Recent advances in the knowledge of Mexican Alticinae (Coleoptera, Chrysomelidae).

The present study updates previously published biodiversity/faunistics of the flea beetles of Mexico published by the author after examination of 6132 specimens from 8 institutional collections. The following 9 genera were selected as indicators of the effects of known diversity only through examination of museum specimens (i.e., "indoor collecting"): Bechyné; Chevrolat; Bechyné; Chevrolat; Bechyné; Chevrolat; Baly; Chevrolat; and Bechyné. From the specimens examined in these genera from the 8 collections, there were 394 new records for Mexican states of the 287 new species records representing 47% new records of the species recorded from those states. Total new state records 287 from 80 species. States with most new records: Chiapas (32); Nayarit (27); Sinaloa (24). 80 spp. (47%) with new state records. Baly is reported from Mexico for the first time. The current total of Alticinae in Mexico is 90 genera/626 species. The difficulties of the generic boundaries between and , and ; as well as the specific boundaries between and and the specific level pattern variation in and are discussed. , formerly placed in , is placed is considered as a new combination.
