“…Perinereis cultrifera and 9. Scololepis squamata have been reported earlier in Vasishta and Godavari estuary [17,18]. The same species was reported in Indian estuaries including Cochin estuary [19,12,20]; Zuari estuary [13,14]; Cochin backwater [15]; Karwar estuary [16]; Pudhucherry estuary [21] and various estuaries in Tamilnadu [22].…”

Background: Polychaetes are an important component of the estuarine and mangrove ecosystem especially in fisheries perspective. The polychaete fauna of the Manakkudy estuary barmouth and mangrove was examined for species composition and taxonomic classification. A total of 27 species belonging to 16 genera under 12 families were collected. Results: Of these 27 species, 16 are new records to Manakudy estuary. Out of which, those coming under the group Errantia were dominant (9 species) when compared to Sedentaria group (7 species). Among the 12 families identified, the species diversity of Nereidae and Capitellidae were found to be high. Conclusions: Salinity and nature of substrata, two main factors which govern the distribution of polychaetes, are also given along with species description.

ABSTRACT. A cladistic analysis and taxonomic revision of the Namanereidinae (Nereididae: Polychaeta) is presented. The cladistic analysis utilising 39 morphological characters (76 apomorphic states) yielded 10,000 minimal-length trees and a highly unresolved Strict Consensus tree. However, monophyly of the Namanereidinae is supported and two clades are identified: Namalycastis containing 18 species and Namanereis containing 15 species. The monospecific genus Lycastoides, represented by L. alticola Johnson, is too poorly known to be included in the analysis. Classification of the subfamily is modified to reflect the phylogeny. Thus, Namalycastis includes large-bodied species having four pairs of tentacular cirri; autapomorphies include the presence of short, subconical antennae and enlarged, flattened and leaf-like posterior cirrophores. Namanereis includes smaller-bodied species having three or four pairs of tentacular cirri; autapomorphies include the absence of dorsal cirrophores, absence of notosetae and a tripartite pygidium.
