Original description: [Prauss, 2012]:

Diagnosis:
A species of Bosedinia with fine spines evenly distributed across the autophragm and a lack of alveolae.

Description:
Bosedinia spinosa is characterized by a scabrate cyst surface with evenly distributed, hair-like spines. Although present in abundance across considerable section intervals of the upper Turonian, no specimen was found to show a clear operculum outline. However, the flap-like character of the opening, its wide attachment to the cyst (Figs. 2J, K, 3J) and the frequent appearance of accumulation bodies (Figs. 2N, 3I) are taken as evidence for an affinity with Bosedinia.

Dimensions (in µm):
Holotype: length 67.2, width 61.45; spines 2.96 (3.59) 4.19.
Paratype: length 63.65, width 59.41; spines 3.56 (4.06) 4.73.
Other specimens: diameter (23 measurements) 41.7 (58.5) 68.65; spines (46 measurements) 3.22 (4.82) 6.03.

Affinities:
Bosedinia spinosa differs from all other Bosedinia species in having hair-like spines across the autophragm and in lacking alveolae.
