Two new genera and species of Ithonidae, i.e.Stictopolystoechotes sparsulusGao, Xu et Wang gen. et sp. nov. andPycnopolystoechotes striatusGao, Xu et Wang gen. et sp. nov., are described from the Middle Jurassic Jiulongshan Formation, Inner Mongolia, China. The two new genera can be assigned to thePolystoechotesgenus-group of Ithonidae by the combination of following characters: elongated forewing, Sc and RA fused distally, crossveins in radical sector sparse except for the gradate series, and simple CuP branches. The known wing markings among the JurassicPolystoechotesgenus-group were outlined, which suggested the diversification of wing markings was possibly positively associated with the species radiation of this lineage during this period. Moreover, a key to fossil genera of thePolystoechotesgenus-group was provided.LSID: urn:lsid:zoobank.org:pub:CAEEFF67-876D-4709-BE4A-18F5AB04B01DStictopolystoechotes: urn:lsid:zoobank.org:act:666ED6B2-B132-4CF4-BFB0-ED6B86EB30F4Stictopolystoechotes sparsulus: urn:lsid:zoobank.org:act:6C96432B-205F-4F39-A647-3E0048169A92Pycnopolystoechotes: urn:lsid:zoobank.org:act:1D1343DF-844E-4243-BAB9-242F6232EEBFPycnopolystoechotes striatus: urn:lsid:zoobank.org:act:B4EFBE6B-5011-4103-A65F-77D65BEC0B85
