Epipleoneura letitia Donnelly 1992: 73 –76, figs. 5.21–5.24 (description of male and female; illustration of male S10, base of Hw, female pronotum and mesostigmal plate); — Bridges (1994: VII.133; synonymic list); — Tsuda (2000: 12; synonymic list).

Specimens examined. Total 5 ɗ (paratypes), 1 Ψ (allotype). — Panama, Panamá Province: 1 Ψ, Pipeline road, 1.7–4.8 miles NW of Gamboa, 22 v 1970, leg. E. Morton (USNM); 1 ɗ, same data but 0 1 vii 1970, leg. E.S. Morton (TWD); 1 ɗ, same data but Río Frijoles, 23 I 1975, leg. M.L. May (MM); 1 ɗ, same data but Quebrada Juan Grande, 0 9 v 1975, leg. M.L. May (TWD); 2 ɗ, Limbo river at Limbo Hunt Club, near Pipeline Rd., 8 km NW of Gamboa (09°07'N, 79°42'W), 0 9 i 1977, leg. M.L. May (MM, RWG).

Characterization. Posterior prothoracic lobe smoothly convex in male, in female smoothly concave and lacking projections ( Fig. 5 View FIGURES 3 – 10 ). Pterothoracic dorsum dark to mid-height of metepisternum ( Figs. 2 View FIGURE 2 f–g), with a dark stripe on metapleural suture in male, and in juvenile specimens a narrow faint yellow humeral stripe. Apex of male genital ligula with a shallow v-shaped cleft ( Fig. 16 View FIGURES 13 – 20 a) and latero-distal lobes short, broad, and curved medially ( Fig. 16 View FIGURES 13 – 20 c). Dorso-posterior margin of male S10 projected posteriorly only slightly ( Figs. 27 View FIGURE 27 d–28d). Ventral branch of male cercus as long as base of cercus, approximately cylindrical ( Fig. 28 View FIGURE 28 d), in posterior view aligned with inner margin of cercus and diverging from opposite at tip ( Fig. 30 View FIGURE 30 d). Paraproct pointed ( Fig. 28 View FIGURE 28 d). Dorsal side of sub-basal plate of ovipositor slightly concave and ventral side slightly convex ( Fig. 36 View FIGURE 36 d).

Diagnosis. Male of D. letitia most closely approximates D. donnellyi ; both are diagnosed under the latter species. Male differs from D. flinti , D. muzoni , and D. peruviensis by the ventral branch of male cercus being aligned with cercus inner margin and diverging from the branch of opposite cercus at tip; from D. janirae by the ventral branch of cercus as long as base of cercus ( Fig. 28 View FIGURE 28 d) and postero-dorsal margin of S10 not or only slightly projected posteriorly ( Figs. 27 View FIGURE 27 d–28d), and from D. loutoni and D. tennesseni by its pointed paraproct. Female posterior lobe of pronotum of D. letitia lacks ventro-lateral processes as in D. flinti , but it is unique by its smoothly concave margin ( Fig. 5 View FIGURES 3 – 10 ). Drepanoneura letitia further differs from D. flinti by its quadrangular sub-basal plate of ovipositor (sb, Fig. 36 View FIGURE 36 d), which is acutely pointed (sb, Fig. 36 View FIGURE 36 c) in the latter. Biology. Adults are inconspicuous, fly close to quiet water on margins of wooded streams ( Donnelly 1992).
