“…COMENTÁRIO -Somente duas espécies deste gênero eram conhecidas: Mielkeanthidium nigripes Urban, 1996, com escutelo preto e faixa amarela larga no tergo basal e M. rubripes Urban, 1996, com orla amarela no escutelo e faixas amarelas laterais no primeiro tergo, como em M. ornatum sp. nov., porém M. rubripes tem estria amarela muito curta no meio das paroculares, as axilas e o tergo distal pretos.…”

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. PANURGILLUS, A NEW GENUS OF PA NU RGINAE, WITII DESCRIPTI ON OF FOURTEEN SPECI ES FROM S OUTHERN BRA ZIL (HVMENO PTERA, A NDREN IDA E).PanurgilIus, a generic name used by J.S. Moure throughout various years in lill. as a substitue of Panllrginlls in the Neotropical Apifauna, is formally described. Ali specimens of lhe species here described were collecled during surveys of bees and melittophilous plants in th state ofRio Grande do Sul, southem Brazil. Various species of Panurgillus also occur in olher Slales of southern Brazil, in Argentina and probably in Uruguay, Paraguay and Eastern Bolivia. The bees are small (3,9-7,4 mm), black, with generally a few yellow paintings, two submarginal cells, lhe Isl m-cu dislanl to lhe base ofthe second submarginal cell, the clypeus nOI projected, lhe faci al foveae di slinct, scopa with simple, long hairs and lhe gonobase absent. Pa/lurgilllls vagabll/ldus Cockerell, 1918 is transferred to Pallurgillus as the type species and thirteen new species are described: P. eusliclus, P. jlavilarsis, P. jormosus, P. g uarilicola, P. hamalus, P. harlerae, P. holoSliclUS, P. malvacearum , P. mil/ulus , P. pe re~iae , P. plul11osulus, P. polilUS and P. reLiculalus. From some Slructures were took SEM photographs. KEY WORDS. Hymenoptera, Apoidea, Andrenidae, Panurginae, Pa/lurg il/us, bee systematics, southern Brazil Na região neotropical, a subfamília Panurginae é representada por mais de 20 gêneros (MICHENER 1979), mas em várias partes da América do Sul a apifauna aindaé pouco con h ecida. Levantamentos recentes de abe lh as e de plantas melitófilas no Estado do Rio Grande do S ul mostraram que existem muitas espécies de abelhas ainda não descri tas no sul do Brasi I
