On altitude dependent characters in Albinaria idaea (L. Pfeiffer, 1849), with a revision of the species (Gastropoda Pulmonata: Clausiliidae)
Provedor de dados: 16
Autores: Engelhard, G.H.; Slik, J.W.F.
Several forms of Albinaria idaea (L. Pfeiffer, 1849) have been described as (sub)species from various sites on Mt. Ida (Central Crete). In recent years, however, much additional material has been collected, which made clear that no sharp boundaries exist between these forms. Moreover, several characters proved to be altitude dependent to a certain extent. It may be concluded that on Mt. Ida only a single evolutionary entity can be distinguished, viz. A. i. idaea. On the isolated Mt. Kedros, south-west of Mt. Ida, an undescribed allopatric form was found, which because of its smaller size and differences in altitude dependent characters was given subspecific rank as A. i. amabilis ssp. nov. On the Paximadia Isles, south of Central Crete, a percostate and a...

The anatomy and phylogeny of the African land snail Limicena Connolly, 1925 (Pulmonata: Cerastidae)
Provedor de dados: 16
Autores: Mordan, P.
An investigation of the anatomy of Limicena confirms its position as a monotypic genus in the Cerastidae. Phylogenetic analysis places Limicena as the most plesiomorphic member of a clade characterised by a pseudosigmurethrous excretory system, the more advanced members of which are Rhachistia, Amimopina and Edouardia. Its position at the base of such a widely dispersed, advanced clade with apparently xerophilic adaptations lends support to a dispersalist hypothesis for the extra-Afrotropical distribution of the Cerastidae.

The Arion Hortensis complex (Pulmonata: Arionidae): designation of types, descriptions, and destributional patterns, with special reference to the Netherlands
Provedor de dados: 16
Autores: Winter, A.J. de.
A lectotype of Arion hortensis Férussac, 1819 and a neotype of A. distinctus Mabille, 1868 are selected in order to assure nomenclatural stability. Descriptions of preserved specimens of these species from large parts of central and western Europe are provided, as well as of living animals from The Netherlands and Belgium. The main characters used by Davies (1977, 1979) to separate the British representatives of this complex were found suitable in the rest of Europe as well, in contrast to some characters given by De Wilde (1983). Arion owenii Davies, 1979 was not present in the material studied. Provisional UTM-distribution maps (50 km grid) of A. hortensis and A. distinctus in Europe (except the British Isles and Belgium) are provided, besides 10 km grid...

Comparative reproductive anatomy in the South African giant land snails (Gastropoda: Pulmonata: Achatinidae)
Provedor de dados: 16
Autores: Mead, A.R.
The history and current taxonomic status of 62 nominal taxa are revised that have been associated in the literature with the subgenus Tholachatina Bequaert, 1950, of genus Archachatina Albers, 1850, and the genus Cochlitoma Férussac, 1821, in the land snail family Achatinidae Swainson, 1840. Tangible, reliable characters have been found in the detailed features of the reproductive anatomy in this family. The results of comparative anatomical study convincingly reflect phylogeny in contrast to the comparative study of only the shell characters. This latter more strongly reflects the effects of the intrinsically variable environment over time. In the present study, both sets of characters are needed to refine identification.  Change, and therefore...

Streptaxidae (Mollusca: Gastropoda: Pulmonata) of the Seychelles Islands, Western Indian Ocean
Provedor de dados: 16
Autores: Gerlach, J.; Bruggen, A.C. van.
The taxonomy of the species of the terrestrial carnivorous snail family Streptaxidae of the Seychelles archipelago is reviewed with the exception of the three species of the genus Priodiscus (vide Gerlach, 1995). All 18 species are restricted to the northern, granitic islands. This paper describes 15 species, including two new genera (Silhouettia and Careoradula), and four new subspecies (Edentulina dussumieri reservae, E. d. silhouettae, E. d. praslina, Stereostele nevilli parvidentata). The nominal taxon Streptaxis (Imperturbatia) constans var. silhouettae is raised to species level to become the type species of the new genus Silhouettia.

Revisionary notes on Negulus O. Boettger, 1889, a genus of minute African land snails (Gastropoda Pulmonata: Vertiginidae)
Provedor de dados: 16
Autores: Bruggen, A.C. van.
The genus Negulus is reviewed; only four Recent species, restricted to continental Africa, are recognized. The genus is extinct in Europe, being only recorded from Tertiary deposits. A key to the shells of the Recent species (all figured) is supplied. The anatomy is as yet unknown. A sinistral shell of N. abyssinicus is described from among a series of paralectotypes in the Leiden Museum, the first such abnormality in the genus (figured). A fair amount of shell material has become available (among which some historical specimens) so that metric data may be compared with greater confidence. Recent occurrence is established/confirmed for Eritrea, Ethiopia, Sudan, Kenya, Tanzania, Zaire, Zambia, Malaŵi, and Bioko (Fernando Poo). The small size of the shell...

On the only Greek Sphincterochila species, two Libyan close relatives, Cerigottella subgen. nov., and an extended diagnosis of the Sphincterochilidae (Mollusca, Gastropoda Pulmonata)
Provedor de dados: 16
Autores: Gittenberger, E.
From Greece, based on conchological characters, a single, endemic Sphincterochila species has been reported about a century ago. Its occurrence is still thought to be restricted to the islet of Andikithira. The structure of the genitalia, hitherto unknown, demonstrates that it concerns a separate species indeed; its closest relatives known are two Libyan species. These three species differ from the Sphincterochila species studied so far most clearly by the stimulatory organ, inserting not on the genital atrium but far more distally on the vagina. They are classified within Cerigottella subgen. nov.

Provedor de dados: 16
Autores: Bruggen, A.C. van; Winter, A.J. de.
‘Marconia’ hamiltoni s.l. is known from two discrete mountainous areas in Malawi, i.e. the (southern) Mt. Mulanje complex, and the (more northern) Zomba Plateau s.l. These uplands are separated by about 65 km of lower lying land with different types of vegetation and climate. Material from these two regions may be distinguished as separate species, the southern populations having comparatively small and broad shells with some apertural dentition (‘M’. hamiltoni, lectotype designated), while the northern populations have noticeably larger and more slender shells with a more reduced apertural dentition (‘M’. malavensis). Discussion of the type localities for both taxa shows that these are either localized in an unlikely place (‘M’. hamiltoni) or unclear...

Provedor de dados: 16
Autores: Bruggen, A.C. van.
Gulella adami spec. nov. is described from a classical West African locality, Assini in the Ivory Coast (Côte d'Ivoire). It is most unusual in showing two superficial parietal processes, which may also be interpreted as a double angular lamella, in the aperture of the shell. The shell closely resembles that of various Enidae in SE Europe and adjoining areas around the Mediterranean, thereby providing a striking example of convergent evolution.

Autores: Schilthuizen, M.; Welter-Schultes, F.W.; Wiese, V.
On the basis of both detailed distributional field studies and morphological analyses, a revision of the polytypic species Albinaria hippolyti from Central and Eastern Crete is presented. True subspecies are distinguished from mere geographic varieties by the presence of narrow hybrid zones. Using this criterion, four adjoining subspecies are recognised: A. h. hippolyti (Boettger, 1878), A. h. aphrodite (Boettger, 1883), A. h. holtzi (Sturany, 1904) and A. h. harmonia subspec. nov. Additionally, two geographically isolated and conchologically distinctive forms are also treated as subspecies: A. h. arthuriana (Boettger, 1878) and A. h. asterousea subspec. nov. The geographical distribution and variability of each subspecies is described in detail. A. h....

Our knowledge concerning taxonomy and zoogeography of the fossil and recent species of the helicid genus Theba is summarized and enlarged. The fossil T. arinagae spec. nov. is described from Gran Canaria. The recent T. andalusica spec. nov. and T. sacchii spec. nov. are described from the southernmost part of the Iberian peninsula and the southernmost part of Morocco, respectively. This implies that four fossil and ten recent Theba species are recognized. Two of the fossil species are very insufficiently known. Some recent species are polytypic, which results in 17 (sub)specific taxa in total. Neotypes are selected for T. subdentata legionaria and T. solimae.

Provedor de dados: 16
Autores: Bruggen, A.C. van; Winter, A.J. de.
Micractaeon kakamegaensis Verdcourt, 1993 (type loc. Kenya, Kakamega Forest), is a synonym of Pseudopeas koptawelilense Germain, 1934 (type loc. Kenya, Mt. Elgon); the proper name is therefore Micractaeon koptawelilensis (Germain, 1934). New anatomical data are supplied, more or less confirming classification in the family Ferussaciidae. The shell is subject to some considerable variation in size, shape and sculpture. The species appears to be widely distributed in various types of forest in tropical Africa (Ghana, Cameroon, eastern and south-eastern Zaïre, Kenya, Malawi, and eastern Zambia); hypsometrical distribution is generally from c. 950 m to c. 2300 m, although in Ghana it has been collected at altitudes of between &amp;lt; 250 and c. 700 m.

Minaselates, a new genus and new species of Epiphragmophoridae from Brazil (Gastropoda: Stylommatophora: Helicoidea)
Provedor de dados: 103
Autores: Cuezzo,Maria Gabriela; Pena,Meire Silva.
ABSTRACT We describe a new genus and a new species in the family Epiphragmophoridae, Minaselates paradoxa sp. n. The new species was found at the National Park Cavernas do Peruaçu, in northern portion of the state of Minas Gerais, Brazil. Minaselates paradoxa sp. n. is classified in Epiphragmophoridae based on the fact that it shares the following diagnostic features of the family: a dart apparatus with a single dart sac, and two unequal mucous glands at the terminal genitalia. Minaselates gen. n. differs from Epiphragmophora Doering, 1874 by having a granulose protoconch, shell spire with blunt apex, complex microsculpture on the teleoconch and closed umbilicus fused with the shell wall. Also, significant differences between the two genera are the...

The study of 41 individually specimes of Subulina octona (Bruguiére. 1789) during 182 days indicated that oviposition occur between 10pm and 10am. The interval between ovipositions was from seven to 31 days. In the eggs, the greatest axis was 1.5-2.0mm while the smallest was 1.2-1.6mm. The lenght of shell of recently ecloded snails was 1.3-1.8mm. The growth rale of adult snails was measured and they grew more in the first 45 days than in the last 75 days subsequent of the study.

Moluscos de importância econômica no Brasil: III. Subulinidae, Leptinaria unilamellata (Orbigny) (Mollusca, Gastropoda, Pulmonata, Stylommatophora)
Provedor de dados: 104
Autores: 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.
