2009 Haplophragmoides horridus (Grzybowski) ; Kender, Kaminski, and Jones, p. 500, pl. 5, fig. 8.

Material. Eight specimens from seven samples.

Description. Test free, planispirally involute coiled, laterally compressed with 4½ triangular chambers in the last whorl. The last chamber is much larger than the previous ones. Sutures incise, rounded periphery. Wall coarsely agglutinated. Aperture interiomarginal.

Distribution. Originally described from the Paleogene of the Polish Carpathians, and ascribed to Maastrichtian–Eocene by Kaminski and Gradstein (2005), H. horridus has been recently reported from the Miocene of Congo Fan ( Kender et al., 2009).
