Description - Add description
Cephalis very small, roughly one-third of the diameter of the thorax, well separated from the latter. Thorax wall campanulate with large rounded pores, 5-8µm, while the pores on the thorax are larger, 5-15µm of a more irregular, rounded shape. The vertical and apical spines are cylindrical and well developed, with a length varying from 10 to 60 µm for the apical spine, while the ventral spine is considerably shorter, 5-25µm. In most cases, the lateral spines do not pierce the thoracic wall, however, the dorsal spine can be very often seen on the outside of the thoracic wall. | Bjørklund 1976 |
