Ptiliidae (featherwing beetles) is a group of minute staphylinoid beetles with a scarce fossil record. Here a second member of the Mesozoic genusKekveusYamamoto et al. is reported from mid-Cretaceous Burmese amber, with detailed morphology obtained through confocal microscopy.Kekveus brevisulcatusLi, Yamamoto, Newton & Cai sp. nov. shares withK. jasonYamamoto et al. the unpaired medial pronotal fovea and narrowly separated transverse metacoxae, but can be separated from the latter based on its less elongate body, shorter pronotal foveae, and much weaker transverse depression on the head. Our phylogenetic analyses support the discheramocephalin affinity ofKekveus, although its relationship with other members of Discheramocephalini cannot be confidently resolved.
