Three new species of Dichotomius Hope, 1838 (Coleoptera: Scarabaeidae: Scarabaeinae) from Mexico and Central America

Abstract

Three new species assigned to the satanas species-group of Dichotomius Hope (Coleoptera: Scarabaeidae: Scarabaeinae) are described from North and Central America: Dichotomius pisuicas Solís and Kohlmann, new species, from the Caribbean slope of Honduras to Panama; D. lucifer Solís and Kohlmann, new species, from the Costa Rican and Panamanian Pacific rainforests; and Dichotomius chamuco Solís and Kohlmann, new species, from Mexico to Honduras. A description, diagnosis, images, and distributional map are presented for each species.
