The Anopheles albitarsis complex with the recognition of Anopheles oryzalimnetes Wilkerson and Motoki, n. sp. and Anopheles janconnae Wilkerson and Sallum, n. sp. (Diptera: Culicidae)

Abstract

The Anopheles (Nyssorhynchus) albitarsis complex includes six species: An. albitarsis, Anopheles oryzalimnetes Wilkerson and Motoki, n. sp., Anopheles marajoara, Anopheles deaneorum, Anopheles janconnae Wilkerson and Sallum, n. sp. and An. albitarsis F. Except for An. deaneorum, species of the complex are indistinguishable when only using morphology. The problematic distinction among species of the complex has made study of malaria transmission and ecology of An. albitarsis s.l. difficult. Consequently, involvement of species of the An. albitarsis complex in human Plasmodium transmission is not clear throughout its distribution range. With the aim of clarifying the taxonomy of the above species, with the exception of An. albitarsis F, we present comparative morphological and morphometric analyses, morphological redescriptions of three species and description of two new species using individuals from populations in Brazil, Paraguay, Argentina and Venezuela. The study included characters from adult females, males, fourth-instar larvae, pupae and male genitalia of An. albitarsis, An. marajoara, An. deaneorum and An. oryzalimnetes n. sp. For An. janconnae n. sp. only characters of the female, male and male genitalia were analyzed. Fourth-instar larvae, pupae and male genitalia characteristics of all five species are illustrated. Bionomics and distribution data are given based on published literature records

Genetic Structure of Anopheles (Nyssorhynchus) marajoara (Diptera: Culicidae) in Colombia

“…albitarsis F are the only ones recorded for this complex in Colombia. 11 Previously, three genetic studies have been carried out with An. marajoara in Brazil.…”

Redescription of Anopheles (Nyssorhynchus) antunesi Galvão & Amaral and description of a new species of the Myzorhynchella Section (Diptera: Culicidae) from Serra da Mantiqueira, Brazil

“…The subgenus Nyssorhynchus Blanchard includes some of the most important vector species of human malaria parasites in Central and South America (Sallum & Wilkerson 1997) and is divided into three sections, the Albimanus, Argyritarsis and Myzorhynchella Sections (Harbach 2008). The Albimanus Section includes 19 formally recognized species (Faran 1980), the Argyritarsis 11 species (Linthicum 1988, Rosa-Freitas 1989, Motoki et al 2009) and the Myzorhynchella four species, i.e., Anopheles lutzii Cruz, Anopheles parvus (Chagas), Anopheles nigritarsis (Chagas) and Anopheles antunesi Galvão & Amaral (Galvão 1941). These four taxa were described from specimens collected in Brazil (Belkin et al 1971) and there is no epidemiological evidence supporting the involvement of any Myzorhynchella species as vectors of pathogens.…”
