Diversification patterns in geographically widespread species such as this one, are complex and therefore could impact malaria control strategies. Further studies focused on behavior, morphology, and phylogenomics will improve the understanding of the evolu- tionary patterns within An. neivai and its role as a disease vector. 1. Introduction difficulty of proper taxonomic assignment and appropriate control ac- tivities (Bickford et al., 2007; Collins and Paskewitz, 1996; Rosa-Freitas Anopheles (Kerteszia) neivai Howard Dyar & Knab, 1913 (Diptera: et al., 1998). Moreover, the vectorial capacity for transmission of Culicidae) is widely distributed from the Yucatan Peninsula in Mexico Plasmodium spp. may vary across different cryptic species of Anopheles through the northern pacific coast in Ecuador, inhabiting lowland tro- and therefore a robust taxonomic assessment of the genus is critical for pical forests and mangroves in coastal areas (Forattini, 2002; Knight malaria control efforts (Stevenson and Norris, 2017). and Stone, 1977; Zavortink, 1973). Epidemiological evidence indicates Studying the evolutionary patterns in suspected cryptic species can An. neivai serves as a vector for malaria in the Colombian Pacific Coast help to identify recently diverged species within a species complex in several localities such as Charambirá, Santa Bárbara–Iscuandé, and (Bourke et al., 2013).
