Book Description
The genus Lasiopogon is a widespread group of robber flies (Diptera: Asilidae) inhabiting the north temperate parts of the Earth. This study is the first to examine the genus as a complete entity and clearly define intrageneric relationships. It is also the first to pay special attention to the male and female genitalia, important structures in the taxonomy of the genus. There are 118 known species of Lasiopogon, about half of these yet to be described. Dr. Cannings gives a cladistic overview of some defined species groups, and provides a detailed taxonomic and phylogenetic analysis of the 7 species groups and 29 species in the opaculus section, comprising about 25 per cent of the genus. He describes 14 new species in this section and redescribes the others. Dr. Cannings also offers a biogeographic hypothesis of the history of Lasiopogon, suggesting that the genus may have originated in Laurasia as early as the late Jurassic period.

Book Description
"Abstract: Nearctic species of Lasiopogon Loew comprising the bivittatus section (the bivittatus group sensu Cannings 2002) are revised, with the description of 13 new species, elevation of one subspecies to species, and redescriptions of 13 previously described taxa. An updated key to western Nearctic Lasiopogon adults is provided, as are notes on taxonomy, distribution, phylogeny, and ecology. A Bayesian species tree for 67 species of Lasiopogon is estimated from one mitochondrial (COI) and three nuclear protein-coding loci (AATS, PEPCK, Wg), and compared to a previously published morphology-based phylogeny. The following new species of Lasiopogon are described (assigned to the bivittatus section except as noted): L. anaphlecter sp. nov., L. apoecus sp. nov., L. asilomar sp. nov., L. bitumineus sp. nov., L. canningsi sp. nov., L. condylophorus sp. nov., L. esau sp. nov., L. karli sp. nov. (assigned to cinereus group of opaculus section), L. nelsoni sp. nov., L. odontotus sp. nov., L. sierra sp. nov., L. tumulicola sp. nov., L. wilcoxi sp. nov.; L. puyallupi Cole & Wilcox 1938 stat. nov. is elevated from subspecies; and the following previously described species are considered valid: L. actius Melander 1923, L. albidus Cole & Wilcox 1938, L. arenicola (Osten Sacken 1877), L. bivittatus Loew 1866, L. californicus Cole & Wilcox 1938, L. dimicki Cole & Wilcox 1938, L. drabicolum Cole 1916, L. gabrieli Cole & Wilcox 1938, L. littoris Cole 1924, L. ripicola Melander 1923, L. willametti Cole & Wilcox 1938, L. zonatus Cole & Wilcox 1938. The species L. martinensis Cole & Wilcox 1938 is considered valid but transferred to the tetragrammus group of the opaculus section. Keywords: Diptera, robber fly, assassin fly, Stichopogoninae, species tree"--Page 3.

Book Description
While volume 1 includes several introductory chapters and treats 42 families of flies in the Lower Diptera, volume 2 covers the remaining 64 families of flies that make up the Higher Diptera (or Cyclorrhapha). These include families of house flies, fruit flies, bot flies, flower flies and many other lesser-known groups. The text is accompanies by over 1660 line drawings and photographs.
