ABSTRACT. A new spermophagous species of Heilipus Germar from the Amazonian Region (Coleoptera, Curculionidae, Molytinae). 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.
A new genus and species of the weevil tribe Entimini, Nasocomptus obyberaba gen. nov. and sp. nov., are described from the southwestern Amazonian Region (type locality: Brazil, Rondonia, Ouro Preto do Oeste). A cladistic analysis was carried out among representative species of most of the Neotropical genera, including Nasocomptus gen. nov., to provide a phylogenetic hypothesis for the tribe. A single most parsimonious cladogram was obtained: (Entimus (Nasocomptus ((Polyteles, Phaedropus) (Rhigus, Cydianerus)))). An identification key for the genera of Neotropical Entimini (except Trachyus) is furnished. The new genus is easily distinguished by two outstanding autapomorphies: anterior angle of rostrum prominent and spiked in males, and styli of female coxites ventral and pre-apical. Color photographs of the habitus of the new species and outline illustrations of structures used in the cladistic analysis are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
