Aksenova, Olga V., Bespalaya, Yulia V., Bolotov, Ivan N., Kondakov, Alexander V. & Sokolova, Svetlana E., 2016, First molecular identification of Australapatemon burti (Miller, 1923) (Trematoda: Digenea: Strigeidae) from an intermediate host Radix labiata (Rossmaessler) (Gastropoda: Lymnaeidae) in Europe, Zootaxa 4132 (4), pp. 588-590 : 588-589

Australapatemon burti ( Miller, 1923)

Parasitic stage. cercaria (ITS2 sequence: NCBI’s Genbank acc. no. KU950451 ).

Host. Radix labiata (Rossmaessler) (voucher no. MLym- 116 in RMBH; COI sequence: NCBI’s Genbank acc. no. KU950449 ).

Location. Slovakia: Low Tatras, near Vihodna, 49°03'07" N, 19°54'56" E, 740 m alt., trout pond, 10.vii.2013, S. Sokolova leg.

Remarks. Accordance between our ITS2 sequence of A. burti cercaria from Slovakia and the sequence of adult fluke from a Mexican duck specimen is 100% ( Figure 1 ). According to recent works, Lymnaea stagnalis (Linnaeus) , Stagnicola palustris (Müller) , Radix auricularia (Linnaeus) , Radix peregra (Müller) , Radix ovata (Draparnaud) and Bathyomphalus contortus (Linnaeus) are listed as host snail taxa for A. burti in Europe ( Faltýnková et al. 2007, 2016; Soldánová et al. 2012). However, R. peregra and R. ovata are invalid nominal taxa ( Schniebs et al. 2013, 2015). The snail specimens, which were identified under these names, may actually belong to at least four different but relatively morphologically similar biological species: R. labiata , Radix ampla (Hartmann) , Radix lagotis (Schrank) and Radix balthica (Linnaeus) ( Schniebs et al. 2013, 2015). Here we confirmed that R. labiata is a host of A. burti cercariae in Europe using the molecular approach to both the parasite and the host for the first time.
