Type material. Holotype: MGUH 34839 (accession number GM 2024.15), a nearly complete forewing collected on 13 August 2024 by John Frandsen (Erslev, Denmark) and deposited in the collection of the Natural History Museum of Denmark.

Type locality and horizon. Denmark: northern Jutland : north cost of Fur Island near Gammelgård Strand (56.841262N, 8.992038E); Fur Formation, lower part of Knudeklint Member (ash layers -24 to -29); earliest Eocene.

Etymology. From the surname of John Frandsen (Erslev, Denmark), collector of the holotype.

Description. Forewing ca. 16.2 mm long as preserved (estimated complete length ca. 16.7), 4.5 mm wide. Costal space dilated proximally, heavy constricted before pterostigma. Subcostal veinlets simple, widely spaced. Part of Sc closing pterostigma distally (distad distal crossvein between Sc, RA) nearly straight. Pterostigma dark, elongated, veinlets within it indiscernible; distal crossvein between Sc, RA located in distal part of pterostigma. Subcostal space relatively narrow, dilated before pterostigma; with three crossveins detected: basal one indiscernible or absent; two closely spaced intermediate ones distad origin of RP; one distal one very short. RA distally with two preserved simple veinlets (at least three in live). RA space narrowed toward apex, with three crossveins. RP originates rather far from wing base (at ca. 0.26% complete length), with 12 branches; all preserved branches forked once (some distal branches possibly simple). M basally appears to be fused with R, but might only be very close; forked far distad origin of RP. MA, MP each forked once. Fork of Cu not preserved. CuA pectinately forked, with two short simple branches. CuP, A1 deeply forked with all branches simple. First (basal) gradate series of crossveins not preserved. Second series represented by three crossveins: 2r-m connects stem of RP and MA; 2m-cu connects MP and CuA slightly proximad 2icu; 2icu connects CuA, and anterior branch of CuP (proximal crossvein between RA, RP may belong to this series). Third series absent (intermediate proximal crossvein between RA, RP may belong to this series). Fourth (outer) series complete, nearly parallel to posterior margin, with 14 crossveins from distal branch of RP to CuA. Wing maculation probably absent.
