Dioryx ruyangensis Hu, Yin, & Chen, 2004: 704-705.

Dioryx ruyangensis - Páll-Gergely et al. 2017: 10.

Type locality.

"Ruyang Town, Ruyuan County (24°7'N, 113°2"E), Guangdong Province, China".

Remarks.

The holotype (IZCAS TM 132794) and a paratype (IZCAS TM 132795-132805) were photographed by one of us (Meng Kaibaryer). The shell height was 4.7 and 4.6 mm respectively, whereas it is given as 7.1 mm in the original description. Moreover, the examined specimens were much more corpulent than the one imaged in Hu et al. (2004), indicating that they belong to another species. Consequently, the types of this species are considered lost.
