초록

A small cyclopoid copepod M. subtilis (Giesbrecht, 1893 ["1892"]) belonging to the genus Monothula $B{\ddot{o}}ttger-Schnack$ and Huys, 2001 was collected by using $60{\mu}m$ mesh net and firstly recorded in the epipelagic layer of the equatorial Pacific Ocean. We redescribed its morphological characteristics for both female and male, comparing with those of previous studies. Specimens of M. subtilis from the equatorial Pacific Ocean differ from those previously reported by others in terms of the length of the seta G on antenna, being much shorter than setae E and F; in the distal spine on the swimming leg 4, being longer than the length of the third segment on P4. The outer spine of the P3 enp-3 in male is slightly over the tip of conical process. The spine lengths of the distal endopods of P2-P4 for both sexes showed variations among individuals, and the proportions of spine lengths in female are higher than those in male.
