Protoneura peruviensis Fraser 1946: 459–460, figs. 5a–b (description of male, illustration of male S10); — Soukup (1954: 13; listed from Peru); — Rácenis (1959: 472; listed from Peru); — Kimmins (1966: 209; typecatalog); — Davies & Tobin (1984: 117; synonymic list); — Steinmann (1997: 453; synonymic list). Epipleoneura peruviensis Bridges(1994: VII.184; synonymic list); — Tsuda (2000: 12; synonymic list). Specimens examined.Total 4 ɗ, 2 Ψ. — Holotypeɗ, Peru, Loreto Department, Mishuyacu [near Iquitos] ( 03°51'S, 73°13'W), 0 2 vii 1930(BMNH); 1 ɗ, same data as holotypebut 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). Pterothoracic dorsum dark to upper 0.7 of metapleural suture in male ( Fig. 2l), to mid-height of metepisternum and with a black stripe along anterior margin of metapleural suture in female ( Fig. 2m). Apex of male genital ligula with a deep u-shaped cleft ( Fig. 19a) and latero-distal lobes short, broad, and curved medially ( Figs. 19b–c). Dorso-posterior margin of male S10 projected posteriorly ( Figs. 27g– 28g). Ventral branch of male cercus longer than base of cercus, approximately cylindrical ( Fig. 28g), in posterior view arising at mid-width and convergent to branch of opposite cercus at tip ( Fig. 30g). Paraproct pointed ( Fig. 28g). Ventral and dorsal sides of sub-basal plate of female ovipositor linear ( Fig. 36i).
Diagnosis.Male of D. peruviensisshares the ventral branch of cercus arising at mid-width and convergent to the branch of opposite cercus at tip only with D. flintiand D. muzoni( Fig. 30g); it differs from both by having the apex of genital ligula with a deep u-shaped cleft ( Fig. 19a), and further from D. muzoniby the ventral branch of male cercus being longer than the base of cercus ( Fig. 28g) and the absence of pale mesepisternal stripes ( Fig. 2l). Female is unique by the presence of a medio-ventral semicircular projection on posterior margin of pronotum ( Fig. 8) and by both ventral and dorsal sides of sub-basal plate of ovipositor linear ( Fig. 36i).
Biology.Adults were collected at streams and rivers.
Distribution.Loreto Department, Peru( Fig. 37).
