The fossils were recovered from the outcrops of upper Neocomian rocks dating to about 130 million years old and yielding amber produced by Kauri pines.

Lebanoraphidia was first studied by the paleoentomologists Günter Bechly and Karin Wolf-Schwenninger, both of the State Museum of Natural History Stuttgart.

The paratype female is also incomplete, with the head missing, a white "slimy" growth along the abdomen and the thorax crushed.

Overall the head capsule for the species is generally rhombohedral in outline with antennae composed of an estimated thirty eight flagellomeres.

The wings are mostly preserved, with the holotypes left forewing entire and the paratypes right hindwing only missing a section of vein structure.
