N2 - The modestly diverse order Amblypygi Thorell, 1883 includes five families, of which Charinidae Quintero, 1986 is the most diverse and with the widest geographical distribution. The family currently comprises three genera, Catageus Thorell, 1889, Charinus Simon, 1892 and Sarax Simon, 1892, the first known by one species from a single locality in Myanmar, the second with currently 74 species globally distributed, and the last with 17 species present in Southeast Asia and India. In this paper we describe and illustrate a new genus to accommodate the species Sarax davidovi Fage, 1946 based on unique characters. Weygoldtia gen. nov. (Laos, Vietnam and Cambodia) is supported by two synapomorphies: the presence of a straight crest anterior to the lateral eyes and the longitudinal orientation of the rod sensilla on tarsus of leg I. The new genus can be distinguished from Charinus and Sarax by the number of trichobothria on distitibia IV and the presence of one or two setae on the base of the cleaning organ on pedipalp tarsus. The enigmatic species Catageus pusillus Thorell, 1889 (the single species in the genus) is here synonymized with Stygophrynus cavernicola (Thorell, 1889) (family Charontidae Simon, 1892) and a neotype is designated. As Stygophrynus cavernicola is the type species of the genus, the synonymization of the two species results in the synonymy of the genera. Following the principle of priority, Catageus is maintained and all nine species of Stygophrynus Kraepelin, 1895 now have the following new combination: Catageus berkeleyi (Gravely, 1915), comb. nov., C. brevispina (Weygoldt, 2002), comb. nov., C. cavernicola, comb.nov., C. cerberus (Simon, 1901), comb. nov., C. dammermani (Roewer, 1928), comb. nov., C. longispina (Gravely, 1915), comb. nov., C. moultoni (Gravely, 1915), comb. nov., C. orientalis (Seiter and Wolf, 2017), comb. nov. and C. sunda (Rahmadi and Harvey, 2008), comb. nov.
