Ceratocyrtis(?) cantharoides
Eucephalis hemispherical, with numerous conical to needlelike byspines, pierced by small, circular to oval pores; bars circular to oval in cross section. Ante and postcephalic lobes moderately developed. Internal skeleton as with genus (see Sugiyama, in press) but Ax is always wartlike. A extending outside cephalis and having one or two, possibly more short branches on the dorsal side. They form a flat, characteristic apical spine. V also extending into a short spine which is bladed or nonbladed and flatted in the sagittal plane. Thorax variable in shape from inflated conical to nearly cylindrical; bars thicker than cephalic ones; pores subcircular, distally aligned in longitudinal rows. Thoracic margin with numerous needlelike terminal teeth prolonged from thoracic ribs.
The generic assignment remains tentative since its smaller test and wartlike Ax are rather different from other species of Ceratocyrtis.
Height of test except apical spine 85-140 µm; maximum width of thorax 78-118 µm; length of apical spine up to 53µm; based on 24 specimens.
The name is derived from the Greek kanhtaros, a beetle, alluding to its spines. | | Sugiyama and Furutani 1992 |
