Youti (meaning "larva") is an extinct genus of dinocaridid arthropods from the Cambrian Yu'anshan Formation of Yunnan Province, China. The genus contains a single species, Y. yuanshi, known from a larval individual preserved in a carbonate nodule. The internal organs are well-preserved and were studied using synchrotron scanning electron microscopy and X-ray computed tomography. The specimen shows lobopod legs, and a onychophora-like peripheral haemolymph system. Based on its anatomical characteristics, Smith et al. placed in the arthropod clade containing Anomalocaris, Opabinia, Pambdelurion and Kerygmachela.[1]
