Culex impudicus (F)
Culex impudicus Ficalbi, 1890
Type-loc: Italy
This species has an apical pale band on the abdomen. Similar species are Culex territans, Culex europaeus and Culex judaicus. 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.
