title: Description of the larva of Amblyomma longirostre (Koch,1844)(Acari: Ixodidae) by light and scanning electron microscopy.
abstract: The description of the larva of Amblyomma longirostre (Koch, 1844) is based on optical and scanning electron microscopy. Larvae (F1) were obtained under laboratory conditions from an engorged A. longirostre female, which had been collected on a Coendu prehensilis (Linnaeus) (Rodentia: Erethizontidae) from the Jaraguá Mountain, São Paulo municipality, State of São Paulo, Brazil. Several characters are presented including the chaetotaxy of idiosoma, palps and Haller's organ, campaniform sensillum on festoons and measurements. In addition, the relationship of A. longirostre larva to other Neotropical Amblyomma spp. larvae is discussed.
