Comments. Diplosynapsis argentifascia was described based in 6 specimens from Peru (Cuzco, Junin) and Brazil (Pará). Enderlein (1914) deposited the specimens in the Stettiner Zoologisches Museum ( Alemanha) . According to Papavero (2009) the syntypes are deposited in the Instytut Zoologiczny Polskiej Akademii Nauk (IZPAN), Warsaw, Poland . According to the IZPAN curator (Thomas Huflejt 2012, in litt.), 2 syntypes with red labels were loaned to the National Museum of Natural History, London, (NHM) and they have not been returned yet, and four specimens with yellow labels, labeled as ‘cotypes’, are deposited at IZPAN (Figs. 1–4; 10–12). A loan request was sent to the IZPAN curator to study part of the syntypes, but the request was denied due to the institute’s policy. Nonetheless, photographs of these specimens were arranged for this study.

Distribution. Peru (Cuzco, Junín); Brazil (Pará) (Fig. 75).
