Abstract

We present the first cladistic analysis of genera in the family Lampyridae and other closely related beetles. A monophyletic concept of Lampyridae is established. The phylogenetic positions of the luminous cantharoid families [Omalisidae, Rhagophthalmidae and Phengodidae] in relation to Lampyridae are discussed, as well as the implications of the evolution of bioluminescence and photic signaling in this group of beetles. The Rhagophthalmidae appears to include Dioptoma and Diplocladon (formerly located in Phengodidae) and the Phengodidae apparently includes Stenocladius (formerly of Lampyridae). Harmatelia, Drilaster and Pterotus are transferred to Elateroidea insertae sedis and not included in Lampyridae where they were sometimes placed. /// Presentamos el primer análisis cladístico de los géneros en la familia Lampyridae y otros escarabajos muy relacionados. Se establece un concepto monofilético de Lampyridae. Se discuten las posiciones filogenéticas de las familias luminosas "cantharoid" [Omalisidae, Rhagophthalmidae y Phengodidae], y su relación con Lampyridae es discutida, al igual que las implicaciones de la evolución de la bioluminiscencia y señalamiento de luz en este grupo de escarabajos. La familia Rhagophthalmidae parece incluir Dioptoma y Diplocladon (antes localizados en Phengodidae) y la Phengodidae aparentemente incluye Stenocladius (anteriormente de Lampyridae). Harmatelia, Drilaster y Pterotus son transferidos insertae sedis a Elateroidea y no se incluyen en Lampyridae donde a veces han sido colocados.
