• •High levels of genetic diversity at the COI gene suggest the presence of cryptic species within Anopheles tessellatus.•Species delimitation approaches (ABGD, mPTP and RESL) support up to six putative species, some of which are important vectors of human disease.•These findings have potentially important consequences for vector management and disease control. Anopheles tessellatus is a potentially important vector found across South, East and Southeast Asia. While it was formerly considered a formidable vector of human Plasmodium and filarial parasites in the Maldives, and of lesser importance as a vector of human Plasmodium in Sri Lanka and parts of Indonesia, it is currently of little or unknown health importance in many other parts of its range. This study describes the genetic diversity and evolutionary relationships among An. tessellatus populations in nine Asian countries at the COI gene using maximum-likelihood and Bayesian phylogenetic inference tree and cluster-based species delimitation approaches. These analyses reveal exceptional levels of genetic diversity in An. tessellatus populations across its known range, and identify up to six putative species in the newly determined Tessellatus Complex. The existence of such cryptic diversity has potentially important consequences for vector management and disease control. Differences in the ecologies and life histories among these species may have considerable impact on vectorial capacity and may go some way towards explaining why An. tessellatus s.l. has such varying degrees of public health importance across its range.
