AbstractA new species of parasitic nematode, Hysterothylacium spirale sp. nov. (Ascaridoidea, Anisakidae), is described based on specimens collected from the intestine and pyloric caeca of the silvery john dory Zenopsis conchifer (Lowe) (Zeiformes, Zeidae), from the Argentinean Shelf (35°05′–40°46′S, 53°03′–58°07′W). Among the 66 valid species described so far in the genus, the new species most closely resembles H. zenis (Baylis, 1929). Both species, apparently specific for fishes of the family Zeidae, share the shape of the dorsal lip, the long expanded lateral alae originating from subventral interlabia and the ornamentation of the tail tip, as well as general morphometry. The combination of these shared features distinguishes both species from all congeners so far known. However, the new species is distinguishable from H. zenis by having shorter interlabia, and consequently the lateral alae originating more posteriorly, shorter spicules, a smaller number of postcloacal papillae and the presence of two pairs of double postcloacal papillae.

A New Species

Three new species of copepod crustaceans are described from material collected from anchialine and brackish habitats inand around the village of Walengkabola on the coast of Muna Island, to the southeast of Sulawesi. A new species of cy-clopoid, Paracyclopina sacklerae n. sp., was described from material collected from the tidal inflow entering into the bot-tom of sinkholes a few metres inland from the shoreline. Detailed comparisons are made with Paracyclopina orientalis(Lindberg, 1941), n. comb., a closely related congener here transferred from its original genus Cyclopetta Sars, 1913. Theassignment of Paracyclopina Smirnov, 1935 to the family Cyclopettidae is followed here despite uncertainty over the va-lidity of some of the families created by the break up of the former Cyclopinidae. Two new species of Boholina Fosshagen& Iliffe, 1989 are described, based on material from the same sinkholes and from caves located up to 700m inland fromthe coast and exhibiting further reduced salinity down to 1.8 ppt. One species, B. parapurgata n. sp., is very closely relatedto B. purgata Fosshagen & Iliffe, 1989 from Bohol island in the Philippines, the other B. munaensis n. sp., is very closelyrelated to B. crassicephala Fosshagen & Iliffe, 1989 also from Bohol island, but a number of fine scale differences in the leg 5 of both sexes are recognised in each case. Keys to valid species of both genera are provided.

A New Species

A new species of Gastrophanella, G. cavernicola sp. nov. (Demospongiae: Siphonidiidae), is described from submarine caves in Fernando de Noronha Island (north-east Brazil), Carrie Bow Cay and Columbus Cay, Belize (central Western Atlantic), at depths of 5-30 m. It differs from all other species of the genus by its lobate shape with thin superficial canals and centrotylote tylostrongyles. Gastrophanella cavernicola sp. nov. is the second record of the genus Gastrophanella from both Brazil and the Caribbean. It is the sixth ‘lithistid’ sponge reported from the Brazilian coast, whereas at least 32 other desma-bearing sponges are known from the Caribbean. The genus now includes five valid species, G. implexa Schmidt from the West Indies (type species), G. mammilliformis Burton from South Africa, G. primore Gómez from the Pacific Coast of Mexico, G. stylifera Mothes & Silva from south Brazil, and G. cavernicola sp. nov. from north-east Brazil and Belize. Aciculites oxytylota Lévi & Lévi from New Caledonia is transferred to Siphonidium Schmidt. The family Siphonidiidae Lendenfeld, which is probably related to order Hadromerida, is redefined to contain only Siphonidium and Gastrophanella, both with fused rhizoclone desmas associated to microspined exotyles.

A new species of caridean shrimp of the family Alpheidae, Automate isabelae sp. nov., found in stomach analysis contents of the lane snapper Lutjanus synagris (Linnaeus, 1758), from the Keys and SW coast of Florida, Gulf of Mexico, is described. The abdomen and portions of the cephalic appendages were damaged in holotype, but remainder of the body and the chelipeds, whith the most important diagnostic characters are in decent or perfect condition, the description was further supplemented based on intact morphological parts of the paratypes. The presence of tubercles on the dorsal and ventral margins of the major chela palm, shows this new species to be related to the eastern Pacific Automate rugosa Coutière, 1902. Both congeners can be easily discriminated by the proportions and shape of the third maxilliped, the proportions and ornamentation of the carpus, merus, and chela of the major cheliped, the ventral seta of the carpus of the minor cheliped, the presence of a distoventral spine on the propodi of third and fourth pereopods, the armature of dorsal surface of telson, and their geographical distribution. The description of this new species increases the number of worldwide valid species known of the genus Automate to 12.

AbstractA new anisakid nematode, Hysterothylacium liparis sp. nov., is described from the intestine and stomach of the fish, Liparis tanakae (Gilbert et Burke, 1912) (Scorpaeniformes, Liparidae), a fish endemic to the Yellow Sea, China. The new species can be distinguished from the congeners by the absence of lateral alae, the length of the intestinal caecum (1.94–3.35 mm, 58.84–82.47% of oesophageal length), the number and arrangement of the caudal papillae (20–29 precloacal subventral pairs, 1 adcloacal pair and 4 postcloacal pairs), the size of the spicules (1.94–3.74 mm, 4.85–7.30% of body length) and the morphology of the tail tip. This is the first species of adult ascaridoid nematodes to be reported from fishes of the family Liparidae in northern China.

A New Species

The family Asterocheridae Giesbrecht has several genera associated with sponges including Asterocheres Boeck, 1859. The type genus is commonly found in sponges but it is also recorded in echinoderms, bryozoans, and corals. A revision of the diagnosis of Asterocheres conducted in 2010 was the beginning of a reorganization process, culminating in the present status of 63 valid species. This study describes a new species and genus of the Asterocheridae. Neoasterocheres gen. nov. shares many characteristics with Asterocheres sensu stricto, except for the antennule segmentation which shows ancestral segments IX–XII fused to segment XIII. The new species of Neoasterocheres gen. nov. was found in association with the sponge Callyspongia sp. sampled at the Yatch Club Bay, located in Todos-os-Santos Bay, Salvador city, Bahia State, Brazil. A revision of the Asterocheres sensu stricto indicates that A. enewetakensis Humes, 1997, A. dysideae Humes, 1996b, A. humesi Varela, 2012, A. rotundus Malt, 1991, A. scutatus Stock, 1966, and A. serrulatus (Humes, 1996a) share this fusion and therefore should be transferred to the new genus. A redescription of Neoasterocheres serrulatus n. comb. is also provided, based on the examination of type specimens.

Three new species of Filiponema, Filiponema sp., and a new species of Iponema are described from earthworms. Filiponema champa sp. n., from the coelomic cavity of Pheretima sp. from Vietnam, is closest to F. cylindropharyngatum and F. javanicum but differs in having a wider body, longer spicules and more conspicuous excretory pore. Filiponema yaoense sp. n., from the coelomic cavity of Pheretima sp. from Vietnam, is differentiated from all valid species of Filiponema by its long, conspicuous excretory duct and a nerve ring situated more closely to the anterior extremity. It can be differentiated from F. champa sp. n. by a slimmer body, the more anterior position of amphids, circular vs transversely elliptical amphids and caudal organs, the wider tail tip, a shorter mail tail, longer eggs, smaller, straighter, spicules and a smaller gubernaculum. Filiponema suifunense sp. n., from the coelomic cavity of Drawida ghilarovi from Russia, is distinguished from all known species of the genus due to the presence of narrow, projecting lateral fields. Filiponema sp., from the coelomic cavity of Lumbricus friendi from France, is described but not named due to lack of material. Iponema visayanum sp. n., from the coelomic cavity of Megascolecidae gen. sp. from the Philippines, can be distinguished from I. tonkinense by its longer spicules and pharynx and its larger amphids situated further from the anterior extremity than in I. tonkinense. D2-D3 LSU sequences were obtained for I. visayanum sp. n. and F. suifunense sp. n. and compared with homologous sequences of other Drilonematoidea nematodes.

A New Species

The family Thorectidae includes 23 valid genera and 130 species, characterized by the presence of laminated fibres and diplodal choanocytye chambers. Currently the genus Thorecta comprises approximately 20 valid species, distributed mainly in the Indo-Pacific. We describe here a new species of Thorecta that is the only valid species of the genus described in the Atlantic Ocean so far. Samples were collected by trawling on board of the RV ‘Astro Garoupa’ in Potiguar Basin, on the northern coast of Rio Grande do Norte State, north-eastern Brazil. Thorecta atlantica sp. nov. is greyish-brown to dark brownish-grey and presents a distinctive globular or clavulate shape, with 1–2 large apical oscules that open to deep atria. It was found between 61 and 160 m depth. A literature survey suggests that many species referred to Thorecta should be relocated to different genera due to absence of diagnostic characters, and that the genus Thorecta should group only 11 species: T. carteri, T. marginalis, T. prima, T. lata, T. farlovi, T. meandrina, T. polygona, T. reticulata, T. tuberculata, T. vasiformis and T. atlantica sp. nov. The tortuous history of the genus is an example of the damage that poorly-described species can cause to classification. Detailed descriptions of fresh material, well illustrated by photographs and including as many characters as possible, are essential tools for the clarification of the systematics of Thorecta in the future.

Abstract During a parasitological survey of fishes at Iguazu National Park, Argentina, specimens belonging to the allocreadiid genus Auriculostoma were collected from the intestine of Characidium heirmostigmata. The erection of the new species is based on a unique combination of morphological traits as well as on phylogenetic analysis. Auriculostoma guacurarii n. sp. resembles four congeneric species – Auriculostoma diagonale, Auriculostoma platense, Auriculostoma tica and Auriculostoma totonacapanensis – in having smooth and oblique testes, but can be distinguished by a combination of several morphological features, hosts association and geographic distribution. Morphologically, the new species can be distinguished from both A. diagonale and A. platense by the egg size (bigger in the first and smaller in the last); from A. tica by a shorter body length, the genital pore position and the extension of the caeca; and from A. totonacapanensis by the size of the oral and ventral sucker and the post-testicular space. Additionally, one specimen of Auriculostoma cf. stenopteri from the characid Charax stenopterus (Characiformes) from La Plata River, Argentina, was sampled and the partial 28S rRNA gene was sequenced. The phylogenetic analysis revealed that A. guacurarii n. sp. clustered with A. tica and these two as sister taxa to A. cf. stenopteri. The new species described herein is the tenth species in the genus and the first one parasitizing a member of the family Crenuchidae.
