“…17 Morphological variation was detected in the X chromosome, which was metacentric in A. aquasalis and A. noroestensis , A. strodei , A. albimanus , acrocentric in A. argyritarsis , 17,18 A. darlingi , 11 and A. albitarsis sensu latu, 19 whereas it is metacentric in A. aquasalis and A. noroestensis , 17 and submetacentric in A. nuneztovari. 11 This pattern is observed also in Anopheles cruzii and Anopheles bellator of subgenus Kerteszia , 20,21 A. subpictus , 22 and A. gambiae species complex, serie Pyretophorus, subgenus Cellia . 23 The morphological variation of the sexual chromosome pair suggest selective pressure in these anopheline species, which is apparently occurring only at a genetic level.…”

In the chromosome arm 2L, sections 16,17,19,20,21,22,23, and 24 were subdivided into 4, 3, 4, 4, 3, 4, 3, 3, and 3 subsections, respectively. Chromosome arm 3R shows the sections 26, 27, 28, 29, 30, 33, and 34, which were subdivided into 3, 3, 4, 3, 3, 3, and 3 subsections, respectively.…”

Abstract. New photomap of Anopheles ( Nyssorhynchus ) darlingi Root, 1926, is described for a population from Guajará-Mirim, State of Rondonia, Brazil. The number of sections in the previous A. darlingi reference map was maintained and new subsections were added to the five chromosome arms. Breakage points of paracentric inversions had been previously incorporated into the photomap of this species. An additional inversion is reported, called 3Lc, totaling 14 inversions in the A. darlingi chromosome arms. The proposed photomap is potentially useful for further evolutionary studies in addition to physical and in silico chromosome mapping using A. darlingi genomic and transcriptome sequences. Furthermore, in our attempt to compare sections of the 2R chromosome arm of A. darlingi with Anopheles funestus , Anopheles stephensi , and Anopheles gambiae , we found great differences in the arrangement of the polytene chromosome bands, which are consistent with the known phylogenetic divergence of these species.

“…Chromosomal banding pattern of the ovarian polytene chromosomes had already suggested that there are three putative species under the name An. cruzii, termed as A, B, and C [26,55]. More recently, studies employing DNA sequences from nuclear genes have corroborated this hypothesis [56][57][58][59].…”

Identification of mosquito species is necessary for determining the entomological components of malaria transmission, but it can be difficult in morphologically similar species. DNA sequences are largely used as an additional tool for species recognition, including those that belong to species complexes. Kerteszia mosquitoes are vectors of human and simian malaria in the Neotropical Region, but there are few DNA sequences of Kerteszia species in public databases. In order to provide relevant information about diversity and improve knowledge in taxonomy of Kerteszia species in Peru, we sequenced part of the mitochondrial genome, including the cytochrome c oxidase I (COI) barcode region. Phylogenetic analyses structured all species of mosquitoes collected in Peru into a single clade, separate from the Brazilian species. The Peruvian clade was composed of two lineages, encompassing sequences from Anopheles (Kerteszia) boliviensis and Anopheles (Kerteszia) pholidotus. An. pholidotus sequences were recorded for the first time in Peru, whereas An. boliviensis sequences were for the first time published in the GenBank database. Sequences generated from specimens morphologically identified as Anopheles (Kerteszia) cruzii clustered into three separate clades according to the collection localities of Serra do Mar, Serra da Mantiqueira, and Serra da Cantareira, confirming An. cruzii as a species complex, composed of at least three putative species.

“…In Africa, the main vectors of human malaria parasites are Anopheles gambiae, Anopheles arabiensis, and Anopheles funestus; the corresponding main vectors are Anopheles albimanus and Anopheles pseudopunctipennis 9 in Mexico and Central America and Anopheles stephensi and Anopheles culicifacies in Asia. In South America, the vectors involved with malaria transmission belong to the subgenus Nyssorhynchus (Anopheles darlingi, Anopheles aquasalis, Anopheles nuneztovari, Anopheles oswaldoi, Anopheles triannulatus, Anopheles tadei, Anopheles konderie complex, and Anopheles albitarsis) [9][10][11] and Kerstezia (Anopheles cruzii and Anopheles bellator) 12 . Anopheles darlingi is the main vector of disease-causing parasites in South America, with geographical distribution covering the eastern Andes, Colombia, Venezuela, Bolivia, Peru, Paraguay, Argentina, Guianas, and Brazil; however, it is absent in the extreme northeastern parts of Brazil 9,13 .…”

Background: Malaria is a global health problem and is transmitted by the Anopheles species. Due to the epidemiological importance of the genus, studies on biological, phylogenetic, and evolutionary aspects have contributed to the understanding of adaptation, vector capacity, and resistance to insecticides. The latter may result from different causes such as mutations in the gene that encodes the sodium channel (NaV).Methods: In this study, the NaV subunit I scaffold of 17 anopheline species was used to infer phylogenetic relationships of the genus Anopheles using Bayesian inference. The evolutionary phylogenetic tree of the NaV gene was aligned in the AliView program and analyzed utilizing Bayesian inference, using the software MrBayes. Results:The anophelines were grouped into five well-supported clusters: 1 -Anopheles darlingi and Anopheles albimanus; 2 -Anopheles sinensis and Anopheles atroparvus; 3 -Anopheles dirus; 4 -Anopheles minimus, Anopheles culicifacies, Anopheles funestus, Anopheles maculatus, and Anopheles stephensi; and 5 -Anopheles christyi, Anopheles epiroticus, Anopheles merus, Anopheles melas, Anopheles gambiae, Anopheles coluzzii, and Anopheles arabiensis. Conclusions:The topology confirms the phylogenetic relationships proposed in studies based on the genome of some anophelines and reflects the current taxonomy of the genus, which suggests that NaV undergoes selection pressure during the evolution of the species. These data are useful tools for inferring their ability to resist insecticides and also help in better understanding the evolutionary processes of the genus Anopheles.
