The larva of Atractocerus brasiliensis (Lepeletier & Audinet-Serville, 1825), collected for the first time in Pinus oocarpa Schiede ex Schltdl. (Pinaceae) is described and illustrated. Until now, for Lymexylidae, only the larva of Melittomma sp. (Melittomminae) was known from the neotropical region (Brazil). Biological notes, a comparison with the description of A. brevicornis, the type-species of the genus (recorded from Africa and Madagascar), and history of the known lymexylid larvae are also included.

Immatures of Syphrea uberabensis guerini Bechyné (Coleoptera, Chrysomelidae, Alticini)

Immatures of Syphrea uberabensis guerini Bechyné (Coleoptera, Chrysomelidae, Alticini). Larva and pupa of Syphrea uberabensis guerini are described and illustrated for the first time and a comparison with the described immatures of other Alticini species from Neotropical region and also with Hermaeophaga mercurialis (Fabricius, 1792), from Palearctic region, is presented. Tibouchina stenocarpa (DC.) Cogn. (Melastomataceae) (quaresmeira-do-cerrado) is registered as a new host plant for this species of Alticini.
