Styporaphidia
''Styporaphidia'' is a genus of Snakefly, belonging to the extinct family Mesoraphidiidae, containing up to two species, the type species ''Styporaphidia magia'' and tentatively ''Styporaphidia? hispanica''. The genus was named from the Greek ''stypos'' meaning "stem" or "stump" and ''Raphidia'', the type genus for, and most often used as, a stem for generic names in the order Raphidioptera.〔 The species name of ''S. magia'' is from the Greek word ''mageia'' meaning "magic"〔 while the species name for ''S.? hispanica'' is from the Latin ''Hispania'' meaning "Spain" in reference to the type locality of the species.〔
==''S. magia''==
''S. magia'' is known from only the holotype, a single specimen of undetermined sex, deposited in the Department of Biology, Capital Normal University, Beijing, China as specimen number NNS-200202.〔 Preserved as a compression fossil, the individual is fossilized in a resting position giving a top view to the body and wings. Paleontologiests Michael S. Engel and Dong Ren first studied and described ''S. magia'' and the co-occurring ''Ororaphidia'' and in 2008, publishing the type description in the ''Journal of the Kansas Entomological Society'' volume 81.〔 The ''S. magia'' holotype was found in the near Daohugou Village, Inner Mongolia, China in strata belonging to the Jiulongshan Formation. This formation is dated to the early middle Jurassic and specifically Aalenian to Bajocian in age.〔 The dating places ''S. magia'' and ''Ororaphidia'' as the oldest raphidiopterans known from China to date.〔
With no ovipositor present and the terminal section of the abdomen absent it is not possible to identify the sex of the holotype specimen. The overall length of ''S. magia'' is and has a forewing length of .〔 The head is longer than it is wide and is longer than the prothorax. ''Styporaphidia'' possesses the primitive feature of two crossveins in the pterostigma.〔 This feature is found in some mesozoic genera of the Baissopteridae. However it can be distinguished from the baissopterids the lack of numerous crossveins in the radial and medial fields of the wings.〔
