Description
Body length 8.4 mm, width 1.9 mm, elytra 2.4 × 1.1 mm. The head is shallow (length - 1.1 mm). Antennae 11-segmented. Pronotum transverse. Mesapatetica aenigmatica demonstrates an unusual combination of symptoms from different groups of Staphyillinids belonging to two basal subfamilies Apateticinae (for example, club-shaped tendrils, keeled tibia and bordered protonum ), and a group of a woman, a woman with a fever , a partially reduced 8th anomara, a woman, a man, a woman, and a woman with a stomach pattern. tergite and body shape). At the same time, it differs from them in several unusual features: elongated meso-cokes, IV-th and V-th abdominal tergites with a pair of basolateral carinae. The species was first described in 2014 by Chinese and American paleoentomologists C. Cai (Chenyang Cai; State Key Laboratory of Palaeobiology and Stratigraphy, Nanying Institute of Geology and Palaeontology, Chinese Academy of Sciences , Nanjing , China ), D. Huang (Diying Huang) , By Alfred F. Newton; Department of Zoology, Field Museum of Natural History , Chicago , USA and Margaret K. Thayer for fossil footprints from China [1] [2] .
