All the taxa of genus and species groups introduced for the European valvat
iform hydrobiids are analyzed, and if possible revised.
All the type species have been redescribed on the basis of new anatomical s
tudies or data in the literature when spirit specimens were not available.
This enabled the following taxa. to be recognized as junior synonyms of Hau
ffenia Pollonera, 1898 (type species Horatia (Hauffenia) tellinii Pollonera
, 1898): Erythropomatiana Radoman, 1978 (type species Valvata erythropomati
a Hauffen, 1856); Lobaunia Haase, 1993 (type species: Lobaunia danubialis H
aase, 1993); Neohoratia Schutt, 1961 (type species Valvata (?) subpiscinali
s Kuscer, 1932); and Vrania Radoman, 1978 (type species Valvata wagneri Kus
Of the species currently assigned to Hauffenia, only a few from the eastern
Alps and Balkans actually belong to it: H. erythropomatia (Hauffen, 1856);
H. kerschneri (Zimmermann, 1930); H. media Bole, 1961; H. subcarinata Bole
& Velkovrh, 1987; H. subpiscinalis ( Kuscer, 1932); H. tellinii (Pollonera
, 1898) (with H. michleri Kuscer, 1932, as junior synonym); H. tovunica Rad
oman, 1978; H. wagneri (Kuscer, 1928); and H. wienerwaldensis Haase, 1992.
Each is redescribed.
Many "Hauffenia" species from the Balkans remain of uncertain generic statu
s due to the absence, or incompleteness of anatomical data. However, Horati
a (Hauffenia) raehlei Schutt, 1980, is placed in the genus Fissuria Boeters
, 1981, on the basis of its anatomy.
After anatomical study, most of the French "Hauffenia" have been assigned t
o Islamla Radoman, 1973a, and tentatively to the following species: I. minu
ta (Draparnaud, 1805), I. globulina (Paladilhe, 1866), I. spirata (Bernasco
ni, 1985), and I. consolationis (Bernasconi, 1985). Anatomical study of the
French "Horatia" exilis (Paladilhe, 1867) supports its allocation to a new
genus: Heraultia, n. gen.
The Spanish species currently assigned to "Horatia" or "Neohoratia" do not
belong to these genera. Some of them, namely "N." ateni (Boeters, 1969), "N
." globulus globulus (Bofill, 1909), and "N." g. Iagari (Altimira, 1960), b
elong to Islamia.
Diagnoses and keys are provided for the European valvatiform hydrobiid gene
ra and for the species of Hauffenia, together with tables summarising their
taxonomic status and distribution.
