Specimens examined. Total 4 ɗ, 2 Ψ. — Holotype ɗ, Peru, Loreto Department, Mishuyacu [near Iquitos] (03°51'S, 73°13'W), 0 2 vii 1930 (BMNH); 1 ɗ, same data as holotype but Río Amazonas, Iquitos, ix 1938, leg. G.G. Klug (RWG); 2 ɗ, same data but i/ iv 1940 (RWG); 2 Ψ, same data but vi 1939 (RWG).

Characterization. Posterior prothoracic lobe smoothly convex in male, with a wide and short semicircular medio-ventral projection in female ( Fig. 8 View FIGURES 3 – 10 ). Pterothoracic dorsum dark to upper 0.7 of metapleural suture in male ( Fig. 2 View FIGURE 2 l), to mid-height of metepisternum and with a black stripe along anterior margin of metapleural suture in female ( Fig. 2 View FIGURE 2 m). Apex of male genital ligula with a deep u-shaped cleft ( Fig. 19 View FIGURES 13 – 20 a) and latero-distal lobes short, broad, and curved medially ( Figs. 19 View FIGURES 13 – 20 b–c). Dorso-posterior margin of male S10 projected posteriorly ( Figs. 27 View FIGURE 27 g– 28g). Ventral branch of male cercus longer than base of cercus, approximately cylindrical ( Fig. 28 View FIGURE 28 g), in posterior view arising at mid-width and convergent to branch of opposite cercus at tip ( Fig. 30 View FIGURE 30 g). Paraproct pointed ( Fig. 28 View FIGURE 28 g). Ventral and dorsal sides of sub-basal plate of female ovipositor linear ( Fig. 36 View FIGURE 36 i).

Diagnosis. Male of D. peruviensis shares the ventral branch of cercus arising at mid-width and convergent to the branch of opposite cercus at tip only with D. flinti and D. muzoni ( Fig. 30 View FIGURE 30 g); it differs from both by having the apex of genital ligula with a deep u-shaped cleft ( Fig. 19 View FIGURES 13 – 20 a), and further from D. muzoni by the ventral branch of male cercus being longer than the base of cercus ( Fig. 28 View FIGURE 28 g) and the absence of pale mesepisternal stripes ( Fig. 2 View FIGURE 2 l). Female is unique by the presence of a medio-ventral semicircular projection on posterior margin of pronotum ( Fig. 8 View FIGURES 3 – 10 ) and by both ventral and dorsal sides of sub-basal plate of ovipositor linear ( Fig. 36 View FIGURE 36 i).
