Diagnosis. Abdominal dorsum black or black and yellow, and with yellow spots in several segments. In some cases, the yellow color completely covering the dorsal region of the segment (F). Thorax and basal area on HW black; basal area on HW reaching the media posterior vein (MP) or beyond, covering a small basal region or the row of marginal cells to the anal angle (MRA, Fig. 26), and extending to the base of the triangle to the posterior region. Posterior extension of ventral teeth of male cercus about the same length as the apex of epiproct or less ( Fig. 13 View Figures 10–17 ). Posterior lobe of vesica spermalis covered by lateral lobe ( Fig. 19 View Figures 18–25 ), which extends more posteriorly than the medial lobe. Hook bilobed, triangular, and not perpendicular to the longitudinal axis of vesica spermalis ( Fig. 18 View Figures 18–25 ). Cornua parallel to the transversal axis of vesica spermalis ( Fig. 20 View Figures 18–25 ), with lobes separate apically, and covered by lateral lobes in lateral view. Vulvar lamina suboval with round posterior border ( Fig. 10 View Figures 10–17 ). Lab ≤ 30mm. LcaS4/lclS4 ratio>2.10; WmS2/LcaS5 ratio <3.

Larva. Thirteen preimaginal states were described by Rodrigues-Capítulo (1983) from Punta Indio and Los Talas (Buenos Aires, Argentina). Rodrigues-Capítulo (1983) described the last instar as follows: larvae greenish with a yellowish band on mid-dorsal region of the mesothorax surrounded by two brown spots, mask with whitish and brown irregular spots, seven meridional black and violet stripes on the eyes. Average total length 13.70 mm (live specimens) 15.90–16.50 mm (preserved specimens), this measurement differs from that of Klots (1932) who recorded between 14.50 and 15.00 mm. Head width 4.8–5.0 mm, head length 2.75 mm, head width-length ratio 1.78 mm, antenna length 1.92 mm and 4.60 mm respectively. Anterior, medial and posterior tibial length 2.9, 3.6 and 6.1 mm respectively. Mouth parts with thirteen to fourteen mental setae, small teeth on the distal region of the medial lobe of the mentum, eight to nine palpal setae, outer region of maxillary palp with numerous axial and lateral hairs. Mandibles with 4 + 1 incisive and three molar teeth. Lab 5.60 mm, superior caudal appendage 1.17 mm, lateral 0.67 mm and inferior 1.19 mm. According to Costa and Pujol-Luz (1993), the larva of E. attala bears twelve premental setae, and the cercus exceeds by 1/2 the length of the epiproct.

Remarks. Calvert (1928) provides data for larvae of this species, but he also warns of the potential for misidentification. This concern also is shared by Klots (1932) for the key she proposed for this species. Later Rodrigues-Capítulo (1983) redescribed the immature stages of E. plebeja clarifying the diagnostic characters proposed by the previous authors.

Biology. Larvae have been shown to dwell in a habitat where Azolla filiculoides Lam. and various species of Lemnaceae were present. Rodrigues-Capítulo (1983) described color variations in larvae, which vary depending on the substrate they use, and explains that rotifers, protozoans, oligochaetes, and filamentous algae are present due to the relative inactivity of the larva. There are reports of univoltine or semivoltine lifecycles with a facultative diapause that probably regulates the populations of both larvae and adults (Rodrigues-Capítulo 2000). Adults may be associated to ponds and lakes in forests, agricultural regions and sugar cane fields. E. attala perches on dead branches very close to the ground and it is common to find males of this species attacking those of E. plebeja (F. Palacino, pers. obs.).

Distribution. From U.S.A. to Argentina ( Fig. 29 View Figure 29 ), between 4–2000 m.asl. De Abenante and Philippi (1982) report E. attala from Uruguay, however, without indicating any locality.
