Abstract
One new species of Neotropical Premnobius Eichhoff is described: P. brownei Atkinson & Flechtmann from Brazil. The presence of the related genus Premnophilus Browne is confirmed from South America and six new species are described: P. bertii Atkinson & Flechtmann from Brazil, P. jordali Petrov from Peru, P. maiai Atkinson & Flechtmann from Brazil, P. pedrosai Atkinson & Flechtmann from Brazil, P. sarahsmithae Atkinson & Flechtmann from Brazil and Trinidad and Tobago, and P. wilsoni Atkinson & Flechtmann from Brazil. French Guiana, and Peru. Gnathotrupes megapunctatus Bright, 2019 is recognized as a synonym of Premnobius perezdelacruceii Petrov & Atkinson, 2018. A synopsis of previously described Premnobius species and keys to species in both genera are presented. Generic characters for the three genera of Neotropical Ipini are discussed.
