Insights from entire mitochondrial genome sequences into the phylogeny of ticks of the genera Haemaphysalis and Archaeocroton with the elevation of the subgenus Alloceraea Schulze, 1919 back to the status of a genus

open access: yesMedical and Veterinary Entomology, Volume 38, Issue 2, Page 189-204, June 2024.
We sequenced the entire mt genomes of three species of tick for the first time: Bothriocroton auruginans, B. hydrosauri and H. (Kaiseriana) novaeguineae, and we sequenced the 18S rRNA gene of B. hydrosauri and H. (Kaiseriana) bancrofti. In our phylogenetic trees, Alloceraea was the sister to Archaeocroton sphenodonti, from New Zealand; to the exclusion
