“Female (allotype): Total length 19.0, chelicera length 6.2, chelicera width 2.8, propeltidium length 2.0, propeltidium width 3.6, palpus length 12.0, first leg length 9.0, fourth leg length 17.5. Ratios: A/CP 4.70, CL/CW 2.20, PL/PW 0.55, GOL/GOW 0.82. Female paratypes (5): Total length 17.0–26.0, chelicera length 4.8–7.6, chelicera width 1.8–3.4, propeltidium length 2.0–3.0, propeltidium width 3.5–5.0, palpus length 12.0–16.0, first leg length 9.0–13.0, fourth leg length 16.0–22.0. Ratios: A/CP 4.70–5.66. CL/CW 2.20–2.67, PL/PW 0.48–0.63, GOL/GOW 0.74–0.82” (Brookhart & Cushing, 2004, p. 300). 

 

            Ctenidia Description: Male ctenidia: “Four stiletto shaped ctenidia on first post-spiracular sternite extending approximately half the length of the sternite (Fig. 7)” (Brookhart & Cushing, 2004, p. 300). 

Female ctenidia: “2–3 tiny hairlike ctenidia were present on two specimens, the rest had none” (Brookhart & Cushing, 2004, p. 300). 

            

            Operculum Description: “Genital operculum with longer, broad arms, a long, slightly recurved medial surface ending in a point, wing short to absent, and posterior edge truncated (Fig. 9)” (Brookhart & Cushing, 2004, p. 300). 

            

            Chelicerae Description: Male chelicerae: “Fixed finger of chelicera with little or no crimping, fondal notch longer than wide; width of FF 80% the width of FN; MF with large primary tooth, and a ridge that is slightly elevated anteriorly instead of intermediate and anterior teeth, MST intermediate in size (Fig. 5–6)” (Brookhart & Cushing, 2004, p. 300).

Female chelicerae: “Chelicera typical of species; MF with posterior IT separate from PT, MST indistinct to absent (Fig. 8)” (Brookhart & Cushing, 2004, p. 300). 

 

Diagnosis: “Eremobates icenoglei new species appears most closely related to E. zinni but is separated from it and others of the scaber group by absence of AT on male MF, a fond that is noticeably longer than wide, and a thickened FF. The female genital operculum is distinctive (Fig. 9)” (Brookhart & Cushing, 2004, p. 300).

 

Other Information: “Eremobates icenoglei appears to be restricted to the Coastal Chaparral habitat. It was found by Wendell Icenogle in buildings and in pitfall traps” (Brookhart & Cushing, 2004, p. 300).
