Ricinoides Ewing, 1929  

Cryptostemma Guérin-Méneville, 1838: 11   [junior homonym of Cryptostemma Herrich-Schäffer, 1835   ( Insecta  : Hemiptera   )], type species by monotypy: Cryptostemma westermannii Guérin-Méneville, 1838   ; Gervais, 1844: 130, 131; Karsch, 1892: 30–32; Hansen and SØrensen, 1904: 146.

Ricinoides Ewing, 1929: 586   [replacement name for Cryptostemma Guérin-Méneville, 1838   ]; Petrunkevitch, 1955: 160; Harvey, 2003: 182.

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.
