PLANKTONIC CYCLOPOID COPEPODS FROM SMALL PONDS IN KYUSHU, JAPAN .1. SUBFAMILY EUCYCLOPINAE WITH DESCRIPTIONS OF MICRO-CHARACTERS ON APPENDAGES

Four cyclopoid copepods of Eucyclopinae, Macrocyclops albidus, Eucyclo ps cf. serrulatus, E. cf. speratus and Tropocyclops prasinus, are desc ribed from small ponds in Kyushu. Special attention was paid to spinul es on the appendages. Macrocyclops albidus and E. cf. serrulatus have some differences in those spinules from European forms described in pr evious studies. The Japanese E. serrulatus-speratus group probably con sists of more than two species. Tropocyclops prasinus is identical to the description by Gurney (1933) in micro-characters but differs in se tal lengths of the legs.
