KERALA : Fort Kochi (Cochin), Karunagapally—Govindankutty & Nair (1969 , 1972) as Pleurodasys megasoma ; GENERAL RECORD: Naidu & Rao (2004) . Habitat (as in Indian records). Marine, intertidal, subtidal; fine and medium grained sediment, less frequently in intertidal zone, more widespread in submersed sand. Distribution. North Sea; Mediterranean Sea; India (Arabian Sea). Remarks. The Indian specimens are reported to bear a pair extraordinary organs ("lateral feet" of Naidu and Rao), each comprised of three adhesive tubes, while in the European specimens, these organs are composed of four tubes ( Marotta et al ., 2008 ). This difference, and the geographic distance from the type locality, call for a better morphological comparison between Indian and European populations. Ideally, such comparisons should also include genetic data as well as specimens from conspecifics, e.g., P. incomptus Todaro, Dal Zotto, Bownes & Perissinotto, 2017 described from South Africa (see Todaro et al . 2017 ). We note positively that for some of the Indian populations information on seasonal dynamics are available ( Govindankutty & Nair 1972 ). This type of information is much needed but rarely available for gastrotrich species.
