Necroraphidia
''Necroraphidia'' is an extinct genus of snakefly in the family Mesoraphidiidae. The genus is solely known from Early Cretaceous, Albian age, fossil amber found in Spain. Currently the genus comprises a single species, ''Necroraphidia arcuata''.
==History and classification==
''Necroraphidia arcuata'' is known only from one fossil, the holotype, specimen number CES 391.1. The specimen is composed of a partial isolated fore and hind-wings, leg segments, and a partial abdomen. All of the wings and the abdomen are covered in a mat of fungal hyphae. They are included in a specimen of amber with plant debris and a number of other insects, such as coleopteras, hymenopteras. and aphids. The fossil was recovered from outcrops of the Las Peñosas Formation in Rábago, part of the Cantabria autonomous community in Northern Spain.〔 ''Necroraphidia'' was first studied by 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 ''Necroraphidia'' was coined by the researchers as a combination of the snakefly genus ''Raphidia'' and the Greek ''nekros'' meaning "dead". The specific epithet ''arcuata'' is derived from the Latin ''arcuatus'', meaning "bent", a reference to the distinct structure of the pterostigmal crossvein.〔 ''Necroraphidia arcuata'' is one of six described snakefly species found in the Albian deposits of Cantabria.〔 ''Necroraphidia'' is most similar in character to ''Ororaphidia'' and ''Styporaphidia'', both from the Jurassic of Mongolia.
