Remarks. Despite its abundance in our samples, this species is not commonly cited in the literature. Following Petrushevskaya (1971), we consider this species to have an elongated spiny cephalis with indistinct neck area, and a broad thorax (~2x the cephalis width) with numerous ribs and extended spines. Illustrations published under the names Lithomelissa cf. galeata Ehrenberg (Benson, 1966), Lophophaena variabilis Popofsky (Van de Paverd, 1995), and Lophophaena buetschlii Haeckel (Van de Paverd, 1995) best fit the description of Lophophaena nadezdae in our opinion, so these specimens are included in our synonymy.
Range. Late Miocene—Recent, EEP (Table 1).
