According to Bezark et al. (2018): “1. We did not examine any specimens of Dorcasta from Hispaniola. Therefore, it is not possible to know if there are differences between D. dasycera and D. gracilis based solely on the original descriptions and photographs of the holotypes; 2. According to Martins & Galileo (2001), when comparing D. singularis with D. gracilis , the outer elytral spines in D. gracilis are convergent. Although they appear that way in the holotype of D. gracilis , the feature is variable in D. dasycera , and the spines can be distinctly convergent as well, independent of the locality.” Now, we examined specimens from the Dominican Republic, and can confirm that D. gracilis is a junior synonym of D. dasycera , because there no differences between these specimens from the Dominican Republic and specimens from Venezuela. For complete references on the three synonyms see Monné (2020b) and Tavakilian and Chevillotte (2019).
