Phylogenetic analysis of shared 3' LWS P180 sequence. A neighbour-joining bootstrap consensus tree of a 243 base pair portion of 3' LWS S180 and LWS P180 opsins from J. onca and relatives. The percentage of trees in which the associated taxa clustered together in the bootstrap test (500 replicates) is reported at the nodes. The Jukes-Cantor algorithm was used and all codon positions were included . Pair-wise deletion was used in the case of missing nucleotides for the analysis. Phylogenetic analyses used MEGA4  [accession numbers see Additional file 3].
