Scientists have discovered five new species of armored cave dwelling spiders in Southwest China. The researchers found the spiders after exploring over 2000 caves in South China Karts. A male of the newly described species, Sinamma oxycer, is pictured above. It has a reddish-brown body with yellowish-brown legs.

The armored spiders all belong to the family Tetrablemmida. They are distinguished by their armor-like abdominal pattern. Two of the newly discovered spiders belong to the genus Tetrablemma. Spiders of this genus are distinguished by having only 4 eyes.

The new spiders are fully described here in ZooKeys. The total known spider species of China has increased from 2300 species to 4300 species in the last 10 years.
