Introduction
Since the late Triassic, Anatolia witnessed active
geological evolution. Tethys-related land evolution
was partially completed by the late Miocene and by
the Pliocene, evolution of aquatic systems continued. Diversity of the land and aquatic environment
yielded a rich biota in the systems formed. Little of
this rich fauna has been clarified by malacological
studies, which have increased in recent years (Önal
and Kaya 2007, Şengör and Yilmaz 2003).
In hydrobiids, with the addition of the species
described in the presented paper, 46 species are known
from Turkey so far. Most of the genera and species
are, as far as are known, endemic to Anatolia up to
50% (yıldırım et al. 2006). But, the lack of detailed
studies and regional expertise of researchers has resulted in taxonomical problems when comparing the
local fauna to that of Europe. For instance, Paludina
natolica Küster 1852 named as Pseudamnicola natolica (Küster 1852) by Schütt (1965), later Radoman
refused as Pseudorientalia natolica (1973) in the
end of the long years (radoman 1983). After similar studies, the genus Pseudamnicola, reported
to be common throughout Anatolia, was seen to
be restricted to Eastern Anatolia only (Schütt and
Bılgın, 1970, Schütt and ŞeŞen, 1993). Thus further revisions are needed in the group. In this poorly
studied region of Turkey, so far Hydrobiidae genera
Islamia, Sadleriana, Pseudamnicola, Belgrandiella,
Sheitanokok, Hydrobia, Ventrosia, Pyrgorientalia,
Bythinella, Kirelia) were found (Schütt and Bılgın
1970, Schütt and ŞeŞen 1993, yıldırım et al. 2004).
Here, two new genera of Hydrobiidae
(Anadoludamnicola and Sivasi) and two new species (A. gloeri and S. bodoni) and one subspecies (A.
gloeri brevis) are described from Sivas and Malatya.
Identification has been realised by comparing the
anatomy and morphology of the material collected.
Material and Methods
Sampling was quantitative using Ekman grab
(225 cm2). Gastropods were separated from sediNew Genera Anatolidamnicola and Sivasi

Abstract: New freshwater genera (Anadoludamnicola and Sivasi) of Hydrobiidae are described for new hydrobiid
species (Anadoludamnicola gloeri and Sivasi bodoni) from material collected from provinces Sivas and
Malatya (Turkey), using anatomical and morphological data. For now, Sivasi is known from a single locality, while we expect Anadoludamnicola will be found to be commonly distributed in Anatolia.
Key words: Hydrobiidae, Anadoludamnicola, Sivasi, East Anatolia

ment using a system of sieves of different mesh sizes
(20, 2, 1 and 0.5 mm). Gastropods were preserved
in 75% ethanol. Samples were collected from 3 stations with inflatable boat (Fig. 1). between August
2005 and September 2006. Welch’s (1948) method was followed to collect, sift and preserve the
samples. The dissections and measurement of the
genital organs and the shell were carried out using
a stereo microscope (Olympus, SZX12). Totally
82 species have been dissection (22 species belong
to Anadoludamnicola gloeri, 27 species belong to
Sivasi bodoni and 33 species belong to A. gloeri
brevis). The photographs were taken with a digital
camera (Olympus C-5060).

Discussion
In order to determine whether our new
Anadoludamnicola and Sivasi species are new,
we compared them with all other hydrobiid taxa
mentioned in the literature from Central Europe:
Especially Sadleriana species which are similar
(glöer 2002), Turkey: (Schütt and ŞeŞen 1993,
Schütt and BiÝlgıÝn 1970, BiіlgıÝn 1980, Sc 1980)
and other Balkan countries (radoman 1983).
Among the forms in neighbouring areas, the
new genus Anadoludamnicola is most close anatomically to Pseudamnicola. Presence of one recepteculum seminis and an tapering straight penis are the shared characters. This resemblance
marks the relativeness of closely distributed genera. However, Pseudamnicola has black pigmentation in the ovary canal and enlarged oviduct
(radoman 1983), which is not in the new genus.
Also Sadleriana Clessin, 1890 and Pseudorientalia
Radoman, 1973 are similar in penial morphology, but they differ in having two rs instead of one
(glöer 2002 and radoman 1983).
Schütt (1980) described the Pseudamnicola species which have a black ovary canal, however ovary
canal is not black in two new genera in our study.
Considering the other species recorded from the
region, Boettger (1957) described Pseudamnicola
lindbergi from Elbistan (Type locality Elbistan originally reported to be a town in Malatya, but it belongs
to Kahramanmaraş province close to Malatya) using shell characters, but shell characters of the species (olive green coloration and corroded apex) does
not fit with Anadoludamnicola gloeri n. gen. n. sp.
Another aspect to be mentioned is that the presence
of the new genera may indicate that the taxonomical
status of Anatolian ‘Pseudamnicola’ should be reevaluated. At least this study shows the absence of
real Pseudamnicola in the studied area.
Among regional Pseudamnicola species,
Pseudamnicola bilgini described by Schütt and
ŞeŞen (1993) from Amrud spring (Kızıltepe) Mardin
is distinctive with a long bursa copulatrix uncommon
in the genus, but penial characters and the coloration
of the oviduct is similar to that of Pseudamnicola.
Female characters of Pseudamnicola intranodosa
described by Schütt and ŞeŞen (1993) from Düziçi,
Urfa are not known but this species is differentiated

Şahin S., S. Koca, M. Zeki Yildiri
from Anadoludamnicola by a small tubercle on the
inner lip and black oviduct.
Conchologically, Sivasi n.gen is also similar to
Pseudamnicola (ZhadiÝ, 1952). But the male and female genitalia are clearly different: Pseudamnicola
genus has tapering straight penis shape while Sivasi
genus has the penis like bird’s claw. The oviduct
Pseudamnicola’s is not black in Sivasi. Penial shape
is also very characteristic in differentiation from
other similar genera like Anadoludamnicola and
Sadleriana.
Accordingly, both new genera can be differentiated from Pseudamnicola distributed in proximity
of the study area simply by oviduct coloration, shell
characters or penis shape.
The shell dimensions of the new species are
given in Table 1, 2, 3.
In Turkey there have been few survey studies
on Hydrobioidea, but so far 20 genera and 46 species
have been reported to occur in Turkey (YILDIRIM
et al. 2004). Generic and higher systematics in the
fauna is still problematic. The high speciation in the
spring snails is evidently a consequence of narrow
habitat needs and occurrence in places with consistent geographical isolation. Thus we expect further
new species from Turkey.
