Insecta - Polytaxineuridae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|A. Huguet et al. 2002||Bechly (1996) proposed to characterize the Polytaxineuridae after the ‘RP” (= RP3 and 4) and MA parallel and straight, not distally curved towards the hind margin’. Unfortunately, this alleged character and the other characters listed below were based on the reconstruction of the wing of Polytaxineura stanleyi proposed by Tillyard (1935). The distal parts of these veins are not preserved in the holotype specimen, thus this character is highly putative, if not false, and cannot be used. Numerous antenodal cross-veins of the first (14) and second ranks (19); a supernumerary strong cubito-anal vein, basal of CuP; pos- sible presence of cross-veins in the median area; in subme- dian area, two cross-veins between MP&Cu and AA, basal to the base of free part of CuP.|
