Sikhotealinia is a genus of beetle containing a single species, Sikhotealinia zhiltzovae, which is the only living representative of the family Jurodidae, with the only other extant fossils of the family having been uncovered in Transbaikal. It was discovered in 1996 along the environs of the Sikhote-Alin mountain range in Outer Manchuria within Russia's Far East region.[1] This "living fossil" is unique in having three ocelli on its forehead, a condition otherwise unknown in the entire order Coleoptera, whether extinct or living - though it is common in other orders, and generally considered a groundplan character for neopteran insects. Sikhotealinia and its extinct relative Jurodes are considered as a sister group to all other archostematan beetles.[2]
Its uncovering within the Sikhote-Alin has been a rare discovery within the Jurodidae family, which has been commonly called "most mysterious representatives of beetles."[3] However, nothing else has yet been currently established with regards to the original area of distribution, the habitat, the biology and the immature stages of this species.[4]
