| Morphological aspects of the male and female genitalia and their associated sclerites, abdominal tergite and sternite 8, are described, illustrated and discussed for seven species of Heilus Kuschel 1955 of tribe and subtribe Hylobiini-Hylobiina. The seven species are H. faldermanni (Boheman, 1836); H. fasciculatus (Boheman, 1843); H. freyreissi (Boheman, 1836); H. myops (Boheman, 1836); H. pupillatus (Olivier, 1790); H. rufescens (Boheman, 1836) and H. tuberculosus (Perty, 1832). |

| The swimming behavior exhibited by specimens of L. fasciatus and O. uniformis was analyzed frame-by-frame with video observation recorded with a digital camera, attached to a stereomicroscope. Adults of O. uniformis, an aquatic insect, swim with all three pairs of legs. During the process of swimming the majority of the abdomen and rostrum remain submerged, part of the fore and hind tibiae remain above the surface, while the mid tibiae remain submerged. The mesothoracic legs, during the power-stroke stage, provide the greatest thrust while the metathoracic legs provide the least forward propulsion. The prothoracic legs, extended forward, help to direct the swimming. The semi-aquatic specie L. fasciatus shows the same swimming style as O. uniformis, that... |

| Data on the occurrence of ten weevils species associated with Pistia stratiotes L. (Araceae), from Ilha de Marchantaria, Manaus (Amazonas, Brazil) are presented for the first 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 unidentified species in the Cryptorhynchinae. Among the Stenopelmini, Argentinorhynchus breyeri Brèthes, 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 affinis... |
