(Mycetopodidae, Iridinidae)))))). A consensus arrangement of several provincial, species-level
treatments yields fewer than 850 recognized, valid species worldwide, with all but 5-6 belonging to
the Unionoida. We regard this as an under-estimate. While there are, no doubt, more species to be
described, thorough taxonomic revisions are hindered by the ca. 4900 available species-group level
nomina. We will discuss patterns of regional and taxonomic diversity and highlight the value of the
MUSSEL Project Database for synthetic and revisionary studies of the Palaeoheterodonta.

This work is based on a systematic and taxonomic description of different species of terrestrial and
fluvial molluscs. It was developed in three natural zones in the Amazon region of Peru. The
collection took place between February and April 2001. The studied areas are located as following:
(1) In the Alto Mayo Forest-BAM 06˚13΄04˝S 76˚54΄55˝ W, in the San Martín department in
Northwest Peru; (2) Tingo María National Park-PNTM 09˚19΄45˝S 76˚01΄39˝ W, Huánuco
department in Northeast Peru; (3) Manu National Park PNM 13˚09΄43˝S 71˚35΄39˝ W, Madre de
Dios department in Southeast Peru. The recent gastropod fauna located in the referred study sites is
described and documented, corresponding to 5.000 individuals of different families. The identified
individuals were catalogued in a database covering 787 samples. Each sample was numbered and
identified following the guidelines of the Zoological Museum of Hamburg (ZMH) Germany. The
systematic and taxonomic list of the species was classified into 25 superfamilies, 40 families, 63
genera and 136 species. According to these results the superfamilies Helicinoidea and the
Orthalicoidea have been investigated in detail and subsequently split in 3 families. 11 species of the
family Helicinidae and 3 species of the family Ceresidae were assigned to the first superfamily, 9
species of the genus Drymaeus belonging to the family Bulimulidae (=Orthalicidae) were assigned to
the second superfamily. These three families are documented by a total of 400 specimens. Within the
family Helicinidae Lamarck, 1799, the following new species (sp.nov) were tentatively classified:
Helicina bandeli sp.nov; Helicina peruensis sp.nov; and Alcadia kasteli sp.nov. The genus
Archacharax and species blandianus, glaeserius and cousini, belonging to the family Ceresidae
Thompson, 1980, have been redescribed. Field data and bibliography were also collected for each
species. Morphology and distribution are discussed and commented. Photographs show different
shell forms of each species separated for each location.
