[3] The amber specimen is from deposits in Tanai Village, Kachin State 105 kilometres (65 mi) northwest of Myitkyina, Myanmar.

The specimen has a badly disarticulated thorax and abdomen, which are present in the amber as integumental debris, however the head, wings, and anterior legs are in good condition.

[1] Nanoraphidia electroburmica is the smallest known Raphidioptera species, living or extinct, the fore wings being only 4.2 millimetres (0.17 in) long.

[1] The second species is named after the lithographic limestone of the La Pedrera de Rúbies Formation in Spain where it was found.

Nanoraphidia is separatable from other Mesoraphidiidae genera by the small size of specimens and distinct vein structure of the wings.
