O’Dogherty et al.—Jurassic radiolarians from the Eastern Alps In the original description (O’Dogherty et al., 2006),


Theocapsomella included also some four-segmented nassellarians (e.g., Stichocapsa himedaruma Aita). On the other hand, a phylogenetic relationship of Stichocapsa himedaruma Aita and Stichocapsa convexa Yao was also assumed (see O’Dogherty et al., 2006, p. 441). New findings are in favor of the latter opinion (see Šegvić et al., 2014, pl. 1, figs. 21, 22).


Occurrence.—Lower Bathonian to lower Berriasian.

Family Minocapsidae new family Type genus.—Minocapsa Matsuoka, 1991a.


Other genera.—Crococapsa new genus; Doliocapsa new genus; Hemicryptocephalis Li, 1988; Hiscocapsa O’Dogherty, 1994; Praewilliriedellum Kozur, 1984 (syn. Hemicryptocephalis); and Quarkus Pessagno, Blome, and Hull in Pessagno et al., 1993.


Diagnosis.—Pyriform to ovoidal shell consisting in usually four segments. Last segment with or without an aperture. Lattice shell composed of small rounded to large polygonal pore frames.


Etymology.—After type genus. Occurrence.—Early Pliensbachian to Middle Albian.


Remarks.—This family is erected for genera included in the unnamed family pro Stichocapsidae used by O’Dogherty et al., 2009. The genus Aitaum Pessagno and Hull, 2002 is an excep- tion because it has a multisegmented test composed of three to four post-abdominal segments. Aitaum has more affinity with the genus Lantus Yeh, 1987a and other eucyrtidiid-type nassellarians.


Genus Crococapsa new genus Type species.—Sethocapsa hexagona Hori, 1999.


Other species.—Cyrtocapsa asseni Tan, 1927; Minocapsa aitai Hull, 1997; Minocapsa truncata Wu, 2000; Minocapsa? tansinhoki Hull, 1997; Sethocapsa accincta Steiger, 1992; Sethocapsa horokanaiensis Kawabata, 1988; Sethocapsa kitoi Jud, 1994; Sethocapsa lagenaria Wu and Li, 1982; Sethocapsa pseudouterculus Aita in Aita and Okada, 1986; Sethocapsa? subcrassitestata Aita in Aita and Okada, 1986; Sethocapsa? zweilii Jud, 1994; Sethocapsa hashimotoi Tumanda, 1989; Theocapsa simplex Tan, 1927; and Theocapsa uterculus Parona, 1890.
