DIAGNOSIS: Ricinoides has traditionally been separated from the New World genera, Cryptocellus and Pseudocellus , by the presence of three characters: a pronounced toothlike process, the so-called Ricinoides tooth, on the dorsal surface of the cheliceral manus (fig. 3A); the tarsus of leg I and terminal tarsomere of leg II and, especially, III and IV, sublinear dorsally, covering the ungues; a large lateral lobe, referred to herein as the prolateral laminar (PL) lobe, on the male copulatory apparatus ( Tuxen, 1974; Platnick, 1980). Two other, putative synapomorphies of Ricinoides , both on the cheliceral movable finger, were identified in the present investigation: a sharp, prodorsal longitudinal carina aligned with the teeth (fig. 3A); and a shallow, prolateral excavation, delimited by two parallel carinae, on the mucron (fig. 3B). These new characters, observed in all known species of Ricinoides , were confirmed absent in the type species of Cryptocellus and Pseudocellus based on examination of the type specimens.
