The first cases of gynandromorphism in oil‑collecting bees (Hymenoptera, Apidae: Centridini, Tapinotaspidini)
- Leopoldo J. Álvarez, W. P. Silva, Mariano Lucia, Antônio J C Aguiar
- BiologyPapéis Avulsos de Zoologia

Described gynandromorphs of two species oil-collecting bees: Lophopedia nigrispinis and Epicharis iheringii, both with partial bilateral phenotypic asymmetry, both of which have a female phenotype predominantly on mesosoma and metasoma.
Amazonian species within the Cerrado savanna: new records and potential distribution for Aglae caerulea (Apidae: Euglossini)
- D. P. Silva, Antônio J C Aguiar, G. A. Melo, Evandson J. Anjos-Silva, Paulo Jr. Marco
- 20 June 2013
A. caerulea distribution significantly increased towards the Cerrado according to both MaxEnt and GARP algorithms, which are important dispersal alternatives for several species dwelling the Amazon and the Atlantic forest.
Nesting Biologies and Immature Stages of the Tapinotaspidine Bee Genera Monoeca and Lanthanomelissa and of Their Osirine Cleptoparasites Protosiris and Parepeolus (Hymenoptera: Apidae: Apinae)
Abstract The nesting biologies of Monoeca haemorrhoidalis (Smith) and Lanthanomelissa betinae Urban (Tapinotaspidini) are described from southeastern Brazil. Both are ground nesting; the nests of the…
A perfume-collecting male oil bee? Evidences of a novel pollination system involving Anthurium acutifolium (Araceae) and Paratetrapedia chocoensis (Apidae, Tapinotaspidini)
This pollination system involving male Paratetrapedia oil bees and the tropical herb Anthurium acutifolium bears a remarkable resemblence with the interactions between perfume-collecting male euglossine bees and their preferred flowers, discovered by Stefan Vogel half a century ago.
Interaction between oil-collecting bees and seven species of Plantaginaceae
The new records of Tapinotaspidini and Centridini species acting as specialized pollinators of Plantaginaceae suggest that there is a geographic variation in the pollinator of the same plant species, and that the evolutionary scenario of the historical relationships between oil-collecting bees and floral oil producing plants is more complex than previously considered.
Revision and phylogeny of the bee genus Paratetrapedia Moure, with description of a new genus from the Andean Cordillera (Hymenoptera, Apidae, Tapinotaspidini)
A comprehensive study was carried out to review the taxonomy of the genus Paratetrapedia and to investigate cladistically the relationships amongst its species.
Floral oil collection by male Tetrapedia bees (Hymenoptera: Apidae: Tetrapediini)
Report of floral oil collection by males of Tetrapedia, a Neotropical genus of oil-collecting bees, describes behavioral aspects of oil foraging by males, data on morphological structures associated with the collection of this resource are presented, and potential hypotheses to explain the significance of floral oils in the mating system of tetrapedia are discussed.
Krameria tomentosa oil flowers and their pollinators: Bees specialized on trichome elaiophores exploit its epithelial oil glands
- L. Carneiro, Antônio J C Aguiar, C. Martins, I. C. Machado, I. Alves-dos-Santos
- 1 August 2015
The diversity of bee visitors suggests that pollen-collecting bees also play an important role in the maintenance of K. tomentosa pollination, and it is presumed that the association between the morphology of the oil- Collecting apparatus and the elaiophore type is not enough to predict relationships in oil-systems.
Notes on oil sources for the bee genus Caenonomada(Hymenoptera, Apidae, Tapinotaspidini)
The record of Caenonomada on Plantaginaceae suggests the use of trichomatic oil glands as a primitive condition in the tribe Tapinotaspidini.
Taxonomic revision of the bee genus Lophopedia Michener and Moure (Hymenoptera, Apidae, Tapinotaspidini)
- Antônio J C Aguiar
- 10 August 2009
The genus Lophopedia is taxonomically revised, including five new species, including three new synonymies, which are associated with forested areas, except for one species, L. savanicola, which is endemic to the Cerrado savanna.
