A new species of Notomastus (Annelida, Capitellidae) from southern China, with remarks on its morphology and distribution.

ABSTRACT: The genus Notomastus is frequently encountered in Chinese waters. However, its species richness is poorly understood. In this study, a Notomastus species obtained from Xiamen Bay, southern China, was described and illustrated as a new species (N. sunae sp. nov.), based on morphological and molecular analyses. The new species is characterized by having uniramous chaetiger 1, the presence of palpode and eyespots on prostomium, chaetiger 11 with notopodial capillaries and neuropodial hooded hooks, and notopodial lobes with simple epithelial extensions on far posterior abdomen. With additional specimens collected from several localities along the southern coasts of China, the morphology and geographical distribution of the new species are discussed. A key is also provided for Notomastus species with neuropodial hooks in thoracic chaetiger 11.

Two new species of Mediomastus (Annelida, Capitellidae) from Tokyo Bay, Japan.

Project description:Two undescribed species of polychaetes in Mediomastus (Annelida: Capitellidae) were collected from intertidal to shallow habitats in Tokyo Bay, Japan. These are M. duobalteus sp. n. and M. hanedaensis sp. n. Mediomastus duobalteus sp. n. is distinguishable from all congeners by the following characters: 1) segments 3, 4, 8-11 stainable with methyl green, 2) thoracic capillary chaetae unilimbate, 3) abdominal capillary chaetae absent, 4) paddle-like chaetae in the thorax absent, and 5) abdominal hooded hooks not flared. Mediomastus hanedaensis sp. n. is similar to M. warrenae Green, 2002, but differs from the latter in the shapes of the thoracic capillary chaetae and the abdominal hooded hooks, and the staining pattern with methyl green. In addition, a key to all Mediomastus species is provided.

A new species of Leiochrides Augener, 1914 (Annelida: Capitellidae) from the Beibu Gulf, South China Sea.

Project description:BackgroundPolychaetes of the family Capitellidae are poorly studied in Chinese waters. Amongst the known capitellid genera in China, Leiochrides Augener, 1914 is an unusual genus encountered in marine surveys.New informationIn this study, a Leiochrides specimen was obtained during a survey conducted in the Beibu Gulf, northern South China Sea and described herein as a new species Leiochrides guangxiensis sp. nov. The new species differs from its congeners by having uniramous chaetiger 1, chaetigers 11-12 with notopodial capillaries and neuropodial hooks, abdominal hooks with seven teeth above the main fang in three rows, pygidium with four anal cirri, and branchial fascicles with up to 17 filaments. The taxonomic status of the monospecific genus Pseudoleiocapitella Harmelin, 1964 and Leiochrides norvegicus Fauchald, 1972 are discussed.

Two species of Naididae (Annelida, Clitellata) from southern Tibet, China.

Project description:One new species of Naidinae (Oligochaeta, Naididae), Naisbadia sp. n. and one new record species from China, Tubifexmontanus Kowalewski, 1919 (Tubificinae) are found in southern Tibet. The new species is distinguished from congeners by its large area of reddish brown pigment in the anterior segments I-VIII, serrate hairs, pectinate needles with 1-2 intermediate teeth, ventral chaetae partly with 1-2 fine intermediate teeth and wave-like movements. The new material of the species Tubifexmontanus differs slightly from the previous descriptions by its vas deferens entering atrium subapically, wide ental end of penial sheath and smooth hair chaetae.

A new Notomastus (Annelida, Capitellidae) species from Korean waters, with genetic comparison based on three gene markers.

Project description:Notomastus koreanussp. n., collected from the sublittoral muddy bottom of Korean waters, is described as a new species. The Korean new species closely resembles N. torquatus Hutchings & Rainer, 1979 in the chaetal arrangement and the details of abdominal segments, but differs in the position of genital pores and the absence of eyes. DNA sequences (mtCOI, 16S rRNA, and histone H3) of the new species were compared with all the available sequences of Notomastus species in the GenBank database. Three genes showed significant genetic differences between the new species and its congeners (COI: 51.2%, 16S: 38.1-47.3%, H3: 3.7-9.3%). This study also includes a comprehensive comparison of the new Korean Notomastus species with its most closely similar species, based on the morphological and genetic results.

Three new species of Heteromastus (Annelida, Capitellidae) from Korean waters, with genetic evidence based on two gene markers.

Project description:Three undescribed species of Heteromastus Eisig, 1887 were collected from intertidal to sublittoral habitats in western and southern waters of Korea. Heteromastus namhaensis sp. nov. is distinguishable from other congeners by the presence of hemispheric notopodial lobes in the posterior abdomen. Heteromastus gusipoensis sp. nov. closely resembles H. tohbaiensis Yabe & Mawatari, 1998 in the absence of posteriorly extended abdominal notopodial lobes, but differs in the absence of eyespots on the prostomium and distinct node on the shaft of thoracic hooks in H. gusipoensis. Heteromastus koreanus sp. nov. is similar to H. filiformis sensu Hutchings & Rainer, 1982 in the shape of abdominal notopodia, but clearly differs in dentition of the abdominal hooks and methylene green staining pattern (MGSP). DNA sequences (mtCOI and histone H3) of these new Korean species were compared with all sequences of Heteromastus species available in the public database. Molecular results showed distinct genetic differences among these three new Korean species at species level. Comparison of mtCOI gene revealed significant genetic difference between H. filiformis and these Korean species. A comprehensive comparison between three Heteromastus species of present study and their closely related congeners is conducted based on morphological and genetic results.

Morphology and molecular genetics reveal two new Leptobrachella species in southern China (Anura, Megophryidae).

Project description:Based on morphological and phylogenetic analyses (16S rRNA mtDNA), two new species of the genus Leptobrachella are described from southern China, namely L.yunkaiensis Wang, Li, Lyu & Wang, sp. n. from Dawuling Forest Station of Guangdong Province and L.wuhuangmontis Wang, Yang & Wang, sp. n. from Mt. Wuhuang of Guangxi Province. To date, the genus Leptobrachella contains 68 species, among which 13 species are known from China. The descriptions of the two new species further emphasize that the species diversity of the genus Leptobrachella from China is still highly underestimated and requires further investigations.

A new species of Leiochrides from the Korean subtidal waters with notes on the taxonomic status of the genus Pseudomastus (Annelida, Capitellidae).

Project description:Leiochrides yokjidoensissp. n., collected from the sublittoral muddy bottom in southern Korea, is described as a new species. The taxonomic status of the monospecific genus Pseudomastus has been a subject of controversy for many years, as its characteristics overlap those given in recent generic definitions of Leiochrides. The results of a comprehensive review and comparison regarding the two genera, based on previous records showed minor differences. In this study, a detailed description of L. yokjidoensissp. n. is given and a comparison with closely related species is tabulated and discussed.The taxonomic status of Pseudomastus is discussed and the genus placed in synonymy with Leiochrides.

A new species and a new species record of Orbiniidae Hartman, 1942 (Annelida, Polychaeta) from China.

Project description:A new species of the orbiniid genus Phylo Kinberg, 1866, P.heterochaetus sp. nov., is described based on material collected from the northern Yellow Sea, China. This is the thirteenth species in Phylo. The new species can be easily identified by the combination of the following characters: anterior thorax with 13 chaetigers, interramal cirri absent, anterior thoracic neuropodia with 4 or 5 rows of uncini, intermixed with a few subuluncini in the first 1 or 2 rows, and a ventral fringe of numerous stomach papillae present on chaetigers 12-24. Phylofimbriata is recorded for the first time from China seas.
