TL;DR: Phylogenetic analyses of DNA sequence data support a paraphyletic Mecoptera with two major lineages: Nannochoristidae + (Siphonaptera + Boreidae) and Meropidae + ((Choristollaidea + Apteropanorpidae) (Panorpidae + Bittacidae))).
Abstract: Phylogenetic relationships among members of the Mecoptera and Siphonaptera were inferred from DNA sequence data. Four loci (18S and 28S ribosomal DNA, cytochrome oxidase II and elongation factor-1α) were sequenced for 69 taxa selected to represent major flea and mecopteran lineages. Phylogenetic analyses of these data support a paraphyletic Mecoptera with two major lineages: Nannochoristidae + (Siphonaptera + Boreidae) and Meropidae + ((Choristidae + Apteropanorpidae) (Panorpidae + (Panorpidae + Bittacidae))). The flea family Ctenophthalmidae is paraphyletic, and the Ceratophylloidea is monophyletic. Morphological evidence is discussed which is congruent with the placement of Siphonaptera as sister group to Boreidae.

TL;DR: Parsimony analysis supports the monophyly of all holometabolous insect orders except for Coleoptera and Mecoptera, but Antliophora andMecopterida are paraphyletic, and the limitations of using 18S ribosomal DNA as the sole phylogenetic marker for reconstructing insect ordinal relationships are discussed.
Abstract: Phylogenetic relationships among the holometabolous insect orders were reconstructed using 18S ribosomal DNA data drawn from a sample of 182 taxa representing all holometabolous insect orders and multiple outgroups. Parsimony analysis supports the monophyly of all holometabolous insect orders except for Coleoptera and Mecoptera. Mecoptera is paraphyletic with respect to Siphonaptera, which is nested within Mecoptera. Coleoptera is scattered as a paraphyletic assemblage across the tree topology. These data support a monophyletic Halteria (Strepsiptera + Diptera), Amphiesmenoptera (Trichoptera + Lepidoptera), Neuropterida (Neuroptera + (Megaloptera + Raphidioptera)), but Antliophora (Halteria + Mecoptera + Siphonaptera) and Mecopterida (Antliophora + Amphiesmenoptera) are paraphyletic. The limitations of using 18S ribosomal DNA as the sole phylogenetic marker for reconstructing insect ordinal relationships are discussed.

TL;DR: Although rapidly evolving genes can retain some phylogenetic signal for deep phylogenetic relationships, strong support for such relationships is likely to come from more slowly evolving genes.

TL;DR: All available 18S rDNA sequences for the Holometabola to reappraise their phylogenetic relationships will be compiled and these data and analyses will be used to highlight general problems in using molecular data to infer higher-level phylogeny.
Abstract: The purpose of this chapter is two-fold. First, all available 18S rDNA sequences for the Holometabola to reappraise their phylogenetic relationships will be compiled. Second, these data and analyses will be used to highlight general problems in using molecular data to infer higher-level phylogeny.

TL;DR: A new species of flea of the family Hystrichopsyllidae, Macropsylla novaehollandiae Hastriter, collected from Pseudomys novaehoelandiae Waterhouse near Coles Bay, Tasmania, is described.
Abstract: A new species of flea of the family Hystrichopsyllidae, Macropsylla novaehollandiae Hastriter, collected from Pseudomys novaehollandiae Waterhouse near Coles Bay, Tasmania, is described. The familial placement of the genus Macropsylla Rothschild and Stephanopsylla Rothschild are discussed.
