Nanoraphidiais an extinctgenusofsnakeflyin the familyMesoraphidiidaecontaining the speciesNanoraphidia electroburmica[1]andNanoraphidia lithographica.[2]
The genus name is derived from a combination of the Greeknanos(dwarf) and the snakefly genusRaphidia,and the type species name from the Latinelectrum(amber) andBurma,the former name ofMyanmar.[1]The type species is known from theholotype,a single, partial adult, now deposited in theAmerican Museum of Natural Historyas specimen number Bu-092.,[1]and several additional specimens.[3]Theamberspecimen is from deposits in Tanai Village,Kachin State105 kilometres (65 mi) northwest ofMyitkyina,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 electroburmicais 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 thelithographic limestoneof theLa Pedrera de Rúbies Formationin Spain where it was found.
The genus is also the first to be described from a specimen ofold worldamber.Nanoraphidiais separatable from other Mesoraphidiidae genera by the small size of specimens and distinct vein structure of the wings.[1]The wings have an expandedcostal areawhich is similar in appearance to the costal areas inCretinocelliaandLugala.Both of these genera, however, belong to theBaissopteridaefamily and have many more crossveins and cells between Rs and M veins. The specimen showsN. electroburmicato have had a brown coloration to the body and ahyalineappearance to the wings.[1]
