Resumo
Gynandromorphs are individuals that display both male and female features throughout the body and are rarely found in nature. We document and describe two new gynandromorphs of the large carpenter bee Xylocopa (Neoxylocopa) augusti reared from a trap-nest in La Plata, Buenos Aires, Argentina. In addition, based on a literature review, we assessed the frequency of the different types of gynandromorphs, and the body part affected, among large carpenter bees. Both gynandromorphs were assigned to the mixed category, the most common category reported in the literature (22 of 25 specimens). The remaining three specimens exhibit a bilateral pattern in all tagmata. The presence of both sexes' secondary sexual characteristics occurred more frequently on the mesosoma than on the head or metasoma. Trap nests used in bee hotels promote the conservation and study of wild bees and might facilitate the discovery of rare cases of gynandromorphs that would remain unknown otherwise under normal nesting conditions in the wild.(AU)

O Zoológico Municipal de Guarulhos, localizado no estado de São Paulo, recebe e recupera animais silvestres do próprio município e de alguns municípios limítrofes. Entre os anos de 1997 e 2016 foram coletados carrapatos de animais silvestres (Cariama cristata, Buteo brachyurus, Alouatta guariba, Bradypus variegatus, Tamandua tetradactyla, Puma concolor, Cerdocyon thous, Nasua nasua, Mazama gouazoubira, Didelphis aurita, Sphiggurus villosus, Myocastor coypus e Hydrochoerus hydrochaeris) atendidos pelo Zoológico. Foram identificadas as seguintes espécies de carrapatos: Amblyomma aureolatum (Pallas, 1772), Amblyomma calcaratum Neumann, 1899, Amblyomma dubitatum Neumann, 1899, Amblyomma longirostre (Koch, 1844), Amblyomma nodosum Neumann, 1899, Amblyomma parkeri Fonseca e Aragão, 1952, Amblyomma sculptum Berlese, 1888, Amblyomma varium Koch, 1844, Haemaphysalis juxtakochi Cooley, 1946, Ixodes loricatus Neumann, 1899 e Rhipicephalus sanguineus sensu lato (Latreille, 1806). Apesar de todas as associações carrapato-hospedeiro já terem sido previamente relatadas no território brasileiro, o presente estudo registra pela primeira vez um ginandromorfo de A. dubitatum.
The Municipal Zoo of Guarulhos, located in the state of São Paulo, receives and recovers wild animals from the Guarulhos municipality and from some neighboring municipalities. Between the years of 1997 and 2016 ticks were collected on wild animals (Cariama cristata, Buteo brachyurus, Alouatta guariba, Bradypus variegatus, Tamandua tetradactyla, Puma concolor, Cerdocyon thous, Nasua nasua, Mazama gouazoubira, Didelphis aurita, Sphiggurus villosus, Myocastor coypus, and Hydrochoerus hydrochaeris) attended by the Zoo. The following tick species have been identified: Amblyomma aureolatum (Pallas, 1772), Amblyomma calcaratum Neumann, 1899, Amblyomma dubitatum Neumann, 1899, Amblyomma longirostre (Koch, 1844), Amblyomma nodosum Neumann, 1899, Amblyomma parkeri Fonseca and Aragão, 1952, Amblyomma sculptum Berlese, 1888, Amblyomma varium Koch, 1844, Haemaphysalis juxtakochi Cooley, 1946, Ixodes loricatus Neumann, 1899, and Rhipicephalus sanguineus sensu lato (Latreille, 1806). Although all tick-host associations have previously been reported in Brazilian territory, the present study records for the first time a gynandromorph of A. dubitatum.
