Vervoort, 1963 b, p.88-89) rejects Johnson's (1938) subdivision of the Eucalanus elongatus complex into a number of separate species and subspecies, basing the conclusion largely on material from the seas of the East Indies. Part of that material possessed characters intermediate between those used by Johnson to discriminate between his various species and subspecies. This made strongly doubt the value of the taxons institued by Johnson. Though he believes that the various characteristics used by Johnson to established the taxons in his 1938 paper are in need of a critical revision, the occurrence of two separate species, Eucalanus bungii Giesbrecht, 1892 and Eucalanus inermis Giesbrecht, 1892, besides Eucalanus elongatus (Dana, 1849), seems to be beyond doubt. Nomenclatural difficulties might arise from the fact that Dana's figure and description of Eucalanus elongatus are inadequate to decide to which of the various taxons of the E. elongatus complex it really refers. The geographical distribution is limited here to the Indo-Pacific form, sensu stricto. The varieties are established according to the rank of the species. The forms reported by the authors under this denomination, between brackets, should presumably correspond to Eucalanus hyalinus. Khelifi-Touhami & al., 2007 (p.327, Table 1) note the two species E. elongatus and E. hyalinus from the algerian coast, the first needs confirmation. After us, this species is noted for the first time in the Red Sea by El-Sherif & Aboul Ezz (2000, p.72) and need confirmation. For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value of the mandibular gnathobase = 200. Timonin (1971, p.282) considers the trophic interrelations in the equatorial and tropical Indian Ocean, and divides the plankters into 6 trophic groups from the litterature and the results of studies of mouth-parts structure and intestine content. This species is a coarse-filter feeder.
