DIAGNOSIS: Paracharon shares the following characters with Jorottui , gen. nov.: 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); and cushionlike female gonopods (fig. 20B; Weygoldt, 1999: 106, fig. 1).

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

DISTRIBUTION: Paracharon is endemic to the West African country of Guinea Bissau, where it has been recorded at two localities, Bolama and Rio Cassine (fig. 2) .
