Maximum likelihood (ML) trees of studied Fridericia species based on the ITS region (A), CO1 (B) and H3 genes (C). Bootstrap values greater than 50 are shown at the nodes. Sequences from new species described here appear in bold. A ML tree of the ITS region based on 634 nucleotide positions using the K2+G+I substitution model B ML tree of the CO1 gene based on 455 nucleotide positions using the T93+G substitution model C ML tree of the H3 gene based on 145 nucleotide positions using the K2+G substitution model. Scale bars: 0.1 substitutions per nucleotide position, except H3 gene 0.05.
