(located on the remigium) with three branches reaching the posterior wing margin; basal to its main fork, AA(1?) emits two strong struts posteriorly; fold separating the remigium from the vannus crossing two veins (Fig. 3 [°]), and reaching the posterior wing margin at 38% of wing length; vannus moderately large, filled with numerous branches (belonging either to AA1 or AA2, see below).</p> <p>REMARKS</p> <p>The specimen most likely experienced moderate plastic deformation during fossilisation, as indicated by the forewings aspect ratio, differing in the right and left forewings. The difference observed in the fossil individual exceeds that observed between right and left forewings of Periplaneta americana (Linnaeus, 1758) (Schneider 1977: fig. 2).</p> <p>Béthoux O. et al.</p> <p>VARIABILITY</p> <p>As detailed by Schneider (1977: 81, pl. 2), the forewing venation of Phyloblatta gaudryi is particularly variable with respect to other Palaeozoic stem-Dictyoptera. In particular the number of terminal branches and branching pattern of each vein (sector) varies considerably (e.g., the number of terminal branches of the anterior branch of R ranges from 1 to 9 (Schneider 1977: pl. 2, figs 12, 11, respectively).</p> </div>	https://treatment.plazi.org/id/126F878EFFDDA24FFF7FBEC36544FD9E	Public Domain	No known copyright restrictions apply.
