From editor or global species database
New combination Ma (1988) synonymized the genera Pseudocardinia, Jiangxiella and Hamiconcha with Acyrena and established several new combinations. Even though these combinations may be the last published ones for some of the species, all the abovementioned genera were treated as valid in the catalogues by Fang et al. (2009) and Nevesskaja et al. (2013). Revision required! [details]
