Un type nouveau d'appareil stridulant accessoire pour les Cicadoidea Révision de la classification supérieure de la superfamille [Hom.]

Résumé

Jusqu'à présent on connaissait trois types d'appareils sonores pouvant se rencontrer chez les Cicadoidea ou Cigales proprement dites: l'organe cymbalique, le plus important et le plus original; le mécanisme stridulant accessoire, homélytro-mésonotal, trouvé en 1907, chez les Tettigades et genres apparentés et caractérisant depuis la sous-famille des Tettigadinae; le type ydiellien, alairohomélytral, que l'auteur a fait connaître en 1973. Dans cet article on signale d'abord, et apparemment pour la première fois, que le type tettigadien existe aussi chez quelques Tibicininae et quelques Cicadinae, puis un quatrième type d'appareil sonore est décrit: le ‘type moanien’, homélytro-mésoscutellaire découvert sur Moana expansa Myers. Comme la classification supérieure des Cigales est principalement basée sur les différents systèmes sonores et leurs modifications, les nouvelles données ont conduit à proposer une révision, avec une clé, des familles et sous familles.     

New species of cave-dwelling beetles (Coleoptera: Carabidae: Trechinae) from the Azores

The cave-dwelling beetles, Trechus pereirai, new species, and Trechus oromii, new species, and the epigean Trechus terrabravensis, new species, from the Azores islands are described. The male of the cave-dwelling beetle Trechus jorgensis Oromí and Borges is described for the first time. Affinities between Trechus species from the Azores and from other Macaronesian archipelagoes are discussed based on the morphology of the aedeagus. Ecological data are also included.

Nesta contribuição são descritos para os Açores os escaravelhos cavernícolas, Trechus pereirai, nova espécie, e Trechus oromii, nova espécie, e ainda o escaravelho epígeo Trechus terrabravensis, nova espécie. É feita pela primeira vez a descrição do macho da espécie cavernícola Trechus jorgensis Oromí & Borges. Com base na morfologia da genitália masculina são discutidas as afinidades com as outras espécies de Trechus dos Açores e outros arquipélagos Macaronésicos. Incluem-se ainda dados ecológicos.     

Calanoides natalis Brady, 1914 (Copepoda: Calanoida: Calanidae): identity and distribution in relation to coastal oceanography of the eastern Atlantic and western Indian Oceans

Until recently, Calanoides carinatus s.l. was assumed to be very widespread in the upwelling systems of the Atlantic, Indian and western Pacific Oceans. Molecular data, reported here, show that Calanoides from the eastern Atlantic and Arabian Sea are one species and distinct from C. carinatus s.s. The name Calanoides natalis Brady, 1914 is available for this species, which is fully re-described. The illustration by Brady of the male fifth leg and the currently reported genetic data lead us to conclude that C. natalis is distributed from the Bay of Biscay southwards along the eastern Atlantic, around the Cape of Good Hope, and northwards along the western boundary of the Indian Ocean as far as the Arabian Sea. A by-product of this study is the recognition that Calanoides macrocarinatus is a junior synonym of Calanoides brevicornis. Females of C. natalis are easy to distinguish morphologically from C. carinatus s.s. but are more similar to C. brevicornis, apart from size differences. From physical oceanographic evidence we conclude that the Indian Ocean is currently the upstream part of the distribution of C. natalis. Calanoides philippinensis is known to extend into the eastern Indian Ocean at tropical latitudes. It is not known if it is C. philippinensis that has been recorded along the western coast of Australia. An apparently undescribed species of Calanoides occurs on the eastern Australian coast.     

Description of four new species of the genus Ampelisca (Amphipoda,Ampeliscidae) from the northeastern and southeastern coasts of Brazil and designation of a neotype for Ampelisca soleata Oliveira, 1954

The present study raises the number of Ampelisca species recorded from the Brazilian coast from 18 to 21. The amphipod fauna of the Brazilian northeast coast is hardly known compared to that of the southeast coast. In this study, we describe three new species from the northeast coast: Ampelisca pseudobicarinata sp. nov., Ampelisca rocasensis sp. nov. and Ampelisca cristianae sp. nov, recorded previously as Ampelisca aff. lobata (Serejo et al. 2000 Serejo, CS, Wakabara, Y and Valério-Berardo, MT. 2000. Taxonomy and geographic distribution of Ampelisca (Amphipoda: Gammaridea) from the Brazilian coast. Polsk Archiw Hydrobiol., 47(3–4): 495–510.  [Google Scholar]). We also report a new record of Ampelisca burkei Barnard and Thomas, 1989 Barnard, JL and Thomas, JD. 1989. A new species, Ampelisca burkei, (Crustacea, Amphipoda) from Florida. Proc Biol Soc Washington., 102(2): 375–384.  [Google Scholar]. From the southeast coast a new species Ampelisca angraensis sp. nov. is described. An obscure species, Ampelisca soleata, which is very similar to Ampelisca brevisimulata, is herein redescribed and a neotype is designated. An updated key with all species of Ampelisca recorded from the Brazilian coast and comments on geographic distribution are given.     

Coral‐inhabiting barnacles (Cirripedia; Thoracica; Balanomorpha; Pyrgomatinae) from east of 150°W

The absence of coral‐inhabiting barnacles in the eastern Pacific has been generally accepted. Examination of corals collected on seven islands of French Polynesia, presently found in the collection of the Muséum national d'Histoire naturelle, Paris, revealed the presence of four known species of coral‐inhabiting barnacles, Cantellius tredecimus, Trevathana dentata, T. paulayi, and Neotrevathana elongata, and two new species, Trevathana tureiae and Savignium tuamotum. The present report extends the distribution of the pyrgomatines further east and south of their previously documented distribution.     

The fishes of Saint Helena Island,South Atlantic Ocean. II. The pelagic fishes

The pelagic fishes of St Helena Island, South Atlantic Ocean (15°58′S 5°43′W) are reviewed. A checklist of 53 taxa of pelagic fishes, with notes on fisheries significance, ecology and geographical distribution, is presented. Twelve of the taxa have not before been recorded at St Helena. Of particular interest are records of three primarily Indo-Pacific species: Decapterus muroadsi (Temminck and Schlegel), Uraspis helvola (Forster) and Scomberomorus commerson (Lacepède). Apart from U. helvola, which is known also from Ascension Island, these species are not otherwise recorded in the Atlantic Ocean.

Of the 49 pelagic fishes whose identities are clear, 81·6% are wide-ranging species known from both the Atlantic and Indo-Pacific regions, 12·2% are pan-Atlantic warm-water species and 4·1% are eastern Atlantic species which reach their western limit in the central Atlantic. In addition, the subspecies Platybelone argalus trachura is found only at St Helena and Ascension.

The principal pelagic species caught by St Helena fisheries are Katsuwonus pelamis, Thunnus albacares, T. obesus, T. alalunga, Scomber japonicus, Acanthocybium solandri and Pseudocaranx dentex, which together accounted for almost 95% of fish landings in 1982–1983 fiscal year.     

A new genus of cyclostome bryozoan from the European Atlantic coast

We have studied the type and other specimens of Stomatopora calypsoides (Jullien, ) collected in the NE Atlantic off the coast of the NW Iberian Peninsula and held in the Muséum national d'Histoire naturelle (Paris). We consider that this species should be placed in a new genus, Jullienipora gen. nov., because of its budding and branching patterns, and the presence and peculiar positioning of heterozooids. Assignment of this genus to a specific family must wait for the re‐organization of the family Stomatoporidae.     

Diplecogaster tonstricula,a new species of cleaning clingfish (Teleostei: Gobiesocidae) from the Canary Islands and Senegal,eastern Atlantic Ocean,with a review of the Diplecogaster-ctenocrypta species-group

The Diplecogaster-ctenocrypta species-group is reviewed; it comprises two species. The clingfish Diplecogaster ctenocrypta from the Canary Islands is redescribed. The new species Diplecogaster tonstricula, a facultative cleaner of other teleosts, is described on the basis of eight specimens and colour photos from Senegal and the Canary Islands, eastern Atlantic Ocean. The species is small, apparently not exceeding 23 mm total length; it is characterised by having nine dorsal-fin rays, eight anal-fin rays, 24–25 pectoral-fin rays, 14–15 principal caudal-fin rays, 13–16 rakers on third gill arch, pelvic disc without lateral papillae in region A, disc region B with two rows of weak papillae, interorbital distance 4.1–4.6 in head length, distance between disc and anus 14–17% of SL, head and body with 10–13 narrow vertical brownish bars, cheek with a white ocellus surrounded by black, and with a small black spot in the middle. The new species is compared with other species of the genus; a key to the six known species of the eastern Atlantic, Mediterranean and Black Sea and South African genus Diplecogaster is presented. A checklist is provided for the species of Diplecogaster and their synonyms.     

A new genus and species of Neotropical Anacolini and new distributional records (Insecta,Coleoptera, Cerambycidae)

A new genus is described: Acanthocornis gen. nov., type species, Acanthocornis flavus sp. nov. from Brazil, Pará. A new species is described: Atrocolus guarani sp. nov. from Paraguay, Cordillera, which differs from Atrocolus mariahelenae Monné and Monné, 2008 Monné, MA and Monné, ML. 2008. Atrocolus mariahelenae, novo gênero e espécie de Anacolini (Coleoptera, Cerambycidae). Iheringia Sér Zool, 98(2): 215–217. [Crossref], [Web of Science ®] , [Google Scholar] principally by the sparse punctures in the occiput and pronotum and by the dull interspaces between elytral carinae. We present new distributional data for Myzomorphus gounellei Lameere, 1912 from Brazil, São Paulo, and Biribellus martinsi Galileo, 1987 Galileo, MHM. 1987.

Revision of Flabelliderma Hartman, 1969 (Polychaeta: Flabelligeridae)

The flabelligerid genus Flabelliderma Hartman, 1969 Hartman, O. 1969. Atlas of the sedentariate polychaetous Annelids from California, 812Los Angeles: University of Southern California, Allan Hancock Foundation.  [Google Scholar] is redefined and its type species is re‐established. In comparison with Flabelligera Sars, 1829 Sars, M. 1829. Bidrag til Söedyrenes Naturhistorie; Förste Hæfte, 60Bergen: Dahl.  [Google Scholar], the diagnostic features include the fusion of papillae forming tubercles, often adhering sediment particles, and notopodial lobes forming large ovoid lobes. Four species are described and presented as new combinations, and three others were previously undescribed; thus the species included are F. papillosa (Essenberg, 1922 Essenberg, C. E. 1922.

Biometry of brooding in seven species of amphipod (Crustacea) from the Clyde Sea area

Brood size was found to be correlated linearly with female body length in all species studied, except Ampelisca macrocephala, which is usually a single brooded species. Of the six multi-brooded species, Lembos websteri, Stegocephaloides christianiensis, Echinogammarus pirloti and Gammaropsis nitida produced small numbers of large eggs in the winter and large numbers of small eggs in the summer. In Bathyporeia pilosa larger numbers of smaller eggs were produced by the overwintering generation. In Corophium bonnellii, both maximum and minimum brood sizes were produced by the summer generation. The largest broods relative to female body size were produced by the smaller species. In L. websteri, C. bonnellii and B. pilosa mean female size was smaller in the summer than the winter generation.
