Redescription of larva, pupa and adult of Anopheles (Anopheles) annulipalpis (Diptera: Culicidae) and the removal of the specie of the Cycloleppteron Series

The redescription of male, female, pupa and larva of Anopheles (Anopheles) annulipalpis Lynch Arribálzaga, 1878 is presented. The species is included in the Cycloleppteron Series of Anopheles, although several authors consider that this is artificial. The redescription of Anopheles annulipalpis demonstrate that pupae have laticorn trumpet. By this fact is compared with An. grabhamii Theobald, 1901 and similar species of the Arribalzagia Series and Myzorhynchus Series. The laticorn type of trumpet joined the other differences and similarities found are sufficient to remove An. annulipalpis of Cycloleppteron Series and included as an unplaced member of the Angusticorn Section.
