“…Unfortunately, there has never been a phylogenetic reconstruction of crustaceans, nor any groups thereof, based on cuticular organs, despite the fact that many studies have advocated this potential and proposed some groupings based on intuitive methods (Puri, 1974;Mauchline, 1988;Tsukagoshi, 1990;Olesen, 1996;Høeg and Kolbasov, 2002). This is in stark contrast with taxonomic and phylogenetic practices in some other groups of small animals with a rigid integument, such as, for example, insects (Bousquet and Goulet, 1984;Alarie, 1995Alarie, , 1998D'Haese, 2003;Faucheux et al, 2006), tardigrades (Nichols et al, 2006), and kinorhynchs (Nebelsick, 1992;GaOrd oñez et al, 2000;Sørensen et al, 2012).…”

“…nov. makes it even easier to distinguish the species from others. Cooccurrence of glandular cell outlets type 2 in these positions is only known from three other species of Echinoderes, i.e., E. abbreviatus Higgins, 1983 (see Table 6 in present contribution), Sørensen et al, 2012, but these three species have five middorsal spines, and cannot be confused with E. charlotteae sp.…”

“…The presence of type 2 outlets in laterodorsal positions on segment 8 is more common though, and is found in six species of Echinoderes. These include ( Yamasaki and Fujimoto, 2014, Echinoderes komatsui Yamasaki and Fujimoto, 2014, Echinoderes microaperturus Sørensen et al, 2012 and Echinoderes tchefouensis (see Sørensen et al, 2012).

“…Among species of Echinoderes such a displacement is known only from E. eximus Kristensen, 1988 andE. tchefouensis Lou, 1934 (see Sørensen et al, 2012). The two species are easily distinguished from E. bookhouti though, since they lack spines in the lateral series of segments 6 and 7 (Higgins and Kristensen, 1988;Sørensen et al, 2012).…”

Studies of the kinorhynch fauna from these collections have resulted in the description of two new species, Echinoderes augustae and E. skipperae. The present contribution includes new recordings of E. augustae and E. skipperae, as well as information on two additional kinorhynch species, Echinoderes bookhouti and Echinoderes charlotteae sp. nov. The latter species is new to science and a detailed morphological description is provided. Echinoderes bookhouti was originally described from shallow water localities off North Carolina, but comparison with the type material indicates that the same species occurs in the Gulf of Mexico. Based on the new material from the Gulf, E. bookhouti is redescribed using light-and scanning electron microscopy, and new taxonomically significant characters are provided. In addition, examination of other Echinoderes types from the collections of the SmithsonianInstitution revealed that several species described before 1990 showed taxonomically significant structures, such as tubes and glandular cell outlets type 2, which were not included in their original descriptions. Hence, to ease future identification of Echinoderes species, we provide updated information about the nature and distribution of cuticular structures for a total of seven species, including E. abbreviatus, E. andamanensis, E. imperforatus, E. kristenseni, E. pennaki, E. truncatus, and E. wallaceae. 2

Meristoderes is the most recently described kinorhynch genus and has until now only accommodated its type species M. macracanthus from the Mediterranean and M. galatheae from the Solomon Islands in Southeast Asia. The present contribution is an account on the genus based on samples from the ongoing exploration of the kinorhynch fauna in coastal and subtidal waters around in the Korean Peninsula. The samples yielded no less than five new species of Meristoderes, of which four are formally described herein, whereas only diagnostic notes are provided for the fifth. The descriptions are supplemented with a key to species of the genus, and morphological notes on the organization of cephalic structures and cuticular trunk structures. New morphological findings include intrageneric variation in the composition of the terminal segment, which may have either one unpaired or two paired tergal plates. The data also show that the differentiation of a tergal and sternal plate in segment 2 varies greatly between the species. Results of the present study indicate that the genus probably holds a significant, unrecovered biodiversity, but the data also shed light on potential future taxonomic problems among genera of Echinoderidae and stress the importance of identifying additional diagnostic traits to define Meristoderes.
