Atrypa aspera var. subkwangsiensis Tien (var. nov.); Tien 1938: 100–101, pl. 8: 1–4, 17.

Spinatrypa sp. A ; Ma 1998: 350, fig. 4G–K.

Material.—Around 200 well preserved shells.

Remarks.—Preliminary study of abundant specimens from the Shetianqiao section shows that S. cf. ninghsiangensis and S. sp. A from the Chongshanpu section ( Ma 1998) probably represent intraspecific variation. When Tien (1938) described the species, he did not designate a holotype. Study of Tien’s type specimens indicates that they may be divided into two morphological groups. Group A is represented by specimens 6280 and 6183 ( Tien 1938: pl. 13: 3, 4) with coarser ribs, wider interspaces, and fewer ribs (no more than 20); group B is represented by specimens 6181 and 6182 ( Tien 1938: pl. 13: 1, 2) with finer and more ribs (around 25). Group A is identical with the Spinatrypa specimens from the Shetianqiao section.

Occurrence.—Widely distributed in central Hunan; Middle to Late Devonian (Frasnian).
