Description of four new species of the Cirolana ‘parva group’ (Crustacea: Isopoda: Cirolanidae) from Thailand,with supporting molecular (COI) data

Four new species of the Cirolana ‘parva group’ from shallow coastal habitats in Thailand are described: Cirolana andamanensis sp. nov. and C. phangnga sp. nov., from the Andaman Sea, and C. siamensis sp. nov. and C. thailandica sp. nov. from the Gulf of Thailand. Molecular (The cytochrome oxidase subunit I gene) analysis incorporating taxa from the Cirolana ‘tuberculate group’ shows a monophyletic clade (Bayesian inference = 1 and maximum likelihood = 100%) within the Cirolana ‘parva group’ with two clades reflecting morphological characters. Cirolana andamanensis sp. nov. with antennula peduncle articles 1 and 2 entirely fused; male pereopod 1 without a setal fringe; uropod peduncle ventrolateral margin with 1 sensory seta. Cirolana phangnga sp. nov., C. siamensis sp. nov. and C. thailandica sp. nov. share the morphological characters of antennula peduncle articles 1 and 2 distinctly articulated; pereopod 1 in male with a setal fringe on the carpus and propodus; uropod peduncle ventrolateral margin with 3 sensory setae. Uncorrected p-distances strongly support the separation of these species, originally based on morphology, and show that the highest value of 32.1% is between C. thailandica sp. nov. and C. andamanensis sp. nov., while the lowest value of 22.5% is between C. phangnga sp. nov. and C. siamensis sp. nov.     

Chilarboreus gen. nov., a new genus of Chilean Scirtidae (Coleoptera: Scirtoidea), with descriptions of three new species

The genus Chilarboreus gen. nov. is described from Nothofagus forests of Chile to accommodate three new species: Chilarboreus fossulatus sp. nov., Chilarboreus acuticollis sp. nov. and Chilarboreus darwini sp. nov. The genus is subdivided into two subgenera: Chilarboreus subgen. nov. (type species: C. fossulatus) and Pictarboreus subgen. nov. (type species: C. darwini). Identification keys to the genera of Chilean Scirtidae and the species in the genus Chilarboreus are provided. The state of knowledge of Chilean Scirtidae is summarized. The position of Chilarboreus within Scirtidae and the phenomenon of wing reduction in Scirtidae are discussed.     

New troglobitic species of the genus Troglocheles (Acari: Prostigmata: Rhagidiidae) from caves in northern Italy and Austria,with a key to adult species of the genus

Three new troglobitic species of rhagidiid mites of the genus Troglocheles – two from northern Italy, Troglocheles quinquesolenidiata sp. nov. and T. lanai sp. nov., and T. christiani sp. nov. from Austria – are described. A key to adults of the known species of the genus Troglocheles Zacharda of the world is given. In these vicariant species the different apomorphic morphological traits, troglomorphisms, are discussed in aspects of allopatric speciation, climatic relict hypothesis and evolutionary processes of adaptation to specific niches and time of occupation of the subterranean habitat. All new taxa are authored by M. Zacharda only.     

Four new species of terrestrial earthworms belonging to the genus Amynthas (Megascolecidae: Oligochaeta) from Taiwan with discussion on speculative synonyms and species delimitation in oligochaete taxonomy

This paper describes four new species of earthworms, Amynthas shinanmontis sp. nov., Amynthas chilanensis sp. nov., Amynthas bilineatus sp. nov., and Amynthas cruxus sp. nov. from Taiwan. Amynthas shinanmontis is sexthecate and parthenogenetic with individuals with various levels of degeneration of spermathecae and male reproductive organs. It occurs at elevations of 1700–2700 m in the Central Mountain Range in southern Taiwan. Amynthas bilineatus and A. chilanensis are athecate and also parthenogenetic. They occur, respectively, at elevations of 1000 m in the central region and 1325 m in the northeastern region of Taiwan. Amynthas cruxus is octothecate, amphimictic, and occurs at elevations of 900–1700 m in southern Taiwan. This paper also discusses confusion and dilemma caused by uncertain, speculative synonyms and parthenogenetic morphs in species delimitation in oligochaete taxonomy, and recommends the use of absolute synonyms and phylogenetic species concept.     

Revision of the Australian endemic genus Hyptiogaster Kieffer (Hymenoptera: Gasteruptiidae), with descriptions of seven new species

The Australian hyptiogastrine wasp genus Hyptiogaster Kieffer is revised. Among other characters, species of Hyptiogaster can be readily distinguished from other Hyptiogastrinae by having an exserted ovipositor and the anterior face of the mesothorax truncate in lateral view. Ten species are recognised including seven which are newly described: H. arenicola Turner, H. humeralis (Schletterer), H. rufus (Westwood), H. cobarensis sp. nov., H. hulli sp. nov., H. kalbarrii sp. nov., H. kiefferi sp. nov., H. naumanni sp. nov., H. pinjarregaensis sp. nov., H. weowaniensis sp. nov. Two synonymies are proposed; H. flavosignata (Kieffer) with H. humeralis and H. crassiceps (Schletterer) with H. rufus. An illustrated key to species is presented and relationships among genera of Hyptiogastrinae and species of Hyptiogaster are discussed.     

Four new species of Mesomyzostoma (Myzostomida: Annelida)

Mesomyzostoma Remscheid, 1918 currently includes three described species that live in the coelom and/or gonads of comatulid crinoids: Mesomyzostoma reichenspergeri Remscheid, 1918, Mesomyzostoma katoi Okada, 1933 and Mesomyzostoma lanterbecqae Summers and Rouse, 2014 in Summers, Al-Hakim et al. 2014. Here we describe four new species of Mesomyzostoma and assess their phylogenetic relationships using 18S rRNA, cytochrome oxidase subunit I and 16S rRNA sequence data. We also designate a neotype for M. katoi as the original types appear to be lost. We record M. reichenspergeri from the Australian Great Barrier Reef and from northern Papua New Guinea, but samples from the type locality (Aru Islands, Indonesia) and previously recorded host are needed for confirmation. The new species of Mesomyzostoma are one Japanese species: Mesomyzostoma okadai sp. nov., and three Australian species: Mesomyzostoma lobus sp. nov., Mesomyzostoma leukos sp. nov. and Mesomyzostoma botulus sp. nov. The first infects the coelom of crinoid arms and pinnules, and the other three are found in crinoid oral discs. We also record M. leukos sp. nov. and M. botulus sp. nov. from Papua New Guinea. Phylogenetic analyses suggest that M. okadai sp. nov. is the sister group to all other Mesomyzostoma.     

A new genus and three new species of free‐living marine nematodes from the Yellow Sea,China

One new genus, Paramphimonhystrella gen. nov., and three new species of free‐living marine nematodes in this genus, P. elegans sp. nov., P. minor sp. nov., and P. sinica sp. nov., are described and illustrated from the Yellow Sea, China. Paramphimonhystrella gen. nov. differs from the similar genus Amphimonhystrella by the elongated buccal cavity, cervical setae and large caudal glands. Paramphimonhystrella elegans sp. nov. is characterized by ovoid amphids and spicules with a small hook at distal end and cylindrical part of tail shorter than conical part. Paramphimonhystrella sinica sp. nov. is characterized by circular amphids, wide buccal cavity, spicules with blunt tip, and cylindrical part of tail longer than conical part. Paramphimonhystrella minor sp. nov. differs from the other two species by its smaller body (shorter than 800 µm), circular amphids, and spicules with sharp tip. The type species of this new genus is P. elegans gen. nov. and sp. nov. Types are deposited in the College of Marine Life Sciences, Ocean University of China.

Annelids (Polychaeta and Oligochaeta) from the Sea of Marmara,with descriptions of five new species

This paper deals with annelids (Oligochaeta and Polychaeta) collected in the Sea of Marmara between 2006 and 2010 at depths from 0 to 66 m. A total of five oligochaete and 198 polychaete species were found. Five polychaete species, namely Prosphaerosyllis marmarae sp. nov., Levinsenia demiri sp. nov., Levinsenia kosswigi sp. nov., Levinsenia marmarensis sp. nov. and Levinsenia tribranchiata sp. nov. are new to science, and five oligochaete and 84 polychaete species are new to the fauna of the Sea of Marmara. A list of species found in the region and their maximum densities are presented at depth intervals. The present material includes six alien polychaete species, Paraprionospio coora, Polydora cornuta, Prionospio (Minuspio) pulchra, Pseudopolydora paucibranchiata, Chaetozone corona and Metasychis gotoi, of which the latter four species were new records for the region.     

Two new species of Niphargus (Crustacea: Amphipoda) from Iran

Two Niphargus species, Niphargus khayyami sp. nov. and Niphargus khwarizmi sp. nov., are morphologically analysed and described. Both species are found in western Iran, which represents the easternmost border of the distributional area for this subterranean amphipod genus. We were unable to attribute N. khayyami sp. nov. to any of 80 Niphargus species that were analysed for 28S ribosomal DNA sequences; sequencing of N. khwarizmi sp. nov. failed. Niphargid findings from west Asia recorded in 5 years imply that almost one half of the range of this large freshwater amphipod genus is still unexplored. http://www.zoobank.org/urn:lsid:zoobank.org:pub:9E9E7CC9-83E2-419F-A394-57197305E1EF
