From: DNA sequence characterisation and phylogeography of Lymnaea cousini and related species, vectors of fascioliasis in northern Andean countries, with description of L. meridensis n. sp. (Gastropoda: Lymnaeidae)

Figure 2

Nucleotide differences in a total of 62 variable positions found in the complete 18S rDNA sequence of the lymnaeid species compared and their location in the secondary structure. Helix, Position and Difference number = numbers to be read in vertical. Position = numbers refer to positions obtained in the alignment made with MEGA 4.0. Identical = .; Indel = -. Bold text corresponds to helix E10-1 of the variable area V2 where differences in the 18S rRNA gene of Lymnaeidae are concentrated [46]. Accession Nos. = [EMBL: Z73980-Z73985] [46]; [EMBL: Z83831] [47]; [EMBL: AM4122222] [42]; L. cousini and P. columella from present study. Sequence correspondences: * L. cubensis, L. viatrix and L. cousini without definitive genus ascription; ** 18S identical in L. viatrix and L. neotropica [42]; *** 18S identical in P. columella and L. ubaquensis (present paper); **** 18S identical in L. cousini from Ecuador, L. bogotensis and L. meridensis n. sp. (= L. cousini from Laguna Mucubaji, Venezuela) (present study)
