“…Neste trabalho apresentamos: 1) a descrição de uma espécie nova, Anthidianum andicola sp. n., proveniente da Argentina, Jujuy, Tilcara; 2) a descrição do macho de Chrisanthidillm nigritllm Urban, 1997, também coletado na Argentina, Tilcara; 3) Anthidium bizonalum Friese, 1925, um novo sinônimo júnior de Anthidianum slIbpetiolatum (Schrottky, 1910). Os gêneros Chrisanthidium Urban, 1997 e Anthidianllm Michener, 1948 têm em comum, a ausência da carena entre a face anterior e a lateral dos mesepistemos.…”

The Anthidiini is a highly diverse tribe of bees with approximately 700 described species worldwide, of which about 350 occur in the Neotropical region. However, the phylogenetic relationships within the Neotropical lineage are poorly understood and the generic limits of these clades are still controversial, with different proposals of classification. Therefore, we carried out a phylogenetic study to investigate the monophyly of Neotropical taxa, to understand the relationships among Neotropical genera, and to propose a classification congruent with the evolution of the group. We performed parsimony-based morphological analyses using a matrix of 204 characters from adults of 83 species (79 terminal taxa of Anthidiini and four outgroup taxa). The results provide strong support for the monophyly of the tribe, despite a representation biased towards the Neotropical taxa. The monophyly of a large group containing only species from Neotropical genera is also supported. The latter group is divided into six main clades, one of them composed of only cleptoparasitic taxa (Austrostelis, Hoplostelis, Melostelis and Rhynostelis). The morphological characters assembled here allowed scrutiny of the genus-level classification of the Neotropical clade and may be useful for future phylogenetic studies involving the Anthidiini from other biogeographic regions.

ABSTRACT. Biology and ecology ofAnlflOdioctes moratoi Urban (Hymenoptera, Megachilidae, Anthidiini) in continuous forests and forest fragments in Central Amazonia, BraziJ. An/hodioc/es mora/oi Urban, 1999 was described based on specimens collecled in lhe slate of Amazonas during a study ofthe ecology oftrap-nesting bees and wasps. Sampling was done between 1988 and 1990 north ofManaus, in areas of the "Forest Fragment Biological Dynamics Project". Wooden lrap-nests were seI in dilTerent heights inside continuous forests, foresl ti'agmenls of differenl sizes, natural gaps inside continuous forest, and in c1eared areas between forest fragments. A total of61 nests were collected from which 33 males and 46 females emerged. The majority oI' nests was collected in continuous forests, at 15 m heighl, in holes 4.8 mm in diameter. No nest was collected in cleared areas. There was no correlation, neither belween number ofnests and monthly precipitation, nor belween the monlhly nllmber of nests constructed in the IWO conseclllive years. No nesl was conslructed belween JanllaJY and Jllne 1989. Overall, lhis coincided wilh lhe period ofleast activity ofother trap-nesting bees in the sllldieel areas. The nests consisted 01' a linear series 01' brooel cells with walls made ofresinolls materialmixeel with small wood chips. The average length of lhe provisioned cell was 13,4 mm. Half 01' lhis lenglh was occupied by a pollcn mass. The nlll11ber ofprovisioned cells varied between two and nine. In 52% 01' the nesls lhere was brood morlalily in aI least one cell. The phorid f1y Phalacr%-phol'O (Omapan/a) sp. was lhe only nest associale, emerged, Irom just one cell.
