Original Description
Test free, small to medium sized; initial[ly] trochospiral, later planspiral involute, biumbilicate; periphery rounded; peripheral margins strongly lobated; chambers spherical in younger stage, increasing gradual[ly] in size as added, become radial elongate in the adult, 6-7 on the last whorl; sutures distinct, incised, radial; wall calcareous, finely perforated with rare but distinct base spines on the last 2-4 chambers; aperture equatorial, at the base of the apertural face, bordered by a lip

Etymology: The name is deriving from the Monastery Rohia, in the vicinity of which is located the type section.

Extra details from original publication
Remarks. The species is somewhat close to Protentella nazcaensis (Quilty) [Clavigerinella nazcaensis, Quilty 1976]. Differs [from] this species by less incised sutures in the young stage and shorter and more robust radial chambers and less lobate peripheral outline
