Mitogenomes of Two Flea Species for Phylogenetic Analysis

Two complete mitochondrial genomes for the flea species Palaeopsylla remota and Frontopsylla elata elata are sequenced and analyzed. The 7.7 MB dataset includes comparative analyses of nucleotide composition, tRNA structures, codon usage bias, and phylogenetic relationships within Siphonaptera. Author Shaobao Tang published the data under a CC-BY-4.0 license in May 2026.

Use Cases

• Phylogenetic reconstruction of flea families based on mitochondrial protein-coding genes.
• Analysis of codon usage bias and selective pressure in flea mitochondrial genomes.
• Estimation of divergence times for flea lineages, including events post K-Pg boundary.
• Comparative genomics of tRNA secondary structures and non-canonical base pairings in fleas.

Strengths

• First sequencing of mitochondrial genomes for Palaeopsylla remota and Frontopsylla elata elata.
• Comparative analysis includes data from other flea species for broader phylogenetic context.
• Dataset is openly available under a CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in a DOC file format, which may require conversion for computational analysis.
