Abstract

González VH. 2004. A gynandromorph of Megachile ( Austromegachile) montezuma check for this species in other resources Cresson (Hymenoptera: Apoidea, Megachilidae).Entomotropica 19(3): 155-156. A mixed gynandromorph of Megachile ( Austromegachile ) montezuma is described from a single specimen from Brazil. The gynandromorph has a head that resembles a male but with mixed male and female features, whereas the mesosoma and metasoma are mostly male and female in characters,respectively.The possibility of as yet unknown developmental mechanism that promotes gynandromorphism in Megachile over other bees is also discussed, given its higher frequency of occurrence in the genus than in other bees, and its highly ecological and morphological diversity.

Keywords
bees, Megachilini.

Resumen

González VH. 2004. Un ginandromorfo de Megachile ( Austromegachile) montezuma check for this species in other resources Cresson (Hymenoptera: Apoidea, Megachilidae).Entomotropica 19(3): 155-156. Se describe un ginandromorfo mixto de Megachile ( Austromegachile ) montezuma de un espécimen del Brasil. El ginandromorfo tiene una cabeza que se parece a la del macho, pero con caracteres de la hembra y macho mezclados, mientras que el mesosoma y metasoma son principalmente macho y hembra en caracteres, respectivamente. La posibilidad de un mecanismo de desarrollo, todavía desconocido, que promueva el ginandromor?smo en Megachile sobre otras abejas también es discutida, dada su alta frecuencia de ocurrencia en el género, más que en otras abejas, y su alta diversidad ecológica y morfológica.

Palabras-clave
abejas, Megachilini.
