Cryptamphorella sp. ( Fig. 5C )

FIGURED SPECIMEN. — ULVG-7332.

MATERIAL. — Eight specimens (recovered with the hydrogen peroxide method); 59 specimens (recovered with the acetic acid method).

DESCRIPTION

Three-segmented form with poreless cephalis, perforated thorax and large inflated abdomen. Thorax partially hidden into the abdomen. Pores of the thorax and abdomen are sub-circular and arranged in polygonal pore-frames.

REMARKS

This species differs from Cryptamphorella conara ( Foreman, 1968) in having apparently primary pores on the thorax, and by its less depressed thorax into the abdominal cavity.
