N1 - Funding Information:
We are greatly indebted to Yoshihisa Shirayama for arranging the NaGISA workshop at Seto Marine Biological Laboratory and for inviting FP and MVS to participate, and to the other workshop participants for their help collecting Dracoderes abei for the current study. We also thank Jesús Benito, Jesús Troncoso, Susumu Ohtsuka and Toyoshio Maru (Training and Research Vessel of Hiroshima University, Japan) for their help collecting Dracoderes, Jon Norenburg and William Moser for loaning us specimens from the collection of the Smithsonian Institution, and Robert P. Higgins for donating specimens of a yet undescribed species of Dracoderes. This work has been conducted with financial support of Ministerio de Ciencia y Tecno-logía, Plan Nacional de Investigación Científica, Desarrollo e Investigación Tecnológica CGL2009-08928 to FP; the SYNTHESYS Program (http:// www.synthesys.info/) financed by the European Community Research Infrastructure Action under the FP6 to MH; the research programme of KORDI with contract No. PE98583 and PE98565 to HSR; and by the Danish Natural Science Research Council (Grant No. 09-066003) to MVS.

N2 - The type species of Dracoderes, D. abei, is redescribed based on specimens from several localities in Japan and Korea, and a new species of the genus, Dracoderes gallaicus sp. nov., is described from the coast of Spain in Western Europe. The new species is distinguished by the presence of lateral accessory spines on segment 5. In addition, preliminary diagnostic notes on a yet undescribed species from the Okinawa Region, Dracoderes sp. 1, are provided. Based on new information from D. abei and D. gallaicus sp. nov., an emended genus diagnosis for Dracoderes is proposed. The study includes the first scanning electron microscopical data for species of Dracoderes, and presents for the first time detailed information about head morphology and scalid arrangement, new data about the arrangement of the neck placids, and demonstrates the presence of feebly visible nephridial pores. The new information may be of phylogenetic significance, and is expected to contribute important data for future phylogenetic analyses of the kinorhynch interrelationships.
