A new tenebrionoid beetle genus with two species, Kulindrobor enigmaticus gen. et sp. nov. and Kulindrobor magnus gen. et sp. nov., is described from mid-Cretaceous Burmese amber. This highly distinctive genus differs from all extant tenebrionoid families. The beetle's unusual elongate and subcylindrical body with a long prothorax and appendages suggest that they may have occupied subcortical spaces. A phylogenetic analysis under maximum parsimony recovered Kulindrobor gen. nov. as sister to a member of the poorly-defined, polyphyletic Melandryidae with low support. Given that the higher classification and family boundaries in Tenebrionoidea still remain to be fully resolved and that Kulindrobor differs profoundly from all recent melandryids, we provisionally place the new genus as family incertae sedis within Tenebrionoidea.
