“…Large numerous deep punctuations are distributed on the lateral sides of the scutum in A. americanum (Vasil’eva, 2011 ) but A. geoemydae possesses few punctuations on scutum followed by little more punctuations scattered over alloscutum. Amblyomma longirostre (Ogrzewalska et al 2010 ) , A. testudinarium, A. sculptum (Suzin et al 2022 ), and A. marmoreum display relatively short cervical groove length although cervical field depression is apparent in A. sculptum and non-apparent in A. geoemydae and A. longirostre (Luz et al 2017 ). Eyes are flat and slightly convex in A. naponense (Szabó et al 2007 ) , A. brasiliense and A. geoemydae however, differ in the number and width of festoon grooves.…”

Animal ectoparasites are linked to the spread of serious medical and veterinary important pathogens. Our research intends to close the knowledge gap concerning the numerous ectoparasites that inhabit animals in Wayanad. Ectoparasites in animals brought to the veterinary dispensaries in Wayanad were retrieved and identified morphologically and molecularly. Using a high-quality stereomicroscope, the taxonomic features of the four following species were examined and identified : Haemaphysalis bispinosa , Rhipicephalus annulatus, R. microplus , and Amblyomma geoemydae . The important disease vector A. geoemydae was reported for the first time in Kerala. The important phenotypic characters of the highlighted species A. geoemydae are the edge of the basis capituli is circular without cornua, and the hypostomal dental formula is 2/2. The taxonomically identified four species were subjected to CO1 gene sequence analysis. The evolutionary relationship was inspected through the neighbour-joining method, and the phylogenetic tree was built through the Maximum Likelihood method . The present study has also estimated the diversity index of R. microplus , R. annulatus , H. bispinosa , and A. geoemydae . Among them, R. microplus 0.36638 have reported with the maximum diversity index score. The significance of the study is the presence of Lyme disease vector A. geoemydae , in the Wayanad District of Kerala, and it is the first report of the species from where an outbreak of Lyme disease occurred in 2013.
