The taxonomy of ticks of the subgenus Boophilus has been extensively debated and is often complicated by the high intraspecific variation of morphological features between species. Notably, the cattle tick Rhipicephalus microplus is a species complex consisting of Rhipicephalus annulatus, Rhipicephalus australis and the three mitochondrial clades (A-C) of R. microplus. To gain insight into the taxonomic status of this species complex, we performed morphological and molecular analyses on these cattle ticks across four states in peninsular Malaysia. We morphologically identified 60 males and 104 females of R. microplus, 298 males and 374 females of R. australis, and one R. annulatus male in our field collection, of which the latter two species have never been recorded in Malaysia. However, all three morphologically identified species were molecularly assigned as R. microplus clade A based on the barcoding cytochrome oxidase subunit I (COI) analysis. The discrepancy between morphological and genetic data highlights an urgent need for further exploration and in-depth research into the taxonomic status of these sympatric tick species.
