Original description: Eisenack, 1958, p.411: Tenua hystricella
Tenua hystricella n.sp. (Taf. 23, Fig. 5-7)
Type : da sauf Taf. 23 Fig 5 and Präp . Ob. Apt Nr. 22
Diagnose: Similar to the previous species, but noticeably smaller: 56-75 µm long and 48-66 µm wide.
10 specimens, 75 types, 66 µm
Additions: Since the outside cover is smaller, the original shape is better obtained. The forked branches of the spines occasionally tend to fuse and then form short worm-like lines on the surface. Supports, which are to be interpreted as pylomas, are found in exactly the same way as in the previous species.
