The present paper deals with two new species of oribatid mites of the genus Scapheremaeus Berlese, 1910 from the subtropical islands in Southern Japan. Scapheremaeus nakanoshimensis sp. nov. and Scapheremaeus boninensis sp. nov. are proposed on the basis of adults. Furthermore, we present data on distribution, diversity and habitat ecology of all known species of Scapheremaeus in Japan, and a key is provided for identification of hitherto recorded species in this country. Majority of Scapheremaeus species found in Japan are known to be restricted to areas of Southern Japan and Eastern China. Only one of the species has a relatively broad distribution in South America and East Asia. Most species of Scapheremaeus in Japan are inhabitants of soil and litter of various forests, and mosses growing on rocks, but few of them are arboreal. The D3 fragments of the 28S rRNA (28S D3) and 18S rRNA genes of Scapheremaeus nakanoshimensis sp. nov. are sequenced and data are available in the sequence database. Comparison of the 28S D3 gene sequence of Scapheremaeus nakanoshimensis sp. nov. with other oribatid mites gene sequences identifies that the representatives of Scutoverticidae (Scutovertex, Provertex, Exochocepheus) and Eremaeozetidae (Eremaeozetes), Ameronothridae (Ameronothrus) and Phenopelopidae (Eupelops) are the closest relatives to Scapheremaeus with regard to the species included in this analysis.

Benthic harpacticoids were collected from Korean waters. Two species were identified as members of the genus Longipedia Claus, 1863, because they have an extremely elongated distal segment of the P2 endopod. Longipedia koreana sp. nov. is morphologically most closely related to L. nichollsi Wells, 1980 and L. scotti Sars, 1903, but it can clearly be distinguished from both species based on the following morphological characteristics: P1 coxa with strong spinules near the outer margin and the distal element being much bigger than the proximal elements, P2 coxa with a small inner seta on the anterior surface, P4 exopod first segment without an inner element, and the P5 with a rectangular exopod (more than 3.5 times as long as wide). L. ulleungensis sp. nov. is similar to L. brevispinosa Gurney, 1927, L. spinulosa Itô, 1981, and L. weberi Scott A., 1909. However, L. ulleungensis sp. nov. is characterized by the P2 coxa with a reduced inner seta, the P4 exopod second segment without an inner seta, and the anal operculum with a long median projection, a single spine, and a group of outer spines on each side. In a molecular analysis using the mitochondrial cytochrome c oxidase subunit I (COI) and 18S ribosomal RNA (18S rRNA) genes, the inter-specific variation was 22.525–23.102% and 1.325–1.382% of COI and 18S rRNA between the two new species, respectively. A key to the family Longipediidae is provided herein.

Longidoruschenisp. n., an amphimictic species recovered from the rhizosphere ofLarixprincipis-rupprechtiiandPyracanthafortuneanain Shanxi and Beijing, China, is described and illustrated. The taxonomic position ofL.chenisp. n.among other species within the genus was elucidated using morphometric and molecular data, and phylogenetic relationships were inferred using D2–D3 expansion domains of 28S and 18S rRNA genes by Bayesian Inference (BI) method. The new species is characterised by females with a medium body size (L = 4.9–6.6 mm), a lip region slightly expanded, broadly rounded frontally and laterally, the amphidial fovea broad and symmetrically bilobed at base, odontostyle long and slender (143–168 μm), odonthophore slightly swollen at the base, tail short bluntly conoid to rounded. Guide ring located far posterior from the oral aperture (70–93 μm). Males with two ad-cloacal pairs of supplements preceded by a row of 10–14 ventromedian supplements, with robust spicules measuring 111–126 μm along the median line. Three juvenile stages were present, tail shape of J1 elongate conoid while in J2 and J3 the tail gradually becomes bluntly rounded. Codes for identifying the new species are: A6-B3-C5-D2-E2-F3-G1-H1-I2-J2-K2.Longidoruschenisp. n.belongs to a group of species with a guide ring at the mid-odontostyle position that have a predominantly Asiatic origin. It differs from all of them by a combination of morphological characters and unique sequences of partial 18S and D2–D3 region of 28S rRNA genes. The percentage dissimilarities in partial 18S and D2–D3 28S rRNA genes ofL.chenito the closest species (L.litchii,L.fangi,L.jonesiandL.juglans) were 1.5 %–1.8 % and 16.8–18.3 %, respectively.

A new species of the genusDitylenchus,D.persicusn. sp., was collected around the roots of grapevine and is described and illustrated herein based on morphological and molecular studies. The new species is characterised by a body length of 783 (635-928) μm and 689 (670-715)μm in female and male, respectively, delicate stylet 6.2 (5.0-7.0)μm long, six lines in the lateral field, median bulb of pharynx well developed, muscular with crescentic valve, basal pharyngeal bulb pyriform with 10 (8-13)μm long stem extending into intestine, post-vulval uterine sac relatively short, 16 (14-18)μm long, female and male tail elongate-conoid with finely rounded terminus, and bursa covering 65-80% of male tail length. Morphologically,D.persicusn. sp. appears closer to five known species of the genus, namely:D.arachis,D.caudatus,D.clarus,D.myceliophagusandD. nanus. The results of phylogenetic analyses based on sequences of D2-D3 expansion region of 28S rRNA, ITS and partial 18S rRNA genes confirmed the close molecular relationship betweenD.persicusn. sp. and otherDitylenchusspecies such asD. myceliophagus,D. africanus,D. arachis,D. destructorandD. halictus.

Abstract The aim of the study is to test a hypothesis for the phylogenetic relationships among mammalian hymenolepidid tapeworms, based on partial (D1–D3) nuclear 28S ribosomal RNA (rRNA) genes, by estimating new molecular phylogenies for the group based on partial mitochondrial cytochrome c oxidase I (COI) and nuclear 18S rRNA genes, as well as a combined analysis using all three genes. New sequences of COI and 18S rRNA genes were obtained for Coronacanthus integrus, C. magnihamatus, C. omissus, C. vassilevi, Ditestolepis diaphana, Lineolepis scutigera, Spasskylepis ovaluteri, Staphylocystis tiara, S. furcata, S. uncinata, Vaucherilepis trichophorus and Neoskrjabinolepis sp. The phylogenetic analyses confirmed the major clades identified by Haukisalmi et al. (Zoologica Scripta 39: 631–641, 2010): Ditestolepis clade, Hymenolepis clade, Rodentolepis clade and Arostrilepis clade. While the Ditestolepis clade is associated with soricids, the structure of the other three clades suggests multiple evolutionary events of host switching between shrews and rodents. Two of the present analyses (18S rRNA and COI genes) show that the basal relationships of the four mammalian clades are branching at the same polytomy with several hymenolepidids from birds (both terrestrial and aquatic). This may indicate a rapid radiation of the group, with multiple events of colonizations of mammalian hosts by avian parasites.

Two new species are described: Ramusella paraarcuata sp. nov. differs from Ramusella arcuata Mahunka & Mahunka-Papp, 2012 by the larger body size, lamellar setae similar in length and thickness to interlamellar setae, the presence of two or three branches on bothridial setae, and the absence of notogastral setae c. Neoribates paragracilis sp. nov. differs from Neoribates gracilis Travé, 1972 by the larger body size, and the presence of long apex (not shorter than head) on bothridial setae.

Summary Helicotylenchus ciceri n. sp. and H. scoticus are described and illustrated based on morphological, morphometric and molecular characters. The new species is characterised by a conical and truncated lip region with five or six distinct annuli, stylet 32-37 μm long with anteriorly concave knobs, secretory-excretory pore posterior to the pharyngo-intestinal valve, dorsally convex-conoid tail with a terminal projection, phasmids 14 (7-20) annuli anterior to the level of anus, empty spermatheca and absence of males. Intraspecific variation of 16 populations of H. scoticus, collected from chickpea and lentil fields in Kermanshah province, western Iran, is discussed. The results of the phylogenetic analyses based on the sequences of the partial 18S rRNA, D2-D3 expansion segments of 28S rRNA and ITS rRNA genes are provided for the studied species, confirming their differences from each other and determining the position of them and their relationships with closely related species.
