Report on Crassispirinae Morrison, 1966 (Mollusca: Neogastropoda: Turridae) from the China Seas

The present paper reports 32 turrid species from the China Seas, belonging to eight genera of the subfamily Crassispirinae of the family Turridae. Four new species are described: Funa cretea sp. nov., Inquisitor plurivaricis sp. nov., Inquisitor vividus sp. nov. and Ptychobela resticula sp. nov. Eight species are recorded for the first time from the China Seas.     

The West Palaearctic species of Fidiobia Ashmead, 1894 (Hymenoptera: Platygastroidea)

One new genus Songmachilis and six new species in family Machilidae are described from China: Songmachilis xinxiangensis gen. sp. nov., Coreamachilis songi sp. nov., Pedetontinus jiuzhaiensis sp. nov., Pedetontinus maijiensis sp. nov., Pedetontinus taishanensis sp. nov. and. Pedetontinus wudangensis sp. nov. A key to all Chinese species of Pedetontinus is given. We also examined the relationships among Chinese machilids based on partial sequences of mitochondrial cytochrome c oxidase subunit I (COI). The molecular study further supported the species status of the six new taxa.     

New taxa of the family Trochometridiidae (Acari: Heterostigmata) associated with insects from Iran

A new genus and two new species of mites of the family Trochometridiidae (Acari: Heterostigmata) are described from Iran: Neotrochometridium sensillum Hajiqanbar and Khaustov gen. nov., sp. nov. associated with two carabid beetles and Trochometridium iranicum Hajiqanbar and Khaustov sp. nov. associated with a halictid bee. We also present the first report of two previously described species. These findings provide the first record of the family Trochometridiidae from Iran. The chaetotaxy of tarsus I of the family is discussed and a key to world genera and species is provided.     

A new genus and species of terrestrial isopod from Malaysia (Crustacea,Oniscidea, Platyarthridae)

A new terrestrial isopod, Cephaloniscus sociabilis gen. nov., sp. nov., from Fraser Hill in central Malaysia, is described and illustrated. The new genus belongs to the family Platyarthridae and is distinguished from other members of the family by the characteristic structure of the cephalon. The specimens were collected from the nest of the termite Hospitalitermes sp. (near medioflavus Holmgren) together with the ant Centromyrmex hamulatus (Karavaiev).     

A new genus with three new species of copepods from the family Diaixidae (Crustacea: Calanoida), and a redefinition of the family

Plankton samples taken in the Gulf of Carpentaria, Australia, yielded material of a new genus containing 3 new species: Anawekia spinosa gen. nov. et sp. nov., A. robusta sp. nov. and A. bilobata sp. nov., which are described herein. The family Diaixidae now contains 12 described species in 2 genera, 9 being in the genus Diaixis. It is noted that 3 of the Diaixis species (including the type species) share some features which are not shared with the remaining 6 species, and that these latter species should probably be placed into a third genus. An amplified redefinition of the family is given.     

Two new species of the genus Sinella Brook, 1882 (Collembola: Entomobryidae) from East China

Two new species, Sinella hexaseta sp. nov. and Sinella pauciseta sp. nov., collected from East China, Anhui and Zhejiang provinces, respectively, were described. Both are easily discriminated from each other and all known Sinella species by their unique dorsocentral chaetotaxic patterns on Abd. IV. In S. pauciseta sp. nov., postlabial setae H_1–4 are ciliate, which are smooth in all other known species of the genus.     

Report on the Raphitomidae Bellardi, 1875 (Mollusca: Gastropoda: Conoidea) from the China Seas

Twenty-seven Raphitomidae species belonging to nine genera, are recorded from the China Seas, including two new species, which are described here: Asperdaphne paramoretonica sp. nov., Daphnella inangulata sp. nov. Eight species are recorded for the first time from the China Seas.     

A new genus and two new species of Parastenocarididae (Copepoda: Harpacticoida) from southeastern India

Indocaris gen. nov. with two new species, Indocaris imbricata sp. nov. and Indocaris inopinata sp. nov., and also for the already known Indocaris tirupatiensis (Ranga Reddy 2011a) comb. nov. – all from the groundwaters in peninsular India. The highly diagnostic synapomorphy of the new genus is a composite character associated with the male leg 4 basis: five or six prominent, imbricate, enlarged, petal-like spinules, arranged as a semi-whorl at the insertion of the endopod and increasing in size from internal to external. Another distinctive feature of the same appendage is that its one-segmented endopod is dilated or bulbous in the proximal half, produced distally into an incurved spiniform or horn-like structure about as long as the corresponding first exopodal segment, and ornamented with three or four fine spinules on the subproximal outer margin. The three species also share a unique constellation of other salient morphologic features, which along with the phylogenetic position of Indocaris gen. nov. within the family Parastenocarididae are discussed. Indocaris gen. nov. has closest phylogenetic affinity with the Neotropical Remaneicari Jakobi, 1972. A short note on the ecology and biogeography of the parastenocaridid species of the Indian subcontinent is provided besides a key for their identification.     

A new pontoniine shrimp (Crustacea: Decapoda: Palaemonidae) from the Ryukyu Islands,Japan

An unusual new genus and species of pontoniine shrimp, Nippontonia minirostris gen. nov., sp. nov., from a sponge host from the Ryukyu Is., Japan, is described and illustrated. The new genus appears not to be closely related to any of the previously described genera. The genus is particularly remarkable for the morphology of the fixed finger of the minor second pereiopod, which is without parallel in the Palaemonidae.     

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.     

A new damsel-dragonfly from the Mesozoic of China with a hook-like male anal angle (Odonata: Isophlebioptera: Campterophlebiidae)

A new genus and species of campterophlebiid dragonfly, Angustiphlebia mirabilis gen. nov. et sp. nov., is described from the Jiulongshan Formation in China. It has some remarkable venational structures, i.e. a hypertrophy of the male hind wing anal angle, a quite long gaff, and a secondary branch of the anal anterior near subdiscoidal cell in hind wing, supporting the hypothesis of a sister-group relationship with the genus Oreophlebia. These new data will help to solve the phylogenetic relationships within the Campterophlebiidae. http://www.zoobank.org/urn:lsid:zoobank.org:pub:16E602E6-3567-44D7-BF64-95A6597E55DE     

Pontoniine shrimps from the Zoological Museum,Copenhagen

Three species of Indo-West Pacific pontoniine shrimp from the collection of the Zoological Museum, Copenhagen, have been examined. Two of the species were found to be new, Periclimenaeus mortenseni sp. nov. and P. wolffi sp. nov., from the Kei Islands, Indonesia, and off south west Taiwan, respectively, and are described and illustrated. Remarks, with illustrations, on little known, closely related species, Periclimenaeus pachydentatus Bruce 1969 and P. tridentatus (Miers, 1884), are also included. Platycaris latirostris Holthuis 1952, is recorded from Mauritius for the first time.     

Two new palaemonid shrimps (Crustacea: Decapoda) from the Australian North West Shelf

Two palaemonid shrimps, from about 80 and 50 m on the Australian North West Shelf, are described and illustrated. A new genus, Carinopontonia, is designated for the single incomplete specimen of C. paucipes sp. nov. The new genus is most closely related to the genus Dasycaris Kemp, 1922. A single specimen of a second shrimp can be referred to Apopontonia Bruce, 1977, but to neither of the known species, and it is now described as A. tridentata sp. nov.     

Three new species and one new record of the genus Doryphoribius Pilato, 1969 (Tardigrada: Eutardigrada: Hypsibiidae) from the Great Smoky Mountains National Park (Tennessee,USA)

Box jellyfishes (Cnidaria: Cubozoa) have a profound impact on human activities because of their highly potent venoms that may lead to severe envenomations in humans. Cubozoa is one of the smallest classes within Cnidaria with only some 50 described species in seven families. The literature on Cubozoa is scattered and oftentimes difficult to access. In particular, comprehensive treatments of Cubozoa that present a comparative overview of the group are either non-existent or largely outdated. Here we provide a synopsis of the carybdeid Cubozoa (Carybdeida) including an illustrated key to the families and genera of this order. Of particular interest is the family Carukiidae, which contains the species that was originally attributed with causing a severe envenomation syndrome called Irukandji syndrome. One new species of Carukiidae, Malo filipina sp. nov., is described, Morbakka virulenta is redescribed and a neotype is designated, and an unidentified species of Morbakka is recorded from the Philippines.     

New family and genus Rostrocalanus gen. nov. (Crustacea: Calanoida: Rostrocalanidae fam. nov.) from deep Atlantic waters

Two new species of a new genus and family Rostrocalanidae of benthopelagic clausocalanoid copepods are described from female specimens collected from abyssal depths close to the sea bed in the tropical Atlantic. Rostrocalanus gen. nov. shares the presence of sensory setae on maxilla with other bradfordian families of Clausocalanoidea, but does not fit the diagnosis of any of these families. A family Rostrocalanidae is established for this new genus and is defined by the following derived characters: four‐segmented exopod of mandible supplied with four setae; distal basal endite of maxillule fused to endopod and bearing five setae in total; endopod of maxilla furnished with six worm‐like sensory setae; arrangement of setal numbers on praecoxal endites of maxilliped syncoxa as 0, 1, 2. The establishment of a new clausocalanoidean family sheds new light on the morphological diversity of bradfordian benthopelagic copepods and adds to the biodiversity of the deep‐water calanoid fauna.     

Two new free-living marine nematode species of Xyalidae (Monhysterida) from the Yellow Sea,China

Two new species of free-living marine nematodes Paramonohystera eurycephalus sp. nov. and Steineria sinica sp. nov. from the Yellow Sea, China are described. Paramonohystera eurycephalus sp. nov. is characterized by relatively wide head diameter (33 μm in width), large cup-shaped buccal cavity; presence of numerous long cervical setae; amphidial fovea 18–20 μm in diameter; spicules slender, arcuate, 3.1–3.2 anal body diameter; gubernaculum tubular with a distal hook; five to six minute precloacal supplements. Steineria sinica sp. nov. is characterized by eight groups of three subcephalic setae at almost same level as cephalic setae; eight groups of two long cervical setae situated between subcephalic setae and amphidial fovea; amphidial fovea round, 35% of corresponding body diameter, about one head diameter from anterior end; spicules slender, cephalate proximally and taper distally; gubernaculum pipe-shaped with dorsocaudal apophysis; tail conico-cylindrical with three long terminal setae.     

Some monogenean parasites of marine perciform fishes of Kuwait

Three monogenean parasites are reported from marine perciform fishes kept in culture tanks at Al-Raas, Kuwait. Tareenia acanthopagri gen. et sp. nov. (Capsalidae: Benedeniinae) and Polylabris angifer sp. nov. (Microcotylidae: Prostatomicrocotylinae) are described from skin and gills, respectively, of Acanthopagrus latus (Sparidae). Megalocotyloides epinepheli Bychowsky and Nagibina, 1967 (Capsalidae: Megalocotylinae) is recorded from skin of Epinephelus tauvina (Serranidae). It is also proposed that Benedenia plataxicola Gupta and Khanna, 1975 and Allometabenedeniella plataxi Velasquez, 1982 are synonyms of Benedenia orbicularis Gupta and Khanna, 1975 and that the latter is transferred to the genus Allometabenedeniella Velasquez, 1982 as A. orbicularis comb. nov. Allosprostonia tauvinae Lawler and Hargis, 1968 is considered to be a synonym of Megalocotyloides epinepheli Bychowsky and Nagibina, 1967.     

Two new species of the genus Paracyatholaimus Micoletzky (Nematoda: Cyatholaimidae) from the Yellow Sea

Two new free-living marine nematode species of Paracyatholaimus Micoletzky, 1923 Paracyatholaimus qingdaoensis sp. nov. and Paracyatholaimus huanghaiensis sp. nov. from the Yellow Sea, China are described. Paracyatholaimus qingdaoensis sp. nov. is characterized by cylindrical body with conical tail; spicules reverse S-shaped, distally pointed; gubernaculum plate, with two cusps at distal end, parallel to the spicules; 10 thick setose precloacal supplements in a 5 + 5 arrangement, anterior group of five supplements located at a protuberance. Paracyatholaimus huanghaiensis sp. nov. is characterized by a cylindrical body with conic-cylindrical tail; slender spicules curved, distally pointed; gubernaculum handle-shaped, expanding distally to a plate, with some sawteeth at distal end; three papillose precloacal supplements, each papilla protruding conically with cuticularized narrow ducts. A key for identification of species of Paracyatholaimus is proposed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:0A8E40E5-AE7A-47DA-B755-61E1D088C1E9
