Culex territans (Walker, 1856)
Type-loc: USA
This species has an apical pale band on the abdomen. Similar species are Culex judaicus, Culex europaeus and Culex impudicus. While Culex territans have well developed apical bands Culex impudicus bands are narrowed or interrupted in the middle. Male genitalia characters are the most reliable to separate these species from one another.
