| A new species of Homalocerus Schoenherr from the Atlantic coast of the State of São Paulo, Brazil (Coleoptera, Belidae, Belinae), with notes on color pattern and on the sclerites of the internal sac. Homalocerus bimaculatus sp. nov. (type locality: Brazil, São Paulo) is described and illustrated, and comments on the sclerites of the internal sac of aedeagus and on color pattern are provided. The new species is compared to other similar species of the genus, being distinguished by having three clusters of carmine pubescence on pronotum and two lateral whitish oval spots located slightly before the middle of each elytron. Six species of Homalocerus, including the new one, are known from the State of São Paulo. The previously published identification key for... |

| Pimelerodius punctiventris sp. nov. (type locality Brazil, Amazonas, Itacoatiara) is described and illustrated. The new taxon is compared with similar species, being distinguished from the other 12 known species of the genus by the presence of punctures in ventrite I. The available published key for identification of species of Pimelerodius is adapted to include the new species. A modification of the generic description of the aedeagus of Pimelerodius is provided, a necessity due to the differences observed in the aedeagus of the new species. The occurrence of P. motacilla (Boheman, 1843) in the Amazon Region, recorded in sympatry with P. punctiventris in Itacoatiara, AM, is discussed and confirmed, based on the study of 41 available specimens. |

| Heilipus odoratus sp. nov. (type locality: Brazil, Amazonas, Manaus) is described based on adults reared from seeds of Aniba rosaeodora Ducke (Lauraceae), popularly called "pau-rosa". The species is spermophagous and develops from egg to adult inside the seeds. The new taxon is compared with the similar Heilipus draco (Fabricius, 1801). Illustrations of larva, pupa, adult and of important structures for species identification are given, including the male and female genitalia, figured for the first time for a species of Heilipus. |

| Three main concepts of "pre-pupa" are recognized here in the Holometabola: i) pre-pupa without a distinct moult but with a short quiescent period followed or not by slight modifications of the last larval instar form of body - this type corresponds to the pharate pupa; ii) pre-pupa with a distinct moult, and a quiescent resting period followed by slight form modifications (mainly in the mandibles and color pattern) with a variable period of diapause (ex. Hymenoptera-Symphyta); iii) pre-pupa with a distinct moult, a quiescent period not related to the diapause phenomenon, and distinct morphological modifications (Coleoptera-Mycteridae). |
