Parashiinoa mackayi gen. nov., sp. nov. (Poecilostomatoida: Shiinoidae), a new parasitic copepod from two Australian species of Pomadasys (Haemulidae)

A new genus, Parashiinoa, is proposed for a new species of parasitic copeepod found attached at the base of the dorsal fins of two species of Australian haemulid fishes, Pomadasys maculatus (Bloch) and P. argenteus (Forsskål). The new species, P. mackayi, is described and illustrated. One species of the genus Shiinoa, S. bakeri Cressey and Cressey, is transferred to the new genus. A redefinition of the family Shiinoidae is provided.     

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.     

The life‐cycle of Hemigalichus chrotogale sp. nov. (Acari: Listrophoridae), with comparative observations on listrophorid morphology

A new fur‐mite species, Hemigalichus chrotogale (Acari: Listrophoridae), is described from Chrotogale owstoni (Carnivora: Viverridae) from Vietnam. The external morphology of all instars is described in detail. The precopulatory mate‐guarding behaviour exhibited by H. chrotogale is the first report of this phenomenon in the Listrophoridae. A morphological comparison of all currently recognized listrophorid genera and some early derivative representatives of the family Atopomelidae, which are closely allied to the Listrophoridae, is conducted. The results obtained support the monophyly of Listrophoridae. The family Listrophoridae includes two subfamilies, Listrophorinae, with more than 150 species in 20 genera, and the monobasic Aplodontochirinae, and is characterized by the following synapomorphies: the palps are enveloped by distinct membranes, the prescapular shield covers the gnathosoma, or most of it, dorsally, the clasping organs of coxal fields I are larger than those of coxal fields II, and setae scx, baI–II, pRII, and sIII are absent.     

Paratimmus provulvatus gen. nov., sp. nov. (Dorylaimida: Mydonomidae) from natural forests in Arunachal Pradesh,India

A new genus of soil-inhabiting nematode belonging to the family Mydonomidae Thorne, 1964 Thorne, G. 1964. Nematodes of Puerto Rico: Belondiroidea, new superfamily, Leptonchidae Thorne, 1934 and Belonenchidae new family (Nematoda, Adenophorea, Dorylaimida). University Puerto Rico Agriculture Experiment Station Technical paper No. 39, : 51 [Google Scholar] is described and illustrated from natural forests of Arunachal Pradesh, India. Paratimmus provulvatus gen. nov., sp .nov. is characterized by having a continuous lip region; tiny, asymmetrical odontostyle; single distinctly sclerotized guiding ring; simple, rod-like odontophore; a thin sheath (not spiral) around basal pharyngeal bulb; elongate conoid cardia; mono-opisthodelphic female genital system; transverse vulva; long filiform tail in both sexes and males with dorylaimoid spicules and three to four spaced ventromedian supplements.     

A new deep-water calanoid copepod and the phylogeny of the genus Nullosetigera nom. nov. in the Nullosetigeridae nom. nov. (pro Phyllopus: Phyllopodidae) from Japanese waters

Nullosetigeridae nom. nov. is proposed for Phyllopodidae Brodsky, 1950, nom. nud., and Nullosetigera nom. nov. is introduced for Phyllopus Brady, 1883, non Rafinesque, 1815. A new species, Nullosetigera auctiseta, is described from Japanese waters. Nullosetigera mutica comb. nov. (Sars, 1907) and N. mutata comb. nov. (Tanaka, 1964) are redescribed. Phylogenetic analysis implies that two groups, N. auctiseta–N. mutica group and N. mutata–N. impar–N. bidentata–N. helgae group, exist within the genus Nullosetigera and that the new species first diverges with N. mutica. The relatively advanced species, N. impar, N. bidentata, and N. helgae are the most widespread, and are vertically distributed from the epipelagic to the bathypelagic layers.     

Zenkevitchiidae fam. nov. (Crustacea: Gammaroidea), with description of new subterranean amphipods from extremely deep cave habitats

Previous phylogenetic analysis based on combined mitochondrial and nuclear gene sequences detected paraphyly of the Typhlogammaridae. To test this hypothesis a portion of large subunit (LSU-rDNA) gene sequences were obtained for typhlogammarid species from Caucasus. The Bayesian approach to LSU-rDNA sequences provided evidence for an independent origin of the Dinaric and Caucasus ‘typhlogammarid’ clades. A new family, Zenkevitchiidae fam. nov., is proposed to reconcile the observed phylogeny with the concept of monophyly. Using light microscopy, two mouthpart morphotypes of the Zenkevitchiidae fam. nov. species with quite different setae are identified. Taking into account these two morphotypes, a new classification is proposed – Adaugammarus revazi comb. nov., and Adaugammarus sandroruffoi comb. nov. Additionally, two new stygobiont zenkevitchiid amphipod species – Adaugammarus kasiani sp. nov. and Kruberia relicta sp. nov. – are described from Krubera Cave in Abkhazia. A distribution map and an identification key for the Zenkevitchiidae fam. nov. species of Transcaucasia are provided.

Primno evansi sp. nov. (Amphipoda: Hyperiidea) from the eastern North Atlantic

A new species of hyperiid amphipod, Primno evansi, is described from samples collected on R.R.S. Discovery Cruise 140, August to September 1983, in the eastern North Atlantic. The genus Primno, which has a wide geographic distribution, is now represented by five species with two of these occurring in the eastern North Atlantic. Primno evansi is closest to P. brevidens.     

Some helminths of the volcano rabbit Romerolagus diazi,including a description of the nematode Teporingonema cerropeladoensis gen. nov., sp. nov. (Trichostrongylidae: Libyostrongylinae)

Some helminths are recorded from volcano rabbits Romerolagus diazi, originally captured in Mexico, which died at the Jersey Wildlife Preservation Trust. Teporingonema cerropeladoensis, a new genus and species of trichostrongylid nematode, is described and its position within the Libyostrongylinae discussed.     

Terrapotamon gen. nov., a new genus of freshwater crabs from Malaysia and Thailand,with description of a new species,Terrapotamon aipooae sp. nov. (Crustacea: Decapoda: Brachyura: Potamidae)

A new genus, Terrapotamon gen. nov., is established to accomodate two species of freshwater crabs, Potamon abbotti Rathbun, 1898 from southern Thailand, and a new species, Terrapotamon aipooae sp. nov. from West Malaysia. Members of this genus are characterized by their inflated carapaces, very acutely triangular external orbital angles, and structure of their first male gonopods.     

Redescription of Retilaskeya horrida (di Monterosato, 1874) comb. nov. and a re-evaluation of the taxonomic affinity of the genus Retilaskeya (Caenogastropoda: Triphoroidea)

The family Cerithiopsidae H. Adams and A. Adams, 1853 is distributed worldwide, and comprises around 800 extant species divided into ~40 genera. The most speciose genus within the family is Cerithiopsis Forbes and Hanley, 1850, a taxon currently used as a general receptacle rather than as a proper phylogenetic lineage. We hereby redescribe the rare species Cerithiopsis horrida di Monterosato, 1874, review its nomenclature, known material, and distribution as well as figure the entire protoconch, operculum, and radula for the first time. Our results highlight extreme differences between ‘Cerithiopsis’ horrida and the Cerithiopsis type species Cerithiopsis tubercularis (Montagu, 1803) and strong morphological and radular similarities with species belonging to the genus Retilaskeya Marshall, 1978. A wide discussion lists several taxa that might be ascribed to the same group of species, which presumably constitute a different worldwide lineage. Pending relevant molecular phylogenetic studies of the Triphoroidea Gray, 1847, for morphological conformity we suggest transferring ‘Cerithiopsis’ horrida to the genus Retilaskeya, and the same action is presumably appropriate for its possible sister species ‘Cerithiopsis’ leopardus Rolán and Gori, 2013. Finally, Retilaskeya better conforms to Newtoniellidae Korobkov, 1955 than Cerithiopsidae.     

Brevimulticaecum scleropagi sp. nov. (Ascarididae: Nematoda) from the fish Scleropages jardini in Papua New Guinea

Summary

Examination of ascaridoid nematodes from the osteoglossid fish Scleropages jardini in Papua New Guinea revealed that they belong to a new species and named Brevimulticaecum scleropagi nov. sp. Multicaecum heterotis Petter, Vassiliades and Marchand, 1979 from the African osteoglossid fish Heterotes niloticus was moved to the genus Brevimulticaecum in new combination and reported from the same host in Nigeria and Sudan for the first time. The new species is near to B. heterotis but differs from it in having lips that are not lobed, in the absence of the cervical alae, the much smaller size and measurements of the various organs.     

Taxonomy of Palaearctic scythridids: description of Falkovitshella hindukushi sp. nov. and Scythris wadiqeltella sp. nov. (Lepidoptera: Gelechioidea: Scythrididae)

Two new species are here described and illustrated: Falkovitshella hindukushi sp. nov. from north-eastern Afghanistan, and Scythris wadiqeltella sp. nov. from Palestine. Scythris inconspicuella Sinev is newly recorded from China, markedly extending its known range. http://www.zoobank,org/urn:lsid:zoobank.org:pub:2BC5092F-D004-4CB3-85C7-1CAA54AAE536     

Two new nematodes,Pseudelzalia longiseta gen. nov., sp. nov. and Paramonohystera sinica sp. nov. (Monhysterida: Xyalidae), from sediment in the East China Sea

Pseudelzalia longiseta gen. nov, sp. nov. and Paramonohystera sinica sp. nov. from subtidal sediment in the East China Sea are described. Pseudelzalia is characterized by 6 labial papillae and 10 cephalic setae, cylindrical buccal cavity, elongate (>2 anal body diameter) spicules, and conico-cylindrical tail devoid of terminal setae. It differs from Elzalia by the absence of terminal setae. Pseudelzalia longiseta sp. nov. is 647–853 μm long, has 7–8 μm long cervical setae, 11–14 μm long caudal setae, 25–41 μm long spicules about 2.1–2.7 anal diameter, and pointed tail-tip. Paramonohystera sinica possesses 12 cephalic setae, a character found in four congeners: Paramonohystera buetschlii (Bresslau and Schuurmans Stekhoven in Schuurmans Stekhoven, 1935, Paramonohystera pilosa Boucher, 1971, Paramonohystera concinna Lorenzen, 1977 and Paramonohystera halerba Fadeeva and Belogurov, 1987. It differs from P. buetschlii by shorter body (933–1023 μm versus 2000–2200 μm); from P. pilosa by the much shorter spicules (79–88 μm versus 167 μm) and narrower head (13–16 µm versus 32 µm); from P.concinna by smooth cephalic setae (versus segmented); and from P. halerba by the absence of two rows of setae on the ventral side of the tail (versus present). Based on the evaluation of nominal species, we recognize 14 valid species and provide an emended diagnosis and a tabular key for Paramonohystera.

Classical Biological Control of Bemisia tabaci in the United States. By Juli Gould,Kim Hoelmer & John Goolsby

ABSTRACT

The present study describes two new genera, six new species and three new records from the Sea of Marmara. The new genus Marmara gen. nov. belonging to the family Sagartiidae is mainly characterized by having conspicuous muscular belts along the column and the absence of suckers and tenaculi on the body wall. The genus Charisactis gen. nov. belonging to the family Condylanthidae is mainly characterized by having an atypical mesentery arrangement, single siphonoglyph and homotrichs in tentacles. The other species newly described from the Sea of Marmara belong to the families Diadumenidae (one species from deep waters), Halcampoididae (one species from shallow waters), Edwardsiidae (one species from shallow waters) and Epizoanthidae (one species from deep waters). Three species, namely Epizoanthus arenaceus (family Epizoanthidae), Rolandia coralloides (family Clavulariidae) and Virgularia sp. (family Virgulariidae) are reported for the first time from the Sea of Marmara. The external and internal anatomical features as well as cnidom structures of the species are presented and discussed with the closely related species. http://www.zoobank.org/urn:lsid:zoobank.org:pub:51DA9869-D786-4A8A-8C1F-62DC1BB67923     

Two new species of the family Photidae (Amphipoda: Corophiidea: Photoidea) from Brazilian waters,with description of Rocasphotis gen. nov.

A new species, Photis sarae sp. nov., is herein described from Guanabara Bay, Rio de Janeiro. The new species is similar to the Hawaiian species, Photis hawaiensis Barnard, 1955, and an undescribed species, Photis sp. F (LeCroy 2000 LeCroy, S.E. An illustrated identification guide to the nearshore marine and estuarine Gammaridean Amphipoda of Florida. Volume 1. Families Gammaridae, Hadziidae, Isaeidae, Melitidae and Oedicerotidae. Florida Department of Environmental Protection, Tallahassee, Annual Report, Contract No. WM724, 195. 2000.  [Google Scholar]), from Biscayne Bay, Florida. Photis sarae sp. nov. can be distinguished from both species in having gnathopod 2 basis with two long setae on posterior margin, palm with only one spine (excluding palmar corner), pereopod 3 anterior margin of merus with long plumose and simple setae, and dactyli of pereopods 5–7 with accessory spine and telson trapezoidal with distal margin concave. Also, Rocasphotis gen. nov. is described based on material collected from Atol das Rocas, which is closely related to the genus Photis and also corresponds to a new species. Rocasphotis gen. nov. mainly differs from Photis in having antenna 1 shorter than antenna 2, peduncular article 1 longer than article 3, accessory flagellum absent, coxae 1–4 with sparse slender setae; lateral cephalic lobe weakly extended and acute distally; eyes large, poorly developed, composed of sparse ommatidia, and partly enclosed in the lobe. A key for all genera of the family Photidae is given.     

A new earthworm genus Nouraguesia gen. nov. from French Guiana with description of two new species (Oligochaeta,Glossoscolecidae)

Nouraguesia gen. nov., consisting of three species, is described from Eastern Amazonia. Species belonging to this genus are middle-sized earthworms inhabiting, based on our experience, decomposing tree logs and space filled with detritus between leaf-axils and trunk (e.g. in some palm species). The new genus is morphologically similar to the genus Andiorrhinus, but differs from it by the presence of numerous caeca encircling the intestine in segment 27. The three species belonging to the newly established genus are known from state Amapa in Brazil (N. amaparis (Righi, 1971)); and French Guiana (N. parare sp. nov., N. souadae sp. nov.).     

Extremalona timmsi gen. nov., sp. nov., a new cladoceran (Cladocera: Anomopoda: Chydoridae) from an acid saline lake in southwest Western Australia

A new species of Cladocera, Extremalona timmsi gen. nov., sp. nov., was found in acid saline lakes in the southwest of Western Australia. Extremalona gen. nov. belongs to the Coronatella-branch of Aloninae, but differs from all members of the group by the oval body with small high-set head (tip of rostrum located at half-height of the body), the exopodite III with uniform, well-developed setae 4–6 and male antennule with six lateral and nine terminal aesthetascs, and by numerous other characters. In our opinion, Extremalona gen. nov. is one of the ancestral genera of the Coronatella-branch of Aloninae, sharing numerous common features with the elegans-group of Alona s.l. Our data confirm a high level of endemism in Australian Chydoridae and Cladocera in general.     

Some helminth parasites of marine fishes of South Africa: Santeria rubalo gen. et sp. nov. (Digenea: Cryptogonimidae)

A new genus and species, Santeria rubalo, is described from the sparid fish Cheimerius nufar from the south-western Indian Ocean. It is placed in the cryptogonimid subfamily Neochasminae and is distinguished from Paracryptogonimus and Apophallus mainly by its oral spination, which consists of six to eight annular rows of spines.
