Morphological characters for separating females of Aedes (Ochlerotatus) atlanticus Dyar and Knab and Ae. (Och.) tormentor Dyar and Knab were evaluated with reared taxonomic series and 1,858 field collected specimens. The characteristics of the median longitudinal stripe on the scutum were useful for identifying pristine specimens and these characters in combination with differences in coloration of the white basolateral scales and scales on the sterna of the abdominal segments could be useful for identifying partially rubbed specimens.
