Cryptocerus (Cyathocephalus) prodigiosus Santschi, 1921h: 124 (s.q.) ARGENTINA (Santiago del Estero). Neotropic.

Primary type information: Primary type material: 2 syntype soldiers, 2 syntype queens. Primary type localities: 1 soldier, 1 queen Argentina: Santiago del Estero, banks of Río Salado, vic. Icaño (E.R. Wagner); 1 soldier, 1 queen Argentina: Santiago del Estero, Río Dulce (E. Le Moult). Primary type depositories: MNHN, NHMB. Type notes: De Andrade & Baroni Urbani, 1999: 675, report that the lectotype soldier designated by Kempf, 1964b: 252 (in NHMB) cannot be found. Perhaps it was never labelled because De Andrade & Baroni Urbani, 1999: 677, report 2 soldiers, 1 queen as examined syntypes. Material is therefore all retained here as syntypes.
