A new species of Aleuropleurocelus (Hemiptera: Aleyrodidae) and key to the ceanothi group from Mexico

A new species of whitefly, Aleuropleurocelus tecomastans, is described. The studied specimens were found in the municipality of Acapulco, State of Guerrero, Mexico on Tecoma stans (L.) (Bignoniaceae) leaves. A dichotomous key to identify members of Aleuropleurocelus group ceanothi, defined by a transverse suture of the molt which reaches the submarginal line, is provided. Photographs of morphological pupal structures are given and diagnostic separation to other related species is discussed.
