A new species of Leiostracus from Bahia, Brazil (Gastropoda, Pulmonata, Orthalicidae) Iheringia, Sér. Zool.
Salvador,Rodrigo B.; Cavallari,Daniel C..
A remarkable new species of pulmonate snail was recently collected in a small Atlantic Rainforest fragment near the city of Canavieiras, state of Bahia, Brazil, an area known for a high diversity of land snails. It is described herein as Leiostracus fetidus sp. nov. and can be easily identified by its color pattern of irregular brown to black axial stripes on a white to yellow background, a reddish axial band "separating" the white peristome from the rest of the shell and a broad brown spiral band surrounding the umbilical region. Other diagnostic features include a relatively small size, a proto columellar fold and two very weak folds delimiting the basal region of the aperture. This discovery is a reminder of how little this fauna is known and also an...

A new species of Leiostracus (Gastropoda, Pulmonata, Orthalicoidea) from Espírito Santo, Brazil Iheringia, Sér. Zool.
Salvador,Rodrigo B.; Cavallari,Daniel C..
A remarkable new species of pulmonate land snail was found in the collection of the Senckenberg Forschungninstitut und Naturmuseum Frankfurt (Frankfurt am Main, Germany) and is described here as Leiostracus faerie sp. nov. It can be easily identified by its small and translucent shell with fine axial light brown bands and its protoconch sculpture. It was collected in the Rio Doce ("Doce River") region in Espírito Santo, Brazil, an area known for a high diversity and endemicity of land snails. This discovery shows how little this fauna is known and reinforces the importance of museum collections in the study of biodiversity and conservation.

Histologia das glândulas salivares dos Limacoidea e Milacidae (Gastropoda, Pulmonata) Zoologia
Leal-Zanchet,Ana Maria.
The histology of the salivary glands of six species of Limacoidea, Boettgerilla pallens Simroth, 1912, Deroceras laeve (Müller, 1774), Deroceras reticulatum (Müller, 1774), Deroceras rodnae Grossu & Lupu, 1965, Malacolimax tenellus (Müller, 1774) and Lehmannia marginata (Müller, 1774), and a species of Milacidae, Tandonia budapestensis (Hazay, 1881) is comparatively described herein. In the glandular parenchyme four to five secretory cell types are distinguished and characterised, besides a cell type which is probably undifferentiated. The secretory cell types are classified into two groups, mucous and serous cells. Two types of mucous cells and two to three types of serous cells are distinguished. The salivary glands of the herein studied...

Microescultura da concha de Rectartemon (Rectartemon) depressus (Heynemann) (Gastropoda, Stylomatophora, Streptaxidae) Zoologia
Picoral,Mônica; Lopes-Pitoni,Vera Lúcia.
The microsculpture of Rectartemon depressus (Heynemann, 1868) shell is described on scanning electron microscope. The generics characteristics are proposed: shell's dorsal sculture formed for ribs striae radial; nuclear whorls smooth; ventral surface of the shell smooth or slightly striate; and as specifics characteristics: the number of ribs striae radial on the last world. The R. (R.) depressus presented seven or eight ribs striae radial for millimeter.

Molecular phylogenetics and comparative anatomy of Kimberleytrachia Köhler, 2011 - a genus of land snail endemic to the coastal Kimberley, Western Australia with description of new taxa (Gastropoda, Camaenidae) Naturalis
Criscione, F.; Köhler, F..
Kimberleytrachia Köhler, 2011 is a genus of camaenid land snail endemic to the Western Australian Kimberley region. It comprises twelve previously recognised species, all of which occur within the high precipitation zone along the north-western coast between the Admiralty Gulf and King Sound and within less than about 50 km distance from the coast. By evaluating the variation in shell and genital anatomy as well as the differentiation in the mitochondrial markers 16S and COI, we assess the monophyly of Kimberleytrachia with respect to other camaenid genera from north-western Australia. In addition, we newly describe six species (K. jacksonensis n. sp., K. leopardus n. sp., K. nelsonensis n. sp., K. serrata n. sp., K. setosa n. sp. and K. silvaepluvialis n....

Moluscos de importância econômica no Brasil: II Subulinidae, Subulina octona (Bruguiére) (Mollusca, Gastropoda, Pulmonata, Stylommatophora) Zoologia
Araújo,José Luiz de B.; Bessa,Elizabeth Cristina de A..
A study of the anatomy of Subulina octona, mainly the genital and digestive systems, was undertaken in order to obtain additional data on the taxonomic position in the genus Subulina. The importance of the species as intermediate host for several helminths which occur in Brazil was also discussed.

Moluscos de importância econômica no Brasil: III. Subulinidae, Leptinaria unilamellata (Orbigny) (Mollusca, Gastropoda, Pulmonata, Stylommatophora) Zoologia
Araújo,José Luiz de B.; Keller,Darli Grativol.
An anatomic study of Leptinaria unilamellata (Orbigny, 1835) was made emphasizing the genital system, the pallial chamber the radulae and the mandible. The details of these parts characterize better the species and allow more systematic clarity to the group. The importance of the evolutive cycle of the two trematodes, Postharmostomum gallinum (Witenberg, 1923) and Paratanaisia bragai (Santos, 1934) both parasites of domestic birds in Brazil is accentuated.

Recharacterization of Synapterpes (S.) hanleyi (Pfeiffer) (Mollusca, Gastropoda, Stylommatophora, Subulinidae) Zoologia
Salgado,Norma Campos; Coelho,Arnaldo C. dos Santos.
Synapterpes (S.) hanleyi (Pfeiffer, 1846) is characterized by anatomy, synonymy and geographical distribution. Shell and soft parts were studied and important taxonomic characters evaluated and illustrated. These studies give conditions to characterize the species and include it in the genus Synapterpes Pilsbry, 1896 and distinguish S. hanleyi from the other species of Synapterpes s.s. known only by their shells, respectively from Brazil and Colombia: S.(S.) coronatus (Pfeiffer, 1846) and S.(S.) wallisi (Mousson, 1869).

Simone,Luiz Ricardo L..
A sample of Pulmonata collected in Santa Maria da Vitória, interior of Bahia, Brazil, in Caatinga semi-arid environment, is studied taxonomically. From the five species, four are revealed as new, including a new genus. The new taxa are the Bulimulidae (1) Kora corallina gen. et sp. n. characterized by the elongated shell with aperture somewhat dislocated from the shell axis, and an oblique tooth in middle level of inner lip; (2) Spixia coltrorum, mainly characterized by an uneven spire, delicate sculpture and peristome with 4 equidistant teeth; (3) Anostoma tessa, mainly characterized by a broad spire and well-developed anal canal; and the Megalobulimidae (4) Megalobulimus amandus, mainly characterized by pointed protoconch sculptured by dense quantity of...

Terrestrial gastropods as Fragaria x ananassa pests in southern Brazil: morphological identification Ciência Rural
Landal,Maitê Cristina Tucholski; Bach,Renata Prieto; Gomes,Suzete Rodrigues; Botton,Marcos; Zawadneak,Maria Aparecida Cassilha.
ABSTRACT: Considering the damage caused by terrestrial gastropods in strawberry producing areas in southern Brazil, this study aimed to i) identify the species associated with Fragaria x ananassa in rural properties in municipalities of Paraná State, Brazil; ii) describe and illustrate the diagnostic morphological and conchology features of the mollusk species; iii) construct an illustrated key based on these morphological and conchology features; iv) analyze two species collected in March 2017 to investigate the possible occurrence of parasitic nematodes of medical importance. Taxonomic determination of the mollusks was performed through morphological analysis of samples, and parasitological analysis was carried out using artificial digestion. The...

The genus Bostryx in central western Argentina: anatomical and distributional description of four of its southernmost species (Gastropoda, Bulimulidae) Iheringia, Sér. Zool.
Miranda,María José.
ABSTRACT The genus Bostryx Troschel, 1847 is endemic to South America, extending from Ecuador to Chile and Argentina. The southernmost Argentinian species of the genus that inhabit San Luis, San Juan and Mendoza provinces, specially the pre-Andes, Andes and Sierras Pampeanas mountain ranges, were examined. This is the first time the anatomy of Bostryx pastorei (Holmberg, 1912), Bostryx reedi (Parodiz, 1947) and Bostryx strobeli (Parodiz, 1956) has been described.Bostryx cordillerae (Strobel, 1874) is re-described regarding shell and anatomy due to new morphological data. The main differences among the species examined are based on shell characters. The distribution ofBostryx mendozanus (Strobel, 1874) and Bostryx cuyanus (Pfeiffer, 1867), other species...
