Fam. Dysderidae. 
Genus Ariadna Aud. 
1. Ariadna hottentotta n. sp. 
Specimens. 66 adult and immature ?? from Kamaggas, Little Namaqualand, July 1904. 
Colour in adult reddish-yellow, the cephalothorax darkened on the sides of the head anteriorly, 
the two posterior pairs of legs somewhat paler, the two distal segments of the first pair more reddish ; 
tibia I often with a dark spot above and another on each side at apex; metatarsus I darkened at apex and 
often on the sides at the base as well ; abdomen pale-yellowish (or more or less discoloured), with a broad 
dorsal band of purplish-black extending from end to end; chelicera dark-red to reddish-black. 
Cephalothorax as long as the tibia and 1 /b~ Va of the metatarsus of first leg, narrowed in front, 
its width just behind the eyes s /b or less of the length of the first tibia. Ocular area narrow, the 
distance between the median and posterior lateral eyes scarcely or only sligthly exceeding the width of a 
median eye. 
Legs longish ; fourth femur thicker than the first; anterior pair of legs rather densely clothed with 
long brownish hairs, those below the femur forming a loose mane, those on the tibia fairly evenly distributed 
all round the segment, the lower ones somewhat longer, the pubescence, however, less dense and ruddy 
than in A. jubata Purc. (Trans. S. Afr. Phil. Soc, Vol. XV, p. 156, 1904) from the same district; first tibia 
at least as wide as the distance between the posterior lateral eyes. Metatarsus I equal to or only very 
slightly shorter than the tibia; I and II with a single series of stout spines on each side below, III with 
2 anterior and 2 posterior rows of 2—3 spines each, IV with 1 apical spine below and about 4 setae in the 
apical comb. Tibia I with 5 — 6 (rarely 4 or 7) spines in each inferior row, besides 3 (rarely 4) others on 
each side, II with 3 spines on each side above the inferior row, III with 2 posterior rows of spines and 
o— I anterior spine, IV unspined. Patellae unspined. Femora I — III with dorsal and inner distal spines, 
III sometimes also with an outer distal spine, the inner distal spines 2 — 3 in number on first femur, 
IV unspined. 
Chelicera with 2 small superior teeth; the inferior tooth obsolete. 
Length up to 8V2 mm - 
In all the other South African species of Ariadna the cephalothorax is longer than the tibia and 
half the metatarsus of the first leg and this is also the case in immature examples of hottentotta n. sp. 
2. Ariadna Hghtfooti Purc. var. 
1904, Pukoell, Trans. S. Afr. Phil. Soc, Vol. XV, p. 155 ($ from Caledon Division, Cape Colony). 
Specimens. I adult ? and I juv. from Kamaggas, Little Namaqualand, 1904. 
The adult 9 differs considerably in colour from the type, being of a deep reddish-black to quite 
black, with the cephalothorax faintly reddish posteriorly, the two posterior pairs of legs paler distally, the 
abdomen purplish-black, the lung-opercula pale-yellow, and a triangulär spot just behind the genital cleft 
also pale-yellowish. In spite of the difference in locality I could find no essential structural differences, 
which would Warrant the establishment of a new species. 
The cephalothorax is as long as the tibia and 5 /« ( 7 / 8 in the type) of the metatarsus of first leg. The 
ocular area and the tibia of first leg are slightly wider than in the type. The first metatarsus is exactlv
