A90E87CD9942FFD2FF4916CE1BA5BC71.taxon	type_taxon	Type species: Linglongtaestheria daxishanensis gen. and sp. nov., from the lower Upper Jurassic Tiaojishan Formation, Daxishan village, Linglongta, Jianchang County.	en	Li, Gang (2020): New Spinicaudatan Species of Late Jurassic Linglongta Phase of Yanliao Biota from Western Liaoning, China. Zoological Studies 59 (36): 1-8, DOI: 10.6620/ZS.2020.59-36, URL: http://dx.doi.org/10.5281/zenodo.12823420
A90E87CD9942FFD2FF4916CE1BA5BC71.taxon	diagnosis	Diagnosis: Carapace small or moderate to the lower end in size; oval or elliptical in outline; growth bands near the umbo ornamented with small-diameter (8 – 15 µm) polygonal reticulation; growth bands in the middle part of the carapace ornamented with evenly distributed puncta (2 – 5 µm in diameter); the ornamentation gradually transforms to small-diameter (16 – 27 µm) reticulation or radial lirae in the lower part of the carapace, puncta occurring within reticulation or radially aligning between radial lirae.	en	Li, Gang (2020): New Spinicaudatan Species of Late Jurassic Linglongta Phase of Yanliao Biota from Western Liaoning, China.

A90E87CD9942FFD2FF4916CE1BA5BC71.taxon	discussion	Discussion: The new genus is similar to Triglypta Wang, 1984 and Tianzhuestheria Shen et al., 2002 in growth band ornamentation in the ventral part of the carapace, such as the occurrence of evenly distributed puncta, small-diameter punctate reticulation and radial lirae with intercalated radially aligned puncta. But, it differs from the latter two taxa in having small-diameter polygonal reticulation on growth bands near the umbo. The new genus differs from Liaoxiestheria Liao et al., 2017 in that the latter lacks the reticulation and radial lirae ornament on growth bands in the ventral part of the carapace.	en	Li, Gang (2020): New Spinicaudatan Species of Late Jurassic Linglongta Phase of Yanliao Biota from Western Liaoning, China.

A90E87CD9942FFD5FCE7104F1891BD91.taxon	materials_examined	Material examined and dimensions: Holotype, displaced carapaces, NIGPCAS 163667 (L 1 – 1); a right valve, NIGPCAS 163668 (L 2 – 1); a broken right valve, NIGPCAS 163669 (L 2 – 2); displaced carapaces, NIGPCAS 163670 (L 2 – 3). Carapace measurements: number of growth lines,> 16, 24, 23, 17; length (mm), 4.6, 5.2, 3.6, 3.7; height (mm), 2.9, 3.3, 2.3, 2.5. Etymology: From Daxishan, a village located in the south-west of Linglongta. Diagnosis: Carapace of small or small moderate size; ovate or elliptical in outline; growth lines smooth, about 20 in total; growth bands near the umbo ornamented with fine, polygonal reticulation (diameter <20 µm); growth bands in the middle part of the carapace ornamented with evenly distributed puncta (diameter <5 µm); in the ventral part of the carapace each growth band is ornamented with puncta in the upper part, which transfer into punctate reticulation in the anterior part and radial lirae in the posterior part of each band. Description: Carapace small or moderate in size, ovate or elliptical in outline; umbo small, located at the anterior half of the slightly arched dorsal margin; growth lines wide and smooth, about 20 in total; growth bands near the umbo ornamented with polygonal small-diameter reticulation, reticulum diameter is about 8 – 15 µm (Figs. 3.2 and 3.4; Figs. 4.4 and 4.7); growth bands in the middle part of the carapace ornamented with evenly distributed puncta, punctum diameter is about 2 – 5 µm (Figs. 3.3, 4.5); growth bands in the lower part of the carapace ornamented with puncta in upper part (Figs. 3.5 and 3.8), and punctate reticulation in lower part of each growth band in the anteroventral part of the carapace (Fig. 3.8), and radial lirae intercalated with two rows of radially aligned puncta in the ventral part of each growth band in the posteroventral part of the carapace (Figs. 3.5, 3.7, 4.8); near the ventral margin, the punctuate zone is located in the upper 1 / 4 to 1 / 5 of each growth band (Fig. 3.8). Distribution: Lower Upper Jurassic Tiaojishan Formation at Daxishan, Linglongta, Jianchang, northern China.	en	Li, Gang (2020): New Spinicaudatan Species of Late Jurassic Linglongta Phase of Yanliao Biota from Western Liaoning, China.
