Аннотация: The fossil record of click beetles (Coleoptera: Elateridae) in Cretaceous has been only poorly documentedso far. In this study, we describe Burmophysorhinus dusaneki gen. et sp. nov. based on a single, relativelywell-preserved, specimen from the mid-Cretaceous Burmese amber. This species represents the fourthspecies of the subfamily Elaterinae known from the Burmese amber. It is morphologically similar to therecently described Dariuszelater tarnawskii Zhao et al. 2022, with which it shares the complete frontalcarina, strongly developed proximal portion of metacoxal plates, tibiae with strongly developed spurs,and long first tarsomeres. Based on this combination of characters, we tentatively place both taxa in thetribe Physorhinini. One of the principal characters usually used for the definition of Physorhinini is thepresence of ventral lobe on each tarsomere III. Since this is not present in both fossil taxa, only furtherdiscoveries of Mesozoic Physorhinini may help to elucidate if they originally have had simple tarsi andonly later during their evolution acquired ventrally lobate tarsomere III, or if they have both simple andlobate tarsomeres III already during their early diversification. The current concept of Physorhinini, aswell as of all other tribes in Elaterinae, should be re-evaluated using more lines of evidence. Additionally,we added the identification key to the Elaterinae from Burmese amber.
