Stygophrynus Kraepelin, 1895

Stygophrynus Kraepelin, 1895: 44 ; Kraepelin, 1899: 248; Pocock, 1900: 129; Gravely, 1915: 443; Mello-Leitão, 1931: 53; Werner, 1935: 471; Weygoldt, 2000: 25.

Type species. – Charon cavernicola Thorell, 1889 , by original designation.

Diagnosis. – Principally having three or two major spines on the dorsal surface of the pedipalpal patella, a divided pedipalpal tarsus and at least three spinelets on the pedipalpal tibia both dorsally and ventrally ( Kraepelin, 1895; Gravely, 1915; Dunn, 1949; Weygoldt, 2000).

Remarks. – Stygophrynus is a member of Charontidae which is characterized by the presence of a row of setae on the proximal edge of the cleaning organ on the pedipalpal tibia ( Quintero, 1986; Harvey & West, 1998; Weygoldt, 1996, 2002). The only other genus of the family, Charon Karsch, 1879 , is distinguished from Stygophrynus by the presence of only two major spines on the pedipalpal patella and an undivided pedipalpal tarsus (Harvey & West, 1998; Weygoldt, 2000). Dunn (1949) proposed the subgenus Stygophrynus (Neocharon) to accommodate S. moultoni from Kalimantan and S. forsteri from the Solomon Islands.
