Diagnosis.

Males of S. navicularis can be distinguished from all other congeners by the navicular median apophysis (Fig. 9A ). The female of S. navicularis is distinguished from other congeners except S. chengguanensis and S. shenhei sp. nov. by the scape with a moderate size, utterly exposed, like a shield attached to the abdomen (Figs 6D , 10E , 13D ) (scape not as above, either distintly long and narrow, such as S. bicornis , S. cavernicola , S. chi sp. nov. and S. xiaotu sp. nov. as in Figs 2E-G , 4E-G , 8E-G , 16E-G , or distintly short and wide, such as S. nitida and S. shuidi sp. nov. as in Figs 11C-E , 14C-E ), but differ from the latter two by the scape almost completely membranous, rugose (more sclerotized, not rugose in S. chengguanensis and S. shenhei sp. nov.) (cf. Fig. 10E-G and Figs 6D-F , 13D-F ).
