    • the tergite have white base and dark apical





 4. Species of Culex:

no centre white band at the proboscis



  • Culex fuscocephale



No center white band at the tergite of the abdomen like Culex quinquifasciatus. The abdomen is all dark.




  • Culex gelidus - 2/3 of the sputum cover with white scale.
