This work is the last of four papers of the Spaghetti Project, aiming to revise the species of terebellids, a.k.a. “spaghetti” worms, present in the European French waters. In this last paper the Terebellidae, sensu stricto, from French waters are revised based, on material available in the French marine stations, type materials stored in the MNHN collection and newly collected specimens. Nine new species are described using both morphological and molecular tools: Eupolymnia gili n. sp., E. lacazei n. sp., E. meissnerae n. sp., Lanice kellyslateri n. sp., Paramphitrite dragovabeci n. sp., Pista labruneae n. sp., P. miosseci n. sp., P. sauriaui n. sp., and Terebella banksyi n. sp. European species of Eupolymnia are distinguished mainly by the shape of the lateral lobes and the size of the branchial stems. The two species belonging to Lanice genus are distinguished by the fusion of the first ventral shields, the shape of both noto- and neuropodia, and the pigmentation of the upper lip. The two species of Paramphitrite are distinguished by the presence or absence of a medial dorsal gap between the pairs of branchiae, by the shape of the lateral lobes and the presence or absence of a nephridial papilla on segment 4. The different species of Pista are distinguished by the number of pairs of branchiae, the shape of the lateral lobes and uncini. Finally, the two species of Terebella are distinguished by the number of segments with nephridial and genital papillae and the segments on which the branchiae occur. An identification key for European species of Terebellidae sensu stricto is also provided.

Telothelepodidae and Thelepodidae from French waters are revised based on material available in French marine stations and newly collected specimens. This work is the second part of the Spaghetti Project aiming to revise French species of “Spaghetti” worms. It describes three new species using both morphological and molecular tools: Streblosoma cabiochi n. sp., Streblosoma lindsayae n. sp. and Thelepus corsicanus n. sp. This study also permitted us to detect the presence of an Asiatic species, Thelepus japonicus, in Arcachon Bay and Normandy, introduced via oysters transfers. An identification key for European species of both families is also provided.

Trichobranchidae from French waters are revised based on material available in French marine stations and newly collected specimens. This research is the first part of the “Spaghetti Project” aiming to revise French species of terebellids and trichobranchids. It confirms the absence of the so-called cosmopolitan species Terebellides stroemii from French waters, and describes eight new species of Terebellides: T. bonifi n. sp., T. ceneresi n. sp., T. europaea n. sp., T. gentili n. sp., T. gralli n. sp., T. lilasae n. sp., T. parapari n. sp. and T. resomari n. sp. and one species of Trichobranchus: T. demontaudouini n. sp. using both morphological and molecular tools. An identification key for all European species of Trichobranchidae is provided.

Four species ofLaonice(Annelida: Spionidae) were collected from the lower bathyal depths (3300–3700 m) in the Whittard Canyon, NE Atlantic. Two are herewith described as new species:Laonice whittardensissp. nov. andLaonice nataesp. nov. The other two areLaonice blakeiSikorski & Jirkov, 1988 andLaonice magnacristataMaciolek, 2000.Laonice whittardensishas genital pouches appearing from chaetiger 3, prostomium free of peristomium and bidentate hooks.Laonice nataebelongs to the subgenusAppelloefianov. with prostomium distinct from the peristomium, more than two vertical rows of capillaries in several anterior chaetigers, genital pouches present on a limited number of segments or totally absent. However, the absence of pronounced anterior widening of the body together with anterior branchiae, which are remarkably (nearly twice) longer than the notopodial postchaetal lobes, the narrow lanceolate notopodial postchaetal lobes, the pronounced pointedness of all postchaetal lobes (both notopodial and neuropodial) in the anterior half of body at least, and absence of genital pouches and the size of the body all distinguishL. nataefrom other species belonging to this subgenus. An identification key to all nine known deep-water (>400 m depth)Laonicespecies in North Atlantic is given and four previously recognized sub-generic groups are formally named:Laonice, Sarsianasubgen. nov.,Appelloefiasubgen. nov.,Norgensiasubgen. nov.

AbstractAmong fish parasitic nematodesRhabdochonais one of the most speciose genera, withc.100 species. Twelve congeneric species occur in Mexican freshwater fishes, in a region located between the Nearctic and Neotropical biogeographical regions. Host association and biogeographical history have determined the high species richness ofRhabdochonain Mexico. One of these species,Rhabdochona mexicana, is highly specific to the characid genusAstyanax.Characids are a group of freshwater fish with Neotropical affinity. In this paper, we explore the genetic diversity ofR. mexicanathrough samples obtained from populations ofAstyanaxspp. across river basins of Mexico and Guatemala. Sequences of one mitochondrial and two ribosomal genes were obtained from 38 individuals and analysed using Maximum Likelihood and Bayesian Inference analysis. Phylogenetic analyses usingcox1, and a concatenated alignment of 18S + 28S +cox1 recovered two genetic lineages. One of them corresponded withR. mexicana sensu stricto; this lineage included three reciprocally monophyletic subgroups; the other lineage was highly divergent and represented a putative candidate species. A detailed morphological study was conducted to corroborate the molecular findings. We describe a new species herein and discuss the implications of using molecular tools to increase our knowledge about the diversity of a speciose genus such asRhabdochona.

AbstractExamination of 122 specimens ofXanthogrammaSchiner, 1861 (Diptera: Syrphidae) from varied localities in Europe (+Turkey) resulted in the description of two new species (X. aeginaeRicarte, Nedeljković, and Vujićnew speciesandX. pilosumNedeljković, Ricarte, and Vujićnew species), as well as new data on six other species. Most of the examined material originated from the Balkan Peninsula and Greek islands. New species concepts were supported by morphological and molecular evidence. Relationships among the eight studied species were analysed and discussed based on the data of nuclear (ITS2) and mitochondrial (COI) genes sequences. An identification key to the European species ofXanthogrammais provided. Lectotypes are designated forDoros decoratumZetterstedt, 1843,Lasiophthicus novusRondani, 1857,Syrphus laetusFabricius, 1794,Syrphus ornatusMeigen, 1822, andXanthogramma nobilitatumFrey, 1946.

Drapetis is a genus of tiny predaceous hybotid flies found frequently on the bark of trees. From a single locality in province Skåne (S Sweden) we report the co-existence of seven species of Drapetis. One is new and described as D. abrollensis sp. nov., and four species, D. assimilis (Fallén), D. completa Kovalev, D. infitialis Collin and D. stackelbergi Kovalev, are relatively recent additions to the list of Swedish Diptera. A key to males of the 14 species of Drapetis known from NW Europe is given. Special emphasis is given to modifications of the midleg cuticle observed in males of several species that belong to the D. exilis-species group. As shown by SEM images these modifications differ greatly between the species, both at light microscopic and ultrastructural levels. These modifications are introduced as a new set of characters in the identification key. Finally, brochosomes were detected on the midleg of three SEM-examined Drapetis species, documenting indirectly that small leafhoppers are regularly used as prey.

Endogeophilus ichnusae gen. et sp. nov. (Chilopoda: Geophilidae sensu stricto) is described based on three specimens from two localities in south-western Sardinia, examined by light and scanning electron microscopy. The new centipede resembles the rare Ibero-Pyrenean genus Galliophilus Ribaut & Brolemann, 1927 in some features, especially in the forcipular segment, and the temperate European species Geophilus electricus (Linnaeus, 1758) in other features, especially in the ultimate leg-bearing segment. However, the true affinities of E. ichnusae gen. et sp. nov. are uncertain, because the new species departs significantly from the majority of geophilids for the higher number of legs (91–107 pairs in the specimens examined), the slender trunk segments (the sternites being longer than wide), the relatively stout legs (the tarsus being only about twice as long as wide) and the very short setae (≤ 15 mm) scattered on the body surface. All these features are probably derived and suggest adaptation to a more strictly endogeic habit than other geophilids.

Under the principle of priority, Memecylon liberiae is the correct name for the West African species previously known as M. aylmeri. A lectotype is designated for M. liberiae from the original material rediscovered in the Berlin herbarium. Use of the neotype designated by Jacques-Félix must therefore be abandoned. A new species M. emancipatum is proposed to replace M. liberiae sensu Jacques-Félix. A revised identification key is provided for the West African species of Memecylon sensu stricto.

In two European species of the genus Plutomurus Yosii, P. carpaticus Rusek & Weiner and P. unidentatus (Börner), several diagnostic morphological characters are specified and illustrated: body chaetotaxy, number of internal spine-like chaetae on tibiotarsi and number of teeth on claw. The contribution is based on the study of type specimens of both species and specimens of other populations of their distribution ranges. The numerous specimens of the genus Plutomurus collected recently in the Western Carpathian caves are the most similar to P. carpaticus, but differ in macrochaetotaxy and may represent a new species. Three types of macrochaetae on thorax and abdomen of Plutomurus congeners from the Europe and Caucasus are defined. Identification key to European Plutomurus species is provided.

A new species of the genus Birdantis Stål, 1863 (Hemiptera: Fulgoridae), B. bhaskarai sp. nov. from Larat Island (Tanimbar), is described. Birdantis collaris (Walker, 1870) stat. rev. and B. trilineata (Schmidt, 1926) stat. rev. are reinstated as valid species, respectively from status of subspecies and as junior synonym of B. delibuta Stål, 1863. These four species, as well as the other one previously described from the Maluku Islands, B. decens Stål, 1863, are illustrated from their type specimens. An identification key, a distribution map, illustrations of habitus and details of male genitalia are provided. The synonymy between Myrilla Distant, 1888 and Birdantis is formally reinstated and all species formerly placed in the subgenus Birdantis (Myrilla) are transferred to Birdantis sensu stricto. Birdantis is transferred to the subfamily Aphaeninae Blanchard, 1847 and now contains eighteen species distributed in Maluku (five species), New Guinea and neighbouring islands (ten species) and Australia (three species).
