Quote from page 187: "The records of this species appear to indicate that it is confined to the main Gunnison and the larger tributaries. It is probably more abundant than the records show because the river was not worked with the intensity that the streams were, mainly because of its inaccessibility."

Quote from page 267: "This genus and Attenella have been placed in a separate subtribe Timpanogae by Allen (1984). They are distinguished by larvae with gills only on abdominal segments 4-7. All other Colorado ephemerellids are members of the Ephemerellae (gill on segments 3-7). Timpanoga hecuba was divided into two subspecies by Allen and Edmunds (1959), with T. hecuba pacifica restricted in distribution to the Pacific coast region, and T. hecuba hecuba found variously throughout the Intermountain West.
