Hołyńska, M.: A new representative of Mesocyclops thermocyclopoides-circle (Copepoda: Cyclopoida) from India

ble somite - representing in fact two independent characters - was expressed on one (the proximal) half of the somite in the ancestor of the isabellae-dadayi-dussarti-thermocyciopoides group, this feature has been conserved in isabellae-dadayi-thermocyclopoides trio, while in M. dussarti Van de Velde, 1984 the distal half has become also hairy. The caudal spinule ornamentation of the antennary basis is represented by specific pattern in all the three species in question, that makes any phylogenetic interpretation here rather difficult.
