Venter. Venter covered with striae. Humeral and coxisternal shields absent. Ventral podosoma with three pairs of setae (1a, 3a, 4a). Aggenital area with three pairs of aggenital setae (ag 1–3). Anogenital shields with one pair of genital setae (g 1) and three pairs of pseudanal setae (ps 1–3).

Legs. Leg I 235; leg II 205; leg III 213; leg IV 220. Counts of setae on leg segments as follows (solenidia in parenthesis): coxae 2–1–2–2, trochanters 1–1–1–0, femora 4–4– 3–2, genua 4(Κ)–3–1–1, tibiae 6(ϕρ)–6(ϕρ)–6(ϕρ)–6(ϕρ), tarsi 12(ω)–10(ω)–8(ω)–8(ω).

Gnathosoma . With two pairs of adoral setae (ro 1,2) distally, one pair of subcapitular setae (m) proximally. Length of subcapitular setae: m 33; distance between the setae: m–m 38. Chelicera 88. Palp 125. Palp setal formula (from trochanters to tarsi) 0–3– 1–3+1 claw–7 (including solenidion and eupathidium), eupathidium trifid distally.

Male and other immature stages

Unknown.

Etymology

This species is named after the country in which it was found.

Remarks

The new species differs from all others except for Mediolata californica Gonzalez- Rodriguez, 1965 by having three setae on palp femur and the details of leg chaetotaxy. It can be distinguished from M. californica by suranal shield being clearly separated from opisthosomal shield, tucked under body.
