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 < 250 and c. 700 m. |

In this publication a revision is given of the genera of the subfamily Bulimulinae (Gastropoda, Pulmonata, Bulimulidae). The morphological variation of the shell, radula, pallial organs and genitalia is analized and 21 character transition series are recognized. In the systematical part the following data are presented for each genus : description of shell and anatomy, distribution, ecology, bibliography and a list of taxa. The number of (sub) genera is reduced from 80 to 43 ( + two nomina inquirenda). A new synonymy is : Paracochlea Hylton Scott, 1967 = Eudioptus Albers, 1860. The following new species names are introduced : Bostryx sophieae, Drymaeus (Drymaeus) marcapatensis, Drymaeus (Drymaeus) sophieae, Drymaeus (Mesembrinus) pseudobesus. Berendtia... |

Our knowledge concerning the recent and fossil species and subspecies of the Aciculidae is summarized. After some introductionary chapters concerning habitat, anatomy, shell morphology and distribution, both in time and geographical, all taxa are dealt with systematically. In total 56 recent species of Aciculidae are characterized, belonging to Acicula (20), Menkia (1), Platyla (25) and Renea (10). In addition 15 fossil species are recognized, in Acicula (5), Menkia (1), Platyla (6) and Renea (3). Four Acicula species and one Platyla species are known from the Miocene to the Recent. Keys enable the identification down to the subspecies level. Synonymy lists are given. The species and subspecies are described and illustrated. Distributional data are... |

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... |

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. The nominate subspecies of T. pisana is shown to be aberrant because of its very wide range; the... |

Gulella annibiodiversitatis spec. nov. is described from a few scattered localities in montane forest above c. 1300 m in southern-central Malaŵi. It is mainly characterized by a smallish (4.9-6.3 mm high), smooth and generally featureless shell without apertural dentition. Gulella menkhorsti spec. nov., has a small (2.3-2.9 mm high) and smooth shell with a six-fold dentition and is probably a restricted range endemic; so far it has only been recorded from the Mpita Forest in southern Malaŵi. A single smooth and small shell (2.7 mm) with a seven-fold apertural dentition from the Misuku Hills in northern Malaŵi also does represent a new species, Gulella crux spec. nov. Another sample from the same area, introduced as Gulella nuchalis spec. nov., has a... |

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... |
