Cenobiopelma mimetica Mello-Leitão & Arlé; nomen nudum.

Mello– Leitão & Arlé (1934) presented a summarized description of a moult. They mentioned that a detailed description of a type specimen of their new species would be published, but it never was. Therefore, no typematerial was designated. In the case of genus-group names published after 1930 the description must be accompanied by the fixation of a type. Otherwise, the name is not valid, and since the type species lacked a type specimen, both are here considered nomina nuda.
