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 ).
