The genus Theobald, 1904 (Diptera: Culicidae) comprises 36 wild mosquito species, with distribution largely restricted to tropical and temperate areas, most of which are not recognized as vectors of epidemiological importance due to the lack of information related to their bionomy and involvement in the cycle transmission of infectious agents. Furthermore, their evolutionary relationships are not completely understood, reflecting the scarcity of genetic information about the genus. Therefore, in this study, we report the first complete description of the mitochondrial genome of a Neotropical species representing the genus, Coquillet, 1906, collected in the Brazilian Amazon region.

The genus has 817 species subdivided into 28 subgenera. It has a cosmopolitan distribution, being most abundant in countries with a tropical climate. Understanding the ecology and diversity of viruses circulating in the species of this genus is important for understanding their role as arbovirus vectors in Brazil.

The genus Limatus (Diptera: Culicidae) are wild mosquitoes belonging to the Sabethini tribe that occurs in tropical countries and is related to transmission cycles of Orthobunyavirus (Bunyaviridae), particularly in the Amazon region. Given the unavailability of information related to evolutionary biology and molecular taxonomy aspects of this genus, we report here the first complete sequencing of the mitochondrial genome of Limatus durhamii Theobald, 1901. The NextSeq 500 platform was used for sample sequencing, and the mitochondrial sequence obtained was 14,875 bp long, comprising 37 functional subunits (13 PCGs, 22 tRNA and 02 rRNA).

The genus Aedes (Diptera: Culicidae) includes species of great epidemiological relevance, particularly involved in transmission cycles of leading arboviruses in the Brazilian Amazon region, such as the Zika virus (ZIKV), Dengue virus (DENV), Yellow fever virus (YFV), and Chikungunya virus (CHIKV). We report here the first putatively complete sequencing of the mitochondrial genomes of Brazilian populations of the species Aedes albopictus, Aedes scapularis and Aedes serratus. The sequences obtained showed an average length of 14,947 bp, comprising 37 functional subunits, typical in animal mitochondria (13 PCGs, 22 tRNA, and 2 rRNA).

Article Synopsis
  • The Culicidae family, which includes approximately 3,587 species, is divided into two subfamilies: Anophelinae and Culicinae.
  • Researchers have analyzed complete mitochondrial DNA sequences from several species, revealing an average length of 15,046 base pairs with 78.02% AT content, and identifying 37 functional components including protein coding genes and tRNAs.
  • Phylogenetic analyses using 48 mitogenomes support current taxonomic classifications, confirming the monophyly of the groups studied and revealing some unexpected relationships among certain genera within the Culicinae subfamily.
