From editor or global species database
Taxonomic remark Graff (1882) tranfers the species to Pseudorhynchus but with hesitation, as Uljanin (1870) does not mention a scelortised copulatory organ. He repeats that opinion in 1905, and there considers the species incertae sedis, keeping it in Vera. In his work of 1913, he mentions it as a species dubia (p.354–355). The name of genus and species are not mentioned by any author after 1913. [details]
