Four, morphologically similar species of crested newts (genus Triturus) meet and hybridize in Serbia, making a complex system with several hybrid zones. The puzzling and rapidly changing taxonomic status of crested newts has been a major issue in getting hold of their distribution. We provide an overview of the current knowledge on Triturus taxonomy and compile available faunistic data into a distribution map, highlighting the species contact and hybrid zones. At the present state of faunistic and genetic research, the northwestern , northeastern , Eastern and southeastern parts of Serbia transpire as areas that are exceptionally important for the diversity of crested newts.

Material Information

Because Onchidiidae (Mollusca: Gastropoda: Pulmonata) has been understudied since the last experts were active more than 70 years ago, systematics of this taxon is in a state of confusion: The nomenclatural status of most species names is unknown; the current supra-specific classification, largely based on Labbé’s work, has not been revised since the 1930s and needs to be re-evaluated through a modern, phylogenetic approach. A checklist of all 143 species names available in Onchidiidae is provided, as a first step towards a systematic revision. In addition, type material information (all existing types were examined by the author), type locality, and comments on the current taxonomic status and classification are provided for each species name. Present state of knowledge of the higher-level systematics of Onchidiidae is also briefly reviewed. Species diversity based on traditional generic taxa is presented. Finally, type localities are listed by region, worldwide, and interesting questions of biogeography are mentioned.

Current knowledge about the glycosylation of matrix metalloproteinases (MMPs) and the inhibitors of metalloproteinases (TIMPs) is reviewed. Whereas structural and functional aspects of the glycobiology of many MMPs is unknown, research on MMP-9 and MMP-14 glycosylation reveals important functional implications, such as altered inhibitor binding and cellular localization. This, together with the fact that MMPs contain conserved and many potential attachment sites for N-linked and O-linked oligosaccharides, proves the need for further studies on MMP glycobiology.

The taxonomic status of the widely distributed freshwater crab Potamonautes lirrangensis (Rathbun, 1904) sensu lato is revised because morphological and molecular evidence indicates that this taxon is a complex comprising more than one species. Four taxa are now recognized: Potamonautes lirrangensis (Rathbun, 1904) s. str. and P. kisangani sp. nov. from the Middle Congo River in Central Africa, P. amosae sp. nov. from the drainages of Lakes Kivu and Tanganyika, and P. orbitospinus (Cunnington, 1907) from Lake Malawi which had been previously synonymised with P. lirrangensis s. lat. Diagnoses, illustrations and distribution maps are provided for each of these taxa and they are compared to similar species from Central and Southern Africa.

Three New Species

A taxonomic revision of the pyramidellid genus Eulimella from Brazil was performed based on shell morphology. The holotype of Eulimella rudis Watson, 1886 is illustrated and compared to shells from the southeast Brazilian coast, this being the first confirmed record of this species after its original description. Eulimella smithii (Verrill, 1880), previously known from northern localities in the western Atlantic, is recorded from the southwestern Atlantic, along virtually the entire Brazilian coast; it is herein considered a distinct taxon from Eulimella unifasciata (Forbes, 1844), a very similar species from the eastern Atlantic, given the lack of data on development to consider an amphi-Atlantic distribution. Three new species are described: Eulimella torquata sp. nov., diagnosed by a constriction in the middle of each teleoconch whorl caused by a strong spiral furrow, producing a bilobed whorl profile; Eulimella cylindrata sp. nov., diagnosed by a large subcylindrical teleoconch; and Eulimella ejuncida sp. nov., characterized by its very slender shell, and small protoconch with only one whorl and with an “arc” shaped suture. The shells herein identified as Eulimella cf. calva from Brazil are conchologically identical to Eulimella calva Schander, 1994, from West Africa, but their taxonomic status should remain dubious because of lack of biological information to evaluate a possible amphi-Atlantic distribution pattern. All the species studied (except Eulimella ejuncida sp. nov.) have characteristic short microscopic axial threads organized in a spiral belt, varying in position and expression among species, but usually located in the middle of each teleoconch whorl or below the suture; this characteristic is also present in some species from the eastern Atlantic. Three South American species, originally or subsequently allocated in Eulimella, are herein considered as not belonging to this genus: Eulimella argentina Doello-Jurado, 1938; Eulimella bahiensis Castellanos, 1982; and Eulimella xenohyes (Melvill & Standen, 1912). The holotype of Eulimella lissa is illustrated with SEM micrographs.

Genetic variability of field populations of Grapevine leafroll-associated virus 2 (GLRaV-2) in Pacific Northwest (PNW) vineyards was characterized by sequencing the entire coat protein (CP) and a portion of the heat-shock protein-70 homolog (HSP70h) genes. Phylogenetic analysis of CP and HSP70h nucleotide sequences obtained in this study and corresponding sequences from GenBank revealed segregation of GLRaV-2 isolates into six lineages with virus isolates from PNW distributed in ‘PN’, ‘H4’, and ‘RG’ lineages. An estimation of the ratio of nonsynonymous substitutions per nonsynonymous site to synonymous substitutions per synonymous site indicated that different selection pressures may be acting on the two genomic regions encoding proteins with distinct functions. Multiple alignments of CP amino acid sequences showed lineage-specific differences. Enzyme-linked immunosorbent assay results indicated that GLRaV-2-specific antibodies from a commercial source are unable to reliably detect GLRaV-2 isolates in the RG lineage, thereby limiting antibody-based diagnosis of all GLRaV-2 isolates currently found in PNW vineyards. A protocol based on reverse-transcription polymerase chain reaction and restriction fragment length polymorphism analysis was developed for differentiating GLRaV-2 isolates belonging to the three lineages present in the region. The taxonomic status of GLRaV-2 is discussed in light of the current knowledge of global genetic diversity of the virus.

The rare Fissidens jansenii Sérgio & Pursell is reported on plateau de Millevaches, Limousin (France), nearly 1000 km north of the nearest known population. As a result, F. jansenii is known from the Iberian Peninsula and now from western France. An updated distribution map of the species in Europe is provided. The new material is fully described and illustrated and the ecology in France is outlined. Gametophytically, French specimens of F. jansenii do not deviate significantly from Portuguese material and the variability of characters is discussed. In France, on plateau de Millevaches, F. jansenii is relatively frequent but constitutes rather small populations, with a low number of individuals. Sporophytes were regularly encountered and reproduction is most likely to be by spore dispersal. On plateau de Millevaches, F. pusillus (Wilson) Milde shares a comparable habitat but is easily distinguished from F. jansenii. Morphologically similar species occurring in Western Europe and that could potentially be confused with F. jansenii (F. rivularis and F. rufulus Bruch & Schimp.) are compared.

Melanophryniscus orejasmirandai is a species of toad known only from two localities in southern Uruguay. This toad isthe southernmost suggested taxon of the M. tumifrons group, whose species are characterized by a glandular frontal swell-ing on the snout. The study of the type series of M. orejasmirandai and of M. pachyrhynus, along with observations madeon many specimens of both species suggested a close relationship between them. The analysis of the variation of snout-vent length, coloration pattern, relative size of the frontal swelling, and presence/absence of the metatarsal gland showedthat characters previously used to separate both species resulted of no diagnostic value. Further comparison of the externalmorphology, osteological characters, and partial sequences of the cytochrome b gene indicated that M. orejasmirandai isa junior synonym of M. pachyrhynus. Melanophryniscus pachyrhynus is characterized by a reticulated orange ventral pat-tern which is shared only with M. peritus, from which it differs by its smaller size. The ornamentation of the nasal bonesunderlying the frontal swelling in M. pachyrhynus seems to be characteristic of the M. tumifrons group. An updated distribution map of M. pachyrhynus and some new localities are also provided.
