Abstract

Pacuvia Curtis, 1844 (Coleoptera: Scarabaeidae: Melolonthinae: Diplotaxini) is taxonomically reviewed. The genus includes two species that are endemic to Chile: Pacuvia castanea Curtis, 1844 and Pacuvia philippiana Gutiérrez, 1951. An identification key is presented for the two species along with detailed distributional data. The brachyptery (flightlessness) of female Pacuvia philippiana Gutiérrez, 1951 is reported for the first time. Lectotypes are designated for Pacuvia castanea Curtis, 1844 and Liogenys gayana Solier, 1851 (a synonym of P. castanea).
