DIAGNOSIS: Jorottui , gen. nov., shares the following characters with Paracharon : the complete absence of ocelli (fig. 5); pedipalp femur with four primary ventral spines (fig. 14A, C, E); pedipalp patella with three primary dorsal spines and four primary ventral spines (fig. 15); pedipalp tarsus with three dorsal spines (fig. 17B, D, F) and one ventral spine (fig. 17A, C, E); cushionlike female gonopods (fig. 20B; Weygoldt, 1999: 106, fig. 1).

Jorottui may be readily distinguished from Paracharon as follows: carapace anterior projection with lateral margins linear in Jorottui (fig. 5A, B) but curved in Paracharon (fig. 5C); prolateral margin of cheliceral basal segment with four teeth (distal tooth bicuspid) in Jorottui (fig. 8A, C) but three teeth (distal tooth bicuspid) in Paracharon (fig. 8E); ventral apophysis of pedipalp trochanter at least 2× length of trochanter and adorned with large setiferous tubercles in Jorottui (fig. 13C, E) but similar in length to trochanter and adorned with small setiferous tubercles in Paracharon (fig. 13A); two dorsal spines of pedipalp trochanter long in Jorottui (fig. 13D, F) but short in Paracharon (fig. 13B); pedipalp femur with one large dorsal spine situated near distal margin in Jorottui (fig. 14D, F) but two small dorsal spines situated near distal margin in Paracharon (fig. 14B); pedipalp tibia with four or five primary dorsal spines and four to six primary ventral spines (fig. 16C–F) in Jorottui but three primary dorsal spines (fig. 16B) and two or three primary ventral spines (fig. 16A) in Paracharon .

ETYMOLOGY: The new genus is named after the Wayuu word “ Joróttui ” which means “place where perennial clarity reigns.” The Wayuu people, original inhabitants of the area in which the new taxon occurs, believe Joróttui is a large cave inside the earth that represents the luminous dome of the sky. The name is a noun in apposition and is masculine in gender.
