Description of Male, Redescription of Female, Host Record, and Phylogenetic Position of Haemaphysalis danieli

Haemaphysalis ticks are globally distributed with the greatest diversity in the Oriental region. This study aimed to primarily provide information on the morphology, host record, and preliminary phylogenetic position of a poorly known tick Haemaphysalis danieli. Herds comprised of goats and sheep were examined for this tick species in Upper Dir, Khyber Pakhtunkhwa, Pakistan. A total of 127 ticks, including males (n = 15, 11.8%) and females (n = 112, 88.2%), were collected, and morphologically identified as H. danieli. The morphological identification was confirmed through the 16S rDNA and cytochrome c oxidase (cox1) sequences. Phylogenetic analysis inferred based on 16S rDNA and cox1 showed a close evolutionary relationship of H. danieli with a conspecific from China and an undetermined Haemaphysalis sp. from China and Anatolia. A total of 32/223 (14.3%) goats in two different herds were the only host infested by H. danieli. The earliest study provided the morphological description of H. danieli male, host record, and phylogenetic position. The information provided herein could assist in minimizing the knowledge gap regarding the systematic and taxonomy of Haemaphysalis species.

Automated summary

This study investigated the poorly known tick Haemaphysalis danieli in Pakistan, confirming its morphology, host record, and phylogenetic position in relation to other Haemaphysalis species. The study found a close evolutionary relationship between H. danieli and a conspecific from China, as well as an undetermined Haemaphysalis sp. from China and Anatolia.
