Etymology. We name this species flinti (noun in the genitive case) in honor of our friend and colleague Oliver Flint Jr. in recognition of his contributions to the knowledge of New World Odonata and his ongoing kind assistance to odonate students as curator of the rich USNM collection.

Specimens examined. Total 8 ɗ, 1 Ψ.— Holotype ɗ: Colombia, Amazonas Department, Puerto Abeja, Stream #3, N of Araracuara (00°04'44''S, 72°26'50''W), 0 3 vii 1996, leg. G. Pritchard & J. Zloty (USNM). Paratypes: 1 ɗ, same data as holotype (USNM); 6 ɗ, 1 Ψ, same data (RWG).

Male holotype. Head. Labium, ventral third of labrum, anteclypeus, and triangular spot on anterior surface of antennifer pale yellow; base of mandibles, genae, and ventral half of antefrons pale blue, remainder of head black.

Thorax. Prothorax, mesepisternum, mesepimeron, and portion of metepisternum posterior to metastigma black with metallic green and copper reflections; portion of metepisternum anterior to metastigma, metepimeron, and pterothoracic venter pale yellow ( Fig. 2 View FIGURE 2 c); coxae blackish; trochanters yellow; femora brown to black at apex; tibiae, tarsi, and pretarsi yellow with black apices; 3 spurs on metafemora, 6 on metatibiae. Hw 5.5 times as long as wide; 12 Px in Fw, 10 Px in Hw; MP reaching wing margin at vein descending from subnodus; IR2 arising just distal to vein descending from subnodus; IR2 and RP 3 in contact one cell posterior to their origin; RP 2 beginning closer to Px 5 in Fw and to Px 3 in Hw; pt pale brown with yellow marginal hairline, shorter than underlying cell in Fw and as long as underlying cell in Hw, with costal side as long as posterior side.

Abdomen. Dorso-laterally black with metallic reflections, latero-ventral portion of terga and sterna pale brown to yellow. Apex of genital ligula with a shallow v-shaped cleft ( Fig. 14 View FIGURES 13 – 20 a) and latero-distal lobes short, broad, and curved medially ( Fig. 14 View FIGURES 13 – 20 c). Dorso-posterior margin of S10 projected posteriorly ( Figs. 27 View FIGURE 27 b–28b). Ventral branch of cercus longer than its base, approximately cylindrical ( Fig. 28 View FIGURE 28 b), in posterior view arising at mid-width of cercus and convergent to branch of opposite cercus at tip ( Fig. 30 View FIGURE 30 b). Paraproct pointed ( Fig. 28 View FIGURE 28 b).

Dimensions. Total length 29.9 mm; abdomen length 25.5 mm; Hw 16.4 mm.

Paratypes. Paratypes are similar to holotype but vary as follows: femora banded to entirely dark brown; 4–5 spurs on metafemora, 5–6 on metatibiae; Hw 5.6–5.8 times as long as wide; 11–13 Px in Fw, 9–11 Px in Hw; MP reaching wing margin from slightly distal to vein descending from subnodus to distally for 1/4–1/3 of length of adjacent cell, and IR2 sometimes arising at vein descending from subnodus. Females have the ventral fourth of labrum yellow, dark color of thoracic dorsum extending to metapleural suture only at posterior fifth ( Fig. 2 View FIGURE 2 d), femora yellow with two black bands, posterior margin of female pronotum approximately linear ( Fig. 4 View FIGURES 3 – 10 ), and dorsal and ventral sides of sub-basal plate of ovipositor concave ( Fig. 36 View FIGURE 36 c).

Dimensions. Males (n = 7): total length 29.9–31.1 mm [mean 30.5 mm; SD 0.5]; abdomen 25.4–27.4 mm [mean 26.1 mm; SD 0.6]; Hw 16.4–17.6 mm [mean 16.8 mm; SD 0.5]. Female (n = 1): total length 29.6 mm; abdomen 24.9 mm; Hw 17.1 mm.

Diagnosis. Male differs from D. peruviensis only by morphology of its genital ligula. Male shares cercus with ventral branch arising at mid-width and parallel to branch of opposite cercus only with D. muzoni and D. peruviensis ( Fig. 30 View FIGURE 30 b), but it differs from the former by its ventral branch of cercus longer than base of cercus ( Fig. 28 View FIGURE 28 b), and from both species by its apex of genital ligula with a shallow v-shaped cleft ( Fig. 14 View FIGURES 13 – 20 a). Female is unique in having the posterior lobe of pronotum approximately linear and devoid of ventro-lateral processes ( Fig. 4 View FIGURES 3 – 10 ) and by the sub-basal plate of ovipositor with both ventral and dorsal sides concave ( Fig. 36 View FIGURE 36 c).
