kuatunensis sp. nov. (China: Fujian), and G. (B.) longshengensis sp. nov.
(China: Guangxi). They are characterized by the presence of setae on the

photographs, illustrations of diagnostic characters and a distribution map are
provided. Ovoviviparity is newly recorded in G. (B.) longshengensis sp. nov.
