Abstract
A new species of Tullbergiidae, Paratullbergia chuana sp. nov. from Sichuan Province, southwest China is described. Paratullbergia chuana is characterised by the presence of one pair of pseudocelli on each segment from Th. I–Abd. V and a formula of 11/111/11111, postantennal organ composed by 34–50 vesicles arranged in two rows, seta px present on Abd. IV, setae a2 and a4 on Abd. V as macrosetae, p4 as mesoseta, and a less differentiated sensillum p3 on Abd. V. In addition, chaetotaxic variations on Abd. IV and V are discussed. An abnormal morphology of an antenna that was observed for the first time is reported.
