Book Description
Honeybees are as small as flies or as large as hornets, nesting in nar row cavities of trees and rocks or in the open on large limbs of trees 30 m above ground. They occur in tropical zones and in the forests of the Ural mountains, they survive seven months of winter and even longer periods of drought and heat. Historically, they lived through a extended time of stagnation in the tropics from the mid-Tertiary, but then experienced an explosive evolution during the Pleistocene, re sulting in the conquest of huge new territories and the origin of two dozen subspecies in Apis mellifera. This vast geographic and ecologic diversification of the genus Apis was accompanied by a rich morphological variation, less on the level of species than at the lowest rank, the subspecies level. Variation being exclusively of a quantitative kind at this first step of speciation, tradi tional descriptive methods of systematics proved to be unsatisfactory, and honeybee taxonomy finally ended up in a confusing multitude of inadequately described units. Effective methods of morphometric-sta tistical analysis of honeybee popUlations, centered on limited areas, have been developed during the last decades. Only the numerical characterization of the populations, together with the description of behavior, shows the true geographic variability and will end current generalizations and convenient stereotypes.

Book Description
The Neotropical Region is one of the most diverse places in the world. In this region are found most of the lineages of bees that collect floral oils, a unique characteristic among insects. The genus Centris is an extensive group of this type of bees, which are distributed from the United States to Patagonia, in the extreme south of South America. The largest, most striking, colorful and beautiful species of the genus are found in the humid forests of South America, all of them forming part of the subgenus Centris (Melanocentris). This book brings a taxonomic review of all the species of this subgenus, including the description of numerous species hitherto unknown to science. Along with the description of these species, the new subgenus Centris (Odontoxys) is also described, which contains species that are distributed from Mexico to Argentina. The book also includes redescriptions and photographs of both sexes of all species, along with distribution maps, an identification key, and lists of material examined and of floral hosts.

Book Description
Centris (Paracentris) Cameron is one of the most specious and morphologically diverse subgenera of the bee genus Centris Fabricius. These two features, along with the lack of modern taxonomic revisions make this group one of the lineages with the greatest taxonomic problems within Centridini. Partial revisions of groups of species from North and South America have been published, but none comprehensively studying all species described. In this book are studied all species of Centris (Paracentris) for the first time, providing diagnoses and redescriptions of both sexes. The following twenty one species are described as new: C. aenigmatica sp. nov., C. agyniax sp. nov., C. areequipensis sp. nov., C. aymara sp. nov., C. bagualis sp. nov., C. caribensis sp. nov., C. comonoxa sp. nov., C. diaguita sp. nov., C. euctenoda sp. nov., C. hexirrhina sp. nov., C. inca sp. nov., C. mexicanaides sp. nov., C. milluni sp. nov., C. multistriata sp. nov., C. niveiceps sp. nov., C. rasmusseni sp. nov., C. rozeni sp. nov., C. sacsayhuaman sp. nov., C. tayabamba sp. nov., C. xenopoda sp. nov., and C. yawar sp. nov., mainly from the South American Andes, including the first species recorded from the Caribbean. Centris satana Snelling is proposed as new junior synonym of C. laevibullata Snelling. In addition, the male of C. cisnerosi (Cockerell) and the female of C. euphenax Cockrell are described for the first time. An identification key, figures, maps, new distribution records, floral hosts, and an updated catalog for all species of the subgenus are also provided.

Book Description
The African continent has a rich fauna of insects, many of which are unstudied. This monograph treats one such group known as the small carpenter bees. Thirteen biological species in a new genus are described and a key for identification and details of their nests and natural enemies are given.

Book Description
The Hymenoptera is one of the largest orders of terrestrial anthropods and compromises the sawflies, wasps, ants, bees and parasitic wasps. This book examines the current state of all major areas of research for this important group of insects, including systematics, biological control, behaviour and use in education.
