Abstract

Barolineocerus Freytag, 2008 currently includes eleven species from Brazil, Colombia, Ecuador, French Guiana, and Peru, including three new species described herein, namely B. chicomendesi sp. nov. from Brazil (Amapá, Amazonas, Pará, and Roraima states) and French Guiana (Régina), B. dercyae sp. nov. from Brazil (Amazonas and Rondônia states) and Ecuador (Orellana), and B. digitatus sp. nov. from Brazil (Amapá) and French Guiana (Régina and Saül). In this revision, we propose a new synonymy for B. bispinus Freytag, 2008 (= B. declivus Freytag, 2008 syn. nov.), expand the known distribution of Barolineocerus to include Ecuador and record the following species from additional countries: B. acius Freytag, 2008, B. apiculus Freytag, 2008, B. elongatus Freytag, 2008, B. ornatus Freytag, 2008, and B. spinosus Freytag, 2008 from Brazil, B. acius, B. apiculus, and B. bispinus Freytag, 2008 from Ecuador, and B. bispinus from Peru.
