          Abstract

          Two new species of squash bees, Peponapis pacifica Ayala and Griswold sp. n. and P. parkeri Griswold and Ayala sp. n., are described and illustrated. Peponapis pacifica is oligolectic on flowers of Schizocarpum longisepalum (Cucurbitaceae) endemic to Mexico, where it is found in the tropical dry forest along the Pacific Coast, between Sonora and Chiapas and in the Balsas River basin; and P. parkeri is known only from the Pacific slope of Costa Rica. A key for the North and Central American species of Peponapis is provided.

          Se describen e ilustran 2 especies nuevas de abejas, Peponapis pacifica Ayala and Griswold sp. n. y P. parkeri Griswold and Ayala sp. n. De éstas, P. pacifica es oligoléctica sobre flores de Schizocarpum longisepalum (Cucurbitaceae), endémica de México, con distribución asociada al bosque tropical caducifolio a lo largo de la vertiente del Pacífico entre Sonora y Chiapas y en la Cuenca del río Balsas; P. parkeri es conocida sólo para la vertiente del Pacífico de Costa Rica. Se incluye una clave para las especies de América del norte y central.

          Importance of pollinators in changing landscapes for world crops.

          The extent of our reliance on animal pollination for world crop production for human food has not previously been evaluated and the previous estimates for countries or continents have seldom used primary data. In this review, we expand the previous estimates using novel primary data from 200 countries and found that fruit, vegetable or seed production from 87 of the leading global food crops is dependent upon animal pollination, while 28 crops do not rely upon animal pollination. However, global production volumes give a contrasting perspective, since 60% of global production comes from crops that do not depend on animal pollination, 35% from crops that depend on pollinators, and 5% are unevaluated. Using all crops traded on the world market and setting aside crops that are solely passively self-pollinated, wind-pollinated or parthenocarpic, we then evaluated the level of dependence on animal-mediated pollination for crops that are directly consumed by humans. We found that pollinators are essential for 13 crops, production is highly pollinator dependent for 30, moderately for 27, slightly for 21, unimportant for 7, and is of unknown significance for the remaining 9. We further evaluated whether local and landscape-wide management for natural pollination services could help to sustain crop diversity and production. Case studies for nine crops on four continents revealed that agricultural intensification jeopardizes wild bee communities and their stabilizing effect on pollination services at the landscape scale.

            The Bees of the World

            In this extensive update of his definitive reference, Charles D. Michener reveals a diverse fauna that numbers more than 17,000 species and ranges from the common honeybee to rare bees that feed on the pollen of a single type of plant. With many new facts, reclassifications, and revisions, the second edition of The Bees of the World provides the most comprehensive treatment of the 1,200 genera and subgenera of the Apiformes. Included are hundreds of updated citations to work published since the appearance of the first edition and a new set of plates of fossil bees. The book begins with extensive introductory sections that include bee evolution, classification of the various bee families, the coevolution of bees and flowering plants, nesting behavior, differences between solitary and social bees, and the anatomy of these amazing insects. Drawing on modern studies and evidence from the fossil record, Michener reveals what the ancestral bee—the protobee—might have looked like. He also cites the major literature on bee biology and describes the need for further research on the systematics and natural history of bees, including their importance as pollinators of crops and natural vegetation. The greater part of the work consists of an unprecedented treatment of bee systematics, with keys for identification to the subgenus level. For each genus and subgenus, Michener includes a brief natural history describing geographical range, number of species, and noteworthy information pertaining to nesting or floral biology. The book is beautifully illustrated with more than 500 drawings and photographs that depict behavior, detailed morphology, and ecology. Accented with color plates of select bees, The Bees of the World will continue to be the world's best reference on these diverse insects.
