            Holotype: Male holotype, female allotype; California, San Diego County, Mt. Palomar St. Park (338209N, 1168549W), 13 July 1953, W.J. & J.W. Gertsch (AMNH)” (Brookhart & Cushing, 2004, p. 304).

            

Measurements: Male holotype: Total length 19.0, chelicera length 5.63, chelicera width 2.58, propeltidium length 2.50, propeltidium width 4.36, palpus length 18.0, first leg length 13.0, fourth leg length 21.5. Ratios: A/CP 6.46, CL/CW 2.18, PL/PW 0.57, FL/FW 1.00, FW/FFW 1.45, CW/FFW 5.64. Male paratypes (4): Total length 19.0–20.0, chelicera length 5.00– 5.63, chelicera width 2.42–2.58, propeltidium length 2.50–2.92, propeltidium width 4.17–4.38, palpus length 16.0–18.0, first leg length 12.0–14.0, fourth leg length 20.0–21.5. Ratios: A /CP 6.06–6.46, CL/CW 2–2.18, PL/PW 0.62–0.7. FL/FW 0.71–1.00, FW/FFW 1.17–1.70, CW/FFW 5.00–6.00” (Brookhart & Cushing, 2004, p. 304-305).

“Female allotype: Total length 19.0, chelicera length 5.29, chelicera width 2.08, propeltidium length 2.29, propeltidium width 3.83, palpus length 12.0, first leg 12.0, fourth leg length 19.0. Ratios: A/CP 5.27, PL/PW 0.60, CL/CW 2.54, GOL/GOW 0.72. Female paratypes (2): Total length 20.0–20.5, chelicera length 6.25–6.50, chelicera width 2.5, propeltidium length 2.5—2.6, propeltidium width 4.50–4.58, palpus length 14.5–15.0, first leg length 12.0, fourth leg length 18.0–19.0. Ratios: A/CP 5.97–6.00, CL/CW 2.5, PL/PW 0.57, GOL/GOW 0.5–0.6” (Brookhart & Cushing, 2004, p. 305).

 

            Palpal Description: 47–60 palpal papillae, a few on tarsus (Fig. 13)” (Brookhart & Cushing, 2004, p. 304).

 

            Ctenidia Description: 4 short needle like ctenidia extending less than half the succeeding segment (Fig. 14)” (Brookhart & Cushing, 2004, p. 304).

            

            Operculum Description: Genital operculum with long, broad arms, long curved medial edge ending in a point, short, offset wings, curved posterior margin (Fig. 16)” (Brookhart & Cushing, 2004, p. 305).

            

            Chelicerae Description: Male cheliceral FF regularly curved, MF with large PT, small triangulate AT with a cleft, small IT, posterior IT separate from PT (Figs. 11–12)” (Brookhart & Cushing, 2004, p. 304).

Female: “Chelicerae typical with posterior IT of MF in the notch, no cleft under AT (Fig. 15)” (Brookhart & Cushing, 2004, p. 305).

 

Diagnosis: Eremobates socal can be separated from E. zinni and E. mormonus by size and shape of ctenidia, color variation and female genital operculum” (Brookhart & Cushing, 2004, p. 304).

 

Other Information: Eremobates socal is similar to E. zinni and E. mormonus but can be separated by the shape and size of the ctenidia, coloration, and shape of female genital opercula. It was found in the coastal shrub area on Mt. Palomar in San Diego County, California” (Brookhart & Cushing, p. 305).
