Anopheles Celia subpictus is a species complex of four species A, B, C and D of mosquito belonging to the genus Anopheles. The genus Anopheles has been subdivided into seven subgenera — Anopheles , Baimaia , Cellia , Kerteszia , Lophopodomyia , Nyssorhynchus and Stethomyia — based primarily on the number and positions of specialized setae on the gonocoxites of the male genitalia. Within the subgenus but above the level of species a number of additional taxonomic ranks have been created. While not officially recognised they are in widespread use.

Taking into consideration the uncertainty regarding identification, within the Subpictus Complex, species B is the only species restricted to coastal brackish-water habitats, with species A, C, and D generally found in fresh-water sites including riverine pools and rice fields. Species A has been recorded in brackish-water coastal habitats, showing some level of salt tolerance, but densities only increased at these sites after rain diluted the percentage of salinity.
All four species have been recorded in waters with salinity ranging between 0. Larvae of the Subpictus Complex are found in both clear and turbid waters but have been reported from highly polluted habitats including sites contaminated with organic waste such as waste stabilisation ponds, street pools and drains.
Habitats may be exposed and sunlit and larvae are frequently associated with floating algae or other vegetation. Natural larval habitats for members of the complex include lagoons, shallow ponds, marshes, slow-flowing rivers, natural pools and margins of small streams, but the species are also highly associated with rice fields and irrigation schemes, specifically in the earlier stages of rice cultivation. Larvae have also been collected from small, artificial containers, including intra-domestic earthen pots, tanks and barrels.
Members of the Subpictus Complex are generally zoophilic, however species B will readily bite humans. Bloodmeal analyses from resting collections have revealed a preference for bovine blood. No clear predilection for either indoor or outdoor biting has been reported, however, An. Anopheles subpictus appears overall to exhibit an endophilic resting habit. The role in malaria transmission played by each species is not clear.
Anopheles subpictus s. Species B is frequently reported as a vector in coastal areas of southeastern India and there is also some evidence of vectorial capacity in this Complex from inland areas of India and Sri Lanka.

Anopheles subpictus sensu lato is a major malaria vector in South and Southeast Asia. Based initially on polytene chromosome inversion polymorphism, and subsequently on morphological characterization, four sibling species A-D were reported from India. The present study uses molecular methods to further characterize and identify sibling species in Sri Lanka. Mosquitoes from Sri Lanka were morphologically identified to species and sequenced for the ribosomal internal transcribed spacer-2 ITS2 and the mitochondrial cytochrome c oxidase subunit-I COI genes. These sequences, together with others from GenBank, were used to construct phylogenetic trees and parsimony haplotype networks and to test for genetic population structure. Phylogenetic analysis showed that species A and species B do not form a monophyletic clade but instead share genetic similarity with Anopheles vagus and Anopheles sundaicus s.

Anopheles subpictus sensu lato , a widespread vector of malaria in Asia, is reportedly composed of four sibling species A-D based on distinct cytogenetic and morphological characteristics. However An. Specimens with morphological characteristics of all four Indian An. Sibling species A, C and D tended to be predominant in inland, and An. Sibling species C was predominant in both adult and larval inland collections.
