Description of the adults and pupa of Simulium (Trichodagmia) perplexum, new species (Diptera: Simuliidae)

Abstract

Simulium perplexum, new species, is described from the male, female and pupa and compared with the closely related S. guianense Wise. The distribution and biology of the new species are discussed. The confusion between S. perpelxum and S. guianense has hitherto prevented accurate identification of the primary vector of human onchocerciasis in highling, hyperendemic areas of the Amazônia focus of Brazil and southern Venezuela.

Simulium (Trichodagmia) (Diptera, Simuliidae) phylogeny revisited: the Neotropical and Afrotropical connection

“…The terminology used follows that of Adler et al (2004). To support the morphological study, we used the original descriptions of the species used as terminal taxa, all works cited in the introduction, and the following works: De-Meillon (1930, 1953; Gibbins (1935Gibbins ( , 1939; Fain (1949Fain ( , 1950Fain ( , 1951; Grenier & Douget (1949); Freeman & De-Meillon (1953); Dalmat (1955); Grenier & Grjébine (1958); Shewell (1959); Crosskey (1960Crosskey ( , 1967; Lewis (1961); Díaz-Najera & Vulcano (1962); Grenier & Le Roy-Moret (1970); ; Ramírez-Pérez (1971; Lewis & Disney (1972); Fain & Elsen (1973, 1980; Rubtsov ( , 1974; Fain et al (1982); Car (1983); Currie & Adler (1985); Maia-Herzog et al (1985); Crosskey & Santos-Grácio (1985); ; Peterson et al (1988); ; Shelley et al (1989); Adler (1990) Based on an extensive morphological study of adults, pupae, and last instar larvae, we described the characters and proposed hypotheses of primary homology (Pinna 1991). To code the characters used (Supp.…”
