A new species of Culex (Melanoconion) from Southern Brazil (Diptera: Culicidae)

Abstract

A new species from Southern Brazil, named Culex (Melanoconion) ribeirensis is described. The description includes adults, pupal and larval stages, illustrating the morphological aspects and a picture of a breeding place. Some data about known distribution and bionomics are presented.

Aspectos ecológicos de Anopheles cruzii e Culex ribeirensis (Diptera, Culicidae) da Mata Atlântica de Morretes, Paraná, Brasil

“…C. ribeirensis permaneceu mais tempo identificado erroneamente como Culex crybda em Forattini et al 1981, Lourenço-de-Oliveira 1984, e Lourenço-de-Oliveira & Silva 1985. Os registros geográficos deste culicíneo incluem os Estados de Rio de Janeiro, São Paulo e Rio Grande do Sul (Forattini & Sallum 1985;Sallum & Forattini 1996;Cardoso et al 2005). Seu registro para o Estado do Paraná é apresentado pela primeira vez neste trabalho.…”

“…Número total de Culex ribeirensis coletados nas CDC-M/copa e CDC-M/solo em distribuição mensal e por intervalos horários na Mata Atlântica de Morretes, Paraná, Brasil, em abril de 1995 a março de 1996. Sallum 1985). Tem capacidade de domiciliação, facilmente adapta-se ao ambiente alterado pelo homem, como as áreas de projetos de colonização implantadas com o desflorestamento, mas ainda cercadas por uma floresta remanescente (Forattini et al 1986b(Forattini et al , 1987(Forattini et al , 1991(Forattini et al , 1995.…”

“…They further stated that the male genitalia are identical for Culex adamesi, Culex pedroL, and Culex crybda (identification of these species is based on external ornamentation of the adults). Forattini and Sallum (1985) stated that the male genitalia of Culex ribeirensis did not differ remarkably from those of Culex adamesi and Culex crybda. For the sake of completeness we have included illustrations of the male genitalia for these species, but the reader is referred to Sirivanakarn and Galindo (1980), Sirivanakarn and Belkin (1980), and Forattini and Sallum (1985) for diagnostic characters in other life stages which distinguish them.…”

Figure 2 of the male genitalia of Culex adamesi is based on a paratype from Panama with the following collection data: PA 666, Bocas del Tor, Almirante, "camp"; 14 or 15 Apr 1964, light trap in secondary growth.…”

Occurence of larval Culicidae (Diptera) in water retained in Aquascypha hydrophora (Fungus: Stereaceae) in Central Amazônia, Brazil

“…The first taxon includes forest-dwelling species that live in polluted or clean water (Forattini 1965). Members of the subgenus Melanoconion are collected from a wide variety of habitats including margins of streams and lakes with abundant floating vegetation and pools (artificial or natural) of water (Forattini et al 1991, Forattini & Sallum 1992. Most of the species in this subgenus have unknown biologies, but some are known to be arbovirus vectors.…”
