  author={Birger Neuhaus and Fernando Pardos and Martin Vinther S{\o}rensen and Robert P. Higgins},
Four new species of Centroderes are described from the Northwest Atlantic Ocean based on light microscopical observations of 153 adult and 26 juvenile specimens and on SEM investigations of 54 adult and 3 juvenile specimens. Centroderes barbanigra n. sp. and C. bonnyae n. sp. can be distinguished from all other species by the existence of a short lateroventral tube on segment 7. The latter species can be separated from the former by an acicular spine in the lateral accessory position on segment…

New species of Semnoderidae (Kinorhyncha: Cyclorhagida: Kentrorhagata) from the Gulf of Mexico

A comparison of these three genera with the specimens recorded in the present study indicates that Antygomonas should be considered as closely related with Sphenoderes and Semnoderes, but it also suggest that A. gwenae could represent a separate lineage within Semnoderidae, and that the species should be reassigned to a new genus.

Two new species of Echinoderes (Kinorhyncha, Cyclorhagida), E. romanoi sp. n. and E. joyceae sp. n., from the Gulf of Mexico

Meiofauna sampling on the continental shelf of the northern Gulf of Mexico has resulted in numerous new species of kinorhynchs from the shelf sediment, two of which are described in detail in this paper and are unique in their spine, tube, and glandular cell outlet patterns.

New species of Echinoderes (Kinorhyncha: Cyclorhagida) from Spitsbergen, with additional information about known Arctic species

The results suggest that Arctic Echinoderes species have a circum-Artic distribution and Morphological analysis indicates that the occurrence of tubes may show intraspecific variation.

Echinoderes pterus sp. n. showing a geographically and bathymetrically wide distribution pattern on seamounts and on the deep-sea floor in the Arctic Ocean, Atlantic Ocean, and the Mediterranean Sea (Kinorhyncha, Cyclorhagida)

Abstract Kinorhynchs rarely show a wide distribution pattern, due to their putatively low dispersal capabilities and/or limited sampling efforts. In this study, a new kinorhynch species is described,

Kinorhynch diversity in the southern Gulf of Mexico and a description of Dracoderes chaac sp. nov.

This study focused on the non—echinoderid members of the Phylum Kinorhyncha, many of which are rare or restricted to only a few locations, and identified 136 species reported from earlier collections in the northern Gulf of Mexico on the U.S. continental shelf.



Redescription, morphology, and biogeography of Centroderes spinosus (Reinhard, 1881) (Kinorhyncha, Cyclorhagida) from Europe

The study reveals that the two known species of the kinorhynch genus Centroderes, C. spinosus and C. eisigii Zelinka, 1928 represent male and female of C.spinosus comb.

Taxonomic Study of the Kinorhyncha in Japan. III. Echinoderes sensibilis n. sp. (Kinorhyncha: Cyclorhagida) from Tanabe Bay

Abstract A new species of echinoderid kinorhynch, Echinoderes sensibilis, is described and illustrated using light and electron microscopy. The specimens were collected from masses of the red algae

Wollunquaderes majkenae gen. et sp. nov.—a new cyclorhagid kinorhynch genus and species from the Coral Sea, Australia

A new kinorhynch genus and species, Wollunquaderes majkenae gen. nov., is described from a locality in the Coral Sea, southeast of the Great Barrier Reef, Australia, and displays several traits found in species of Antygomonas and/or Semnoderes, but also characters that otherwise are considered unique for taxa of Centroderidae.

On the genus Dracoderes Higgins & Shirayama, 1990 (Kinorhyncha: Cyclorhagida) with a redescription of its type species, D. abei, and a description of a new species from Spain

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.

A New Species of Condyloderes (Cyclorhagida, Kinorhyncha) from Korea

A new kinorhynch species, Condyloderes megastigma sp. nov., is described from the Korea Strait. The new species is characterized by the presence of 16 placids with either eight, four, or two knobby

Redescription of Cateria gerlachi (Kinorhyncha, Cyclorhagida) from Sri Lanka and of C. styx from Brazil, with notes on C. gerlachi from India and C. styx from Chile, and the ground pattern of the genus.

Detailed morphological data is reported for species of Cateria, including variability within populations, a female and a male life-history stage, as well as moulting of an adult stage to another adult stage.

Taxonomic Study Of The Kinorhyncha In Japan. Ii. Condyloderes Setoensis, A New Species (Kinorhyncha : Cyclorhagida) From Tanabe Bay

A new species of centroderid kinorhynchs, Condyloderes setoensis, new species, from muddy sediment at Tanabe Bay, Honshu Island, is described and illustrated using light and electron microscopy.

Systematics of the amphiatlantic Microphthalmus‐listensis‐species‐group (Polychaeta: Hesionidae): Facts and concepts for reconstruction of phylogeny and speciation

This study uncovered distinct differences between the species in their internal organization and found that within population character variability is significantly lower in several features of M. carolinensis than in the same characters of the other two species.
