An amber double first: a new brochocolein beetle (Coleoptera: Archostemata) from northern Myanmar

The first brochocolein beetle is described from Burmese amber, Brochocoleus caseyi sp. nov., (Insecta: Coleoptera: Archostemata). It is also the first brochocolein in amber to be described from the fossil record; the beetle's distinctive morphology includes an elongate head combined with a squat body form. Two additional brochocolein species in Burmese amber are briefly discussed, showing that this extinct, mainly late Mesozoic, archaic beetle group was still relatively diverse in the mid-Cretaceous.
