Pace R. 2009. — Les Aleocharinae (Insecta, Coleoptera, Staphylinidae) de Nouvelle-Calédonie, avec la description de nouvelles espèces. Zoosystema 31 (4): 749-758.

Aleocharinae (Insecta, Coleoptera, Staphylinidae) from New Caledonia with description of new species.

Seven new species of Aleocharinae belonging to the tribes Homalotini (Lomaglossina giachinoi n. sp., L. amieuensis n. sp., Neidosphena miricornis n. sp., Nemoedia amieuensis n. sp.), Athetini (Aglaogaster giachinoi n. sp.) and Thamiareini (Thamiaraea kanak n. sp., Mimacrotona giachinoi n. sp.) are described and illustrated. The formerly unknown male of Nemoedia solitaria Pace, 1991 is illustrated. With the present paper, 125 species are known from New Caledonia, most of them endemic

Oliverio M. 2009. — Diversity of Coralliophilinae (Mollusca, Neogastropoda, Muricidae) at Austral Islands (South Pacific). Zoosystema 31 (4): 759-789.

The Coralliophilinae is a large subfamily of Muricidae, including 200–250 species that feed exclusively on anthozoans. The material collected during the expeditions BENTHAUS and RAPA 2002 at Austral Islands are reviewed. Twenty-eigth species are recorded, one species is described as new, Coralliophila australis n. sp., diagnosed by its large size and elongated shape. All but one species showed a planktotrophic development, 10 species (36%) were from shallow waters and 15 species (54%) from deep waters. The smaller proportion of deep water coralliophiline species (compared to the range and average on a global scale) in this marginal area of the Pacific, suggests that marginality may affect the deep water faunas more than the shallow water ones.

Four new extinct species of Endodontidae (Mollusca, Pulmonata) from Rurutu (Austral Islands, French Polynesia).

Four species of land snails belonging to the family Endodontidae (Mollusca, Pulmonata) are described, all of them are endemic to Rurutu Island (Austral Islands, French Polynesia): Australdonta collicella n. sp, A. magnasulcatissima n. sp., A. microspiralis n. sp. and A. sulcata n. sp. The number of species of Endodontidae known from Rurutu is increased from seven to 11. All of them are considered extinct.

Alonso M. & Garcia-de-Lomas J. 2009. — Systematics and ecology of Linderiella baetica n. sp. (Crustacea, Branchiopoda, Anostraca, Chirocephalidae), a new species from southern Spain. Zoosystema 31 (4): 807-827.

Linderiella baetica n. sp. (Anostraca, Chirocephalidae), is described from a temperate Mediterranean climate, episodic temporary fresh water body in Puerto Real (Cádiz, South Spain). Linderiella baetica n. sp. is characterized by the display of the shape of the basomedial outgrowth on the male second antenna, margin structure of praepipods, structure of medial margin of endopod, penis basal projections, horn-like process on the inner side of the female antenna, female genital somites and of a combination of morphological features involving egg morphology. The study includes a morphological analysis using optical and scanning electron microscopes. Based on the differential diagnosis, a dichotomous key for males, females and resting eggs to Linderiella species is proposed. The diagnosis is complemented with phenology of the species and accompanying fauna and aquatic vegetation, and physico-chemical evolution of water along monitoring.

Nguyen Duy-Jacquemin M. 2009. — Revision of the genera of Polyxenidae bearing pseudoarticulated gnathochilarial sensilla (Diplopoda, Polyxenida, Polyxenidae), with the description of two new species. Zoosystema 31 (4): 829-848.

Examination of the syntypes of the species Chilexenus rosendinus (Silvestri, 1903) and Macroxenodes meinerti (Silvestri, 1898) has allowed the revision of the four genera of the subfamily Macroxeninae Condé, 2008 bearing pseudoarticulated gnathochilarial sensilla. The diagnostic characters of each of these four tropical or subtropical genera — Chilexenus Silvestri, 1948, Macroxenodes Silvestri, 1948, Macroxenus Brölemann, 1917 and Afraustraloxenodes Nguyen Duy-Jacquemin, 2003 — are redefined and two new species of Macroxenodes are described: M. navassaensis n. sp. from Navassa Island (Greater Antilles) and M. jahynyi n. sp. from Uberlândia, Brazil. Identification keys to the genera and species are given.

Pariselle A. & Euzet L. 2009. — Systematic revision of dactylogyridean parasites (Monogenea) from cichlid fishes in Africa, the Levant and Madagascar. Zoosystema 31 (4): 849-898.

Systematic revision is made of the six dactylogyridean genera (Monogenea) described on African, Levantine and Malagasy cichlid fishes: Urogyrus Bilong Bilong, Birgi & Euzet, 1994 (including one species); Enterogyrus Paperna, 1963 (including eight species); Insulacleidus Rakotofiringa & Euzet, 1983 (including three species); Onchobdella Paperna, 1968 (including eight species); Scutogyrus Pariselle & Euzet, 1995 (including six species) and Cichlidogyrus Paperna, 1960 (including 71 species). Validities of species are discussed. Diagnoses and illustrated determination keys are given for all taxa.

Mantilleri A. 2009. — Révision des Higonius Lewis, 1883, et genres apparentés (Insecta, Coleoptera, Brentidae). Zoosystema 31 (4): 899-943.

Review of Higonius Lewis, 1883, and allied genera (Insecta, Coleoptera, Brentidae).

The genera Higonius Lewis, 1883, Taphrocomister Senna, 1895, Higonodes Zimmerman, 1994, Pseudohigonius Damoiseau, 1987, and Neohigonius Goossens, 2005, are revised. Five new species are described: Higonius apicalis n. sp. from Sulawesi, H. philippinensis n. sp. from Philippines and Taiwan, H. bituberculatus n. sp. and H. myersi n. sp. from New Guinea and, at last, H. spongiosus n. sp. from Borneo. Several new synonymies are established: Higonius niassicus Senna, 1893 = H. nudus Kleine, 1920; H. hirsutus Senna, 1893 = H. bilobicollis Senna, 1898 = H. malayanus Mantilleri, 2007. The distribution of each species is given. Following this taxonomic revision, a cladistic phylogenetic analysis was performed on 35 morphological characters of the adults; it confirms the validity of the basal genera Pseudohigonius and Neohigonius, but shows Higonius being polyphyletic if the monotypic genera Higonodes and Taphrocomister are not included. Consequently they are downgraded at the rank of subgenera of Higonius, and a new combination is proposed: Higonius (Taphrocomister) singularis (Senna, 1895) n. comb., and Higonodes novenarius (Damoiseau, 1987) becomes Higonius (Higonodes) novenarius Damoiseau, 1987 again. Species of the genus Higonius are distributed in three subgenera: Taphrocomister (with H. apicalis n. sp., H. grouvellei, H. reconditus and H. singularis), Higonodes (with H. niassicus, H. novenarius and H. philippinensis n. sp.) and Higonius s.s. (with H. angustirostris, H. bituberculatus n. sp., H. cilo, H. crux, H. hirsutus, H. myersi n. sp., H. perpusillus, H. poweri, H. spongiosus n. sp. and H. trisulcatus). A biogeographic hypothesis is finally proposed to explain the current distribution of the three genera Pseudohigonius, Neohigonius and Higonius.

Pickett K. M., Carpenter J. M. & Dejean A. 2009. — “Basal” but not primitive: the nest of Apoica arborea de Saussure, 1854 (Insecta, Hymenoptera, Vespidae, Polistinae). Zoosystema31 (4): 945-948.

The first nest of Apoica arborea ever collected is reported. Characteristics of the unusual nest design are discussed relative to other members of the genus Apoica and other epiponine genera. The characteristics of its nest architecture are a mosaic of primitive and derived features for the Polistinae, and thus the nest design is not properly interpreted as the primitive condition from which other swarm-founding wasp nest designs are derived. The frequent conflation of “basal” and primitive is discussed.

Castro P. 2009. — Two new species of Carcinoplax H. Milne Edwards, 1852, and Pycnoplax Castro, 2007, from the western pacific, and a description of the female of Thyraplax truncata Castro, 2007 (Crustacea, Decapoda, Brachyura, Goneplacidae). Zoosystema 31 (4): 949-957.

Two new species belonging to the family Goneplacidae MacLeay 1838 (Crustacea, Decapoda, Brachyura) are described from the western Pacific Ocean. The first belongs to Carcinoplax H. Milne Edwards, 1852, the second to Pycnoplax Castro, 2007. The new species of Carcinoplax is distinguished from the 18 known species of the genus by the morphologies of the first male pleopods and outer orbital and anterolateral teeth; the new species of Pycnoplax is distinguished from the five known species of the genus by the morphology of the first and second male pleopods and the granular carapace. A female specimen of a third goneplacid, Thyraplax truncata Castro, 2007, which was previously known only from male specimens, is also described. The characters of the two new species further confirm that in the Goneplacidae s.s. the morphology of the external reproductive structures rather than that of the carapace are far more reliable in showing phylogenetic relationships among supraspecific taxa.

De Smet W. H. & Verolet M. 2009. — On two new species of Proales from France, with reallocation of Dicranophorus liepolti Donner, 1964 and D. secretus Donner, 1951 (Rotifera, Monogononta). Zoosystema 31 (4): 959-973.

Two new species of rotifer, Proales ardechensis n. sp. and P. laticauda n. sp. (Monogononta, Proalidae) from the Ardèche, France, are described and illustrated. Proales ardechensis n. sp. is readily distinguished from its congeners by the stout foot composed of 4 pseudosegments of which the penultimate one bears an antenna at its posterior margin dorsally, and the malleate trophi bearing characteristic hook-shaped alulae. Proales laticauda n. sp. is characterized by its broad and stout truncate tail almost overlying the foot, and its small and slender basally swollen toes. Based on the trophi morphology studied by scanning electron microscopy Dicranophorus liepolti Donner, 1964 is reallocated to the genus Encentrum, and D. secretus Donner, 1951 is placed in the genus Aspelta.

Pelorce J. & Poutiers J.-M. 2009. — Une nouvelle espèce de Bathymodiolinae (Mollusca, Bivalvia, Mytilidae) associée à des os de baleine coulés en Méditerranée. Zoosystema 31 (4):975-985.

A new species of bathymodioline mussel (Mollusca, Bivalvia, Mytilidae) associated with sunken whale bones in the Mediterranean Sea.

Species of the genus Idas Jeffreys, 1876 (Mollusca, Bivalvia, Mytilidae), associated with sunken organic substrates in the Mediterranean Sea and the North-East Atlantic Ocean, are reviewed. A new species associated with old sunken whale bones “Idas” cylindricus n. sp., provisionally included in the genus Idas s.l., is described from the Gulf of Lion (western Mediterranean Sea). It is compared with Idas (s.l.) simpsoni (Marshall, 1900), the closest species and to other related species of the North-East Atlantic and Mediterranean Sea. The new species is characterised by a large size for the genus, inflated shape and rectangular outline, thick and brown internal ligament and the markedly anterior position of the umbo.

Les espèces du genre Idas Jeffreys, 1876 (Mollusca, Bivalvia, Mytilidae), associées à des substrats organiques coulés en profondeur en Méditerranée et dans l'Atlantique nord-est, sont passées en revue et une nouvelle espèce associée à de vieux os de baleine coulés «Idas» cylindricus n. sp., incluse provisoirement dans le genre Idas s.l., est décrite du Golfe du Lion (Méditerranée occidentale). Elle est comparée avec Idas (s.l.) simpsoni (Marshall, 1900) qui est l'espèce la plus proche, et avec les autres espèces voisines de l'Atlantique nord-est et de Méditerranée. La nouvelle espèce se caractérise par sa taille importante pour le genre, sa forme renflée et son profil rectangulaire, son ligament interne épais et marron et la position très avancée de l'umbo.

Prié V. & Bichain J.-M. 2009. — Phylogenetic relationships and description of a new stygobite species of Bythinella (Mollusca, Gastropoda, Caenogastropoda, Amnicolidae) from southern France. Zoosystema 31 (4): 987-1000.

A population of the aquatic gastropod Bythinella that does not conform to any described hypogean or epigean species of this genus was discovered in a cave stream in southern France (Folatière cave). Members of this population lacked body pigments and eyespots, which suggests adaptation to a subterranean environment. Mitochondrial COI sequences revealed two lineages within this population, separated by a genetic divergence higher than the inter-specific threshold commonly admitted for hydrobioid species. In contrast, a phylogeny based on the nuclear ITS1 gene clustered the sequenced hypogean specimens in a single clade. Moreover multivariate analyses performed on shell parameters did not enable discrimination between hypogean specimens attributed to each of these two mitochondrial lineages. The high COI variability within the same population and conflict between mtDNA and nDNA trees could be explained by a scenario of introgression by hybridization. Consequently, based on nuclear gene phylogeny, shell and anatomical characters, and ecological evidences, we hypothesize that the easily recognizable hypogean morph of the Folatière cave can be attributed to a distinct and new species — here described and named B. navacellensis n. sp. Our extensive sampling suggests that B. navacellensis n. sp. is distributed within a small delimited and cohesive area located around southern Larzac, covering c. 300 km². Considering its distribution, restricted to a few subterranean aquifers only, B. navacellensis n. sp. can be categorised as a vulnerable species, VU D2.
