Culicoides castelloni sp. nov. from the Brazilian Amazon Region with a revision of the reticulatus species group (Diptera, Ceratopogonidae)

A new species of the reticulatus species group, C. castelloni Santarém and Felippe-Bauer, is described and illustrated based on female specimens from the state of Amazonas, Brazil. A systematic key, wing photographs and table with numerical characters of females and a synopsis of 24 species of the Culicoides reticulatus group are presented. This paper presents further new records for seven species of the reticulatus group.
