Within the subgenus Unionicola, V 2 gland larger than dorsal glandularia is rare according to the available literature. Generally, gland of V 2 is as large as those of A 1, D 1, L 4, etc. in the known species, like U. crassipes, of the subgenus; II-L-6 dorsally with one long awl-shaped seta, which again is an unusual character differing from other members of the subgenus Unionicola; the three thick inner setae on acetabular plates are very short and do not reach to acetabula in female in the new species, while they are long and at least overring the margin of adjacent acetabulum in all known members of the subgenus. Although U. (U.) suiyangensis sp. nov. is similar to U. (U.) xishuiensis sp. nov. in the shape of palp, coxae and genital field, they can be distinguished by: (1) Chelicera with one proximal sickle-shaped projection in U. xishuiensis, but normal in U. suiyangensis; (2) Ventral apodeme of infracapitulum bent as a hook in U. xishuiensis, while it almost straight in U. suiyangensis; (3) II-L-6 dorsally with one long awl-shaped seta in U. xishuiensis; but smooth and normal in U. suiyangensis.</p> <p>Etymology. The species is named after the county (Suiyang) from where it was collected.</p> <p>Habitat. Pond, with submerged plants, Hydrilla verticillata, Potamogeton crispus etc..</p> <p>Distribution. China (Guizhou province).</p></div> 	http://treatment.plazi.org/id/DA198791FFF2FF8312FEE41B5793734B	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.
