Remarks. Galileo & Martins (2009) described Bisaltes (Bisaltes) petilus based on males and females from Costa Rica. They compared their new species with B. (B.) buquetii , B. (B.) fuchsi (currently in synonymy with B. (B.) buquetii ), and B. (B.) fuscoapicalis Breuning, 1950 . Although B. (B.) petilus is quite similar to these species, especially the former, it was not compared with B. (B.) pulvereus . Comparing the original descriptions of Esthlogena pulverea and B. (B.) posticalis with that of B. (B.) petilus , as well as photographs of the two former species with the holotype of the latter, we cannot find a reliable difference. The general color of the pubescence is variable, from lighter to darker, and this variation is not related to the geographical distribution. However, the antennal pubescent pattern is very constant, as well as the light elytral pubescent band along the suture, facilitating the identification of the species. Therefore, we synonymize B. (B.) petilus with B. (B.) pulvereus . This species belongs to the group with the lower eye lobes distinctly longer than the genae.

Currently, this species is known from Costa Rica, Panama, French Guiana, Brazil (Amazonas, Pará, Rondônia) (which included the geographical distribution of B. (B.) petilus ) ( Bezark 2022b; Monné 2022; Tavakilian & Chevillotte 2021).
