Scytodes thoracica is a spitting spider, so called because it spits a venomous sticky silken substance over its prey. Its size ranges between 3–6 mm (0.12–0.24 in). The carapace is unusual in sloping upwards towards its rear end, whereas the abdomen slopes downwards.

It has six eyes instead of the eight spiders usually have. It has a wide distribution: found in "Europe, North Africa, Turkey, temperate Asia to China, Korea, Japan. Introduced to North America, Argentina, India, Australia, New Zealand."[1]

This particular spitting spider features the presence of silk glands in its cephalothorax. Besides the silk glands in its abdomen, the spider also has silk glands connected with its venom glands. In this way the spider has the ability to make venomous silk. Other arachnids may also have silk glands in their cephalothorax, such as the pseudoscorpions.
