Download or read book A revision of the genus Arenivaga Rehn Blattodea Corydiidae with descriptions of new species and key to the males of the genus written by Heidi Hopkins and published by PenSoft Publishers LTD. This book was released on 2014-02-26 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Corydiidae (Polyphagidae, sensu lato) is a family of extremo-phile cockroaches that have received little taxonomic attention. Their cryptic subterranean way of life in some of the most in-hospitable parts of the planet makes the study of this group particularly difficult. Arenivaga (Rehn) is a genus of Corydiid cock-roach endemic to the American Southwest, Florida, and Mexico. This unusual group of insects, not examined in nearly a century, is revised in this volume. This work includes redescriptions of the genus and its nine known species, descriptions of 39 new species, a key to the adult males, and distribution maps for each species. A photographic series of the habitus and detailed drawing of the genitalia of each species are also provided, and novel morphological characters are described. In addition, the locality data of more than 5000 specimens used in this study is now available to researchers. Even though this research increases the number of species in Arenivaga five-fold, there is little doubt that there are many more species to be found in Mexico, which is poorly surveyed in comparison to the US terrain.

Download or read book Ecology and Biogeography of High Altitude Insects written by M.S. Mani and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: In my book Introduction to High Altitude Entomology, published in 1962, I summa rized the results of eight years' studies, mainly on the Himalaya. I have since then had the opportunity of studying the collections of high altitude insects from the Alps, Carpathians, Caucasus, Urals, Alai-Pamirs, Tien Shan, Altai and other im portant mountains of the world in different museums and institutions in Europe. Through the courtesy and generosity of the Academy of Sciences of the Union of Soviet Socialist Republics, I was also able to personally collect insects and make valuable field observations on the Caucasus, the Alai-Pamirs, Ala-Tau and the Tien Shan mountains. Through comparative studies I have tried to synthesize the fundamental principles of high altitude entomology. I have described here the distinctive characters of the high altitude environment, the ecological specializations of the high altitude insects, their ecological inter relations and the outstanding peculiarities of their biogeography. I have also pre sented here an outline of the high altitude entomology of the principal mountains of the world, with brief accounts of their orogeny, geology and vegetation. This book differs from all other contributions in the field in its comparative ecological approach and in the fact that the main emphasis is throughout on the evolution of the high altitude ecosystem as an integral part of the orogeny. High mountains are, in all parts of the world, important and independent centres of origin and differ entiation of distinctive and highly specialized ecosystems and faunas.
