Diagnosis
Tayshaneta sprousei may be separated from all Tayshaneta species by having the following combination of characters: male palpal tarsus undivided, tapering apically (Fig. 48C); retrolateral tibial spine elongate, 0.5× length of palpal tarsus; embolus oval, smooth along margins (E, Fig. 48D); ventral sclerite short, less than the width of the embolus (Fig. 48B, D–F).

Male (holotype). Body length 1.1, carapace 0.47 long, 0.40 wide, length 1.18× width. Carapace pale yellow, sparsely setose; eyes surrounded by faint dark markings (Figs 27A–C). Legs elongate and thin, femur I 1.19× carapace length, covered in fine setae and with few scattered spines. Palpal tarsus entire, tapering apically (TS, Fig. 48C); retrolateral tibial spine straight, sculptured throughout, length 0.49× tarsus length. Bulb suboval, length 1.52× width; embolus oval, smooth along margins (E, Fig. 48D), length 2.0× width; ventral sclerite short, less than embolus width (VS, Figs 48B, D–F). Abdomen pale yellow, without pattern, 0.63 long, 0.50 wide, covered in fine setae.
