41. Tetragonula (Tetragonula) pagdeni ( Schwarz, 1939) , Pagden’s Stingless Bee

This species is known in Singapore from a single nest found in an ornamental tree at Gardens by the Bay in 2016. It is well known in Thailand but not from the Sundaic region ( Sakagami, 1978; Rasmussen, 2008). Both the origins of this nest and establishment of the species in Singapore are unclear, but it may represent an anthropogenic introduction, as has been documented at this site for an anole ( Tan & Lim, 2012).
