  title={Psaenythisca, a New Genus of Bees from South America (Apoidea: Andrenidae: Protandrenini) with a Description of the Nesting Biology and Immature Stages of One Species},
  author={Kelli dos Santos Ramos and Jerome G. Rozen},
ABSTRACT A new bee genus from Argentina, Psaenythisca, is described and includes three species: P. flavifrons (Vachal, 1909), n. comb, (originally described as Psaenythia), P. wagneri (Vachal, 1909), n. comb. (originally described as Psaenythia), and P. punctata (Urban, 2009), n. comb. (originally described as Anthrenoides). The new genus is proposed based on a comparative study of the Protandrenini lineages. Psaenythisca is closely related to Cephalurgus and Rhophitulus, and can be… 
Phylogenetic Relationships of a New Genus of Calliopsine Bees from Peru, with a Review of Spinoliella Ashmead (Hymenoptera: Andrenidae)
ABSTRACT We establish a new genus for an unusual species of Peruvian calliopsine bees (Panurginae: Calliopsini) that was initially reported in the literature as an undescribed species of Spinoliella
Taxonomy of the bee species Anthrenoides nigrinasis (Vachal, 1909) n. comb.: redescription of the type, description of the female, and new distribution records (Hymenoptera: Apoidea).
Protandrenini includes approximately 420 species of short-tongued bees, which are exclusively distributed in the Americas and many South American genera are in need of taxonomic revision.
New genera of meliturguline bees from Saudi Arabia and Persia, with notes on related genera and a key to the Arabian fauna (Hymenoptera: Andrenidae)
A new genus of melitturgine bees (Panurginae: Melitturgini) is described and figured from central Saudi Arabia, which may eventually warrant generic status once phylogenetic work on the tribe has been completed.
Nesting Biology and Immature Stages of the Panurgine Bee Genera Rhophitulus and Cephalurgus (Apoidea: Andrenidae: Protandrenini)
Nesting information on the communal ground-nesting Argentinian bees Rhophitulus xenopalpus Ramos and R. mimus Ramos is presented, which is compared with what is known concerning the closely related Brazilian bee Cephalurgus anomalus Moure and Lucas de Oliveira.
Hesperapis rhodocerata: Behavioral Biology, Egg, and Larval Instars, Including Behavioral and Larval Comparisons with H. larreae (Hymenoptera: Melittidae: Dasypodainae)
It is hypothesized that the clear thin transparent material covering the postdefecating larva of H. rhodocerata may function to inhibit desiccation and furthermore may be the same material that hardens and waterproofs the cell walls of other congeneric species including H. larreae, thereby serving a similar function but in a different way.
Phylogeny, biogeography and diversification of the mining bee family Andrenidae
It is found that diversification rates of Andrenidae steeply increased over the past 15 million years, particularly in the genera Andrena and Perdita, which suggests that these two groups and the brood parasites of the genus Nomada Scopoli are similar in age and represent the fastest diversifying lineages of all bees.


Taxonomic revision and phylogenetic relationships of the bee genus Parapsaenythia Friese (Hymenoptera, Apidae, Protandrenini), with biogeographic inferences for the South American Chacoan Subregion
The species of Parapsaenythia are revised, with seven species recognized, of which three are described as new, and a cladistic biogeographic analysis was performed, and area cladograms for the Chacoan subregion are presented and discussed.

Panurgillus gênero novo de Panurginae, com a descrição de quatorze espécies do sul do Brasil (hymenoptera, andrenidae)
The bees are small, black, with generally a few yellow paintings, two submarginal cells, the lst m-cu distant to the base of the second submarginals cell, the clypeus not projected, the facial foveae distinct, scopa with simple, long hairs and the gonobase absent.
Family-Group Names for Bees (Hymenoptera: Apoidea)
The name Anthophila, as proposed by Latreille, is adopted for the bees as a whole and the suggested current usage of all available family-group names is appended.
Espécies de Panurgillus Schlindwein & Moure (Hymenoptera, Andrenidae) depositados no Naturkunde Museum, Berlin
