ( Ruppert & Shaw 1977; Guidi et al. 2017). The shape, size (up to 800 µm in total length), organization of the reproductive system, and structure of the spermatozoa would suggest their affiliation to the genus Cephalodasys instead. Future research could provide support to our working hypothesis. In the meantime we consider the taxon to be species inquirenda (i.e., a species of doubtful identity needing further investigation).
