“…The dissection process is used for sexual confirmation of many insects, corroborating sexual identity based on morphological characteristics (NUNES et al, 2009;GEORGE et al, 2015). In this study, the dissection of adult insects also confirmed the sexual identification of O. muricatus obtained External features observed in adults of other species of the Curculionidae family that could constitute sexual dimorphism, such as length, width and pilosity of the rostrum; point of insertion of the antennae in the rostrum; and pilosity of legs or venter (VAURIE, 1973;BARRETO et al, 1999;AMBROGI et al, 2009;WILHELM et al, 2011;BARRETO;ROSADO-NETO, 2012;CAZADO et al, 2014;GEORGE et al, 2015), were not found in O. muricatus, coinciding with observations pointed out by VAURIE (1973).…”

The weevil Ozopherus muricatus Pascoe, 1872 (Coleoptera: Curculionidae) is already considered a pest in Brazil for açaí palm (Euterpe oleracea Mart.) plantations. Its presence has become more frequent and caused significant reduction in the production of açaí fruit. Studies on the biology of this insect pest are still scarce, hindering its management. For studies on pheromones, for instance, it is essential to correctly identify the sex of the insect. The objective of this study was to evaluate the existence of sexual dimorphism in pupae and adults of O. muricatus in order to allow the identification of males and females. Larvae, pupae and adults were collected from açaí plantations and kept in biochemical oxygen demand (BOD) type incubation chambers. Adults and pupae were examined under a stereomicroscope, and dimorphism was determined through observation of external morphological characteristics. In addition, adults were dissected in order to observe genitalia and confirm the sex of specimens. In the pupae, sexual dimorphism was characterized by the presence of two protuberances in the terminal ventral region of the abdomen of females, which were absent in males. In adults, sexual dimorphism was also observed, based on the final abdominal segments. In males, it was possible to see all eight abdominal tergites, while in females tergite VIII is covered by tergite VII. Thus, the sexual dimorphism present in the morphological characteristics of O. muricatus allows the distinction between males and females of this species.

Heilipus gibbus sp. nov. (type locality: Brazil, state of São Paulo, Angatuba) is described from 73 specimens. The holotype and three paratypes from the same locality were reared from larvae collected in the basis region, near the ground, of an atemoya tree (a hybrid of the sugar-apple, "pinha" or fruta-do-conde"-Annona squamosa L., and the cherymoya, A. cherimoya (Mill.), Annonaceae). Heilipus gibbus sp. nov. can cause severe injury to commercial Annonaceae, and has been misidentified in the collections and the literature as Heilipus catagraphus Germar, 1834. The new species and H. catagraphus have a very similar color pattern, but can be easily distinguished by the rostrum shape in lateral view, being humped in H. gibbus sp. nov. but evenly arcuate in H. catagraphus. Illustrations of habitus and of male and female genitalia are provided to the new species and for avocado stem boring species of Heilipus which occur in Brazil (H. catagraphus and H. rufipes). Comments are made for H. elegans Guérin, 1844, which record to Brazil is probably based on a misidentification.
