Revision of the Neotropical termite genus Orthognathotermes Holmgren (Isoptera: Termitidae: Termitinae)

This is a taxonomic revision of the Neotropical genus Orthognathotermes Holmgren, 1910 (Termitidae, Termitinae), previously with nine species: O. aduncus, O. brevipilosus, O. gibberorum, O. heberi, O. humilis, O. insignis, O. macrocephalus, O. orthognathus and O. wheeleri. We redescribe these species and describe six new species: O. longilamina sp. nov., O. mirim sp. nov., O. okeyma sp. nov., O. pilosus sp. nov., O. tubesauassu sp. nov., and O. uncimandibularis sp. nov., based on soldiers and, when possible, imago castes along with the first description of imagos of O. wheeleri and O. heberi. We present a key for soldier identification and distribution maps for all species.

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.
