Taxonomy according to Fossilworks.org. Quote from Zhang et al. 2003, p. 447:” The Chengjiang Lagerstätte yields several well-preserved Early Cambrian fossil assemblages (Zhang et al. 2001) from the Yu’anshan Member of the Qiongzhusi Formation in Yunnan Province, South China, consisting of a diverse suite of arthropods (Shu et al. 1995, 1999a; Hou and Bergström 1997; Zhang 1999; Zhang et al. 2000). One of them, small and relatively rare, was only briefly described based on a few specimens (Hou et al. 1991), and repeatedly considered to be a giant protaspis of a naraoiid by many authors (Fortey and Theron 1994; Chen et al. 1996; Hou and Bergström 1997; Hou et al. 1999; Luo et al.1999). Recently this animal was also recovered from the Middle Cambrian Kaili fauna of Guizhou Province, South China (Zhao et al. 1999). Diagnosis for Primicaris larvaformis according to Zhang et al. 2003, p. 450: “Small, protaspis-like arthropod; undivided dorsal shield with a pair of posterior spines and ten pairs of lateral marginal spines; on the ventral side, one pair of uniramous antennae followed by ten pairs of biramous limbs.” Camera lucida drawing of holotype (ELI12001012), from Zhang et al. 2003: Identified by oilshale using Zhang et al. 2003.
