Type material. Holotype : No. FM 448/74. An almost complete forewing and hind wing overlapped. Type locality and horizon. Denmark : northern Jutland ( Region Nordjylland ): Mors Island ( Morsø Kommune ): Gullerup. Earliest Eocene, Fur Formation . Remarks. Neither the holotype nor any other specimen of Cimbrochrysa moleriensis is found in any museum (FM, NHMD). Therefore, the description of Schlüter (1982) is the only information for the species. Rust (1999) assigned a forewing (MM 5-B2388) to it; however, the holotype and that specimen are surely not conspecific, as crossvein 2m-cu is located in the basal half of the intramedian cell in MM 5-B2388, as mentioned by Rust (1999) , but this crossvein is located nearly in its middle in all other known Fur species of Nothochrysinae , including C. moleriensis (2m-cu is located the proximal half of the intramedian cell in the right forewing of the holotype of D. madseni , but it is shifted distally in the left wing). Based on the proximal location of 2m-cu, MM 5-B2388 might belong to a genus similar to one of the North American genera, e.g ., Palaeochrysa Scudder, 1883 , Lithochrysa Carperter, 1935 or Archaeochrysa Adams, 1967 . Unfortunately, Rust (1999) did not provide a photograph of MM 5-B2388.
