Oxyallagma dissidens is a species of high elevations 2600-2700m in Ecuador and Peru. The larva of Oxyallagma dissidens was hitherto unknown. Based on exuviae of reared specimens, the final instar larva of Oxyallagma dissidens is described. Exuviae of Oxyallagma dissidens have two parallel rows of dark spots on the dorsum of the abdomen, the prementum has 5-6 setae and the labial palps 6 setae. Antenna 7-segmented, distal margin of labial palp with four crenulations and a large spine. Head brownish and between the eyes at the front with a light band with three loops to behind. Pterothorax with parallel stripes on the wing bags at the inner side. Metathoracic femur length 2.75 mm. All femora with four darker edges with fine spines. Abdominal dorsum with fine punctuations and with a darker brownish distal half. Oxyallagma dissidens has a comparable strong armation on the femurs. The gill lamellae have a medial broad dark brown vein, with several veins at all sides to the border of gills. In one case a description on Oxyallagma dissidens was not given, but a figure was published. Oxyallagma dissidens was mentioned from Peru (Quito, La Granadilla) and from Ecuador (Lago San Pablo, Campos of Guayaquil). Oxyallagma dissidens is the recent name in contrast to the alternative name runtuni. Bota-Sierra and Andrés described Oxyallagma colombianum as new species of the genus from Colombia.
