Romeria texana (Price1937) Artinskian, Early Permian, ~280 mya, ~25 mm skull length, was derived from a sister to Thuringothyris and phylogenetically preceded Reiszorhinus. Another specimen of Romeria, R. primus, is not congeneric according to the results of the present study.
Distinct from Thuringothyris, the skull of Romeria texana had a narrower snout in dorsal view with nares that opened laterally. The rostral profile also narrowed and descended further. Two maxillary teeth were larger than the others.
