Remarks. Thiodina nicoleti is the type species of this widespread genus. The species is the only known representative of the genus reported from Chile.The available descriptions are inadequate. The little information available is summarised below.

Material examined: No material available.

Diagnosis: All members of the genus, incuding T. nicoleti , have two pairs of bulbous spines on the ventral side of the first tibia ( Fig. 118 ).

Description (after Nicolet 1849 and Simon 1901). Male: Same form and size as the female, with the anterior legs darker in colour; the remaining legs are yellow, and the longitudinal stripes on the abdomen are almost black, and velvety; the intervening space is dark yellow; a broad white stripe covers the sides of the abdomen.

Female: long and narrow, cephalothorax rectangular, rounded posteriorly, of a red/coppery colour with a white median stripe and white stripes on the sides. Chelicera with four promarginal (three small) teeth and three (one small) retromarginal teeth. Abdomen a long oval shape, black with four white stripes. The two median stripes narrow and close to one another; the lateral stripes broader; ventral abdomen brown. L1 amber rounded and heavier, L2–4 yellow. Two pairs of short robust spines and two pairs of bulbous spines ( Fig 118 ) on the ventral side of the first tibia.

There is some variation in the colour. The cephalothorax may be darker and the abdomen greyer. The abdominal stripes may be more or less distinct.

Distribution. “Chile”.
