New Neotropical Trichoptera: Banyallarga and Phylloicus species delineation by revisited paraproct (Calamoceratidae)

Abstract

We have revised the theory of the condensed complexity of the simple by incremental subtraction to understand the apparently vestigial character state of the simplified paraproct, especially pronounced at the Banyallarga and Phylloicus genera in the Calamoceratidae family. We have recorded Leptonema album Mosely, 1933 and Leptonema intermedium Mosely, 1933 from Ecuador, and Leptonema spirillum Flint, McAlpine & Ross, 1987 from Colombia, as well as described six new species: Banyallarga (Histricoverpa) isidra sp. nov., Banyallarga (Histricoverpa) taraja sp. nov., Banyallarga (Histricoverpa) tinalandia sp. nov., Phylloicus sarlos sp. nov., Oecetis tina sp. nov. in the Oecetis avara species group and Helicopsyche (Cochliopsyche) nyurga sp. nov.
