Description of the Immature Stages of Anopheles (Nyssorhynchus) rondoni (Neiva & Pinto) (Diptera: Culicidae)

摘要

The larval and pupal stages of Anopheles (Nyssorhynchus) rondoni (Neiva and Pinto) (Albimanus Section) are fully described and illustrated for the first time. The larval stage is similar to An. (Nys.) strodei Root. It can be recognized by the following combination of characters: clypeal index, 1.6- 2.9; single, aciculate setae 2,3-C; seta 3-C 0.5-0.7 the length 2-C; setae 1,2- P rarely sharing a common tubercle; seta 1-P with narrow leaflets. The pupal stage is distinguished from other Nyssorhychus by having setae 1-IV-VII and 5-V- VII branched. Only minor variation was found in setal counts between specimens from Piexoto de Azevedo, State of Mato Grosso and Bocaina, State of Sao Paulo, Brazil.
