Key to Paratopula species
This worker key is based on Luo and Guénard, 2016.
There are 12 described species of Paratopula. Workers are known for 8 species, with the remaining 4 only known from sexual forms.
Luo and Guénard noted: The key to global Paratopula species is modified and updated based on the keys and species descriptions provided in Bolton (1988), Sheela & Narendran (2008) and Xu & Xu (2011).
