TYPE: Female holotype from Berlese sample of forest litter taken at an elevation of 300 m at a site 73 km NE of Chone and 85 km W of Santo Domingo, Manabı´, Ecuador (June 12, 1976; S., J. Peck), deposited in FMNH (PBI_OON 37831) .

ETYMOLOGY: The specific name is a patronym in honor of Cristina Rheims of the Instituto Butantan, in recognition of her many contributions to the success of the Niarchos Expedition.

DIAGNOSIS: Males are unknown; the single known female has enigmatic genitalia, possibly including a membranous anterior receptaculum that was lost in preparation, but easily distinguishable from all the other known females by the shape of the posterior apodemes, which are almost as long as the entire epigastric scutum (figs. 707, 708).

MALE: Unknown.

FEMALE (PBI_OON 37831, figs. 699– 708): Total length 1.82. Posterior eye row procurved from above; PME separated by their radius to diameter, PLE-PME separated by PME radius to PME diameter. Sternum surface smooth. Leg spination: tibiae IV v0- 0-2. Postepigastric scutum with long apodemes bearing sinuous anterior margins; details of anterior receptaculum unknown (figs. 707, 708).
