( Figs. 1–18 )

Diplosynapsis argentifascia Enderlein, 1914: 259 , fig. 5; Hull, 1962: 479; Martin & Papavero, 1970: 70; Lamas, 1972: 313; Artigas & Papavero, 1997: 70; Papavero, 2009: 17 (catalogue); Papavero, Artigas & Lamas, 2009: 27, figs. 71–75, 28, figs. 76–79. Erax argentiafascia ; Bromley, 1946: 114 (catalogue), error.

Diagnosis. Cells r1 and r2+3 wrinkled in the males ( Fig. 5 ); epandrium constricted apically ( Fig. 6 ); tergites 6 and 7 with shiny silvery apex ( Figs. 3, 4 ); gonocoxite apex rounded in lateral view ( Fig. 7 ); ejaculatory apodeme short, surpassing, at most, the level of the aedeagal sheath ( Fig. 8 ); aedeagus apex curved dorsally ( Fig. 8 ); ovipositor long and laterally compressed ( Figs. 10, 11 , 18 ); common duct of spermathecae short ( Fig. 17 ); expulsory ducts long ( Fig. 17 ); 3 spermathecae with oval capsules ( Figs. 14, 17 ); genital fork long ( Fig. 17 ).

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).
