Abstract

The recently reviewed subtribe Procirrina comprises eight extant genera with a predominately (sub)tropical distribution. Molecular and total-evidence phylogenies consistently recover Procirrina sister to the subtribe Pinophilina, which together form the tribe Pinophilini of the rove beetle subfamily Paederinae. Nothing from the fossil record of the tribe has ever been described, although compression fossils are known from the Cenozoic Green River Formation as well as inclusions from the Miocene Dominican and Mexican amber. Here we described †Cretoprocirrus trichotos Jenkins Shaw & Żyła gen. et sp. n., the first and thus the oldest fossil representative of the tribe Pinophilini from Upper Cretaceous Burmese amber. Phylogenetic analyses of morphological data allow its unambiguous placement in the subtribe Procirrina. †Cretoprocirrus trichotos is the second genus of Paederinae described from Burmese amber and provides an important insight into the evolution of the subfamily.
