The described specimen is very similar to Gephyrotes sp. as described by Moissette (1988) in having a pair of avicularia associated with the aperture, and 5-6 pairs of fused costulae on its frontal wall. Specimens described by Berning (2006) are also very similar to the studied specimen, but the preservation of our specimen does not permit a precise determination.
