N2  - The "pollens" group of Cerceris is established for C. furcifera Schletterer (Paraguay), C. mariusi sp. n. (Paraguay), C. nigrosa sp. n. (Argentina), C. pollens Schletterer (Argentina and Paraguay), C. serrana sp. n. (Argentina), and C. willineri Fritz (Argentina), and the "rugulosa" group for C. rugulosa Schrottky (Argentina). A key to the species of the "pollens" group is included. The subspecies Cerceris r. dismorphia Schrottky is not regarded as valid.
