Comments. The new records of B. ecuadorensis extend the geographic distribution of the species about 3000 km to the east. This species is now known to occur along the Amazonian region, from Sucumbios, Ecuador, to the east of Pará, Brazil ( Fig. 2 ). Bolivar ecuadorensis is morphologically very similar to B. helmuthi, which also was described from the Amazonian region, in southeast Colombia. These two species were found to have a considerable genetic distance for the Barcoding locus (11.8%) (Zaldívar-Riverón et al. 2013). However, the only consistent morphological differences between these two species are the colour of the first metasomal tergite (dark brown to black in B. ecuadorensis , entirely yellow in B. helmuthi) and the sculpture of the second metasomal tergite (entirely sculptured in B. ecuadorensis , only basally in B. helmuthi) (Zaldívar-Riverón et al. 2013).

The specimens from the Amazonian region mentioned above were assigned to B. ecuadorensis based on the presence of a yellow mesosoma and a second metasomal tergite entirely sculptured. However, these specimens have the first metasomal tergite mostly brown. Further morphological and molecular studies will therefore clarify whether B. ecuadorensis and B. helmuthi are conspecific.
