Pairwise COI Sequence Divergence Among Haemaphysalis Tick Species

Pairwise COI sequence divergence among Haemaphysalis species, posted on figshare by K.R. Reshma. The dataset is 9.5 KB in size and was last updated on May 7, 2026. It contains approximate uncorrected pairwise divergence percentages, with categories for intraspecific comparisons and low interspecific divergence.

Use Cases

• Classifying tick species based on genetic divergence thresholds mentioned in the description
• Analyzing geographic patterns of genetic affinity from the sampling location data
• Building phylogenetic models using the pairwise divergence matrix
• Identifying potential cryptic species from low interspecific divergence values (<1%)

Strengths

• Data is focused on a specific genetic marker (COI) for a defined genus (Haemaphysalis), providing taxonomic clarity
• Includes geographic origin metadata for sampling locations
• Released under a permissive CC-BY-4.0 license for reuse

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is very small (9.5 KB), indicating a limited scope
