Cryptocerus spinosus Mayr, 1862: 761 (w.) BRAZIL. Neotropic.

Primary type information: Primary type material: lectotype worker (by designation of Kempf, 1951: 187). Primary type locality: lectotype Brazil: “Amazon River area” (no further data). Primary type depository: NHMW. Type notes: De Andrade & Baroni Urbani, 1999: 220, point out that the lectotype is labelled Pernambuco, and that there is a possible syntype soldier (NHMW), with the same data. But Mayr, 1862: 763, implies that he had only a single specimen, saying it is possible that “the ant just described (Cephalotes punctatus) is the soldier and the previous (Cephalotes spinosus) is the worker of one and the same species”.
