(Araceae), from Ilha de Marchantaria, Manaus (Amazonas, Brazil) are presented for the irst time. During the period from March to August 2005, 809 weevils specimens were sampled on P. stratiotes, distributed across nine species allocated in five genera of Stenopelmini, in addition to one unidentiied species in the Cryptorhynchinae. Among the Stenopelmini, Argentinorhynchus breyeri Brethes, 1910 (N = 665) was the dominant species, with the highest abundance in July (N = 189) and the lowest in August (N = 11), while Ochetina uniformis Pascoe, 1881 (N = 63), Neochetina bruchi Hustache, 1926 (N = 45), Neohydronomus pulchellus Hustache, 1926 (N = 15), Neohydronomus afinis Hustache, 1926 (N = 10), A. squamosus (Hustache, 1926) (N = 5), Neochetina eichhorniae Warner, 1970 (N = 4), A. minimus O'Brien & Wibmer, 1989b (N = 1), and Tanysphiroideus sp. (N = 1) had lower abundances. In addition, the co-occurrences of A. breyeri, A. minimus, and A. squamosus on P. stratiotes were recorded for Brazil and the irst records of A. minimus and A. squamosus were observed for the State of Amazonas.10aNeochetina bruchi10aNeohydronomus pulchellus10aOchetina uniformis1 ade Sousa, Wesley, Oliveira1 aRosado-Neto, Germano, Henrique1 aMarques, Marinez, Isaac1 aAdis, Joachim  uhttp://www.biotaneotropica.org.br/v9n4/pt/toc
