Abstract

Meloidae (Coleoptera: Tenebrionoidea) is a diverse family of Tenebrionoidea that is estimated to be at least 130 million years old. Tere are 16 formally described fossil taxa, with the oldest originating in the mid-Cretaceous. Each formally described fossil species is reviewed here with a nomenclatural history, overview of type material, age, fossil type, and general remarks. We also address several nomenclatural issues. We formally move Zonitis magus (Heyden) new combination from Onitis Fabricius, and provide the replace¬ment name Tremembasis Saxton, Schnepp, and Powell nomen novum for Microbasis Martins-Neto, a junior homonym of Microbasis Dallas (Hemiptera: Coreidae).
