New Early Cretaceous pentatomorph bugs from China and the systematic position of Kobdocoridae

This dataset contains the digitized treatments in Plazi based on the original journal article Dai, Rui, Chen, Ziyi, Du, Sile, Ren, Dong, Yao, Yunzhi (2025): New Early Cretaceous pentatomorph bugs from China and the systematic position of Kobdocoridae. Acta Palaeontologica Polonica 70 (1): 17-24, DOI: 10.4202/app.01186.2024, URL: doi.org/10.4202/app.01186.2024 Kobdocoridae is an extinct family of the infraorder Pentatomomorpha, mainly distributed in the Eurasia and currently comprise only nine species from seven genera in three locations.

But, the systematic position of the Kobdocoridae has long been debated. Here we describe a new genus and species Maculocris yixiani Dai, Yao, & Ren, from the Lower Cretaceous Yixian Formation in Northeastern China. This new genus is characterized by eyes relatively small, contiguous with pronotum; triangular scutellum, clavus with margins converging towards apex and large rounded patterns on the hemelytra, distinguishing it from other genera within the family.
