ETYMOLOGY: The specific epithet is a matronym honoring the late Celia Díaz Díaz, mother of the senior author.
COMMENTS: Individuals of this species share features with both E. viridis and E. azurea , although the combination of characters observed diagnose them clearly as a distinct species. In terms of coloration, males (the only gender known) of E. celiae have cyan on areas that would be blue-purple in E. viridis , a more noticeable green coloration throughout, and narrower paraocular lines ( Figs. 29–31 View Figures 29–30 View Figures 31–37 ). Puncture density on the mesepisternum is comparable to E. azurea . The mesotibial anterior tuft in E. celiae is intermediate when compared to E. viridis and E. azurea , and it is distinguishable by having a mid-width comparable to that of the contiguous velvety area ( Fig. 146 View Figures 144–154 ), while in the other two species the contiguous velvety area is either noticeably narrower ( Fig. 144 View Figures 144–154 ) or wider ( Fig. 145 View Figures 144–154 ). The species is known at present from only a few specimens from the western areas of the Amazon Basin in Colombia, Ecuador, and Peru ( Fig. 170 View Figure 170 ), although it must certainly occur in nearby areas of Brazil.
