Original description 壳体细小, 单列直简形,向口端逐渐增大, 壳体横切面呈圆形。 壳表面具非常细的, 不连续的条纹装饰, 缝合线较平。 初房圆球形，直径大于第二壳室， 因而明显突出于壳表。
其它壳室局圆形, 共见 8一9 个增长很缓慢的壳室, 室宽稍大于室高。 壳壁透明状, 由不规则的钙质结晶细粒组成。口面稍突起， 壳口圆孔状。 壳高 0.4 毫米; 者最大宽度 0.12 毫米; 初房直径 0.05 毫米; 壳壁厚 0.01 毫米 。
比较 当前所描述的新种很近似于 Nodosaria geinitzi Reuss, 但后者缝合线明显凹下, 而新种缝合线较平。另外, 新种与 Nodosaria fisheri Crespin 亦很相似, 但后者壳表条纹装饰粗, 较明显, 而新种壳表纹饰断续而不明显。从壳体纵切面观之, 新种近似Nodosaria bella Lipina, 但后者壳壁厚, 且未见有壳表条纹装饰。

The test is small and straight in a single row, gradually enlarging toward the aperture, and the cross section of the test is round. The test surface is decorated with very fine, discontinuous stripes, and the sutures are relatively flat. The first chamber is spherical and has a larger diameter than the second chamber, so it clearly protrudes from the test surface. Other test chambers are round in shape, with a total of 8 to 9 test chambers that grow very slowly, and the chamber width is slightly larger than the chamber height. The test wall is transparent and composed of irregular calcite particles. The aperture surface is slightly raised, and the test aperture is round hole shaped. Test height 0.4 mm; maximum width 0.12 mm; chamber diameter 0.05 mm; test wall thickness 0.01 mm. Comparison The currently described new species is very similar to Nodosaria geinitzi Reuss, but the sutures of the latter are significantly concave, whereas the sutures of the new species are flatter. In addition, the new species is also very similar to Nodosaria fisheri Crespin, but the test surface decoration of the latter is thick and obvious, while the test surface decoration of the new species is intermittent and not obvious. Viewed from the longitudinal section of the test, the new species is similar to Nodosaria bella Lipina, but the latter has thicker test walls and no striped test decoration. Origin and stratum: Jiaozi Mountain, Anshun prefecture, Guizhou province; Upper Permian Changhsingian stage. [details]
