Mitochondrial introgression hampers the DNA barcoding of cryptic yellow fever vectors Haemagogus capricornii Lutz and Hg. janthinomys in the Atlantic Forest, Brazil [PDF]

Parasites & Vectors
Background Yellow fever is a major public health concern in Brazil, transmitted in sylvatic cycles by Haemagogus and Sabethes mosquitoes. Among them, Haemagogus janthinomys and Hg.

Evidence of a putative new species Haemagogus ‘Trinidad sp. A’ from the Caribbean sharing mitogenome lineages with species endemic to the Amazon [PDF]

Scientific Reports
Species of mosquitoes in the genus Haemagogus, native to the forests of the Caribbean, and South and Central America, are extraordinarily understudied despite their known role as sylvatic vectors of yellow fever and Mayaro viruses. Haemagogus janthinomys

Observations on Haemagogus janthinomys Dyar (Diptera: Culicidae) and other mosquito populations within tree holes in a gallery forest in the northwestern region of Sao Paulo state, Brazil [PDF]

Neotropical Entomology, 2010
In 2000, an outbreak of sylvatic yellow fever possibly occurred in gallery forests of the Grande river in the Paraná basin in the northwestern region of São Paulo state. The aim of this study was to obtain information on the bionomics of Haemagogus and other mosquitoes inside tree holes in that area.
