Material. Holotype MNHN.F.A71352 (the distal two-thirds of a wing, very well preserved with all details of venation), stored at the Muséum National d’Histoire Naturelle , Paris, France.

Etymology. Named after our friend and colleague Dr Romain Garrouste, for his contributions to palaeoentomology.

Diagnosis. As for the genus.

Description. It is not possible to determine if the fossil is a fore- or a hind wing because these are very similar in the Caloneurodea . Length of fragment 8.1 mm, wing 2.8 mm wide; distance from wing apex and apex of ScP 5.6 mm; ScP strongly concave, ending into C opposite first fork of M; area between C and ScP 0.2 mm wide; distance between base of RP and apex of ScP 1.9 mm; convex RA smoothly posteriorly curved, with its apex 1.1 mm from wing apex; area between C and RA narrow with one row of cells; area between RA and RP slightly broader, with one row of cells, RP with three long branches, anteriorly curved, and one-two row of cells in-between; first branch 2.4 mm from base of RP and 5.4 mm from wing apex; concave M, with two long branches, anteriorly curved in their distal parts; one row of cells between M and RP and branches of M; convex CuA (+CuPaα) nearly straight, area between M and posterior wing margin with a series of veinlets distal of apex of CuA; CuA posteriorly curved apically; a series of simple veinlets in area between CuA and posterior wing margin; apical part of concave CuPaβ preserved, CuA and CuP strictly parallel, 0.5 mm apart.

Type locality and horizon. ‘ Terril N °7’, Avion, Pasde-Calais, France; Moscovian (Westphalian C /D equivalent to Bolsovian/Asturian).
