Protagonista lugubris, a cockroach species new to China and its contribution to the revision of genus Protagonista, with notes on the taxonomy of Archiblattinae (Blattodea, Blattidae).
The blattid genus Protagonista Shelford, 1908, which is tentatively assigned to the subfamily Archiblattinae (= Planeticinae), is reported from China for the first time with illustrations and description of Protagonista lugubris Shelford, 1908. It is a wood-dwelling and potentially a wood-feeding species. The male and female genitalia of Protagonista are described and illustrated for the first time. The species Protagonista pertristis Hanitsch, 1923 is revived from the synonymy of Protagonista lugubris, and the remaining three nominal species that were also considered as synonyms of Protagonista lugubris are now recognized as synonyms of Protagonista pertristis. In agreement with Princis (1965), we propose that Eroblatta Shelford, 1910, a genus closely related to Protagonista, should be placed in the subfamily Archiblattinae rather than Blattinae. However, the taxonomy of Archiblattinae is problematic and awaits revision. Photos and a key to species of Protagonista and Eroblatta are provided, including photos of the holotypes of the synonymized nominal species. In addition, although Planeticinae is the senior synonym of Archiblattinae, the priority of the latter should be maintained since it is in prevailing usage based on the Article 40.2 in ICZN 4(th) edition.
