As for your other edit. Actually no. "nodal line" = "transverse flexion line". These are discrete terms, not purely descriptive, and one isn't a part of the other. Terminology in the study of palaeontinid wing morphology is not exactly standardized yet, so mentioning the two is better.
As for the dissecting through the wing wording, note that this is to differentiate it from the later form in which the nodal line is proximal to the body (i.e. the wing is not 'divided' equally/the line is not midway between the point of attachment of the forewing and the tip of the forewing). Not sure how to word it right, heh, but I think your edit made it seem even more ambiguous. -- Obsidi♠nSoul17:22, 3 August 2011 (UTC)[reply]
