Napora conothorax
Named by Carter & Dumitrica.
Original description: Cephalis indistinct externally and imperforate, included at the upper part of thorax. Apical horn threebladed, relatively thin and short, bearing a verticil of three spinules and terminating in a short conical spine. Vertical spine not visible outside. Thorax and cephalis forming a wide, short cone with longitudinal ridges on the upper part, especially on cephalis, and 3-4 prominent transversal ridges. Ridges interconnected by vertical crests forming rectangular depressions. Pores in single transverse rows between ridges. Feet strongly triradiate and recurved, long, and pointed, with thin ridges and deep grooves. Outer ridge of each foot extends outward from the area of the raised ridge.
Original remarks: The apical horn and the feet of this species resemble those of Napora latissima Takemura with differing only in that the feet are less divergent and less curved. The paratype from Oman is rather similar to the holotype and paratype from British Columbia but has less pronounced transversal ribs and longitudinal ribs are more visible. Although partly broken, the only preserved foot of this specimen seems to show characters similar to the feet of the holotype and paratype.
Etymology: From the conical shape of the thorax; noun.
