Type species Notoperla fuegiana (Enderlein 1905)

Illies (1958) described Abranchioperla archiplatae from larvae only and proposed the genus Abranchioperla and the family Abranchioperlidae to contain the species Abranchioperla archiplatae. He based the generic and family name on the lack of anal gill filaments in larvae and chose as the holotype a larva from a mountain stream at 2000m by Lo Valdés near Santiago, Chile (33 ° 45´00’’ S).

Illies (1960) gave a diagnosis for Abranchioperlidae, described and illustrated the female of Abranchioperla archiplatae from a female from Rio Murta which flows into Lago Buenos Aires (46 ° 30’ 00’’ S) and illustrated a larva from Rio San Ricardo in Tierra del Fuego. In 1963 Illies revised Notoperla and declared Abranchioperla a new synonym. He also stated that his 1960 A. archiplatae larval illustration was that of the larva of Notoperla fuegiana and that the female he described was a N. tunelina female. He then invalidly designated as holotype of Notoperla archiplatae a male from Las Trancas, Cordillero Nuble, Chile (36 ° 56´00’’ S) and the previous holotype larva as a paratype. For the 3 species known at that stage he supplied a distribution map showing Notoperla fuegiana restricted to Tierra del Fuego; N. tunelina from Patagonia to Chiloe Island and N. archiplatae above there to about level with Santiago.

Illies (1963) is still the authority on Notoperla but should be used carefully for 3 reasons. There is still insufficient information on the known species, there may be other undescribed species and the distribution map may not show the true distribution of the species.
