A new species and redescriptions of three species of Atractosomus Lacordaire from Brazil (Elateridae, Elaterinae)

A new species, Atractosomus amazonicus sp. nov. is described and three species, A. robustus Candèze, 1859, A. carinatus Candèze, 1859 and A. conicicollis Candèze, 1859 are redescribed and illustrated. A comparison among these species and with the type-species, A. flavescens (Germar 1839) is presented. A.amazonicus sp. nov. and A. robustus belong to group of species with 3rd and 4th antennomeres equal in size and the other studied species, to group with 3rd antennomere smaller than 4th.

Immatures of Lamprosoma amethystinum Perty, 1832 (Chrysomelidae, Lamprosomatinae)

The genus Lamprosoma Kirby, 1818 includes 128 neotropical species and 54 of them are recorded from Brazil (Monros, 1960). The first species with a described larva was L. seraphinum Lacordaire. After that, larvae and pupae of three species were described: L. bicolor Kirby, 1818, L. chorisiae Monros, 1948 and L. azureum Germar, 1824. Fiebrig (1910) described the larva of L. seraphinum Lacordaire, collected on Teminalia hassleriana Chod. (Combretaceae) of Paraguay. Moreira (1913) described L. bicolor collected on Terminalia catappa L., in Rio de Janeiro. According to him, this tree was introduced from Molucas Islands, in Oceania. He also considered it probable that L. bicolor lived on one native species of Terminalia or on another species of Combretaceae and adaptated itself to live on Terminalia catappa. Monros (1949) described L. chorisiae collected on Chorisia speciosa and Ch. insignis [ Ceiba speciosa (A. St.-Hil., A. Juss. & Cambess.) Ravenna and Ceiba insignis (Kunth) P. E. Gibbs & J. Semir] (Bombacaceae) ("" palos borrachos"") in Tucuman. Caxambu and Almeida (1999) described L. azureum collected on Psidium cattleianum Sabine (Myrtaceae)(""araca""), in Parana state. Herein, the larva and pupa of L. amethystinum collected on Terminalia catappa amendoeira-da-praia"", "" chapeu-de-sol"") in Campinas, Sao Paulo state, are described and illustrated.

Contribution towards the knowledge of Rhinotragini (Coleoptera, Cerambycidae). V. Reconsideration of Rhopalessa rubroscutellaris (Tippmann, 1960)

Corrections to the revision of Rhopalessa Bates, 1873 (Clarke et al. 2011), with the transfer of two species to a new genus, Rashelapso: R. durantoni (Peñaherrera-Leiva & Tavakilian, 2004) comb. nov., and R. schmidi sp. nov. (previously considered to be conspecific with Ommata (Rhopalessa) rubroscutellaris Tippmann, 1960 by the authors). Ommata (Rhopalessa) rubroscutellaris is now considered a junior synonym of Laedorcari fulvicollis (Lacordaire, 1868).
