Resumo: Study of recently collected larvae of two species of Ischyomius Chevrolat, 1871 from Napo and Pichincha, Ecuador, tentatively identified as I. denticollis Champion, 1916 and I. singularis Chevrolat, 1871 confirm the classification of the genus Ischyomius within the family Pythidae. Salient larval characters which solidify this placement are: 5 stemmata arranged into an anterior column of 3 and posterior column of 2, parabasal ridges along anterior margins of abdominal tergites, prominent urogomphi with inner urogomphal teeth and various dorsal tubercles, and transverse row of dentiform asperities along anterior margin of sternite 9. Important features of the larva are illustrated with photographs. A key to larvae of world genera of Pythidae is provided as well as natural history information on Ischyomius.
