A New Species of the Genus Hypsibius (Tardigrada: Parachela: Hypsibiidae) from Sakhalin Island, Far East Russia

Presence of <em>Notahypsibius pallidoides</em> (Tardigrada: Hypsibiidae) in the fauna of Russia confirmed with the methods of DNA barcoding

“…Most of the published works were devoted to the European part of the territory (Biserov, 1991 and references within;Biserov, 1996aBiserov, , 1997Biserov, -98, 1999Tumanov, 1997aTumanov, , b, 2003Tumanov, , 2018Kiosya and Inshina, 2008;Kiosya, 2009). Only a few publications were devoted to the Asian part of Russia (Biserov, 1992(Biserov, , 1996b(Biserov, , c, 1998Abe, 2004;Diduszko 2005, 2006;Biserov, Pilato and Lisi, 2011). In all abovementioned publications, taxonomical data were received using the traditional morphological approach.…”

Description of a new species of Tardigrada Hypsibius nivalis sp. nov. and new phylogenetic line in Hypsibiidae from snow ecosystem in Japan

“…By having two macroplacoids, no microplacoid and septulum, and presence of cuticular sculpture, Hypsibius nivalis sp. nov. is the most similar to Hypsibius biscuitiformis Bartoš, 1960 42 , Hypsibius calcaratus Bartoš, 1935 43 , Hypsibius camelopardalis Ramazzotti & Maucci, 1983 44 , Hypsibius giusepperamazzotti Sudzuki, 1975 45 , Hypsibius macrocalcaratus Beasley, 1988 46 , Hypsibius maculatus Iharos, 1969 47 , Hypsibius morikawai Ito, 1995 48 , Hypsibius ragonesei Binda & Pilato, 1985 49 , Hypsibius roanensis Nelson & McGlothlin, 1993 50 , Hypsibius runae Bartoš, 1941 51 and Hypsibius stiliferus Abe, 2004 52 but differs from: H. biscuitiformis described from mosses in Hungary by: type of cuticular sculpture (polygonal granules, each polygon is separated, polygons form reticular network in H. nivalis sp. nov. vs. fine and regular granulation in H. biscuitiformis ), presence of cuticular bars, and different shape of second macroplacoid (rod shaped in H. nivalis sp.…”

“…The species were identified and compared with other taxa based on the previous descriptions 42 , 43 , 46 , 48 , 49 , 52 . If the information on the cuticular bars at the claws was not available either in original descriptions or drawings we assumed these structures were absent.…”

First faunistic report of limno-terrestrial tardigrades (Tardigrada Doye&#768;re, 1840) from the Maltese Islands

“…Photos were taken using a Leica Flexacam C3 digital camera installed on the above-mentioned microscope; photos were processed using Adobe Photoshop 2021. Diagnosis at the genus level was carried out using the dichotomous keys of Pilato and Binda (2010) and updates on some genera (Michalczyk and Kaczmarek 2010;Kaczmarek and Michalczyk 2017;Kaczmarek et al , 2020Gąsiorek et al 2019;Guidetti et al 2019); a provisional, general diagnosis of the species was performed with the monograph by Ramazzotti and Maucci (1983); for definitive, updated diagnosis we integrated original descriptions with updated descriptions, redescriptions, and dichotomous keys (Murray 1906;Marcus 1936;Robotti 1970;Pilato and Binda 1983;Pilato et al 1990;Nelson 1991;Nelson and McGlothlin 1993;Abe 2004;Guidetti et al 2013;Bingemer and Hohberg 2017;Nowak and Stec 2018;Stec et al 2020). Specific diagnosis also required measurements of sclerified structures, made using a micrometer, following the indications by Pilato (1981), Pilato et al (1982), Beasley et al (2008), and Kaczmarek and Michalczyk (2017).…”
