RESUMO
A new species Dorynota phoenix Simões and Sekerka, new species is described and figured from Mato Grosso state of Brazil. The new species belongs to the D. monoceros species-group and is compared to morphologically similar taxa. Updated key to the nominotypical subgenus of Dorynota is provided.
RESUMO
A growing number of cases of the spread and establishment of non-native species outside their previously known ranges has been reported in recent years. Here we report new distributional records of Lepturges (Lepturges) limpidus Bates, 1872 (Cerambycidae) from Argentina and investigate whether these records could represent established populations. We constructed ellipsoid envelope models to characterize climatic niches of L. limpidus, identified areas of climatic suitability, investigated the status of new records as climatic outliers, and evaluated its dependency on its known hostplant as a limiting factor for the beetle distribution. Results indicate widespread climatic suitability in the Neotropical Region, and new records are not outliers with regard to the climatic profile of L. limpidus. Association with its known hostplant is non-dependent, indicating that the species might utilize different hosts plants. New records likely represent established populations, but targeted surveys should be carried out to detect new arrivals and enable the installation of mitigation and control measures.
RESUMO
The Greater Antilles genus Paratrikona is revised. One new species is described from Cuba: Paratrikona blakeae Simões new species. An updated identification key to the species of the genus and new distributional records are provided.

Immatures of Mesomphalia gibbosa (Fabricius, 1781) and Mesomphalia turrita (Illiger, 1801) (Coleoptera, Chrysomelidae, Cassidinae, Mesomphaliini) are described based on specimen collections from Rio de Janeiro state, Brazil. The last-instar larva and pupal exuviae of M. gibbosa (Fabricius, 1781) and the eggs, first-instar larva, and pupa of M. turrita (Illiger, 1801) are described, photographed and illustrated, with emphasis on chaetotaxy. Additional notes on their biology are presented.

Host plants of Cerambycidae and Vesperidae (Coleoptera, Chrysomeloidea) from South America. This paper offers a contribution to the knowledge on host plants of Cerambycidae and Vesperidae (Coleoptera, Chrysomeloidea) from South America. A total of 211 species of longhorn beetles belonging to 111 genera, 49 tribes, five subfamilies and two families are presented with records of host plants. Data on 259 species of host plants distributed among 188 genera and 69 families are listed with the beetle species.
Plantas-hospedeiras de Cerambycidae e Vesperidae (Coleoptera, Chrysomeloidea) da América do Sul. Uma contribuição ao conhecimento de plantas-hospedeiras das famílias Cerambycidae e Vesperidae (Coleoptera, Chrysomeloidea) da América do Sul é apresentada. Listam-se 211 espécies com registros de plantas hospedeiras, distribuídas em 111 gêneros, 49 tribos, cinco subfamílias e duas famílias. Os dados de plantas-hospedeiras associadas aos besouros totalizam 259 espécies distribuídas em 188 gêneros e 69 famílias.
RESUMO
Male and female reproductive systems of Stolas conspersa (Germar) (Coleoptera, Chrysomelidae, Cassidinae). The male and female reproductive systems of Stolas conspersa (Germar, 1824) are described and illustrated for the first time. The male reproductive system shows no difference from the subfamily pattern, which is a tubular well-developed median lobe; "Y", "V" or T-shaped tegmen; reduced pygidium; internal sac membranous and tubular; flagellum generally well developed needle-like structured and gastral spiculum absent. However, the female differs from the pattern proposed for Stolas in two aspects: ovary with 28 ovarioles and a reduced ampulla with indistinct velum.
Sistema reprodutivo masculino e feminino de Stolas conspersa (Germar) (Coleoptera, Chrysomelidae, Cassidinae). O sistema reprodutivo do macho e fêmea de Stolas conspersa (Germar, 1824) são descritos pela primeira vez. Neste estudo, foi observado que o macho não diverge do padrão proposto para a subfamília, que é edeago tubular e bem desenvolvido; tégmen em forma de "Y", "V" ou "T"; pigídio reduzido; saco interno membranoso e tubular; flagellum geralmente bem desenvolvido, em forma de agulha e espículo gastral ausente. Por outro lado, o sistema reprodutor feminino diverge do padrão usual proposto para o gênero Stolas em dois aspectos: ovário com 28 ovaríolos e ampola reduzida com velum não distinto.
