  1. Culex adults are usually drab, unicolorous mosquitoes, but some species of the subgenus Culex have markings on the legs and pale spots on the wings similar to Anopheles.
  2. Culex are characterised by the presence of distinct pulvilli and the absence of prespiracular setae and postspiracular setae (the latter are present in Australian Cx. postspiraculosus). These characters, however, will not distinguish Culex from Deinocerites, Galindomyia and Lutzia.
  3. Culex differs from Deinocerites and Galindomyia in having the apical flagellomere of the antenna much shorter than the first flagellomere, and differs from Lutzia in having few (usually one) lower mesepimeral setae.
  4. Culex larvae are distinguished from other genera by the following characters: seta 2-C usually absent; seta 3-C located on dorsal side of head, sometimes absent; palatal brushes normal, not developed for grasping prey; mandible normal, without lateral lobe at base; maxillary brush present, well developed; seta 12-I and comb always present; siphon with three or more pairs of prominent setae (seta 1-S); pecten normally present; saddle usually complete, sometimes incomplete and greatly reduced but never divided into dorsal and ventral sclerites or longer than the siphon; ventral brush (seta 4-X) usually with three or more pairs of setae. See Culicini.
