A typical specimen is an almost completely preserved fossil.
Body length about 8 mm. The head is bent down and not inserted into the protorax, the body is convex, the pygidium is absent, the legs are simple, the claws of the legs are comb. The exact systematic position of the genus has not been determined, except that it belongs to the superfamily Tenebrionoid ( Tenebrionoidea , in which there are about 30 families and about 30,000 species) and is its oldest representative. Earlier, about 10 species from the Cretaceous and Upper Jurassic , including Jurallecula grossa Medvedev, 1969 [2] and Praemordella martynovi Scegoleva-Barovskaja, 1929 [3] (both species from the Jurassic deposits of Kazakhstan ), were attributed to the most ancient Tenebrionoid beetles. The species was first described by fingerprints in 2011 by Chinese paleoentomologists B. Wang and H. Zhang (Bo Wang and Haichun Zhang, State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences , Nanjing , China ) and named jurassica after the geological Jurassic period. The generic name is given by the name of the city of Wuhua Town (Ningcheng County), the location of the discovery of the type series [1] [4] .
