Landmark points for geometric morphometric analyses and graphic representation of geometric morphometric methods. a–f The first metatarsal segment is represented by two curves, each comprising 50 landmark points. g–l Arrows indicate Procrustes distance and Spline bending energy relative to the reference specimen, Juraphlebia eugeniae (CNU-MEC-NN2014038). a, g Non-swollen, Orthophlebia extensa (CNU-MEC-NN2014059). b, h Slightly swollen, O. elenae (CNU-MEC-NN2014005). c, i Moderately swollen, Juraphlebia eugeniae (CNU-MEC-NN2014009R). d, j Heavily swollen, Mesopanorpa luanpingensis (CNU-MEC-NN2016222). e, k Extremely swollen, O. extensa (CNU-MEC-NN2006046). f, l Slightly swollen, the new taxon of Conicholcorpa longa Zhang, Shih & Ren sp. nov. (CNU-MEC-NN2015108)
