Alavaraphidia
''Alavaraphidia'' is an extinct genus of snakefly in the family Mesoraphidiidae. The genus is solely known from an Early Cretaceous, Albian age, fossil amber found in Spain. Currently, the genus comprises a single species, ''Alavaraphidia imperterrita''.
==History and classification==
''Alavaraphidia imperterrita'' is known only from one fossil, the holotype, specimen number MCNA 13608. The specimen is composed of a mostly complete adult insect with the majority of the wing missing. The body is positioned so a ventral view is shown and the dorsal sides are obscured. Despite the positioning and lack of preserved wings, enough details are present to show the specimen was not from a previously described genus. The specimen is included in a small piece of amber which lacks other major inclusions. The fossil was recovered from outcrops of the Escucha Formation in Moraza, part of the Province of Burgos in Northern Spain.〔 ''Alavaraphidia'' was first studied by a group of paleoentomologists led by Ricardo Pérez-de la Fuente of the University of Barcelona and including Enrique Peñalver, Xavier Delclòs, and Michael S. Engel. Their 2012 type description of the new genus and species was published in the electronic journal ''ZooKeys''.〔 The genus name ''Alavaraphidia'' was coined by the researchers as a combination of the snakefly genus ''Raphidia'' and "Álava" which is in honor of the Álava amber deposits that preserved the specimen. The specific epithet ''imperterrita'' is from the Latin ''imperterritus'' meaning "fearless". The authors chose this as a reference to the unalterable nature of organisms trapped in amber.〔 ''Alavaraphidia imperterrita'' is one of six described snakefly species found in the Albian deposits of Cantabria.〔
