Dotona sp.

Fig. 5U.

Material.—Upper Eocene, south-central Ukraine.

Remarks. —The verticillate cylindrical acanthostrongyle Ivanik 2003: pls. 18: 5, 19: 1; Fig. 5U) covered with spirally coiled rows of tubercles and with microspined heads can be found in the modern clionaid Dotona pulchella Carter, 1880 compare Calcinai et al. 2001: fig. 2a, b). However, the spicules of Dotona do not exceed 100 μm in length, while the spicules described by Ivanik (2003) are twice as long (200 μm). This type of spicules resembles also acanthostrongyles of acarnid Zyzzya (compare Z. fuliginosa [ Carter, 1879], van Soest et al. 1994: figs. 19, 20).
