Diagnosis.
Tayshaneta whitei may be separated from all Tayshaneta species, except Tayshaneta bullis and Tayshaneta microps , by having a combination of males with an elongate retrolateral tibial spine, more than 0.5 × length of the palpal tarsus and lacking a ventral sclerite (Figs 51B, E). Separated from Tayshaneta bullis and Tayshaneta microps by the unique shape of the embolus (E, Fig. 51D) and the distinctive retrlolateral sclerite (RS, Figs 51 D–E).
Description.
Male (holotype). Body length 1.52, carapace 0.61 long, 0.50 wide, length 1.21 × width. Carapace brown, sparsely setose; eyes surrounded by dark markings (Figs 30 A–C). Legs elongate and thin, femur I 1.61 × carapace length, covered in fine setae and with few scattered spines. Palpal tarsus undivided, tapering apically; retrolateral tibial spine straight, sculptured throughout, length 0.51 × tarsus length. Bulb suboval, length 1.71 × width; embolus subquadrate, with small basal tooth (E, Fig. 51 D–F), length 1.6 × width. Abdomen white, without pattern, 0.90 long, 0.67 wide, covered in fine setae.
Variation(n = 4). Total length 1.52-1.70; carapace length 1.16-1.21 × carapace width; length femur I 1.45-1.92 × carapace width.
Female (Lithic Ridge Cave).Body length 1.49, carapace 0.61 long, 0.49 wide, length 1.25 × width. Carapace light brown, sparsely setose; eyes surrounded by dark markings (Figs 30 D–F). Legs elongate and thin, femur I 1.58 × carapace length, covered in fine setae and with few scattered spines.Atrium oval, length 0.5 × width, spermathecae with twisted stalks and large, circular heads (Fig. 54E).Abdomen light brown, 0.90 long, 0.60 wide, covered in fine setae.
Variation(n = 3). Total length 1.41-1.80; carapace length 1.18-1.28 × carapace width; length femur I 1.33-1.58 × carapace width.
