Culex australicus is an indigenous mosquito species endemic to Australia and parts of the Pacific, including New Caledonia. It is a member of the Culex pipiens species complex, which also includes Culex quinquefasciatus and Culex globocoxitus. This species is of interest due to its ecological role and evolutionary significance.
Culex australicus is found throughout Australia, particularly in temperate and subtropical regions. It has also been recorded in New Caledonia, with unconfirmed reports from Vanuatu.
Genetic studies have shown that Culex australicus and Culex globocoxitus form a monophyletic group within the Culex pipiens complex. These species are genetically distinct and are most closely related to the cosmopolitan Culex quinquefasciatus. This suggests that Culex australicus diverged from Culex quinquefasciatus after its colonization of Australia.
While Culex australicus is not a primary vector for human diseases, it plays a significant role in the ecosystem. It has been identified as a vector for the rabbit virus myxomatosis, which has important implications for wildlife management.
Identification of Culex australicus larvae can be made using the following characteristics:
Siphon Index: The ratio of the length to the width of the siphon is greater than 5:1.
Siphon Shape: The basal third of the siphon is not swollen.
Antennae: Larvae have long antennae.
These features differentiate Culex australicus from other species like Culex quinquefasciatus, which has a swollen basal third of the siphon.
