Fredwardsius

Abstract: Mosquito borne diseases remains as an importance source of morbidity and mortality in Sri Lanka. To better control vectors which transmit the diseases, updated list of the species present in the county is imperative. It is also vital in documenting the diversity of the family Culicidae. Original records were collected from a literature review to compile a list of the species recorded in Sri Lanka. This work illustrates the updated list of mosquito species in Sri Lanka and their current taxonomic status based on previous studies from 1901 to date. A total of 159 species belonging to 19 genera including sibling species, have been included in the revised mosquito checklist in Sri Lanka. The present work includes 13 species, two genera (Lutzia, Verrallina) and 9 subgenera in subfamily Culicinae, tribe Aedini of genus Aedes (Bruceharrisonius, Collessius, Danielsia, Dendroskusea, Downsiomyia, Fredwardsius, Hulecoeteomyia, Neomelaniconion, Phagomyia) in to the checklist which were not included in the previous mosquito checklist published nearly 26 years ago. However, further work is essential to refine this list and to explore the abundance of new species within the country. Improved morphological and molecular identification methods will sanction the refinement of the mosquito catalog in years to come.

Abstract: A new subgenus Fredwardsius of genus Aedes, is described and compared with other subgenera. Distinctive features of the female, male, female and male genitalia, pupa, and fourth-instar larva of the subgenus are listed. The subgenus has a distribution in southern Europe, southern Asia, and Africa.

Abstract: An important element of vector control and surveillance of mosquito-borne diseases is updated information on vector species distribution. The aim of this study was to collect available information about mosquito species reported in Extremadura between 1920 and 2020 and create a catalog that would combine both published data and our recent field identifications. An exhaustive list is hereby presented, including species status and detailed distribution maps at a municipal level as well as their importance for public health. A total of 33 species, classified into five genera: Anopheles (five species), Aedes (14), Culex (nine), Culiseta (four), and Orthopodomyia (one) has been recorded, including 31 autochthonous, one invasive, Aedes (Stegomyia) albopictus, and one disappeared since 1953, Aedes (Stegomyia) aegypti. For the first time in Extremadura, we report the presence of important vectors such as Aedes (Aedimorphus) vexans vexans and Culex (Culex) perexiguus, and the new record of six species in the province of Badajoz, namely: Aedes (Dahliana) echinus, Aedes (Fredwardsius) vittatus, Aedes (Ochlerotatus) berlandi, Aedes (Ochlerotatus) pulcritarsis, Culex (Culex) mimeticus, and Culiseta (Culiseta) subochrea. Nineteen of these species are potential vectors of medical and veterinary relevance.
