Original Description

Wall type: The wall is layered and perforate, with a smooth or weakly cancellate
Test morphology: Planispiral or pseudo-planispiral, laterally compressed, 4-5 rapidly expanding chambers in the final whorl; final chamber, and up to three of the preceding chambers, radially elongate, at least one of these ending in either a terminal nub or cylindrical projection (‘proto-tubulospine’); proto-tubulospines are smooth and distinctly porous (although pore density may be reduced at the distal ends) in contrast to the true tubulospines of H. mexicana and subsequent species, which are usually imperforate; distal chamber ends can be inclined in an anterior, posterior or dorso-ventral direction and pseudo-tubulospines are commonly bent; aperture is a high equatorial arch with a smooth, broad lip; lips of relict apertures are commonly observed along the sutures of the final whorl; sutures are shallow and usually curved in a posterior direction.

Size:
Maximum diameter of holotype (excluding proto-tubulospines) 0.63 mm.

Etymology:
Named in honor of Joyce Singano, chief micropalaeontologist at the Tanzania Petrolem Drilling Corporation
