Fellerites sp. 1

Fig. 5B

Material examined

CHINA • 1 complete carapace (Fig. 5B); Blue Snake section, Gelaohe Formation, sample 19BAI 67; P6M 3838 . • 7 complete carapaces; Blue Snake section, Gelaohe Formation, samples 19BAI 67, 19BAI 68, 19BAI 74, 19BAI 80. All from the Famennian, late Devonian.

Dimensions

RV: L = 595–625 µm, H = 388–423 µm, H/L = 0.65–0.68.

LV: L = 455–753 µm, H = 286–479 µm, H/L = 0.63–0.68.

Remarks

This taxon is rare in the studied material and is represented by poorly preserved specimens that do not allow for a specific attribution. It is morphologically close to Phlyctiscapha ? xiangzhouensis Wang, 1983 from the Lower Devonian of the Sipai Formation, Guangxi, South China (Wang 1983a). The specimen illustrated in Wang (1983a) lacks the small velate ridge parallel to the marginal ridge characteristic of the genus Phlyctiscapha . Its outline, the absence of velar structure or teeth along free margin and the carapace slightly compressed along free margin could rather pointed to the genus Fellerites Gründel, 1962 . Fellerites sp. 1 differs from Phlyctiscapha ? xiangzhouensis by its higher carapace, slightly stockier morphology and its smaller size (L = 1060–1360 µm, H = 660–920 µm, H/L = 0.62–0.76 for Phlyctiscapha ? xiangzhouensis).

Occurrence

Samples 19BAI 67, 19BAI 68, 19BAI 74, 19BAI 80, Gelaohe Formation, Blue Snake section, Famennian, late Devonian (this work).
