A contribution to the taxonomy of eucnemidae from mid-cretaceous Kachin amber (coleoptera: elateroidea)

Two new genera and species of false click beetles are described and illustrated from mid-Cretaceous Kachin amber. Yallmoleia arriagavarelai gen. et sp. nov. differs from similar species that have basally closed lateral antennal grooves on the hypomeron primarily by the absence of elytral striae and the morphology of antennae and legs. Xanrofeurya tomaszewskae gen. et sp. nov. is distinctive among Eucnemidae from Kachin amber in having basally open lateral antennal grooves on the hypomeron, and differs from extant species with this feature by its antennal morphology. Muonabuntor grandinotalis Li et al. and Jenibuntor pusillus Muona, previously described from Kachin amber, are transferred into Euryptychus LeConte as Euryptychus grandinotalis comb. nov. and Euryptychus pusillus comb. nov. Sieglindea antiqua Muona, which was claimed to originate from Kachin amber, is instead suggested to be from Eocene Baltic amber.
