, because they agree with the type specimen in colouration of tergite 3. This preliminary solution is unsatisfactory, as colouration of the abdomen is variable in these intermediate specimens. Possibly, the intermediates represent a third species or even a species complex, but there are too few specimens available to make a decision on this. Another possibility is that

are the extreme ends of one highly variable species, but the fact that specimens from within one country (Suriname) can clearly be assigned to two different groups without significant character variation is here taken as a clue that this is not the case. The results of analyses of the barcodes of a few specimens do not shed light on this matter.
