Diagnosis.The shape of the male chelicera with its slightly rounded fondal notch, a tiny MM, and a flattened ridge-like MD distinguishes this species from all other Eremocosta.Only E. gigasellahas a ridge-like structure positionally homologous to the sharper distal ridge that might be a modified MD (see Figs. 2S & O, arrows). Eremocosta gigashas a distinctive MD tooth at that same position on the movable finger ( Fig. 2K, arrow). The genital operculum of E. striatais most similar to that of E. calexicensis; however, the curved distal portions of the genital wings are more rounded than those of E. calexicensis(compare Figs. 4E & B).
Measurements. Males (n = 8).TL 31.0–50.0; CL 9.0–16.0; CH3.4–5.6; FNL 0.3–2.0; FNH 0.4–0.9; FFH 1.0–1.6; PL 25.0–40.5; PT 7.0–8.0; PMT 1.7–3.0; LI 20.5–31.0; LIV 27.0–43.0; PPL 5.0–7.9; A/CP 4.3–5.6; FNL/ FNH 0.5–2.5; FFH/FNH 1.3–2.3; FFH/ CH0.2–0.5. Measurements. Females (n = 2).TL 34.5, 50.0; CL 9.0, 17.5; CH4.0, 5.5; PL 22.0, 35.0; PT 7.5, 7.7; PMT 2.0, 2.9; LI 19.5, 26.0; LIV 34.5, 35.0; PPL 3.9, 4.0; A/CP 3.9, 4.0. Description. Coloration. Male.Overall dusky yellow body and appendages; legs dusky violet-brown at tibiafemur joint. Propeltidium reticulate violet-brown with a longitudinal lighter stripe the width of the eye tubercle ( Fig. 5G). Abdomen dark dorsally and lighter ventrally. Chelicera. Male.VDC apical, oriented prolaterally, narrow, with thin carina ( Fig. 1F, arrow). Fixed finger broad at the base narrowing at the apical third of the length in retrolateral view with no median dentition. Movable finger: prominent MP-two tiny MSM (some specimens with just one)-either a very small, but distinct, MM or just a slight ridge at that location (difficult to see in Fig. 2S)-a long ridge-like MD; distinct MPL ( Figs. 2S & T). Fondal notch seemingly curved and distinct ( Figs. 2S & T). Two tiny RFA; fondal teeth graded I, III, II, IV retrolaterally and I, II, III, IV prolaterally ( Fig. 3F). Setation. Male.Typical. Coloration. Female.Coloration as in the males but sometimes markings are less distinct. Chelicera. Female.Fixed finger: large FP-2 small FSM-FM-2 small FSD-smaller FD. Movable finger: large MP-two small MSM-medium MM; smaller but distinct MPL ( Figs. 2U & V). Two RFA, proximal tiny; fondal teeth graded as in the male. Setation. Female.Typical. Genital operculum. Muma’s illustration is accurate (1951, fig. 31, p. 46). Thin anterior arms; relatively large posterior wings ( Fig. 4E).
Distribution. USA Arizona. MÉXICO: Sonora. Biome: Sonoran Desert.
Discussion. Eremocosta striatais a large species that can be seen by vehicle headlights scurrying across a road (pers. obs, JB). It seems to occupy the Sonoran region east of the ColoradoRiver in Arizonaand the state of Sonora, México.
