01. Considerable variability has been reported in the literature for the number of teeth on the fixed digit of the chelicera, ranging from one tooth (
Chant and Yoshida-Shaul 1987
;
Denmark
1992
) to four teeth (
Ragusa and Swirski 1978
;
Chant and Yoshida-Shaul 1987
). Specimens collected in
Spain
have two teeth in addition to the
pilus dentilis
.
