Pseudoeucyrtis safraensis

Protozoa - Nassellaria - Eucyrtidiidae

Discussion

Named by Dumitrica and Gorican.

Original description: Test multicyrtid, spindle-shaped, elongate. Cephalis small, hemispherical; lacking apical horn. Following five to seven segments roughly trapezoidal in outline, increasing slowly in width as added; segments with polygonal pore frames arranged diagonally. Remainder of test slowly decreasing in width, mostly comprising a long tube; pore frames of tube larger, mostly rectangular, arranged linearly. Intersegmental constrictions indistinct, usually weakly developed on proximal part but always lacking on the terminal portion with linearly arranged pores.

Original remarks: Pseudoeucyrtis safraensis n. sp. differs from P. angusta Whalen & Carter 1998 and P. busuangaensis Yeh & Cheng 1998 in having linearly arranged pores. In P. safraensis the linear pore arrangement characterizes at least one third of the test. P. safraensis is similar to Foremania sandilandsensis Whalen & Carter 1998 in the alignment of pores, but differs in being proportionally narrower, distally more constricted, and in lacking a large, branched apical horn. Also, the pores of F. sandilandensis are arranged in both longitudinal and transversal rows (square pattern), whereas in P. safraensis they are arranged in longitudinal rows only.

Etymology: Named after type locality.
