Excerpt: ... tree of the suborder, and should bear the name of the man who has done more than any other worker to further our knowledge of the Odonata, namely Baron de Selys-Longchamps. In contrast to the Coenagrioninae the Protoneurinae do not have the reduction in the number of postnodals, they are as numerous in Selysioneura (fig. 153) as in Disparoneura (fig. 132). Ill--tendencies in specialization These have been rather fully discussed in previous papers, particularly by Dr. Needham (1903a) for the order Odonata as a whole, and by Dr. Calvert (1913) for the Zygoptera with special reference to the Megapodagrioninae. It is my purpose here to review their opinions and to add a few observations of my own. I think it must be apparent from the preceding discussion on the phylogeny that the outstanding features in the development of the Zygoptera are a constant reduction and simplification of venation. At any rate this is true from the standpoint of comparative morphology and to a certain degree it seems to be so paleontologically. As might be expected this reduction is to some extent accompanied by a decrease in the power of flight. Dr. Calvert says, "Many of the ideas which have been expressed on the changes which have taken place in the venation of the Odonate wings have been based on the comparative morphology of living representatives of the order or on mechanical advantage. It does not follow that these foundations are trustworthy or that there has always been mechanical improvement in the wings. Degeneration is just as probable as progressive development. The actual course of phylogeny cannot be deduced from these considerations or from the data of morphology. It seems therefore desirable to attempt to ascertain what paleontological evidence...

G. D. May 1976 Part III THEORDERSOFINSECTS THE CLASSIFICATION AND PHYLOGENY OF INSECTS The classification of insects has passed through many changes and with the growth of detailed knowledge an increasing number of orders has come to be recognized. Handlirsch (1908) and Wilson and Doner (1937) have reviewed the earlier attempts at classification, among which the schemes of Brauer (1885), Sharp (1899) and Borner (1904) did much to define the more distinctive recent orders. In 1908 Handlirsch published a more revolutionary system, incorporating recent and fossil forms, which gave the Collembola, Thysanura and Diplura the status of three independent Arthropodan classes and considered as separate orders such groups as the Sialoidea, Raphidioidea, Heteroptera and Homoptera. He also split up the old order Orthoptera, gave its components ordinal rank and regrouped them with some of the other orders into a subclass Orthopteroidea and another subclass Blattaeformia.

Available in PDF, EPUB and Kindle. Book excerpt: Dragonfly Genera of the New World is a beautifully illustrated and comprehensive guide to the taxonomy and ecology of dragonflies in North, Middle, and South America. A reference of the highest quality, this book reveals the striking beauty and complexity of this diverse order. Although Odonata -- dragonflies and damselflies -- are among the most studied groups of insects, until now there has been no reliable means to identify the New World genera of either group. This volume provides fully illustrated and up-to-date keys for all dragonfly genera with descriptive text for each genus, accompanied by distribution maps and 1,595 diagnostic illustrations, including wing patterns and characteristics of the genitalia. For entomologists, limnologists, and ecologists, Dragonfly Genera of the New World is an indispensable resource for field identification and laboratory research.
