Luederwaldt (1923) described Pinotus fortepuctatus  (original designation) for Equador [= Ecuador, Bucay west]. Subsequently, Pereira (1953) considered this species as a synonym of Dichotomius globulus  [= Pinotus globulus  original designation, described by Felsche in 1901, with type locality Amazonas]; according to Pereira, the two species have the same morphological characteristics. However, upon examining the external morphology (specifically, the depressions of the pronotal disc and elytral microsculpture) of the type specimens, P. fortepuctatus  (lectotype ♂ here designated, deposited at the MZUSP, Plate 57C) and P. globulus  (lectotype ♂ here designated, deposited at the SMTD, Plate 57D), we could confirm they belong to distinct species. Therefore, maintaining the specific name originally proposed by Luederwaldt, we elevate it to species level under the following status: Dichotomius (Luederwaltinia) fortepunctatus  (Luederwaldt, 1923) revalidated name. Two lectotypes (♂, with localities Bucay and Iquitos) are here designated and illustrated (Plate 57C, D).
