Original Paper


Nerocila recurvispina Schiödte and Meinert, 1881, a poorly known parasitic cymothoid species, is redescribed after 134 years from materials available in the National Zoological Collections of Zoological Survey of India (NZC-ZSI) collected from Hooghly River, Kolkatta. The general morphology and appendages of various life cycle stages (male, transitional, ovigerous female and juvenile) of the species are here discussed. Important characters to distinguish N. recurvispina from other species in the genus include: coxae and postero-lateral angles of all pereonites produced into narrow, apically pointed, acute and upwardly directed recurved spines; increasing the length of the recurved spines progressively from pereonite 1 to 7. Uropod rami, exopod slender, slightly longer than endopod, distal end narrowly rounded; endopod distally broader and lancelate.

The authors are thankful to Dr. K. Chandra, Director, Zoological Survey of India, Kolkata, for his encouragement and providing facilities to carry out the research work. The first author is greatly indebted to the Ministry of Environment & Forests, Govt. of India, for financial support through a Post-Doctoral Fellowship. We extend our sincere thanks to Dr. Charles Oliver Coleman, Curator of the crustacean collection, Museum für Naturkunde-Leibniz Institute for Research on Evolution and Biodiversity, Berlin, for providing quality photographs and details of the holotype of N. recurvispina, and Professor Jean Paul Trilles, University of Montpellier 2, Montpellier, France, for providing the original description of N. recurvispina. Further, we gratefully acknowledge the effort made by the two anonymous reviewers for their critical reviewing of the manuscript and making valuable suggestions for the improvement of the manuscript.
