Eosestherioidea Zhang & Chen

LI, GANG, 2022, SEM morphological study of the Late Triassic clam shrimp Shipingia hebaozhaiensis (Spinicaudata, Crustacea) from Yunnan, southwestern China, Palaeoentomology 5 (4), pp. 298-304 : 299

Superfamily Eosestherioidea Zhang & Chen in Zhang et al., 1976

Diagnosis. The carapace outline is rounded, elliptical, ovate, oblong or rhombic. The umbo is small, located in the anterior part of the dorsal margin. Growth bands sparse or numerous; those near the umbo are ornamented with polygonal reticulations, which can transform to radial lirae on growth bands near the ventral margin ( Li, 2020c).

Remarks. Chen and Shen (1985) named the superfamily Eosestherioidea and credited the authorship to Zhang & Chen (in Zhang et al., 1976). But there was no diagnosis published at that time. The above mentioned diagnosis of the superfamily Eosestherioidea is a summary of the included forms ( Li, 2020c).
