The Oryctini (Coleoptera: Scarabaeidae: Dynastinae) it a large tribe of worldwide
distribution with approximately 26 genera and 230 species. Fourteen genera and 113
species are distributed in the Neotropical region. This group of scarab beetles is
characterized by a generally large and robust body, black or brown coloration,
exposed mandibles, protíbia tri- or quadridentate with large teeth, and pronounced
sexual dimorphism with the males possessing prominent tubercles or horns on the
head and/or pronotum. Adults are nocturnally active and generally feed on rotting
fruits or decaying vegetation. Knowledge of the tribe in the Neotropics is fragmentary,
necessitating further studies that address taxonomy, biology and geographical
distribution patterns. This study is a faunistic survey of the Oryctini of the Brazilian
Amazon. The composition of the group in the study area is 7 genera and 19 species
found in 7 states, 91 municipal districts, and approximately 167 specific localities.
States with larger number of species are Amazonas and Pará, with 17 and 13
respectively. Heterogomphus eteocles Burmeister, 1847, Heterogomphus aidoneus
(Perty, 1830), Heterogomphus telamon Burmeister, 1847, Megaceras crassum Prell,
1914, and Megaceras laevipenne Prell, 1914, are reported for the first time from the
study area. Megaceras laevipenne is reported for the first time from Brazil. The
taxomony, descriptions, distribution maps, and biological and ecological data are
provided for all species. A characters analysis is provided as well as an identification
key for all Oryctini species that occur in Brazilian Amazon. |
