Malacological news from the Czech and Slovak Republics in 2015–2019

Abstract

Since the last comprehensive overview of the Czech and Slovak mollusc fauna, released in 2013, several records of species new for the countries or particular regions have appeared. In this paper, we summarize all such records and news collected in 2015–2019, including those affecting nomenclature and the national Check-lists made in 2013 and 2014. The rules for the selection of the records are: (i) the first record in Bohemia, Moravia or Slovakia, (ii) regionally important new records, (iii) records of species listed in NATURA 2000 and the national Red-lists as either critically endangered or endangered species, and (iv) currently spreading non-native species. New records are briefly commented and summarized for each species separately. Location data are published with all details in a supplementary table and are freely accessible.

Next step in Monacha cantiana (Montagu, 1803) phylogeography: northern French and Dutch populations (Eupulmonata, Stylommatophora, Hygromiidae)

“…Our previous research on several M. cantiana populations, using an integrative approach combining analysis of the shell structure and genital anatomy with that of nucleotide sequences of mitochondrial and nuclear gene fragments, revealed six lineages, namely CAN-1, CAN-2, CAN-3, CAN-4, CAN-5 and CAN-6 ( Pieńkowska et al 2018b , 2019a ). CAN-1 (representing true M. cantiana ) was found to occur in the Latium region of Italy and in Spain and Britain ( Pieńkowska et al 2018b ; Čejka et al 2020 ), in line with the suggestion that this lineage probably spread with the Roman conquests ( Pieńkowska et al 2018b ). Populations of CAN-2 were found in regions of Italy (Emilia Romagna) north of Latium ( Pieńkowska et al 2018b ) and somewhat surprisingly in Slovakia (Bratislava) ( Čejka et al 2022 ), while those of CAN-3 were reportedly widespread even further north in Italy (Friuli-Venezia Giulia) as far as Vienna in Austria ( Pieńkowska et al 2018b , 2019b ) and Bratislava in Slovakia ( Čejka et al 2022 ).…”

“…Sequences deposited in GenBank for M. cantiana s.l. from other populations ( Manganelli et al 2005 ; Duda et al 2011 ; Kruckenhauser et al 2014 ; Cadahia et al 2014 ; Pieńkowska et al 2015 , 2018b , 2019a , 2019b ; Razkin et al 2015 ; Neiber and Hausdorf 2017 ; Čejka et al 2020 , 2022 ) and three other Monacha species ( M. cartusiana : Pieńkowska et al 2015 , 2022 ; Neiber and Hausdorf 2017 ; Caro et al 2019 ; Čejka et al 2020 ; M. pantanellii (De Stefani, 1879): Pieńkowska et al 2020 ; M. parumcincta (Rossmässler, 1834): Pieńkowska et al 2018b ) were also selected for molecular analysis (Suppl. materials 1 – 4 ) and supplemented with several new sequences of mitochondrial ( 16SrDNA ) and nuclear ( ITS2 flanked with 5.8SrDNA and 28SrDNA) genes (Table 1 ).…”

The lineage CAN-4, corresponding to Monacha cemenelea (Risso, 1826), was found in south-eastern France ( Pieńkowska et al 2018b ; Čejka et al 2020 ). CAN-5 and CAN-6 are reported from the Apuan Alps and represent one or two different species, the naming of which requires further studies on topotypical material ( Pieńkowska et al 2019a ).…”
