          Abstract

          Abstract The subgenus Ceratina (Rhysoceratina) Michener has been known largely from southern South America, registered in Argentina, Paraguay, Uruguay and southern Brazil, with a single species, C. (Rhysoceratina) nitidifrons, from the Eastern Llanos of Colombia. Here we describe and illustrate females and males of a new species, Ceratina (Rhysoceratina) macondiana sp. nov. It is apparently endemic to the Caribbean Region of Colombia and Venezuela, extending the distribution range of Rhysoceratina to the extreme north of South America. Ceratina macondiana sp. nov. is easily separable from other Rhysoceratina species in both sexes by the color of the marginal cell, which is darker than the rest of the forewing and the dense white hairs on the lateral sides of the propodeum and posterior ridge of the scutellum.

          Resumen El subgénero Ceratina (Rhysoceratina) Michener ha sido reconocido principalmente para el sur de Sudamérica en Argentina, Paraguay, Uruguay y sur de Brasil y con una sola especie, C. (Rhysoceratina) nitidifrons, descrita para los Llanos Orientales en Colombia. En el presente trabajo se describen e ilustran hembra y macho de la especie nueva, Ceratina (Rhysoceratina) macondiana sp. nov. Hasta el momento, se registra únicamente para la región Caribe de Colombia y Venezuela, extendiendo el rango de distribución del subgénero al norte de Sudamérica. Ceratina macondiana sp. nov. se diferencia fácilmente de las otras especies del subgénero porque ambos sexos presentan la celda marginal más oscura que el resto del ala, además presentan pilosidad densa y blanquecina en las partes laterales del propodeo y en el margen posterior del escutelo.

          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.

            El género Ceratina en la Argentina: revisión del subgénero Neoclavicera subg. n. (Hymenoptera, Apidae, Xylocopinae)

            El nuevo subgénero Neoclavicera se describe para incluir su especie tipo, Ceratina parvimacula sp. n., y otras diez especies: C. asunciana Strand, C. richardsoniae Schrottky, C. rotundiceps Smith, C. angulata sp. n., C. caveata sp. n., C. fimbriata sp. n., C. latisetis sp. n., C. subcarinata sp. n., C. tucumana sp. n. y C. umbricosta sp. n. Se designa lectotipo para C. asunciana Strand. Estas especies se caracterizan por una fuerte carena pronotal, como en los subgéneros Crewella Cockerell and Calloceratina Cockerell, pero se distinguen por tener una sola espina apical en las tibias anterior y media, y por la placa de cera restringida al segundo esterno metasomal. El nuevo subgénero se distribuye en la Argentina, Bolivia, Brasil, Paraguay, Perú y Uruguay.

              A revision of the bee genus Ceratina, subgenus Rhysoceratina (Hymenoptera, Apidae, Xylocopinae)

              The subgenus Rhysoceratina of Ceratina is restricted to South America, with known species in Argentina, Brazil, Colombia, Paraguay, and Uruguay. Nine species are recognized, four of which are described as new: C. canaliculata, C. pusilla, C. mendozina, and C. nitidifrons. Lectotypes are designated for C. catamarcensis Schrottky, 1907, and C. volitans Schrottky, 1907. A phylogenetic analysis supports the monophyly of the subgenus and, within it, of two major species groups. A key to the species, descriptions, distributional data, and illustrations are provided.
