Australiella bondarenkoi
Australiella bondarenkoi, Vozzhennikova, 1967; Emendations: Lentin and Vozzhennikova, 1990, p. 41 and Lebedeva in Ilyina et al., 1994, p. 68-69, both as Chatangiella bondarenkoi.
Now Chatangiella. Originally Australiella, subsequently (and now) Chatangiella.
Tax. sr synonym of Chatangiella chetiensis (Vozzhennikova, 1967) Lentin and Williams, 1976, according to Lentin and Vozzhennikova, 1990.
Tax. sr. synonym of Chatangiella obtusa Lebedeva, 1988, according to Lentin and Vozzhennikova, 1990. - however, Lebedeva in Ilyina et al. (1994, p.67) retained Australiella (as and now Chatangiella) chetiensis and Chatangiella obtusa is now considered a taxonomic junior synonym of Australiella (as and now Chatangiellla) chetiensis.
Holotype: Vozzhennikova, 1967, pl.59, fig.1b, pl.60, fig.2; Lentin and Vozzhennikova, 1990, pl.4, figs.6-7; text-fig.17
Locus typicus: Khatanga depression (Northern Siberia), Russia
Stratum typicum: Santonian

Original description: [Vozzhennikova, 1967, p. 130-131]: (Translation: Lentin and Vozzhennikova, 1990):
Description:
Theca elongated along the longitudinal axis, somewhat convex equatorially and tapering towards the poles. Epitheca on the level of the upper edge of the internal body, truncated or not truncated. Apical margin broadly rounded with a short, blunt ending apical horn. Hypotheca with straight or slightly concave sides and with a single broadly or narrowly conical antapical horn situated at one side of the antapical margin. The other side of the antapical margin is obliquely truncatet or lies parallel with the equatorial plane. Transverse furrow equatorial slightly deflected to the left. Margin of furrow delineated by short, blunt terminated outgrowths. Longitudinal furrow represented by a depression running from the end of the transverse furrow to the antapex. Internal body large, oval and with its lateral walls closely applied to the sides of the theca. The walls of the internal body are thicker at the poles than elsewhere. The surface of the internal body and of the theca is granulose. Pylome ovally polygonal and corresponding in position to plate 3cr.
