Material. SMF 23.238– SMF 23.242.
Description. Ramose colony, 2.2 mm in diameter, with 0.65 mm wide exozone and 0.9 mm wide endozone. Thin complete diaphragms in autozooecia constricted to exozone. Autozooecial apertures rounded to angular. Exilazooecia few, having a rounded to polygonal transverse section, restricted to the exozone, 0.09–0.12 mm in diameter. Abundant aktinotostyles in the walls of the exozone, originating from transitional zone between endozone and exozone. Acanthostyles absent. Walls granular-prismatic, 0.03–0.04 mm thick in the endozone; laminated, regularly thickened, 0.07– 0.15 mm thick in exozone.
Remarks. Ulrichotrypella omanica Ernst et al., 2008 differs from U. prima Romantchuk, 1967 in having larger apertures (0.21–0.38 mm vs. 0.20– 0.29 mm in U. prima ) and less abundant exilazooecia.
Occurrence. Aseelah Unit, Saal Formation, Lower–?Middle Permian; Batain Coast (eastern Oman). Zhongba Formation, Permian (upper Cisuralian–Guadalupian); Zhongba area of southwestern Tibet.
