We report the identification, synthesis, and field bioassay of a novel attractant pheromone produced by males of Eburodacrys vittata (Blanchard), a South American cerambycid beetle in the subfamily Cerambycinae. Headspace volatiles from males contained a sex-specific compound, identified as 10-methyldodecanal. In a field bioassay conducted in Brazil, significant numbers of males and females were caught in traps baited with synthesized racemic 10-methyldodecanal, consistent with the aggregation-sex pheromones produced by males of many cerambycine species. This compound represents a new structural class of cerambycid pheromones, and it is the first pheromone identified for a species in the tribe Eburiini.

Two new species of Beraba from Colombia (Bolívar) are described: Berabaanae sp. n. and Berabaangeli sp. n. The most recent key to species of the genus was modified to incorporate the new species. The male of Berabalimpida Martins, 1997 is described and illustrated for the first time. Moreover, the geographical distribution of 12 species of Eburiini is expanded.

The following new species are described - Cerambycinae, Sydacini: Sydax flechtmanni sp. nov. from Brazil (São Paulo); Eburiini: Ebrodacrys biffipradorum sp. nov. from Brazil (Roraima); - Lamiinae, Pteropliini: Ataxia piauiensis sp. nov. from Brazil (Piuaí); Calliini: Amucallia carbonaria sp. nov. from French Guiana; A. citrina sp. nov. from Guiana. Also in Lamiinae, two new genera of Onciderini are proposed. Ubytyra gen. nov., type species U. tuberosa sp. nov. from Peru (Junin) e Japi gen. nov., type species J. duartei sp. nov., from Brazil (São Paulo); Ubytyra gen. nov. can be distinguished by the sides of prothorax with long central spine rounded at apex, and this new feature among Onciderini is discussed. Japi gen. nov., is characterized by a fringe of long hairs on the inner side of antennomere III, present only in species from North and Central America, and gender comparison of these species is done and discussed. In Hemilophini, Pseudotacocha gen. nov., type species P. magnifica sp. nov. from Peru (Cuzco), are described. The new genera can be distinguished by eyes well developed, elytra with two carinae and the apices outer with short spine; a comparison with related genera is done. [PUBLICATION ABSTRACT]
