N1 - Funding Information:
Collection of specimens of Condyloderes shirleyi sp. nov. was made possible by Mark Schroeder and Jan Strayer, Glacier National Park, National Park Service of the USA. Sampling was conducted by R.P.H. and L. McNutt. The Smithsonian Institution is gratefully acknowledged for supporting this study during a stay of B.N. as a Postdoctoral Fellow of the Smithsonian Institution at the National Museum of Natural History, Washington D.C. We greatly appreciate technical support at their SEM lab by Susan Braden and Walter Brown and loan of specimens by Dr Jon Norenburg, Kathryn F. Ahlfeld, Cheryl Bright, and Chad Walter. In addition, we are grateful for loan of specimens by Drs Andrey Adrianov and Anastassyia Maiorova, Russian Academy of Sciences, Vladivostok, Emma Sherlock, Natural History Museum of London, and Martin V. Sørensen and Laura Pavesi, Natural History Museum of Denmark, Copenhagen; M. V. Sørensen also kindly provided SEM images of uncatalogued specimens. We appreciate the efforts of Yves Samyn, Royal Belgian Institute of Natural Sciences, Brussels, as well as of Dr Shigeyuki Yamato, Seto Marine Biological Laboratory, Japan and of Dr Chisato Murakami to check for (type) material. H.Y. gratefully acknowledges Dr Susumu Ohtsuka, Hiroshima University, for providing the opportunity to join a research cruise with R/V Toyoshio-maru and the captains and crew of this ship for sampling assistance. Raman spectra of mounting media were kindly taken by Dr Tanja Mohr-Westheide and Kirsten Born, Museum für Naturkunde Berlin. Kristine Kämpf and Antje Schwiering provided technical support in Berlin. M.D. acknowledges Prof. Dr. M. Antonio Todaro for supporting this study and providing laboratory facilities for the collection of some material examined in the present analysis. M.D. received support from the SYNTHESYS Project (http://www.synthesys.info/), financed by the European Community Research Infrastructure Action under the FP7 “Capacities” Program, to study and identify material of the Museum für Naturkunde (project number: DE-TAF-6639), FP7 ASSEMBLE grant 7th call (European Union).

N2 - The description of a new representative of the species-poor genus Condyloderes Higgins, 1969 from the Northeast Pacific (Alaska) is reported. The analyzed specimens of Condyloderes shirleyi sp. nov. showed a significant variation of numerous morphological characters, along with female-specific traits known also from other congeneric species. These findings stimulated the re-investigation of the type material of the six species of Condyloderes described so far, i.e., C. kurilensis Adrianov & Maiorova, 2016, C. megastigma Sørensen, Rho & Kim, 2010b, C. multispinosus (McIntyre, 1962) Higgins, 1969, C. paradoxus Higgins, 1969, C. setoensis Adrianov, Murakami & Shirayama, 2002, and C. storchi Higgins, 2004 in Martorelli & Higgins, 2004. Our study allowed to reveal various morphological novelties and to emend the diagnosis of these species and of the genus Condyloderes. Furthermore, our analysis led to synonymize C. megastigma with C. setoensis. The results of our investigation about the significant variation in C. shirleyi sp. nov. raise a wider question on species identity within Kinorhyncha, underscoring the necessity, if possible, to describe new species from a higher number of specimens and to concentrate on the morphological variation of the going-to-be-described species.
