Diagnosis.
Thorax, dorsum of abdomen, and basal area on HW brown or reddish-brown (male) or S1-3 brown-greenish with darker brown spots, S4-7 pale brown with dark brown spots on dorsal and lateral regions, S8-10 dark brown in the dorsal and lateral regions, ventral region with greenish spots (female). Dark basal spot on HW reaching the following regions: first antenodal vein, beyond the MP crossvein, the penultimate (pra, Fig. 26) or the entire row of marginal cells, at least to the AA or most of the base of the triangle. Posterior extension of ventral teeth on male cercus about to the same level as the apex of epiproct or less (
Fig. 13
). Posterior lobe of vesica spermalis not covered by lateral lobe (
Fig. 21
), which extends more posteriorly than medial lobe. Hook bilobed, rectangular (
Fig. 25
), and not perpendicular to the longitudinal axis of the vesica spermalis (
Fig. 18
). Cornua perpendicular to the transversal axis of vesica spermalis, with lobes separated to apex, and covered by lateral lobes in lateral view (
Fig. 19
). Vulvar lamina suboval with round posterior border (
Fig. 10
). Lab ≤
30mm
, lcaS4/ lclS4 <2.10; WmS2/LcaS5 <3.

Biology.
This species inhabits ponds, marshes and lakes, where major of males constantly change perches, but keep sites very close to water (F. Palacino, pers. obs.).
E. carmelita
is commonly found on sunny days between 10:00 and 15:00 hours, when they perch, fly quickly around their territories, copulate and lay eggs. Males are territorial and display continuous intra and interspecific aggression.
Larva.
Unknown.
