Coleopteran wing: Impact of folding on genesis of remigium wing venation [Russian]

摘要

The analysis of wing venation, tracheation, and folding patterns in selected representatives of over 120 beetle families revealed that all venation and folding patterns were based on a common structural plant. Despite being easily recognizable among wings of other pterygotes, this plan is derivable from the common, very primitive one. It is shared by all the endopterigotes and is especially close to the plan, characteristic of some megalopterans. Folding of the wing at rest is hypothesized to be one of the main determinatives in the evolution of the coleopteran wing venation. An original idea on how folding patterns evolved and affected some venation particulars in the beetle wing is put forth. The main stages of this process are briefly described, each corresponding to the-origin of a particular structural plan of wing. Both the adelphagan (Adephaga+Myxophaga) and polyphagan plans, including corresponding folding types, seem to be derivable from those of Archostemata.
