Roberts , E. Marais ), deposited in NMNW (ex 41492, PBI _OON 33774) . ETYMOLOGY: The specific name is a noun in apposition taken from the type locality. DIAGNOSIS: Males differ from those of D. parvimana in having a longer embolus (figs. 185, 186), from those of D. tsumkwe in lacking cheliceral apophyses and having an unsclerotized palpal conductor (figs. 209, 210), and from those of D. griswoldi in having a narrow embolus (figs. 185, 186); females have much larger ridges at the anterior end of the genital area (fig. 215) than do those of the other known females. MALE (PBI_OON 33774, figs. 173–210): Total length 2.13. Posterior eye row straight from front. Chelicerae anterior face unmodified. Epigastric furrow unmodified. Leg spination: tibiae: I d0-1-1, p1-0-1, v0-0-2, r1-0-1; II d0-0-1, p1-0-1, v0-0-2, r1-0-0; III d0-0-1, p0-0-1, v1p-1p-2, r0-0-1; IV d0-0-1, p0-0-1; metatarsi: I p1-0-0, v0-0-1p, r1-0-0; II p0-0-1, v0-0-1p; III v0-1p-1p; IV p0-1-0, v0-1p-1p, r0-1-0. Palp with embolus long, thin, basally sinuous, accompanied by long, thin, parallel, translucent conductor. FEMALE (PBI_OON 33774, figs. 211–241): Total length 2.24. Palpal spines absent. Leg spination: tibiae: I p1-0-1, v0-0-1r, r1-0-1; II p1-0-1, v0-1p-1r, r1-0-1; III, IV d0-0-1, p1-0-1, v0-1p-1p, r1-0-1; metatarsi: I, II d1-0-0, p1-0-0, r1-0-0; III d1-0-0, v2-0-1p, r1-1-0; IV d1-1-0, p1-1-0, v1p-0-1p, r1-1-0. Epigastric area with pair of elevated, anteriorly and medially sclerotized paramedian ridges, anterior genitalic projection with narrow anterior extension.
