Rhopalothrix plaumanni Brown & Kempf, 1960: 235 , fig. 58. Holotype, worker: Brazil, Santa Catarina: Nova Teutônia (F. Plaumann) [MZSP, paratype worker at MCZC] (not examined).

Rhopalothrix acutipilis Kempf, 1962: 28 , fig. 28. Holotype, queen: Brazil, Santa Catarina: Nova Teutônia, V-1960 (F. Plaumann) (not examined). New Synonymy.

Comments. In this study queens were associated with workers for three Central American species. The queens differed from the workers in pilosity and the shape of the face. The queens bore numerous short bristles, which are lacking on the workers, and the worker faces had much stronger grooves and gibbosities. The characteristics of the mandible and labrum were shared between queens and workers. Examination of the figures for R. plaumanni and R. acutipilis , the types of which are from the same locality and by the same collector, suggest that R. acutipilis is the queen of R. plaumanni .
