Abstract Three new gastrotrich species of the genus Tetranchyroderma are described sublittoral sandy bottoms of the Yellow Sea and Jeju Island in South Korea. Tetranchyroderma aethesbregmum sp. nov., which has a dorsal cuticular armature with pentancres only, is characterized by the peculiar shape of the head with a median trapezoidal lobe flanking three pairs of papillae. Tetranchyroderma megabitubulatum sp. nov. is clearly differentiated from other pentancrous species by the character combination of three pairs of cephalic tentacles, a pair of long dorsolateral adhesive tubes, and paired ‘foot’ ventral adhesive tubes. Tetranchyroderma insolitum sp. nov. is the only species possessing cuticular armature with tetrancres and triancres mixed, and also characteristic in having an earlobeprotrusion at the posterolateral corners of head. Key words: Description, Gastrotricha, marine, South Korea, taxonomy Introduction The serial faunal studies on macrodasyidan gastrotrichs have been carried out in Korea, since Chang et al. (1998a) first recorded two Thaumastoderm species, T. copiophorum and T. appendiculatum. A total of 16 species from six genera in two families, Planodasyidae Rao & Clausen, 1970 and Thaumastodermatidae Remane, 1926 have been recorded from the Korean coast so far (Chang et al. -
Gastrotricha of Sweden – Biodiversity and Phylogeny
Gastrotricha of Sweden – Biodiversity and Phylogeny Tobias Kånneby Department of Zoology Stockholm University 2011 Gastrotricha of Sweden – Biodiversity and Phylogeny Doctoral dissertation 2011 Tobias Kånneby Department of Zoology Stockholm University SE-106 91 Stockholm Sweden Department of Invertebrate Zoology Swedish Museum of Natural History PO Box 50007 SE-104 05 Stockholm Sweden [email protected] [email protected] ©Tobias Kånneby, Stockholm 2011 ISBN 978-91-7447-397-1 Cover Illustration: Therése Pettersson Printed in Sweden by US-AB, Stockholm 2011 Distributor: Department of Zoology, Stockholm University Till Mamma och Pappa ABSTRACT Gastrotricha are small aquatic invertebrates with approximately 770 known species. The group has a cosmopolitan distribution and is currently classified into two orders, Chaetonotida and Macrodasyida. The gastrotrich fauna of Sweden is poorly known: a couple of years ago only 29 species had been reported. In Paper I, III, and IV, 5 freshwater species new to science are described. In total 56 species have been recorded for the first time in Sweden during the course of this thesis. Common species with a cosmopolitan distribution, e. g. Chaetonotus hystrix and Lepidodermella squamata, as well as rarer species, e. g. Haltidytes crassus, Ichthydium diacanthum and Stylochaeta scirtetica, are reported. In Paper II molecular data is used to infer phylogenetic relationships within the morphologically very diverse marine family Thaumastodermatidae (Macrodasyida). Results give high support for monophyly of Thaumastodermatidae and also the subfamilies Diplodasyinae and Thaumastoder- matinae. In Paper III the hypothesis of cryptic speciation is tested in widely distributed freshwater gastrotrichs. Heterolepidoderma ocellatum f. sphagnophilum is raised to species under the name H. -

By the jejuensis n. sp. belonging to the family Thaumastodermatidae, detailed scanning electronic microscopy, we confirmed that is described on the basis of the specimens from subtidal this species is characteristic in having the numerous sand bottom at about 6-7 m depth of Jeju Island, South cuticular gland openings mostly flanking a bristle on the Korea. Ptychostomella jejuensis n. sp. is distinguished from its congeneric species with smooth cuticular armature by the dorsal and dorsolateral surfaces. As the character is consistent character combination: (1) small body up to about 160 µm in throughout the specimens examined, and the species shows length; (2) presence of knob-like cephalic tentacles; (3) the clear discrepancy with the related congeners in the absence of dorsal and ventral adhesive tubes; (4) bifid combination of several macro-characters, we determine it a pedicles; (5) pyriform copulatory organ.

Tardigrade Phylogenetic Systematics at the Family Level Using Morphological and Molecular Data
TARDIGRADE PHYLOGENETIC SYSTEMATICS AT THE FAMILY LEVEL USING MORPHOLOGICAL AND MOLECULAR DATA TARDIGRADE PHYLOGENETIC SYSTEMATICS AT THE FAMILY LEVEL USING MORPHOLOGICAL AND MOLECULAR DATA By CARMEN M. CHEUNG, Hons. BSc. A Thesis Submitted to the School of Graduate Studies in Partial Fulfilment of the Requirements for the Degree Master of Science McMaster University © Copyright by Carmen M. Cheung, September 2012 MASTER OF SCIENCE (2012) McMaster University (Biology) Hamilton, Ontario TITLE: TARDIGRADE PHYLOGENETIC SYSTEMATICS AT THE FAMILY LEVEL USING MORPHOLOGICAL AND MOLECULAR DATA AUTHOR: Carmen M. Cheung, Hons. B.Sc. (McMaster University) SUPERVISOR: Dr. Jonathon R. Stone NUMBER OF PAGES: ix, 137 ii ABSTRACT Tardigrade phylogenetic systematic analyses have been conducted using morphological and molecular data; however, incongruencies between results obtained independently with the data types have been found. This thesis contains new morphological and molecular phylogenetic systematic analyses of tardigrades at the family level, building on previous research. The first part involves morphological data, the second part involves molecular data, and the third part involves combined morphological and molecular data. The morphological data include 50 characters for 15 tardigrade families. The molecular data include updated 18S rRNA, 28S rRNA, and COI gene sequences, in two sets; the first set provides the most-extensive representation of tardigrade families and comprises 18S rRNA sequences; the second set provides the most-complete representation of molecular data per species, where available, and involves the concatenation of 18S rRNA, 28S rRNA, and COI gene sequences. Finally, the combined data involves a supermatrix containing morphological and molecular data. The analyses are used to test results from previous systematics research and to contribute more information to tardigrade systematics. -

ZooKeys 190: 81–94. doi: 10.3897/ zookeys.190.2975 Abstract A new species of Acanthodasys (Gastrotricha, Macrodasyida, Thaumastodermatidae) is described from sublittoral sediments off the Atlantic coast of Florida. Acanthodasys paurocactus sp. n. is a relatively small species (to 450 µm long) with a strap-shaped outline, a series of anterior, lateral, and ventrolateral ad- hesive tubes, paired caudal pedicles with posterior adhesive tubes, and a morphologically diverse cuticle. The cuticle contains both spined and unspined scales. Unspined scales are present in two general shapes: lanceolate and eye shaped, with some transitional shapes. All scales have a thickened rim and depressed central region; some scales of both shapes bear either one or more central bumps, a parallel ridge, or a perpendicular ridge that gives the appearance of a cross-shaped pattern under transmitted light. -
Crasiella Clauseni, a New Gastrotrich Species (Macrodasyida, Planodasyidae) from Jeju Island, South Korea
Anim. Syst. Evol. Divers. Vol. 28, No. 1: 42-47, January 2012 http://dx.doi.org/10.5635/ASED.2012.28.1.042 Crasiella clauseni, a New Gastrotrich Species (Macrodasyida, Planodasyidae) from Jeju Island, South Korea Jimin Lee, Cheon Young Chang* Department of Biological Science, College of Natural Sciences, Daegu University, Gyeongsan 712-714, Korea ABSTRACT A new gastrotrich species of the genus Crasiella (Planodasyidae) is described from the sublittoral sandy bottom of Jeju Island, South Korea. The family Planodasyidae and the genus Crasiella are recorded for the first time from East Asia. Crasiella clauseni n. sp. differs from its congeneric species by the combination of characters: absence of cephalic sensory pits; unseparated arrangement of anterior tubes and ventrolateral tubes, comprising about 120 adhesive tubes along whole body length; 5-7 horizontal rows of adhesive tubes and a pair of TbV in the anterior part of pharyngeal region; bifid pedicles with 8-11 posterior adhesive tubes; and tube-shaped seminal receptacle and copulatory organ. This paper deals with description of the new species, and provides a key to the species of genus Crasiella. Keywords: taxonomy, Gastrotricha, description, key, East Asia INTRODUCTION MATERIALS AND METHODS Marine gastrotrich fauna of East Asia is still poor, in spite Gastrotrichs were collected from the shell-sandy bottom at of serial taxonomic studies accomplished during the past 10 about 6-7 m in depth around Saeseom islet, which is located years and earlier. Twenty eight species of 11 genera have 150 m off Seogwipo Harbor at the southern coast of Jeju Is- been recorded in five families: Cephalodasyidae, Lepidoda- land, South Korea.
