Thalassiphora elongata Vasilyeva in Vasilyeva et al., 2001, p.67–68, pl.1, figs.1–2,6 ex Vasilyeva in Andreeva-Grigorovich et al., 2011, p.31–32, pl.4, figs.1–8.

This species was not validly published in Vasilyeva et al. (2001), since no English or Latin diagnosis was provided. We provisionally interpret the five images listed as the holotype to represent a single specimen that has been manipulated; if it is found that they represent more than one specimen, the name Thalassiphora elongata would remain to be validated.

Holotype: Andreeva-Grigorovich et al., 2011, pl.4, figs.1–5.
Age: late Eocene–early Oligocene.
