Title Studies on Indian copepods 5. On eleven new species of marine cyclopoid copepods from the south-east coast of India
 
Creator Ummerkutty, A N P
 
Subject Copepods
 
Description SEWELL (1949) has pointed out that our knowledge of the cyclopoid copepods of
Indian waters, especially those inhabiting the littoral regions in association with
invertebrates and sea weeds and in which the type of existence is usually referred to
as ' semi-parasitic', is extremely scanty. The oldest account available on this little
known crustacean group in our waters is that of Thompson & Scott (1903) who,
in their supplementary reports of the faunistic survey of the Pearl Banks of Ceylon,
gave brief description of the copepods they came across. The cyclopoid copepods
they dealt with were mostly obtained by examination of washings from dredged
materials such as ascidians, sponges, corals, pearl oysters etc. Although the exact
depth at which they were caught is not given in specific instances it is presumably
from sea bottoms, at least a few fathoms deep. ' This collection of copepods have
proved to be exceedingly rich and varied, containing as it does, no less than 283
species, of which 76 are new to science while at least 10 new genera are required'
(Thomp. & Scott, loc. cit.). Of these copepods, the ' semi-parasitic' cyclopoids
were one of the richest groups; it was represented by 42 species of which 25 were
new and no less than six new genera were required to accommodate eight of the new
species. The only other exhaustive work on these tiny creatures in the Indian waters
is that of Sewell {loc. cit.) who described the species obtained during the John
Murray Expedition and also those he gathered during the long years of his valuable
service in this country in the Marine Survey of India. He recorded 44 species belonging
to this group, out of which 25 were new and 3 new genera and 2 sub-genera,
had to be created to include some of the new species. Krishnaswamy (1954) recently
reported three species from Madras coast; all the three are new to our waters
and one of them is new to science. Attention may be drawn here to ihe 2 new
genera of cyclopoid copepods that have recently been reported from this area
(Ummerkutty, 1960a and 1960b).
