ABSTRACT
Monocrepidius Eschscholtz, 1829, previously Conoderus Eschscholtz, 1829, is one of the largest genera in Elateridae, with about 380 species distributed worldwide, with the majority of diversity in Australian and Neotropical regions. Several species groups have been recognized in Monocrepidius. Monocrepidius fuscofasciatus (Eschscholtz 1829) belongs to Candèze's section I with seven species distributed in South America, predominantly in Brazil. Larvae of M. fuscofasciatus is undescribed and distribution of this species is poorly known. In the present work we describe mature larva, pupa and redescribe adults of M. fuscofasciatus, and also add information about distribution of this species. Monocrepidius fuscofasciatus larva is similar to that of M. malleatus Germar, 1824, its closest species with known larva. They differ from other American species in the presence of penicillus on mandible and abdominal tergum IX more setose, with a lateral row of 6 or 7 setae. In the other species, the penicillus is absent and the lateral row bears 2 or 3 setae. These results corroborate that larval evidence is useful in the taxonomy of this genus.

Red propolis is a substance produced by bees by mixing resins from plants with wax, oils, and other secretions to protect the hive against natural enemies. Dalbergia ecastaphyllum (L.) Taub. (Fabaceae) is the primary botanical source of the Brazilian red propolis, where bees Apis mellifera L. collect a reddish resin from the stems to produce propolis. This species occurs in coastal dune and mangrove ecosystems, where local beekeepers install their beehives for propolis production. The induction of propolis production was virtually unknown. Previous reports and field evidence suggested that the reddish resin available in D. ecastaphyllum stems was not produced spontaneously but induced by the presence of a parasitic insect that feeds on the plant's stems. Research in the apiaries of the beekeepers' association of Canavieiras, Bahia, Brazil, led to the capture of a jewel beetle of an unknown species of the genus Agrilus Curtis (Buprestidae). It was confirmed that this jewel beetle is a red propolis production inductor. The adult and immature of this new species, Agrilus propolis Migliore, Curletti, and Casari sp. nov. are here described and illustrated. Behavioral information on the biology and chemical ecology confirms that the reddish resin of D. ecastaphyllum is directly related to the beetle attack and only occurs when Agrilus propolis sp. nov. adults emerge from the plant stem. This information is very important for Brazilian propolis producers interested in expanding red propolis production, which can have favorable effects on the economy of mangrove communities, promoting income generation, creating new business opportunities, and helping to sustain local communities and families.

Immature stages of four species from Brazil, belonging to three tribes of Prioninae Latreille, 1802 (Cerambycidae), are described or redescribed and illustrated: Myzomorphus quadripunctatus (Gray, 1831) (Anacolini); Pyrodes nitidus (Fabricius, 1787) (Mallaspini); Polyoza lacordairei Audinet-Serville, 1832, and Quercivir gounellei Lameere, 1912 (Meroscelisini). A characterization of described Prioninae immature stages for the American continent is included. An attempt to characterize the larvae and pupae for each tribe based on described immature stage, is also presented. Some studies consider Parandrinae as a derived group within Prioninae (paraphyletic), and therefore, suggest treating both as Prioninae. In our study, we found some immature features that can define Prioninae, and by analyzing recent studies, we defend the continuance, for now, of the current status of Prioninae and Parandrinae, until a more detailed morphological and molecular study, with a greater representation of these groups is done (including characteristics of the immature stages).
