cell
In adult mosquitoes, an area of wing membrane delimited by veins or by veins and the wing margin; named after the vein immediately anterior to it or after the posterior element if the vein is formed by the “fusion” of two vein branches. In many mosquito eggs, an area of the inner or outer chorion bounded by elements of the inner or outer chorionic reticulum, respectively; differing in shape and relief in different areas of the surface. When referring to the inner and outer chorion or the inner and outer chorionic sculpture, the term “cell” may be used for brevity (see inner chorionic cell and outer chorionic cell).
Cells of the outer chorion of eggs have usually been recognised as those areas separated by the outer chorionic reticulum whereas the inner chorionic reticulum usually has been thought of as a part of the inner chorionic cells. Since the former concept has existed since Nuttall & Shipley (1901) and the latter came into being at a much later date (Horsfall et al., 1952), both inner and outer chorionic cells are characterised here in the older sense.
