Shishaella hastierensis Crasquin-Soleau, 1988: 312, pl 1 figs 1–4.

? Paraparchites sp. – Song & Gong 2019: fig. 4k.

Material examined

CHINA • 1 complete carapace (Fig. 7E); Blue Snake section, Tangbagou Formation, sample 19BAI 39; Tournaisian, early Carboniferous; P6M 3880 • 48 complete carapaces; Blue Snake section, Tangbagou Formation, samples 19BAI 01, 19BAI 02, 19BAI 08, 19BAI 16, 19BAI 23, 19BAI 27-2, 19BAI 37, 19BAI 39, 19BAI 43, 19BAI 44, 19BAI 55, 19BAI 58; latest Famennian–Tournaisian, late Devonian– early Carboniferous.

Dimensions

RV: L = 380–1176 µm, H = 271–886 µm, H/L = 0.71–0.79.

LV: L = 380–1193 µm, H = 276–918 µm, H/L = 0.68–0.77.

Remarks

Paraparchites sp. in Song & Gong (2019) from the Famennian, late Devonian, of Blue Snake section, Guizhou, South China (Song & Gong 2019) does not belong to the genus Paraparchites Ulrich & Bassler 1906 as indicated by the postero-dorsal spine on the illustrated right valve. The specimen shown in Song & Gong (2019) is only questionably attributed to Shishaella hastierenesis Crasquin-Soleau, 1988 because the occurrence of a postero-dorsal spine at left valve, which would point to the genus Shivaella Sohn, 1971, cannot be verified.
