Consequently, some pesticides that work on the M form no longer work on the S form. Over 3,500 species of the Culicidae have already been described. They are generally divided into two subfamilies which in turn comprise some 43 genera. These figures are subject to continual change, as more species are discovered, and as DNA studies compel rearrangement of the taxonomy of the family. The two main subfamilies are the Anophelinae and Culicinae, with their genera as shown in the subsection below. The distinction is of great practical importance because the two subfamilies tend to differ in their significance as vectors of different classes of diseases. Roughly speaking, arboviral diseases such as yellow fever and dengue fever tend to be transmitted by Culicine species, not necessarily in the genus Culex. Some transmit various species of avian malaria, but it is not clear that they ever transmit any form of human malaria. Some species transmit various forms of filariasis, much as many Simuliidae do. Taxonomy
Family
Mosquitoes are members of a family of nematoceran flies: the Culicidae (from the Latin culex, genitive culicis, meaning "midge" or "gnat"). Superficially, mosquitoes resemble crane flies (family Tipulidae) and chironomid flies (family Chironomidae). Subfamilies
Anophelinae
Culicinae

Genera
Mosquitoes have been classified into 112 genera, some of the more common of which appear below. Species
Over 3,500 species of mosquitoes have thus far been described in the scientific literature. Genomics
An analysis by Matthews et al 2018 suggests mosquito species all carry a large and diverse number of transposable elements.
(S)-Oxybutynin has not been clinically tested for its spasmolytic effects, but may be clinically useful for the same indications as the racemate, without the unpleasant anticholinergic side effects. Brand names
Oxybutynin is available by mouth in generic formulation and under the brand names Ditropan, Lyrinel XL, Ditrospam, Kentera, and Aquiette, as a transdermal patch under the brand name Oxytrol, and as a topical gel under the brand name Gelnique. See also
Arecoline
