Luis de Armas recently published an article where he revalidated three recently synonymized Cuban species of Heteroctenus Pocock, 1893 (Buthidae) (the three species previously belonged to Rhopalurus Thorell, 1876). This means that the following species are considered valid:
Heteroctenus aridicola (Teruel et Armas, 2012)
Heteroctenus melloleitaoi (Teruel et Armas, 2006)
Heteroctenus granulimanus (Teruel, 2006)
In addition, the buthid subfamily Rhopalurusinae Bücherl, 1971 is regarded as a junior synonym of Centruroidinae Kraus, 1955.
For more information about the synonymization of the three species, see my blog post from yesterday.
The scorpion genus Heteroctenus Pocock, 1893 was restored from synonymy with Rhopalurus in a recent revision by Esposito et al. (2017). Here, we restore two eastern Cuban species Heteroctenus melloleitaoi (Teruel et Armas, 2006) and H. aridicola (Teruel et Armas, 2012) as valid species. They were synonymized by Esposito et al. (2017) under Heteroctenus junceus (Herbst, 1800), without examination of corresponding specimens and with erroneous interpretations of some aspects of the original descriptions. Heteroctenus granulimanus (Teruel, 2006) is also restored as a valid species. The subfamily Rhopalurusinae Bücherl, 1971 is regarded as a junior synonym of Centruroidinae Kraus, 1955.
