Type species. Cimbrochrysa moleriensis Schlüter, 1982 , by original designation.

Emended diagnosis. May be distinguished from other genera of Nothochrysinae by a combination of the following. Forewing: (1) im broad, pentagonal [ Stephenbrooksia : very long, narrow; Archaeochrysa , Dyspetochrysa , Lithochrysa Carpenter, 1935 , Palaeochrysa Scudder, 1883 , Tribochrysa Scudder, 1883 : elongate]; (2) 2m-cu located approximately in middle of im [ Pseudochrysopa Makarkin & Archibald, 2013 , Dyspetochrysa , Lithochrysa , Palaeochrysa , Tribochrysa , Nothochrysa , Pronothochrysa : in proximal part of im; Kimachrysa, Pimachrysa , Pamochrysa , Hypochrysa , Asthenochrysa : proximad im]; (3) 2m-cu located distad proximal branch of CuA [ Asiachrysa : proximad]; (4) CuP once forked [ Danochrysa : twice forked]; (5) two gradate series in radial space [ Okanaganochrysa , Triplochrysa : three; Dictyochrysa , Adamsochrysa : four or more]. Hind wing: (6) MA fused with RP proximally for long distance [ Archaeochrysa , Stephenbrooksia , Leptochrysa : separate].

Species included. C. moleriensis (earliest Eocene of the Fur Formation, Denmark); C. americana sp. nov. and C. major sp. nov. (both from the late Eocene of Florissant, Colorado, USA).

Occurrence. The Eocene: early Ypresian of Europe and late Priabonian of North America.

Remarks. We could not examine the holotype of C. moleriensis which is apparently missing from the Fur Museum ( Denmark) where it was deposited according to the original description (Bo Schultz, pers. comm.).

The forewing venation of Cimbrochrysa is most similar to that of Asiachrysa from the Eocene Tadushi Formation of the Russian Far East. These genera differ only in small details and are probably closely related. Green lacewings with venation similar to Cimbrochrysa and Asiachrysa were therefore distributed in Eocene throughout the Holarctic (i.e., Europe, Far Eastern Asia, and western North America).
