    Abstract The present study provides evidence of primitively eusocial behavior in Augochlora amphitrite (Schrottky). Bees were reared in laboratory nests and observed throughout their nesting cycle. Introduced foundresses constructed nests solitarily, but upon the emergence of the first daughter their activities changed drastically, marking the onset of a social phase. The colonies presented two well defined female castes according to their physiology, size and behavior. Foundresses monopolized oviposition, displayed low rates of nest construction, guarding, and pollen collection, they were the individuals that initiated social interactions, and were statistically larger. Daughter bees were smaller, with undeveloped ovaries, performed most tasks at the nest and were the subordinate individuals in social interactions.

    Abstract Two new species of Melitoma Lepeletier and Serville are described: M. fulviscopis n. sp. from Matto Grosso, Brazil, and M. torquata n. sp. from southeastern and southern Brazil, and northern Argentina. The males have a peculiar hind basitarsus, unique among emphorine bees, that suggests a close relationship of the two species. The basitarsus bears, on the inner surface, a longitudinal channel-like polished depression fringed with long hairs. Se describen dos nuevas especies de Melitoma Lepeletier y Serville: M. fulviscopis n. sp. de Matto Grosso, Brasil, y M. torquata n. sp. del sudeste y sur de Brasil, y norte de la Argentina. Los machos presentan un particular basitarso posterior, único entre las abejas emphorinas, que sugiere un estrecho parentesco entre ambas especies. El basitarso tiene en la cara interna una depresión lisa en forma de canal longitudinal, bordeada de largos pelos.

    Abstract A revision of the bee genus Nomada Scopoli in Argentina is presented. Nine species are recognized in this region, five of which are described as new: N. mesopotamica, N. longula, N. chacoana, N. missionica, and N. turrigera. Lectotypes are designated for N. pampicola Holmberg, 1886, and N. costalis Brèthes, 1909. A new name, N. holmbergiana, is proposed for Hypochrotaenia parvula Holmberg, 1886, preoccupied in Nomada, and a neotype is designated for H. parvula Holmberg. A key to the species, descriptions, distributional data, and illustrations are provided. Se presenta una revisión de las abejas del género Nomada Scopoli en la Argentina.

    Abstract The nesting biology of Augochlora (Augochlora) amphitrite (Schrottky) in a natural reserve in the Province of Buenos Aires, Argentina, is described. The species nests in decaying wood. Two types of nest architecture were found, which differed according to the substrate where they were built, either soft or hard wood. Nests in soft wood had the cells grouped in clusters surrounded by a cavity, and the clusters were supported by a varying number of pillars. Nests constructed in decomposing portions of cracks in otherwise hard wood had the cells constructed against the walls, without any pillars or surrounding cavity. Cells of both types of nests were oriented in all directions, without any detectable pattern. Measurements and characteristics of the nests are tabulated and compared to those known for other species of Augochlora s. str. Behavioral observations of active nests are indicative of a social division of tasks in A. amphitrite. Such observations include nests with several females, some of which were never observed outside the nests, females with different degrees of wear and of ovary development, and at least one female that actively collected pollen which had much worn mandibles and wings, and undeveloped ovaries, all characteristics of the worker caste in social halictids.
