Anatomical characters and systematics of Anodontites trapesialis (Lamarck, 1819) from South America (Mollusca, Bivalvia, Unionoida, Muteloidea)
TLDR
A group of anatomical data is referred to, exclusive for this species, that may be analized to identify this wide‐ranging South‐American species, with such a variable shell. Expand
Thala crassa new species of costellariidae (Gastropoda, muricoidea) from the southern coast of Brazil
TLDR
Thala crassa is described from deep water off Sao Paulo, Brazil, but the anterior oesophagus and proboscis are very long and the penis has a rounded tip and the prostate is claviform. Expand
Population structure and identification of two matrilinear and one patrilinear mitochondrial lineages in the mussel Mytella charruana
TLDR
The heterogeneity among Brazilian populations requires that relocation for aquaculture be preceded by genetic identification of the haplogroups, and detailed data on temperature, pH, salinity and local currents could help explain the genetic structuring observed among populations of Brazilian M. charruana. Expand
Addisonia enodis, a new species of Addisoniidae (Mollusca, Archaeogastropoda) from the Southern Brazilian coast
Addisonia enodis, a new species of Addisoniidae from deep waters off Southeastern Brazil is described, the first record of this family in the South Atlantic. Shell, radula and anatomical charactersExpand
Genetic relationships among freshwater mussel species from fifteen Amazonian rivers and inferences on the evolution of the Hyriidae (Mollusca: Bivalvia: Unionida).
TLDR
The present molecular findings support traditional taxonomic proposals, based on morphology, for the South American subfamily Hyriinae, currently divided in three tribes: Hyriini, Castaliini and Rhipidodontini, and indicate that Paxyodon syrmatophorus and Prisodon obliquus are more closely related, followed by Triplodon corrugatus.

ARTICLE Detection of mitochondrial DNA heteroplasmy suggests a doubly uniparental inheritance pattern in the mussel Mytella charruana
TLDR
Cytochrome oxidase c subunit I (COI) sequences provide evidence for the presence of mtDNA M in the gonad and adductor muscle of male M. charruana, a tropical estuarine mytilid, which is most likely due to the occurrence of DUI. Expand
CREPIDULA CACHIMILLA (MOLLUSCA: GASTROPODA), A NEW SPECIES FROM PATAGONIA, ARGENTINA
TLDR
These parameters neither coincide with those reported by Hoagland(1977) for the similar Californian Crepidula onyx, nor with the reproductive characters reported by Miloslavich & Penchaszadeh (2001) for Crepidulas aplysioides, which suppos-edly occurs in the region. Expand
Terebra reticulata, new species of Terebridae (Gastropoda, Prosobranchia, Conoidea) from southeastern Brazil
Terebra reticulata new species is described from deepwater off the southeastern Brazilian coast. The anterior portion of the digestive system is rather simple, without accessory structures. RadularExpand
