  • The neustonic calanoid copepods Pontella securifer Brady, 1883 and P. sinica Chen and Zhang, 1965 are first recorded in Korea. These species occur in high temperatures over $23^{\circ}C$ and in a range of salinity from 26.6 to 31.2 psu. We provide full descriptions of the two species and discuss their zoogeography.

  • Labidocera pavo Giesbrecht, 1889 and L. sinilobata Shen and Lee, 1963, belonging to the detruncata group in the genus Labidocera were collected from the southwestern coastal waters of Korea, using a Norpac net (0.2 mm mesh size). Labidocera sinilobata, known to be endemic species in estuary of Chinese rivers, is the first record in Korean waters. In Chinese waters, this species has only been briefly documented and illustrated. In the study, their morphological characteristics were fully redescribed with careful examination of the fine epidermal structure using a SEM (Scanning Electron Microscope) in addition to their illustrations and compared with species of the detruncata species-group.

  • To understand physical structures in the Korean waters, we investigated the spatio-temporal distribution of Pontella species known as indicator species of water mass using a David-Hempel neuston net from April 2002 to March 2003. Five Pontella species (P. chierchiae Giesbrecht, P. fera Dana, P. latifurca Chen and Zhang, P. securifer Brady and P. sinica Chen and Zhang) were found. Their abundance increased from May to October with increasing the surface water temperature. Pontella chierchiae predominantly appeared in the whole areas while P. latifurca scarcely occurred in coastal waters. The other three species (P. fera, P. securifer and P. sinica) were rarely found in the South Sea of Korea on August to September. We suggest that P. securifer and P. fera as oceanic species can play a role in an indicator species of the Tsushima Warm Current while P. sinica as Chinese coastal species is affected by the diluted waters of the Yantze River. We also provide re-description of the three species (P. chierchiae, P. fera and P. latifurca) insufficiently described and discuss their zoogeography.

  • Neustonic calanoid copepods were collected at the South Sea of Korea using a David-Hempel neuston net. Four Pantel/apsis species (P. armata Giesbrecht, P. rega/is Dana, P. vil/asa Brady and P. yamadae Mori) were identified and the former three species were first recorded in the Korea. We present redescription of the four species with SEM micrographs of female genitalia. Female genital structure is species-specific and can be very useful for species classification in the genus Pantel/apsis. Also we discuss zoogeography of Pantel/apsis species and provide with a key to the species hitherto known in the Korean waters.
