From the introduction:
"The present work includes a revision of the world species of the Isotima complex, the taxonomy of which is in a state of confusion. Lack of properly conducted surveys and the absence of research material and identification manuals in the past slwoed down new research and also prevented the easy finding and understanding of the facts already known. The present work was, therefore, undertaken with a view to revise a group of genera of the tribe Goryphini, subtribe Goryphina."
