“…Moure (1950) proposed four genera (Celetrigona Moure, Dolichotrigona Moure, Leurotrigona Moure, and Trigonisca) for the more than 45 species that later Michener (2007) synonymized under the genus Trigo¬ nisca. Pedro (2005, 2009), Albuquerque and Camargo (2007), and Pedro and Camargo (2009) revised the majority of the species in these four groups, although those in Trigonisca s.str., the most species rich of the four, remain to be explored. Despite morphological differences among groups, Michener (2007) did not recognize them at the subgeneric nor generic level, as he did for many other neotropical meliponines.…”

Stingless bees (Apinae: Corbiculata: Meliponini) are biologically and culturally impor¬ tant pollinators within the tropical and subtropical areas of the world. However, limited information is available for the majority of the species. Biological and systematic data are presented for a new species of Trigonisca Moure, from the arid region of La Guajira, Colombia. The genus is part of the distinctive Trigonisca genus group, noteworthy for its position as the earliest diverging extant lineage of neotropical stingless bees. We briefly diagnose the genus group and provide a key to the genera and subgenera of the Trigonisca genus group, along with the description of Exochotrigona Engel, new subgenus. We also outline the species occurring in Colombia and present a description for Trigonisca (Trigo¬ nisca) mepecheu Engel and Gonzalez, new species, including accounts of all three castes. A single, poorly preserved egg is noteworthy because of its extremely small size. Its chorion

Dioecious Clusia nemorosa achieves pollination by combining specialized and generalized floral rewards

Plants often combine multiple strategies to achieve pollen transfer. The dioecious Clusia nemorosa (Clusiaceae) produces floral resin, a specialized reward for resin-collecting bees. It also exhibits floral automimicry with female flowers mimicking male flowers in order to attract pollencollecting insects. We observed the hourly visitation frequency and behaviour of bee visitors on two rock savanna sites in French Guiana. The major strategy in pollen transfer and the variation in visitation rates among visitor species were examined. We hypothesized that the visitation rate will vary between the floral sexes and degree of this variation will differ between the two-reward systems. We found no evidence for visits being exclusively related to resin collection, which we expected to be the principal strategy in pollen transfer. Deceit pollination appeared to have minor importance and seemed to be locally associated with the site, where demand for pollen was greater. Flower visits that probably facilitated most pollen transfer, combined resin and pollen. The pollinators involved in this system collected pollen from male flowers and resin from female flowers. The fruit set was not particularly low (44.19%) so offering different rewards by different flower genders has not constrained reproductive success in this system. Pronounced variation in visitation rates between sexes was not related to the pollination mechanisms but to the demand for the two rewards. Overall demand for pollen was greater than demand for resin. Female flowers were visited much less frequently than male flowers. Peak pollen collection occurred in the morning, i.e., as soon as the resource was available, while resin was collected throughout the day. There was a local variability in demand for the two resources because both the visitation rate and the behaviour of foraging bees varied between the two observation sites.
