Adiphlebia Scudder, 1885 .

—Monospecific ( A. lacoana Scudder, 1885 ). Béthoux (2009) considered this taxon as a representative of stem beetles but Kukalová-Peck and Beutel (2012) transferred it into the “ Strephocladidae ”, ignoring the synonymies proposed by Rasnitsyn and Aristov 2004), and considered this family as belonging to the Holometabola but not related to Coleoptera . Rasnitsyn and Aristov (2013) confirmed the synonymy of the Adiphlebiidae with the Ischnoneuridae (and consequently with the Anthracoptilidae ), but without new arguments. The attribution of Adiphlebia to the Anthracoptilidae would be supported by the anteriorly pectinate CuA, median vein approximating RP, ScP ending in RA, presence of numerous parallel and simple branches of main veins, Cu apparently divided into CuA and CuP, presence of numerous veinlets in costal area, numerous simple crossveins between main veins defining small rectangular cells. Nevertheless some uncertainty remains because the relative convexity of CuA and its branches is difficult to establish because of the poor preservation of this vein in all specimens studied by Béthoux or Kukalová-Peck and Beutel (2012). A crucial difference with the Anthracoptilidae (and especially Anthracoptila) is the presence of curious lateral extensions of prothorax in Adiphlebia , which would be sufficient for a family separation at least.
