A new species of the Genus
Namalycastis, Subfamily Namanereidinae, Family Nereidae, is being described here. Collections from Gorai creek, Mumbai, included Nereid worms previously undescribed.
Namalycastis indica is a species of
Namalycastis recorded most frequently from India. Subsequently
N. fauveli has been described from Indian waters. In addition to this
N. abiuma species group has also been observed though not recorded. As
N. indica and
N. abiuma resemble each other, there has been some confusion with regards to their occurrence from the different areas studied. The present study records the occurrence of a new species
Namalycastis glasbyi; a key is being provided to help distinguish the different species of
Namalycastis occurring in Indian waters.
