Taxonomy

Catalog entries: Dictyomitra ascelis

Original description: Shell small, of six to seven or possibly more segments; cephalis and thorax together conical; abdominal segments subcylindrical, frequently elliptical in transverse section with greatest dimension in sagittal plane and little or no indentation at the strictures. Cephalis small, partly depressed in thorax, with no or very small blunt apical horn. Pores small, circular, irregularly arranged. Internally, four collar pores and paired ridges along cephalic wall from apical spine to sides of vertical spine. Postcephalic segments have small, circular, uniform pores increasing in size not at all, or only slightly distally. Thoracic pores irregular, or arranged in longitudinal rows; post-thoracic segments with pores in longitudinal rows, approximately thirteen to eighteen per half circumference on the fifth segment. Postcephalic segments increase gradually in size distally and the last observed segment constricts slightly to a ragged margin.
