The species is named in honour of Dr Charles Griswold (Californian Academy of Sciences, San Francisco), who collected numerous Tidarren specimens included in this study.
Diagnosis
Tidarren griswoldi has a pointed, triangular, anteriorly directed epigynal protuberance ( Figures 200–203 View Figures 200–203 ). Copulatory ducts are fused at entrance and short. Male unknown.
Measurements (mm)
[♀, n 54, minimum–maximum (mean).] Total length 2.11–2.35 (2.20), carapace length 0.82–0.88 (0.85), width 0.70–0.74 (0.72), length femur I 1.31–1.44 (1.37), tibia I 0.78– 0.86 (0.81). Abdomen 1.56–2.15 (1.84) high, 1.25–1.56 (1.36) long, and 1.13–1.49 (1.30) wide. Ventral side (distance petiolus to spinnerets) 0.94–1.21 (1.02) long. Clypeus 0.18– 0.20 (0.19) high. Chelicerae 0.27–0.35 (0.32) long. Sternum 0.51–0.55 (0.52) long and 0.47 wide. Labium 0.10 long and 0.19 wide. Gnathocoxae 0.28 long and 0.13 wide (mean). Leg formula 1423, see Table XVI.
Somatic features, colouration
Sternum without posterior small tubercle. Abdomen higher than long, ending in tubercle ( Figure 175 View Figures 172–180 ). Carapace uniformly dark brown. Chelicerae, gnathocoxae, and labium light brown or brown. Sternum dark, with light yellow central area surrounded by several light yellow spots. Pedipalps and legs light yellow with large dark annulations and patches. Abdomen brown to dark brown, dorsal and aboral white line pattern as in T. afrum . Sides with a few white guanin patches. Epigastric region dark, book lung covers light yellow. Venter dark with two small white spots near spinnerets. Spinnerets brown.
Epigynum, vulva ( Figures 200–203 View Figures 200–203 )
Epigynal protuberance distinctly protruding ( Figures 175 View Figures 172–180 , 200 View Figures 200–203 ), ca 0.13–0.14 mm long, directed anteriorly; its shape triangular and pointed, in lateral view tip slightly bent ( Figure 200 View Figures 200–203 ). In aboral view protuberance clearly delimited from surrounding integument ( Figure 202 View Figures 200–203 ). Copulatory ducts fused at entrance ( Figure 201 View Figures 200–203 ), short, only 0.07 mm long. Copulatory orifices at anterior border of epigynal protuberance, in ventral and dorsal view close to posterior end of receptacula. Copulatory ducts run anteriorly for a short distance and abruptly diverge laterally. They enter receptacula posteriorly, at inner side. Receptacula seminis 0.15 mm long and 0.10 mm wide. Epigynal protuberance almost as long as receptacula ( Figure 201 View Figures 200–203 ).
