REMARKS. Copious specimens of Omalus stella were collected by M.V. Mokrousov in Astrakhan Prov. and by V.L. Kazenas in Kazakhstan. All these specimens are brilliant red compared with specimens from Tajikistan, which are green with golden reflections (Rosa et al., 2015a). The Russian and Kazakh specimens could be a color variation of the western population, or a separate species, even if we could not find major morphological characters to identify them.
