Anophelinae is a widely dispersed Culicidae subfamily that may carry a unique virome. Here we herein report the set of viruses found in 323 salivary glands of 16 anopheline species sampled at Upper Pantanal, Chapada dos Guimarães National Park and Coxipó river basin, South Central Mato Grosso, Brazil, pooled (n = 11) and subjected to high throughput sequencing. Metagenomics revealed the presence of nine viral sequences belonging to novel viruses from seven viral families: Purunga is a putative novel orbivirus sharing 74% and 65% aa identity, respectively, with the VP1 and VP3 segments of Changuinola serogroup, Jaracatiá flavivirus shares 60% amino-acid (aa) identity with Aedes flavivirus. Coxipó dielmovirus and Chapada dielmovirus shared 51% and 39% aa identity with Merida virus. Coloiado-orthomyxo like virus is 57.1-64.8% identical at aa level to Aedes albonnulatus orthomyxo-like virus. Mujica picorna-like virus shares 49% aa identity with Flen picorna-like virus and Chiquitos virus is 50% similar to Ista virus, both from Picornavirales order. Cerrado partiti-like-virus shares 75-86% aa identity with Atrato partiti-like virus 2. We also found the S and L segments of Anopheles triannulatus orthophasmavirus (92% identity) in Anopheles lutzi from Chapada dos Guimarães. The identification of these putative novel viruses underscore the wide dispersion of viruses in culicid hosts contributing to extensions on mosquito virome descriptions.
