Abstract
Electrolana madelinae Schädel, Hyžny & Haug, 2021 was described from two excellently preserved isopod specimens from ca. 40-million-year-old amber from Myanmar. Appraisal of the two specimens and their comparison to extant genera and species of Cirolanidae show that the genus Electrolana Schädel, Hyžny & Haug, 2021 is a junior synonym of Cirolana Leach, 1818, and that the holotype and paratype represent two distinct species. The holotype is placed in the combination Cirolana madelinae (Schädel, Hyžny & Haug, 2021) comb. nov., and the paratype, a species of Metacirolana Kussakin, 1979, is here diagnosed and named Metacirolana jimlowryi sp. nov. Brunnaega roeperi Polz, 2005 is transferred to Cirolana roeperi (Polz, 2005) comb. nov.
