The present study provides a comprehensive review of cytogenetic data on Meliponini and
their chromosomal evolution. The compiled data show that only 104 species of stingless …

Plebeia is a taxonomically complex genus of stingless bees characterized by remarkable
interspecific morphological similarity. On the other hand, cytogenetic data have been useful …

Tetragonisca angustula and Tetragonisca fiebrigi have recently been listed as valid species.
This study aimed to cytogenetically investigate both species, emphasizing the new registry …

The origin of supernumerary (B) chromosomes is still a debated topic, with intra-and
interspecific origins being the most plausible options. In the bee Partamona helleri, a …

Studies in several organisms have contributed to the understanding of heterochromatin and
its biological importance. In bees of the tribe Meliponini, the presence of chromosomes with …

Cytogenetic data for the genus Acromyrmex Mayr, 1865 are available, to date, for a few
species from Brazil and Uruguay, which have uniform chromosome numbers (2n= 38). The …

The stingless bee Partamona helleri in southeast Brazil shows the regular chromosome
number 2n= 34 and a variable number of up to four minute B1 or B2 chromosomes. Previous …

Stingless bees are distributed widely in the tropics, where they are major pollinators of
several plant species. In this study, the karyotype of Meliponaquinquefasciata Lepeletier …

The stingless bee Partamona helleri (Meliponini) is distributed across the Atlantic rainforest
biome in Brazil. Cytogenetic studies on P. helleri have shown a conserved diploid number …

Partamona helleri from southeastern Brazil has shown the presence of up to four minute
supernumerary chromosomes of the B1 or B2 type and a numeric variation from 2n= 34 to …
