Type species

Weygoldtia davidovi ( Fage, 1946) , by original designation.

Diagnosis

Weygoldtia may be distinguished from the other two genera of Charinidae by the presence of a straight carina anterior to the lateral eyes ( Fig. 151A ), as well as the following combination of characters: tritosternum projected anteriorly with pair of prominent setae near anterior pair of setae; pedipalp tarsus with one or two setae at base of ventral row of cleaning organ; leg IV distitibia with seven to nine trichobothria in sc and sf series.

Etymology

Patronym honoring Dr Peter Weygoldt for his contributions to arachnology in general and Amblypygi in particular.

Remarks

The number of articles on the tibia and tarsus of leg I in Weygoldtia is similar to that in species of Catageus , but the two genera may be distinguished by the dorsal spines on the pedipalp trochanter of Catageus , which are absent in Weygoldtia ; the different numbers of trichobothria in the frontal and caudal rows of the distitibia in Catageus , which are equal in Weygoldtia ; the absence of a straight carina anterior to the lateral eyes, a synapomorphy of Weygoldtia ; and spines between dorsal spine 1 and the proximal margin of the pedipalp femur.

Weygoldtia belongs to the family Charinidae ( Miranda et al. 2021), not Charontidae , due to the following characters: spines absent on pedipalp trochanter; small dorsal spines and ventral spines absent from pedipalp tibia; pedipalp tibia with two dorsal spines, distal spine longer than proximal, instead of one long spine proximally, with small spine close to its base, followed by smaller spines; pedipalp tibia ventral spine situated distally, near distal margin of tibia, instead of proximally; only one seta, instead of several, at base of cleaning organ on pedipalp tarsus; equal number of trichobothria in sc and sf series of leg IV distitibia.

Key to the identification of the species of Weygoldtia ( Fig. 150 )
