A new species of Conognatha (Pithiscus) from Minas Gerais State in Brazil (Coleoptera: Buprestidae).

Conognatha (Pithiscus) continua Pineda, Koike Barros sp. nov. (Coleoptera: Buprestidae: Stigmoderini), from southeast Brazil is described and illustrated. A simplified identification key for the Conognatha (P.) continua species-group is proposed.

Notes on Stigmoderini (Coleoptera, Buprestidae) from Brazil, with the description of a new species of Hiperantha Gistel, 1834, and new distributional records.

A new species of Hiperantha (Hyperanthoides) is described from northeast Brazil: Hiperantha (Hyperanthoides) pikachu sp. nov. Identification key of the genus Hiperantha is modified to include the new species. We also present a compilation of all species of the genus known from Brazil, including new state records for the following species: H. (s. str.) interrogationis (Klug, 1825), H. (H.) testacea (Fabricius, 1801), H. (s. str.) menetriesii Mannerheim, 1837, H. (s. str.) menetriesii ornaticollis (Gory Laporte, 1839), H. (s. str.) bella Saunders, 1869 and H. (H.) decorata (Gory, 1841).

A new genus and species of Stigmoderini Lacordaire, 1857 (Coleoptera: Buprestidae: Buprestinae) from Southeast Brazil with notes on its hypothesized mimicry complex.

Lampygnatha ikuoi gen. sp. nov. is described and illustrated from southeast Brazil. A hypothesized mimicry complex that involves the new taxon, Allocerus spencei Kirby (Coleoptera: Cerambycidae) and Cratomorphus splendidus (Drury, 1782) (Coleoptera: Lampyridae) is discussed. A key to the identification of all genera of New World Stigmoderini is presented.
