![]() tritaeniorhynchus in Australia is a concern to health officials as the species is an important vector of JEV and is now the sixth species from the subgenus Culex capable of vectoring JEV in Australia. The vector is likely to be already established in northern Australia, given the wide geographical spread throughout the Top End of the NT. tritaeniorhynchus in Australia from the Darwin and Katherine regions of the NT. tritaeniorhynchus from other members of the Vishnui subgroup from the NT. Useful diagnostic morphological characters were identified and are presented in a taxonomic key to adult females to separate Cx. We provide COI barcodes for most NT species from the Vishnui subgroup to aid future identifications, including the first genetic sequences for Culex ( Culex) crinicauda and the undescribed species Culex ( Culex) sp. ![]() tritaeniorhynchus from Southeast Asia and the Middle East. The phylogenetic analysis showed that the NT specimens formed a monophyletic clade with other Cx. tritaeniorhynchus from Dili, Timor-Leste. Sequence percentage analysis of COI revealed that specimens from the NT shared 99.7% nucleotide identity to a haplotype of Cx. Once identified using COI, specimens were reanalysed for diagnostic morphological characters to inform a new taxonomic key to related species from the NT. Molecular identification was performed using cytochrome c oxidase subunit 1 (COI) barcoding, including sequence percentage identity using BLAST and tree-based identification using maximum likelihood analysis in the IQ-TREE software package. Specimens were preliminarily identified morphologically as the Vishnui subgroup in subgenus Culex. tritaeniorhynchus female specimens ( nā=ā19) from the Darwin and Katherine regions. In February and May, 2020 the Medical Entomology unit of the Northern Territory (NT) Top End Health Service collected Cx. The mosquito species is widely distributed throughout Southeast Asia, Africa and Europe, and thought to be absent in Australia. Culex ( Culex) tritaeniorhynchus is an important vector of Japanese encephalitis virus (JEV) affecting feral pigs, native mammals and humans.
