Zhao Li introduced to Red Star News that cyclocosmia ricketti is a spider of the genus Discoptitis in the family Ceratophyllaceae, commonly known as the amputatia spider. The Richteropteran-bellied spider prefers to burrow holes in farmland stalks and preys on terrestrial arthropods.
The First Discovery of the Richteropteran In 1901 in the northern region of Thailand. "The country was discovered in 2000 in Lushan County, Ya'an, and its shape broke many people's perception of spiders. The abdomen is like being cut off by a knife, forming a strange flat circle shape, and there are unknown lines on it, like a mysterious seal, so it is also called 'seal spider' by many netizens.

Zhao Li said that the Richteropteran disc spider is one of the earliest spiders with written records in China from the morphological signs, and the Chinese name of its species is also recorded in the "Erya Shi Worm".
The reason why this spider is difficult to detect, Zhao Li speculates may be because of its special living habits. "At present, we have a live animal at the Huaxi Entomological Museum. According to observation, it usually lurks at the entrance of the cave, stretching forward two pairs of feet, when the prey passes through the mouth of the cave, it will rush out of the cave and pull the prey into the cave for food. ”
