First fossil thaneroclerid beetle from mid-Cretaceous Burmese amber (Coleoptera: Cleroidea: Thanerocleridae)

Cai, C. & Huang, D., January 2018. First fossil thaneroclerid beetle in Upper Cretaceous Burmese amber (Coleoptera: Cleroidea: Thanerocleridae). Alcheringa 42, 115–119. ISSN 0311-5518.

Thanerocleridae is a small family of Cleroidea with no fossil representatives to date. Here we describe and figure the first fossil representative of Thanerocleridae, Cretozenodosus fossilis gen. et sp. nov., from the mid-Cretaceous amber of northern Myanmar. Cretozenodosus is referred to the extant subfamily Zenodosinae as evidenced by its open procoxal cavities and transverse procoxae. Cretozenodosus has close affinities with the North American Zenodosus Wolcott, suggesting that modern Zenodosinae is probably a relict group. Our discovery of a new thaneroclerid genus from Burmese amber suggests that Thanerocleridae originated no later than the mid-Cretaceous.
