Springtails, or collembola, are tiny arthropods. Their size ranges from 0.25 to 6 mm. Springtails normally live in damp soil. They eat mold and fungus.
They get their name from a spring-loaded structure, called the furcula, located on the underside of their abdomen. Most species have an tail-like appendage, the furcula, that is folded beneath the body to be used for jumping when the animal is threatened. It is held under tension by a small structure and when released, snaps against the ground, flinging the springtail into the air. All of this takes place in as little as 18 milliseconds and a jump can cover 10 centimeters.
This new species from China was named after the Changfeng Park where the type specimens were collected.
For the experts: The genus Paratullbergia Womersley, 1930 is recorded for the first time from China. Paratullbergia changfengensis sp. n. from Shanghai is described and illustrated. It is characterized by the presence of 1+1 pseudocelli on thoracic segment I, with two pairs of pseudocelli on each of thoracic segments II and III, presence of seta px on abdominal segment IV, seta a2 and p4 on abdominal segment V as microsetae, and less differentiated sensory seta p3 on abdominal segment V. Both sexes present. The new species can be easily distinguished from its congeners by the presence of pseudocelli on thoracic segment I. An updated key to the world species of the genus Paratullbergia is provided.
