Libellula bicolor Erichson, 1848: 583 . Type Material. Not examined. Diagnosis. Thorax, dorsum of abdomen, and basal spot on HW brown (female and sexually immature male); or thorax and abdominal S1-3 blue and abdominal S4-10 red (mature male). In females and sexually immature males, the dorsum of pterothorax is pale with dark antehumeral stripes and the central one is two or more times wider than lateral ones ( Fig. 15 ). Dark basal spot on HW does not reach the first antenodal vein or the AA vein, only extends to the penultimate row of cells of anal angle. Posterior lobe of vesica spermalis is not covered by the lateral lobe, which extends less posteriorly than the medial lobe ( Fig. 21 ). Hook is bilobed ( Fig. 18 ), fingerlike and not perpendicular to the longitudinal axis of vesica spermalis ( Fig. 21 ). Cornua is perpendicular to vesica spermalis transversal axis, with lobes separate at apex, and covered by lateral lobes in lateral view ( Fig. 21 ). Lab ≤ 30mm , LcaS4/LclS4 <2.1 ( Fig. 4 ).

Additional characters are provided by Costa and Pujol-Luz (1993) as follows: the cercus exceeds between 1/3 to half the length of epiproct, and there are eight palpal setae. Material Examined.

Larvae and adults of Erythemis peruviana inhabits ponds, swamps, backwaters of rivers, and rice field canals, where the period of greatest activity for the adults is from 10:00 to 16:00 hrs. The males perch on low vegetation branches or directly on the ground, folding their wings forward, changing perches constantly and showing intraspecific aggression, as well as interspecific aggression with males of E. vesiculosa and Erythrodiplax sp. (Palacino-Rodríguez and Millán 2010). Erythemis peruviana females have been observed perching or ovipositing over long periods in territories that are shared with non-territorial species such as Brachymesia furcata (Hagen) ( De Marco et al. 2005 ) .
