Allodapini

Allodape Allodapula Braunsapis Brevineura Compsomelissa Effractapis Eucondylops Exoneura Exoneurella Exoneuridia Halterapis Hasinamelissa Inquilina Macrogalea Nasutapis The Allodapini is a tribe of bees in the subfamily Xylocopinae, family Apidae.

[2] Many of the species in the tribe form small social colonies where a group of females cooperatively care for the developing larvae.

The larvae of allodapine bees are remarkable in their complex morphology, and in most species they possess appendages, tubercles and long setae.

[10] However, molecular phylogenetic studies show that social living is ancestral for the tribe as a whole and has been in place for about 50 million years.

The preponderance of female-biased sex ratios in allodapine bees is thought to be due to the benefits of sisters cooperating with each other and involves a theory known as local resource enhancement.

Conservation concerns centre on two regions: (i) large-scale habitat loss in Madagascar poses a major threat to that island's unique bee fauna, including allodapine bees, many of which are still to be scientifically described;[20] and (ii) the Australian region is likely to contain many undescribed socially parasitic species[21] which are threatened because of their very small populations sizes.
