Figure 4. Morphological variation in queens of the three species as defined by COI barcode groups.

Horizontal rows indicate species as identified by barcoding, whilst vertical columns show how molecularly identified specimens of each species can be morphologically identified as belonging to all 3 taxa. Specimens are identified by letters, which correspond to Table S1 as follows: a = T780, b = T773, c = T883, d = T875, e = T718, f = T787, g = T714, h = T713, i = T781.
