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.     

Redescription of Alona macracantha Smirnov and Timms, 1983 and its assignment to Maraura gen. nov. (Cladocera: Anomopoda: Chydoridae)

Three new species of the harpacticoid family Ameiridae are described from clean sand at high water neap tide on St Martin's Flat, Isles of Scilly. Ameiropsis martinis sp. nov. appears most closely related to A. australis Kunz, 1975 Kunz, H. 1975. Copepoda Harpacticoidea aus dem litoral des sudlichen Afrika. 1 Teil. Kiel Meeresforsch., 31(2): 179–212.  [Google Scholar] but can be distinguished from it by the shape of the rostrum and the armature of the operculum, female genital field and the male P5 baseoendopodal lobe. Sarsameira parexilis sp. nov. was originally identified as S. exilis T. and A. Scott, 1894 Scott, T. 1894. Additions to the fauna of the Firth of Forth. Part IV. 12th Annual Report of the Fisheries Board for Scotland, : 231–270.  [Google Scholar] but the females can be distinguished from S. exilis by their smaller body size and shape of the caudal ramus whilst the males can be distinguished by the 12-segmented antennule and four setae on the P5 baseoendopodal lobe. Ameira longispina sp. nov. is unique within the “Ameira” complex of genera and species because of the marked elongation of the inner spine on the basis of the male P1. This species is tentatively placed in Ameira Boeck, 1865, but has features which indicate that it probably occupies an intermediate position between this genus and Psammameira Noodt, 1952. The previously unknown males of Sarsameira perezi Bodin, 1970 Bodin, P. 1970. Copépodes Harpacticoides marins des environs de La Rochelle 1. Especes de la vase intertidale de Chatelaillon. Tethys, 2(2): 385–436.  [Google Scholar] and Nitocra elegans (T. Scott, 1905 Scott, T. 1905. On some new and rare Crustacea from the Scottish seas. 23rd Annual Report of the Fisheries Board for Scotland, : 141–153.  [Google Scholar]) are also described.

A key to the world species of Coecobrya is given.     

Two new species of Pogonognathellus (Collembola: Tomoceridae) from China,with a discussion of East Asian species

Thirteen species of the genus Pogonognathellus Paclt, 1944 Paclt, J. 1944. Nomina nova in Collembola. Entomol Listy, 7: 92 [Google Scholar] have been reported worldwide, two from East Asia. Two new species of the genus from Jilin Province, northeast China are described here. Pogonognathellus heterochros sp. nov. is characterized by its unique body colour. Pogonognathellus mai sp. nov. is most similar to Pogonognathellus beckeri (Börner, 1909) but differs from it mainly in maxilla and tenaculum. A key to the East Asian species is provided, and the confusion among these species is discussed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:902CD044-0A58-4CCF-A1B1-449C9DE10938     

Two new Richtersia species from the northern Beibu Gulf,China

Two new species of the genus Richtersia Steiner, 1916 Steiner, G. 1916. Freilebende Nematoden aus der Barentssee. Zool Jb (Syst), 39: 511–676.  [Google Scholar] from the northern Beibu Gulf, China are described: Richtersia beibuwanensis sp. nov. is characterized by the presence of multispiral amphids with 3.5 turns in the male and unispiral amphids in the female, the numerous and irregular short spines in the cervical region, regular rows of spines in the mid-body region, and with the two unequal spicules. Richtersia coifsoa sp. nov. is characterized by the regular arrangement of longitudinal rows with long spines, the six prominent horns in the cuticular collar, large flattened unispiral amphids in the male, 100% of corresponding head width, the presence of two unequal spicules, and the much smaller flattened unispiral amphids in the female.http://www.zoobank.org/urn:lsid:zoobank.org:pub:32C87AF7-9F3A-47A5-BFD8-4A6279562308     

Two new species of the genus Chilibathynella Noodt, 1963 and Onychobathynella bifurcata gen. et sp. nov (Crustacea: Syncarida: Parabathynellidae) from New South Wales,Australia

Two new species of the parabathynellid genus Chilibathynella Noodt, 1963 Noodt, W. 1963. Estudios sobre Crustaceos de aguas subterraneas, III. Crustacea Syncarida de Chile Central. Investig Zool Chilenas, 10: 151–167.  [Google Scholar] are described from Australia. Chilibathynella joshuai sp. nov. has a unique combination of morphological characters, which includes five-segmented antenna, no epipodite on thoracopod I, two setae on the endopod of the male thoracopod VIII, homonomous row of 17 spines on uropodal sympod, uropodal exopod with four distal spines and a flat anal operculum. Chilibathynella digitus sp. nov. has two exclusive characters: six teeth on the pars incisiva of the mandible and a large, elongated digitiform protuberance (resembling a finger) on the basipod of male thoracopod VIII. The species also displays a unique combination of morphological characters, which includes five-segmented antenna, no epipodite on thoracopod I, no outer marginal seta on the first and second segments of the endopod of thoracopod I to VII, two setae on the endopod of the male thoracopod VIII, homonomous row of 12 spines on uropodal sympod, uropodal exopod with three distal spines and an unprotruded anal operculum. The two new species extend the distribution of the Chilibathynella genus in Australia from Victoria to New South Wales. A new genus and species of the family Parabathynellidae, Onychobathynella bifurcata gen. nov. sp. nov., is described from New South Wales, Australia. The new genus displays an evolutionary novelty, for Parabathynellidae and the entire group of Bathynellacea: the antennule, antenna, thoracopods, pleopod I and uropod have setae that are strong, thick, short, barbed and claw-like. This new genus is the first in the family without smooth setae on the antennule and antenna. The new genus also has a combination of characters that makes it unique in Parabathynellidae: the antennule is eight-segmented like Octobathynella Camacho and Hancock, 2010 Camacho, AI and Hancock, P. 2010. A new record of Parabathynellidae (Crustacea, Bathynellacea) in Australia: a new genus and species from New South Wales. J Nat Hist, 44(17–18): 1081–1094. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]; the antenna is five-segmented; the labrum has 20 teeth; the exopod of thoracopod I to VII has only one segment; the endopod lacks dorsal setae on the first segment and the epipod is absent from thoracopod I; first pleopods are present and resemble two barbed curved claws; there are 18 bifid spines on the sympod, two spines and four setae resembling strong barbed claws on the endopod and six robust setae on the exopod of the uropod.     

On a freshwater species of the genus Sanyuania Zhao and Han, 1980 (Crustacea,Ostracoda, Loxoconchidae) from Thailand,with a discussion on morphological evolution of the freshwater Loxoconchidae

The genus Sanyuania Zhao and Han, 1980 Zhao, G. and Han, D. 1980. “Late Quaternary brackish‐water ostracod faunas from the area to the west of Weishanhu Lake, Jiangsu and their significance.”. In Papers on Marine Micropaleontology, Edited by: Wang, P. 120–129. Beijing (China): Ocean Press.  [Google Scholar] is here transferred from the Cytherideidae to the Loxoconchidae, based on the morphology of valves and soft parts. Sanyuania segersi sp. nov., is described from a freshwater habitat, a river, in Thailand. This is the first record of this genus in Southeast Asia. The new species has a number of remarkable characters distinguishing it from other members in the genus and family: invicidont hinge, spearhead‐like protruding posterior extremity of carapace in dorsal view, subtriangular shape of carapace in lateral view, sieve plate without a central seta (sensillum) and an aberrant chaetotaxy of first and second antennae. The new taxon is compared with other recent freshwater loxoconchids [Cytheromorpha fuscata (Brady, 1869 Brady, G. S. 1869. Contributions to the study of the Entomostraca. IV. Ostracoda from the River Scheldt and the Grecian Archipelago.. Ann Mag Nat Hist ser 4., 3: 44–50.  [Google Scholar]), Elofsonia baltica (Hirschmann, 1909), Loxoconcha elliptica Brady, 1868, Loxoconcha galilea Lerner‐Seggev, 1968, Pseudolimnocythere hartmanni Danielopol, 1979 Danielopol, D. L. 1979. On the origin and the antiquity of the Pseudolimnocythere species (Ostracoda, Loxoconchidae).. Biol Gallo‐Hellen., 8: 99–107.  [Google Scholar], Pseudolimnocythere hypogaea Klie, 1938 Klie, W. 1938. Ostracoden aus unterirdischen Gewässern in Süditalien.. Zool Anz., 123: 148–154.  [Google Scholar]] using (1) phylogenetic analyses and (2) analyses of the chaetotaxy of the first antenna and second and third thoracopods, by comparison with an ontogenetic series of Loxoconcha japonica Ishizaki, 1968. The results from both types of analyses are congruent and reveal that Sanyuania segersi sp. nov., Pseudolimnocythere and Loxoconcha are in a more derived clade in the Loxoconchidae and are closely related to each other, whereas Cytheromorpha and Elofsonia are more ancestral.     

Morphological studies on a new species of Orthodonella,with redescription of O. gutta (Cohn, 1866) Kahl, 1931 (Protozoa: Ciliophora: Synhymeniida) from coastal water off Qingdao,China

The morphology and infraciliature of two marine synhymeniid ciliates, Orthodonella apohamatus nov. spec. and Orthodonella gutta (Cohn, 1866 Cohn, F. 1866. Neue infusorien im seeaquarium. Zeitschrift für wissenschaftliche Zoologie, 16: 253–302.  [Google Scholar]) Kahl, 1931 Kahl, A. 1931. Urtiere oder Protozoa I: Wimpertiere oder Ciliata (Infusoria) 2. Holotricha außer den im 1. Teil behandelten Prostomata. Tierwelt Deutschlands, 21: 181–398.  [Google Scholar], collected from coastal water off Qingdao, China, were studied on living cells and using protargol silver impregnation. The diagnosis for O. apohamatus nov. spec.: marine Orthodonella with length×width about 60–160×20–35?µm in vivo; lanceolate body shape with conspicuous beak-like projection at anterior end; 42–60 (mean 53) somatic kineties, including 28–42 on ventral and 13–20 on dorsal side; synhymenium with about 54–62 dikinetids; pharyngeal basket composed of 8–13 rods; four contractile vacuoles, two in middle near left margin and two at posterior end of cell; one elongated macronucleus and one micronucleus. Based on a Qingdao population, an improved diagnosis for the poorly known species, O. gutta is suggested: marine Orthodonella in vivo about 140–200×60–100?µm; body widely ellipsoidal with contractile beak-like anterior end; 62–74 (mean 66) somatic kineties with ca 41–48 ventral and 20–26 dorsal; synhymenium consisting of 43–70 dikinetids; 11–14 pharyngeal rods; one to several contractile vacuoles distributed in caudal area of cell; numerous cortical granules tiny and colourless; one ovoid macronucleus.

New and little‐known earthworm species from the Ivory Coast (Oligochaeta: Acanthodrilidae: Benhamiinae and Eudrilidae)

In the framework of the international project called “Conservation and Sustainable Management of Below‐Ground Biodiversity”, soil macrofauna collections were carried out in the Centre‐West Ivory Coast. Altogether, 13 earthworm species were recorded, of which four belonged to the family Eudrilidae and nine to the family Acanthodrilidae. From the species collected, two, Dichogaster (Dichogaster) eburnea sp. nov. and Dichogaster (Dichogaster) mamillata sp. nov., proved to be new to science. To accommodate the enigmatic eudrilid earthworm species Scolecillus compositus Omodeo, 1958 Omodeo, P. 1958. Oligochetes. In, La reserve naturelle integrale du Mont Nimba.. Memoire de la Institut Francais Afrique Noire, 53: 9–109.  [Google Scholar], a new genus, Lavellea gen. nov., is proposed.     

The Tanaidacea (Crustacea,Peracarida) of the North-East Atlantic: the shelf and bathyal Paratyphlotanais of the ‘Atlantic Margin’

Increasing oil-exploration activity and associated ecological surveying west of the Shetlands is leading to the discovery of many poorly known or undescribed tanaidaceans. Three species of the typhlotanaid genus Paratyphlotanais Kudinova-Pasternak and Pasternak, 1978 Kudinova-Pasternak R. K Pasternak F. A 1978 Deep sea Tanaidacea collected from the Caribbean Sea and Puerto Rico trench during the 16th cruise of RV ‘Akademik Kurchatov’ and the resemblance between the fauna of deep-sea Tanaidacea of the Caribbean region and the Pacific Trudy Instituta Okeanologiii. Akademiya Nauk SSSR, 113, 115–135 (in Russian)  [Google Scholar] have been recorded from shelf and bathyal depths between Iceland, the Faroe Islands and the western margin of the British Isles. Two, P. gracilipes (Hansen) and P. microcheles (G. O. Sars), formerly belonging to the genus Typhlotanais, are redescribed and a new species is described. A key to their identification is included. Inhabiting largely discrete zoogeographic areas, these species help define regional macrofaunal associations.
