REVIEW OF THE MEXICAN SPECIES OF GOLOFA HOPE (COLEOPTERA, MELOLONTHIDAE, DYNASTINAE)

The Mexican species of Golofa Hope are reviewed based on the examinati on of 610 specimens. Golofa tepaneneca, new species, from the State of Puebla, and G. xiximeca, new species, from the States of Sinaloa and Nayarit are described as new. The structures of mesotibiae, accessorie s on the internal sac of the male aedeagus, female genital plates, str idulatory files on prepygidia of both sexes, and male morphometry are used for the first time in the taxonomy of the genus. Precise ecologic al and geographical distributions are adopted as important criteria fo r the separation of the eigth Mexican species. The third-stage larvae and pupae of G. pizarro Hope and G. pusilla Anew, and third-stage larv a of G. tersander Burmeister are described, and brief biological obser vations are provided for each species. Illustrations of diagnostic str uctures are included. Separation of the subgenera Golofa and Mixigenus Thomson is supported by a number of morphological characters of adult s and larvae, and ecological distribution. Brief comments about disper sal patterns of the genus in Mexico, a key to the male and female adul ts of Mexican species, and a key to third-stage larvae of the five spe cies for which they are known are also presented.
