Abstract
Twenty-four new species of Parasigmoidella from Papua New Guinea (14 species), Irian Jaya (six species), and the Philippine Islands (four species), are described. Lupparia inconspicua Shelford (Papua New Guinea) and Theganopteryx reticulata Bolívar (Seychelles) are transferred to Parasigmoidella, making a total of 35 species worldwide. A key to the known males of 34 species is presented.
