Two dichelesthiid copepods from Madras fish

Abstract

In the course of studies of copepods parasitic on the market fishes of South India two of the most valued fishes, Scomberomorus commersoni and Stromateus niger, were found infested by large numbers of the blood-sucking parasites, Pseudocycnus armata Bas-sett-Smith and Lernanthropus konigii Steenstrup & Lutken. In the present paper the description of Pseudocycnus armata, which was first recorded by Bassett-Smith from Bombay and later by Kirtisinghe from Ceylon, is confined to a more accurate account of the appendages than has been given by these authors, while Lernanthropus konigii, which has not been recorded since it was established in 1861, is fully described.
