ABSTRACT. A study was made of Aleiodes species recorded in Mexico, and specimens deposited in various collections. Using the criteria of Portier and Shaw (1999), eight species groups were recognized from Mexico, with 21 described and 27 undescribed species recorded. These are first records in Mexico for A. earinos Shaw, A. graphicus (Cresson), A. notozophus Marsh and Shaw andA. politiceps (Gahan). The genus is widely distributed in Mexico, being present in 28 of 31 states. Results are discussed in relation to the richness patterns hypotheses of other authors.

El estudio se realizó con las especies de Aleiodes registradas en México y material depositado en varias colecciones. Utilizando los criterios de Portier y Shaw (1999) se reconocieron ocho grupos de especies presentes en México. Se registraron 21 especies descritas y 27 no descritas. Las especies A. earinos Shaw, A. graphicus (Cresson), A. notozophus Marsh y Shaw y A. politiceps (Gahan) son primeros registros para México. El género muestra amplia distribución en México, estando presente en 28 de los 31 estados. Se discuten los resultados con respecto a las hipótesis de otros autores sobre patrones de riqueza.
