Superfamily Polyxenoidea Lucas, 1840

Family Polyxenidae Lucas, 1840

Polyxenidae indet: Zhang, 2017: 144–145; Wesener & Moritz, 2018: 1137; this work ( Fig. 3C ). Referred material: No stated. BuB634; BuB2612; BuB2961; BuB2966; Wu F3358/Bu/CJW; Wu F3384/Bu/ CJW; Wu

F3389/Bu/CJW; Wu F3394/Bu/CJW. Preservation: Amber inclusions. Repository: NHML. BuB; Wu. Locality: Myanmar,

Kachin, Hukawng Valley, Noije Bum mine. Horizon: No stated, lowermost Upper Cretaceous, Upper Albian / Lower Cenomanian .

New records: CPAL.111: juvenile; CPAL.209: juvenile. Preservation: Amber inclusions. Repository: CPAL-UAEM. Locality: Mexico, Chiapas, Totolapa, Río Salado mine (CPAL.111) and Simojovel, Monte Cristo mine (CPAL.209. Horizon: Uppermost Simojovel Formation, Upper Oligocene-Lower Miocene.

Comments: Zhang (2017: 144–145) tentatively identified the genera Unixenus , Propolyxenus , and Polyxenus within Polyxenida . After analyzing Zhang's (2017: 154–155) photomicrographs, Wesener and Moritz (2018) found a misidentification, but consider the record of the family Polyxenidae to be valid.
