Acratia recurvata? Cordell, 1952

( Fig. 5C, D View FIG )

Acratia recurvata Cordell, 1952: 81 , 82, pl. 20, fig. 65. — Shi & Chen 2002: 81, 82, pl. 20, figs 19-24.

MATERIAL EXAMINED. — Three complete carapaces and 13 broken carapaces.

DIMENSIONS. — L= 499-1197 µm; H= 244-500 µm.

OCCURRENCES. — Oread Formation, Missouri, USA, Late Carboniferous ( Cordell 1952); Guangxi, China, Late Permian ( Shi & Chen 2002);?Chaotian section, Sichuan Province, China, Wujiaping Formation, basal Wuchiapingian, Late Permian (this study, samples: 11CHAO81, 11CHAO85, 11CHAO90, 11CHAO95, 11CHAO97, 11CHAO98, 11CHAO99, 11CHAO100, see Table 1).

REMARKS

Our specimens are very similar to A. recurvata Cordell, 1952 from the Late Pennsylvanian (Late Carboniferous) of Missouri ( USA; Cordell 1952) and Late Permian of South China ( Shi & Chen 2002) but differ in having a more concave AVB, a VB slightly concave at mid-L and the PDB connection with DB forming a more or less marked angle.
